It should be running by default and is really hard to get rid of.

Look for the "rpcbind" process.

However, there are the doubt about how many memory "tail" uses.

In the time it took you to post this message, you could have
performed a trivial experiment and answered your question yourself.

dd if=/dev/zero | od -cv | tail -1000

In another window observe the 'tail' process size with 'ps', or
'top' ...

It stores internally all the received data ...

Any tail that did this would be quite unusable on large files.

Can you provide an example of the arguments you used and
output from iostat? Did the switches match the names?
(For example if your list contained c0t0d0s0, did you use -n).

2. still cuts the list off at 20

Isn't that why you used "-l 20"?

3, lists disks i don't care about.

depending on options, the disk goes on the left or the right....

And this matter why?
I think "-n" (names on right) is newer option, so perhaps
behavior is rooted in backwards compatibility.

w/o -l 20 i get far more output than i can digest. also, i can't get
things labelled by mount point.

Works for me, See below.
I think mountpoints are only given with "-n" output,
which seems sensible because names printed w/o -n don't
resemble anything from the output of "mount" or "df".

the thing just feels chaotic. is there something better?

For what specific purpose?

One thing that I think is a bug is iostat's interaction with /dev/fd.
For example I think if I have a file called 'disklist', that contains
the names of the devices to list, then

$ iostat -nxpm -l 10 <(cat disklist)

should work, and doesn't.

% iostat -nxpm # line numbers added by hand

Your disklist probably machted nothing, so iostat added 20 additional disks

If you use a disklist you should probably set -l 1 (or anything lower than

Hi all,

No, not normally.

Realize that the root filesystem initial (read-only) mount is
constructed directly by the kernel. There's no startup script that does
so, because it has to already be mounted to read the script.

If you're interested in '/', why do you have a dependency on usr?

When is the rootfs first mounted in the boot process?

A mount is constructed directly by the kernel as it boots.

It is mounted read/write by svc:/system/filesystem/root:default.

Is it ever
mounted in
read-only mode

yes. The initial kernel mount is read only. A pre-solaris 10 'boot -b'
will give you a shell before root is mounted read-write.

For Solaris 10, use 'boot -m milestone=none'.

I don't know what 'mount' is looking at. It will report / as
read/write, but in fact it is still read-only at that point.

or is Solaris fsck capable of checking filesystems that
are
mounted w/o damaging them?

no.

I don't know what 'mount' is looking at. It will report / as

Maybe you have an old /etc/mnttab file underneath the mnttab
mount point, and mnttab wasn't yet mounted?

I thought of that right after I got the machine back up, but didn't want
to set everything back up again. So I finally got around to trying
another test and that doesn't seem to be the case...

# umount /etc/mnttab
# df -k
# ls -l /etc/mnttab
-r--r--r-- 1 root root 0 Jan 21 2005 /etc/mnttab

So it really is the kernel view of the mounts, not a stale file.

The "early" mnttab has no flag indications at all (neither rw or ro).

# head -1 /etc/mnttab
/pci@1f,0/pci@1,1/ide@3/disk@0,0:a / ufs dev=2200008 0

So I think 'mount' just assumes that no flags equals read/write (which
isn't true in this case).

In fact.... I don't know how to mount this filesystem (explicitly) read
only. Now that I look, the mount_ufs man page doesn't show a 'ro'
option, and my attempts to do so fail.

# mount -r -F ufs -o remount /dev/dsk/c0t0d0s0 /
mount: /dev/dsk/c0t0d0s0 is not this fstype
# mount -F ufs -o remount,ro /dev/dsk/c0t0d0s0 /
mount: /dev/dsk/c0t0d0s0 is not this fstype
but...
# mount -F ufs -o remount /dev/dsk/c0t0d0s0 /
#

"normal" filesystems can be mounted read-only, so why were the ro | rw
options removed from the mount_ufs man page?

Question about setting up a Storedge 3310 - mirror. The 3310 has 12
drives, 2 channels. When creating the logical drive, I select 5 drives
from each channel (10 drives total) and select RAID1 (2 drives will be
saved for Global spares). I understand that the array will configure
RAID 1+0 and is also smart enough to setup the mirrored pairs across
both channels as described in this short Sun Doc:
http://sunsolve.sun.com/search/document.do?assetkey=1-9-71182-1

3 hrs later, after the drives are initialized, I see one logical drive,
but instructions are not clear how to setup the Solaris 9 OS to use
both controllers? I'm not sure how the dual channels are presented to
the OS? Or does the array deal with it all?

The 3310 will only give you a single host connection. (You could
connect another host to the array, or even the same host more than
once, but there isn't any way to get path redundancy and failover.)

Given two controllers, if one fails then it will just use the
other. Automatically and transparently. Works great. No interruption to
service.

(The downside to this is that you have to actively monitor the array to
check that both controllers are running, because the system might not
notice at all if one fails.)

Should I have setup 5 drives (channel 1) as RAID 0 and the other 5
drives as RAID 0 (channel 3), presented them both to the server and
used SVM to mirror across the controllers?

Definitely not. If you lose a disk in a stripe you lose the whole
stripe and all your data redundancy goes. If you want 0+1 to turn into
1+0, you need to do it all inside the array or all inside SVM.

Server is a V480 (Solaris 9), 3310 array firmware version 3.25, Fiber
channel

That doesn't make sense. The 3310 is a SCSI array, if you had Fiber
Channel it would be a 3510 (given the channels IDs you mention, it
sounds like you do have a SCSI based 3310). But if you did have a 3510
then my notes are here:

Thanks for the help Peter,
You're right, the 3310 is SCSI and not fiber. (You know how it goes
whenit's late).

Yup. ;-)

you stated:

The 3310 will only give you a single host connection. (You could
connect another host to the array, or even the same host more than
once, but there isn't any way to get path redundancy and failover.)

Here's what I see with a format though:

0. c1t0d0 <SEAGATE-ST373307FSUN72G-0307 cyl 14087 alt 2 hd 24
sec 424>
/pci@9,600000/SUNW,qlc@2/fp@0,0/ssd@w2100000c50ebb5f7,0
1. c1t1d0 <SUN72G cyl 14087 alt 2 hd 24 sec 424>
/pci@9,600000/SUNW,qlc@2/fp@0,0/ssd@w21000011c62a46e2,0
2. c4t1d0 <SUN-StorEdge3310-0325 cyl 65533 alt 2 hd 64 sec 341>
/pci@8,700000/pci@3/scsi@5/sd@1,0
3. c6t1d0 <SUN-StorEdge3310-0325 cyl 65533 alt 2 hd 64 sec 341>
/pci@8,700000/pci@2/scsi@5/sd@1,0

So you have two SCSI connections to the array?

4. c8t40d0 <SUN StorEdge 3511 327R 91647800>
/pci@8,700000/SUNW,qlc@4/fp@0,0/ssd@w216000c0ff80670d,0

Items 2 and 3. I have two LUN's - 682GB each. I assume one LUN from
each side of the 3310. Based on what you stated, I would expect to
see one LUN. Do I now use SVM and create submirrors between 2 and 3?

How many logical drives have you created? You say you've created just
the one (mirror with 10 drives - which would be the right size if you
have 146G drives). What does the sccli "show ld" command give you?

If you've just created the one logical drive then you're just seeing
the same LUN twice - by different paths. In that case, really bad
things can happen if you try and access it from both paths. (As far as
I know, it isn't possible to use mpxio to use both paths in the same
way you can for a fiber array.)

My question is: If I change to Primary (so I can use sccli sub

Now, I don't know what's going to happen. I've never tried what you're

guess based on my understanding of how the thing works.

My guess is that if you move it from the secondary to the primary
controller then it will change the ID from t1 to t0 (so c4t1d0 becomes
c4t0d0). It won't destroy any filesystems or anything like that, but
you would have to go through the system so that Solaris knows to look
in a different place.

Good morning, gentlemen! A very interesting post.

I am about to set up a 3310 (probably a 3320, actually, but I presume
they are essentially the same as far as config goes?).

Pretty well. The 3320 is Ultra320, while the 3310 is Ultra160. And they
do take different firmware (new patches for both were released today)
so don't try applying 3310 firmware to a 3320 (or vice versa). But as
far as configuration goes I haven't noticed any differences.

I presume from
the post that you both have the RAID controller option. We're not going
to go with the RAID controller, due to cost considerations. Rather, I
was planning on simply using SVM for the system's boot disks, and use
the 3310's disks via raw access for a Sybase database.

I wonder if I could trouble you to elaborate a little on some points
made earlier:

Peter Said:
The 3310 will only give you a single host connection. (You could
connect another host to the array, or even the same host more than
once, but there isn't any way to get path redundancy and failover.)

Given two controllers, if one fails then it will just use the
other. Automatically and transparently. Works great. No interruption to
service.

and later when BD noted that he had 2 SCSI connections to the array and
was seeing 2 disks:

.... disconnect the SCSI cable from the
host. You don't really want this to be accessible, as it's just asking
for trouble.

One of the things I was hoping for in purchasing these arrays was the
dual-path redundancy (which it sounds like I'm not gonna get).

Well, SCSI is intrinsically single-path - unlike FC disks which are
dual-ported. So with JBOD you could have one path to a disk and a
different path to its mirrored (on the host) partner.

Is this
to say then, that even if I order a pair of PCI SCSI cards that I
shouldn't connect both of them?

With a RAID controller, you shouldn't. With JBOD, you should, and split
the busses so you attach half the disks to one card and half to the other.

My past experience had been with
Veritas which recognized automatically 2 paths to the same disk(s) and
presented you with only the one, even though you could see both from
format.

That's a good point. I hadn't thought about Veritas (previous
experience makes my mind blank it out - oh the pain!). I don't actually
know what Veritas would do with it.

I realize we may be talking apples and oranges here since you're using
the RAID controller (again, I'm presuming) and we won't be, and also
we'll be accessing them as raw devices, but is what I'm planning
feasible/recommended? Any alarm bells going off in your heads?

If you take out the raid controller, then I would run with a dual-bus
configuration. Connect one half of the disks to one card, the other
half to the other card, and then create mirrors (either SVM or within
Sybase) between disks on the two controllers.

In other words, split it in half and treat it as two 6-disk arrays that
happen to be in one box.

Note that the rules for JBOD and the rules for RAID are different.

iostat will give you some more info here.

Top isn't the best tool to use on Solaris (use prstat instead), but
more to the point, if your files are static, they'll be cached in
RAM by the kernel anyway (more pressing needs for RAM nothwithstanding).

Our web tier is running Sun Solaris 8. How could we tune/convince
Solaris to load more cached content into memory and reduce disk I/O.

Use performance analysis tools like iostat to make sure you are actually
disk I/O bound before you do any tuning. But I will say this: you will
very likely see a significant performance increase if you upgrade those
servers to Solaris 10. Upgrading to Solaris 10 will also enable you to
use DTrace to help identify any performance bottlenecks. (If you can
wait a week or two, you'll be able to use SOlaris 10 6/06, which comes
with ZFS...)

Daniel,

I agree with Rich's comments. We need to see the iostat data for those
drives housing your content. Also some network and cpu statistics and
maybe some vmstat data captured during a time when the systems is
experiencing the performance issue.

The V440 I believe has the Sparc IIIi processors so depending on how
much network bandwidth you're trying to support the system could even
be CPU bound at times. Is the content storage direct attached? What
kind of storage is it. A fibre channel SAN of course would be very
expensive but if you have to have faster storage then a midrange SAN
solution might be a reasonable thing to consider but I wouldn't insist
on active/active. That would likely add significant cost and it is
really hard to believe it's needed for a web server. You can configure
an active passive array such that you can utilize 2 or more HBA's on
the host side. I can provide details if needed.

Also, a selling point for the SAN idea is that it would open up shared
storage clustering possibilities for you.

Good luck with resolving the problem.

Regards,

Vic Engle

prstat won't display anything similar to that above (physical memory usage),
so why use it if it cannot give me the information I'm interested in?

Actually, this isn't obvious. Disks are fairly fast, networks
(affordable wide-area ones anyway) somewhat less so, high-traffic web
sites stress the TCP/IP stack.

On the other site the output of top shows the following:

It does that anyway. Solaris will use all free memory as a disk
cache. So you already have a disk cache of 5G or so (based on the top
output).

Assuming that you have some basis for your 3-4G number, then that
should be the effective working set and everything should be cached in
memory already.

What do your apache traffic, network traffic, and disk I/O actually
look like? Request rate, average request size, network utilization,
disk read/writes and transfer sizes? Do you know whether it's file I/O
or directory lookups that are loading your disks?

You could try Solaris NCA, which is a direct kernel cache.

Thanks.

"man pcfs". Perhaps you should mount using PCFS_MNT_FOLDCASE option.

That causes all file names to be mapped to lower case, which probably
isn't what's wanted.

Normally FAT filesystems are case-preserving; files retain the case
with which they were created, though you can't have two files in the
same directory whose names differ only in case, and you can refer to a
file "foo.txt", as "FOO.TXT, etc. Perhaps there's a bug in the
Solaris implementation of pcfs?

A good workaround is to copy a zip file or tarball to the USB drive,
rather than copying the files directly. That way the contained file
names are stored in the file itself rather than in the filesystem.

Ken,
The following excerpt from the solaris express pcfs (7) man
page seems (at least to me) to account for the observation made by
the OP. I agree PCFS_MNT_FOLDCASE may not do just what OP wants...
Had he asked how to preserve names in transfer, rather than how to
supress peculiar case wrap of file names already on the USB drive,
I would have offered the same advise as you.

Bob
File Systems pcfs(7FS)

When creating a file name, pcfs creates a short file name if
it fits the DOS short file name format, otherwise it
creates a long file name. This is because long file names
take more directory space. Because the root directory of a
pcfs file system is fixed size, long file names in the root
directory should be avoided if possible.

When displaying file names, pcfs shows them exactly as they
are on the media. This means that short names are displayed
as uppercase and long file names retain their case. Earlier
versions of pcfs folded all names to lowercase, which can be
forced with the PCFS_MNT_FOLDCASE mount option. All file
name searches within pcfs, however, are treated as if they
were uppercase, so readme.txt and ReAdMe.TxT refer to the
same file.

This is a Microsoft bug.

M$ ignores the case and even lists filenames that fit into 8.3 as
lowercase.

M$ uncorrectly creates FAT uppercase names for a lowercase filename
that fits into 8.3

If you use Solaris to create the filenames, Solaris correctly uses VFAT
names ;-)

Hi Kyle

It sounds like maybe the box is getting hammered - Is it really busy? There

are steps you can take to tune the stack on Solaris boxes, you can make

changes to set numerous variables in order to increase throughput.

Below is a script I use when setting up web servers (Sol 10) which seems to

increase throughput - YMMV of course, and I wouldn't blindly apply the

script, take some time to work through it and identify if it would be useful

to you. Some features may not work on older Solaris versions, again YMMV.

http://docs.sun.com/app/docs?q=tunable+parameters+solaris is very useful.

As far as I'm aware the alert is generated when the box thinks it's under a

SYN flood attack (and the unestablished connection queue becomes full).

/dev/tcp tcp_conn_req_max_q0 - unestablished connection queue (incomplete

handshake)
/dev/tcp tcp_conn_req_max_q - established connection queue

Are two parameters that you can tune in order to increase the queue sizes.

http://www.informit.com/articles/article.asp?p=101138&seqNum=5&rl=1 has more

Right, and then I'd have thought netstat would have showed

with a very low transfer rate(4048), why is that so see below from
iostat during a level 0 dump.

The machine is a E250 and all disks in the machine are brand new Maxtor

4064.1 KB/sec divided by 127.0 writes/sec = 32 KB writes.

This is too small for LTO. LTO minimum for reasonable performance is 256
KB writes.

Performance is crawling because LTO drive has to slow down. You are not
feeding data to it fast enough for it to run at full speed.

Bottleneck here is how you are using ufsdump. Your tape drive and hard
drives are fast. :)

You might want to try ufsdump's 'b 512' argument to tell it to write
data to tape in 512 block chunks (256 KB).

ufsdump may limit it to 126 block chunks; not sure, so test and verify.

Ummmm, well then, yes you *do* know the average, it's 73KB,
and yes, that qualifies as lots of little files. There is nothing
that will back this up as fast as you (apparently) want. Star
will be faster than gtar or ufsdump, but not 10X faster or
anything like that.

Search this group for "Backup tools too slow" and you'll get some
education.

service in spare time in our company, otherwise we would have MS
everywhere :)

But the backups would still be slow. :-)

2. If installa 5'th disk in the E250(which makes a total of 5 147 GB
disks), would some kind of SW raid help this?

Striping would help a little bit, but not 1.5X or anything like that.
It doesn't sound like you're ready for that in any case.

3. We where planning to more to S10 in december last year, but S10 was
delay(update) so we are still on S9, would S10 and ZFS help us?

You're getting 4MB/s IIRC, that's not bad. ZFS might help a little,
but ZFS provides flexibility and control, not so much improved
speed. ZFS cannot change average seek time on your drives.

What you *can* do is reduce the amount of time that live
data changes on the drive reduce the integrity of your
backup. The "backup window". You do this by either taking
a snapshot of the file system, and backing up the snapshot,
or doing an additional mirror of the file system, and do a
detach/backup/re-attach of that extra mirror.

ZFS makes the snapshot pretty easy. You can snapshot
your UFS filesystems, too, see fssnap. Last time I tried
incremental ufsdump on fssnap snapshots, it didn't handle
the timestamps correctly, but that was on Sol8, maybe
it's fixed now.

I reiterate, you should search this group, you'll get a lot
of good information.

extra security...

I don't need an entry in routing table,
neither need I an IP address in the global zone,
in order to filter or RDR the packets for a non-global zone's subnet.

And when it comes to using routing daemons (in.routed / routed)
which can IMO be a very important part of a somewhat more advanced
router then your argument becomes plain out wrong.

Again, routing and firewalling are two very different activities.
Your statement is perfectly correct for routing but wrong
for packet filtering and NAT/RDR. Please give an example of
advanced firewall that needs a routing daemon.

There is no 'security advantage' to be gained here since the actual routing
will always be done on the global zone.

There's no routing in the global zone, but RDR tables only.
No routing daemons, either. Just a kernel module.
Totally different level in OS as well as in the IP stack.

The only real security advantage is to place network services
(http, mta, etc.) servers in your non-global zones.

I agree, but this has nothing to do with the topic.

Security advantage here is that administrator can avoid any
management traffic on subnets *and* any rule managenent activity
in virtual hosts being filtered, NATed or RDR'd.

Even though I use a separate Solaris 10 box as dedicated firewall,
I still consider it reasonable to configure the extranet and intranet
IP addresses in two separate non-global zones, and use a third
non-global zone (on a separate physical segment) for interactive
access.

From this management zone, I can ssh to a global zone via internal

virtual interface not visible from "production" zones.

Comparing with a traditional 3-segment firewall (intra, extra, mgmt),
I assign this 3 "functions" to 3 isolated machines, which gives me
some additional piece of mind.

Regards,
Andrei

This is Solaris 8 and it has lsof installed.

however these wont't be only fds to files (network sockets too, etc).

Ask Sun to remove the arbitrary minimum of "nbpi=1048576" for EFI

filesystems with lots of inodes take a long time to fsck. To me
a potential performance issue might justify a warning message and
a change in defaults, but not a hard limit.

If you can get by with .99T you can get as many inodes as you need.
Based on the df output you presented your current inode density is
around 211k so you could use "newfs -i 100000" on the .99T filesystem
to get a little extra usable space by making fewer inodes.

ZFS doesn't suffer from this limitation. I've also heard that with
the sources from OpenSolaris it is easy to bypass the EFI inode limit.

Yup. It's really simple. You can get a premodified version from:

One problem with this many inodes is that fsck will use a *LOT* of RAM

Thanks to Jim and Peter on this. I opened a ticket with Sun and indeed
they told me the limitation for TB filesystems is 1024*1024 / TB. I
will ask sun to remove this limit as part of my ticket, but I will not
hold my breath.

I am going to look at ZFS again, but it is still not clear to me if it
is in general release, i.e. supported under Solaris 10. (3/05 or 1/06).
Maybe it is time to start testing ZFS on some QC systems.

I need advice when configuring ntp on cluster.

For now it uses /etc/inet/ntp.conf.cluster and server 127.127.1.0 as time

But because of that this cluster at this moment 12 minutes faster than my

whole environment.

I haven't set up a cluster, although I have used ntp a fair bit.

My advice would be that you need to get your clock calibrated
on every server before you set them up to try to run independently.
The most straightforward way I can think of to do that is to run
ntpd against an external server for a week or so, then let it build
an ntp.drift file that it can use to compensate for the natural
drift of the system's clock.

How can I configure it to use external ntp server?
As I can see, /etc/init.d/xntpd.cluster stopes when it find

/etc/inet/ntp.conf, so I assume I should still use

/etc/inet/ntp.conf.cluster.

Can I simply change field "server 127.127.1.0" to i.e. "server

ntp.server.my"? Will nodes be still synchronized than?

If you have Internet connectivity available, the easiest thing would
be to just synchronize your servers to external servers. If you
really want to ensure that your local machines stay in sync with
each other, you can solve that in one of at least two ways:

(1) synchronize each internal server with enough external servers
that the chances of one of them being far off is really small,
just because it would require too many failures (of external
servers) for that to be likely to happen, or
(2) synchronize one server with external servers, then synchronize
your other servers to it; then your internal servers will not
all be on equal footing because one will be the master, but
they should still stay in sync for a while if you lose internet
connectivity for a day or two.

In general, keep in mind that just setting up a cluster of servers
trying to sync to each other will not give you reliable and
accurate timekeeping. Computers make OK clocks but not good ones,
and in order to keep in sync, you need to ultimately be drawing
your information from a good clock (either from a public ntp server
or from a hardware clock, like a GPS receiver).

My actulaf conf files are (both same):
server 127.127.1.0
peer clusternode1-priv prefer
peer clusternode2-priv
driftfile /var/ntp/ntp.drift
filegen peerstats file peerstats type day enable
filegen loopstats file loopstats type day enable
filegen clockstats file clockstats type day enable

how should they look after I switch to external ntp source?

Just look at what they suggest doing at http://www.pool.ntp.org/ .
If you are in Europe, you should be able to put

server 0.europe.pool.ntp.org
server 1.europe.pool.ntp.org
server 2.europe.pool.ntp.org

and remove all the "peer" lines, and that should probably do it
for you.

Hi all

To settle an argument here, can the T1000 support 2 internal drives, or
only one? I've had conflicting advice from Sun representatives.

We've just got hold of one of these units, with some more to come.
There is only physically room inside for one SATA drive - although if
you follow the SATA cable from the drive back to the motherboard, it
appears there is is another similar connector right next to it. I'm
guessing that you could probably hook another SATA drive up to it and
it would work - but you'd have to get the power to it from somewhere
(there's only one drive power connector as well), and find some way of
shoe-horning it in there with the other drive, and face all the
additional problems of airflow and cooling etc., not to mention voiding
your chance of ever getting support for it!

So, the answer is pretty much "no", although I suppose in theory you
could probably do it somehow. You have got a single PCI-E slot though,
so if you need extra storage, you could always use a PCI-E fibre HBA
(there's one that's intended for the T2000 that fits and I see they've
now qualified it for use in the T1000) and hook up to more storage that
way...

I've tried the -ac option, but that did not help. I'm not sure what the

*Assume:*
- Solaris 10 or OpenSolaris
- Three physical network adapters (bge0, e1000g0, & e1000g1)

Sure the router works fine, but that is not the point of this exercise. The
ultimate goal is to learn more about networking and Solaris while securely
setting up Solaris for internet/LAN connectivity on one box.

Then I'd suggest leaving the router as it is and start by becoming more
familiar with Solaris. If you wish security then the first thing to

accomplish
is becoming more familiar with the OS.

Is is possible to setup Solaris so that one zone is created and dedicated to
the WAN (bge0) and that all outgoing traffic from global zone LAN NICs
(e1000g0 & e1000g1) route to the ISP through the WAN zone

That and not feasible too. I suggest you check the Sun website and perhaps
opensolaris website on the topic of zones. Its a virtual machine, but one
running on the same kernel and limited in some ways, like control over the
routing table.

Am I totally missing something by even suggestion this setup?

Yes, some basic understanding of zones.

First ask yourself why you'd want zones. Just because you can might not give
you the results you want. IMO a better approach would be using a zone to run
specific network services which are exposed to the Internet so that in a case
of an attack or worse you can limit the damage.

Does a much better/simpler method exist, given the background goals, that
I've overlooked?

Too many to even begin mentioning them all.

First keep on using the router untill you're more familiar with Solaris.
Personally I'd dump stuff on the global zone first, then see what might be
suitable to run in a zone.

oh; and I absolutely wouldn't try and use opensolaris ('Solaris Express') for

a
gateway/firewall. Even though its not that unstable its still but a snapshot

of
the upcoming release, one which doesn't get any security updates (unless
ofcourse you get a support contract from Sun).

So stick to the plain 1/6 release.

It might be arguable that it's in fact *global* zone that routes the traffic
in this scenario. But look, global zone may have no valuable IP address

Then routing would be hardly possible since you /need/ an entry in your

routing
table to allow the global zone to access the non-global zone. So much for the
extra security...

And when it comes to using routing daemons (in.routed / routed) which can IMO
be a very important part of a somewhat more advanced router then your

argument
becomes plain out wrong.

There is no 'security advantage' to be gained here since the actual routing
will always be done on the global zone. And as such the actual routing is

also
performed there. The only real security advantage is to place network

services
(http, mta, etc.) servers in your non-global zones.

on a subnet where a "router" zone acts. How does it route it then? ;-)

Because the non-global zone is in the routing table of the global zone. There
is no actual routing here since the data will never leave the system anyway.

That doesn't sound good.

Am I right to say that there is problem getting respond from dns?

Yes, it sounds like it. At a guess, you're missing IN PTR records for
in-addr.arpa (reverse name resolution).

Is there a way to show that the server submitted a request but failed
to get reply from DNS? The reason why I need this is becuase the
servers (more than one) next to this don't have this problem.

Only (easily) by watching the network traffic from your machine using
something like snoop. For example in one window, type "dig www.eg.com" and
then run snoop in a different window before pressing return in the first.
You'll get something like:

# snoop -r udp and port 53
Using device /dev/e1000g0 (promiscuous mode)
172.16.0.138 -> 172.16.0.2 DNS C www.eg.com. Internet Addr ?
172.16.0.2 -> 172.16.0.138 DNS R www.eg.com. Internet Addr 62.3.217.251

The output should be pretty self-explanatory ;-)

Note the "-r" to stop snoop from trying to resolve any IP addresses during
output, which would confuse any attempts to diagnose name resolution
problems...

PS: This is my first time using snoop

You might find ethereal easier to use, but I don't want to force
another tool on you while you're in the middle of troubleshooting ...

Is it easy to use?

Yes, though it uses X and needs root, and is perhaps a bit of a
sledgehammer. It /is/ a great tool to know how to use, but like James said
it might be a distraction at this point for you.

Cheers,

Chris

Hi,

The server was not able to connect to the network. When arp -a was issued,
the response from the server was very slow and initially the Mac address of
the gateway was blank. When arp -a re-issued, the gateway entry was not
listed. After I did a reboot of the server, the gateway entry is back in the
arp table.

Is there a way to investigate why the arp table lost its data so as to
prevent future occurrence?

Server: E4500
OS: Solaris 8

Thanks in advance.

"arp -a" just displays entries in the cache, it doesn't do anything
to "populate" the cache. Entries in the arp cache time-out so before
being concerned about a "missing" entry you should try to "populate"
the cache, say by first "pinging" the hosts (on your subnet) in question,
or possibly transmitting a "broadcast ping". (Hosts may be configured
to not reply to a broadcast ping, or may filter ICMP echo requests,
so this may not help).

For example if your net is 192.168.0.0/24 you could ping the broadcast
address by:
% ping -s 192.168.0.255
^c
% arp -a

If you are experiencing a delay, its probably due to a name resolution
problem. Try "arp -an" to skip the reverse lookups.

about that (will test that as soon I have physical access to the

Followup - yes, the problem was the OpenBoot firmware. After an

just fine.

Any suggestions on the best driver to use? I assume download one from
the Nvida site?

I'm a newbie to the OpenSolaris world and had pretty much the same exact
experience.

I've not been using OpenSolaris - I had tried Solaris Express, but are having

problems installing that. I think it might be a DVD creation problem now, as

I can get it to boot from a CD properly, but only half-boot from a DVD.

During the install the VESA mode was usable but, alas, there
was no permanent configuration for X installed and the subsequent reboot
after successful install meant no X.

It seems this is a problem, which might be easily fixed. One assumes if a

driver works once, it should work again. But perhaps the issue is during

install the driver is 32-bit, but then needs to be 64-bit - for my Opteron at

least. I'm not sure what CPU you have.

I found that the xorgconfig text based
script produced very close to a functional xorg.conf if the same VESA mode
was used. This at least made X usable but unable to get out of VESA mode as
the nv driver simply wouldn't work.

I'm currently using JDS and found that after installing the new drivers from

the Nvidia site, and and following instructions from here:

http://www.phoronix.com/scan.php?page=article&item=406&num=1

I got it working. Briefly, that needed.

# /usr/X11/bin/scanpci

where it produced an output similar to this for me.

pci bus 0x0004 cardnum 0x00 function 0x00: vendor 0x10de device 0x0141
nVidia Corporation GeForce 6600 GT

Then I needed to run

# update_drv -a -i '"pci10de,0141"' nvidia.

and do a reconfigure boot.

Should probably mention my card is a PNY 6800GT AGP card on an old KD7A
KT400A chipset mobo. The AGP port driver in FreeBSD did not support this
AGP port

I'm not using AGP, but PCI Express

I realise it must be hard with all the different hardware around, but this

really need to be sorted out whereby failures like this occur. Two things

happened that I think should be avoided.

1) The install picks the wrong driver. There should at that point be a stage

where it tests the driver, tells the user it is testing, and asks them to

report if it works or not. Currently the default is to use it without doing a

test. Sure you can test, but most will not.

2) After selectomg a driver that allows the install to go ahead, and spent

some time answering all the questions about networking etc, it is annoying to

find you can't see anything sensible. If the driver has worked during the

install, I'm not sure why it should not work once the isntall is complete.

Perhaps though, a dirrferent driver must be used, sicne one is 32-bit and the

other 64-bit. I guess that is harder to check, unless the installer can be

forced to work in 64-bit too, so at least one is testing the same driver.

Hi all,

Hi there

I am trying to configure the network interface in a Solaris 10
workstation (I had skipped this step during installation). This is the
first time I'm doing this. I did read up some articles, man page and
older posts in this newsgroup, but still a little confused about the
exact steps to follow.

I understand that I have to configure the interface by the following
command line:
# ifconfig e1000g0 xx.yy.zz.ww broadcast xx.yy.zz.255 netmask
255.255.255.0 plumb up

1. To run the above command, I need the IP address xx.yy.zz.ww of the
host. I'm trying to get it through DHCP. I followed the instructions at
this webpage: http://www.rite-group.com/consulting/solaris_dhcp.html
(create the files /etc/hostname.e1000g0 and /etc/dhcp.e1000g0 manually
and reboot). After reboot, I was expecting that the IP address for this
interface will be shown. But this is what I got:
# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu
8232 index 1
inet 127.0.0.1 netmask ff000000
e1000g0: flags=1004802<BROADCAST,MULTICAST,DHCP,IPv4> mtu 1500 index 2
inet 0.0.0.0 netmask 0
ether 0:3:ba:f1:3f:fe

It looks like the interface hasn't come up - try # ifconfig e1000g0 up

At this point I figured that I could have done the same as above using
ifconfig command itself, so wanted to see if it makes any difference
(that is, if it can assign the IP address). So my next command was:
# ifconfig e1000g0 auto-dhcp primary wait 120
ifconfig: e1000g0: interface currently has a pending command (try
later)

Confused, I wanted to see if the following command would work.
# ifconfig e1000g0 plumb
ifconfig: SIOCSLIFNAME for ip: e1000g0: already exists

The interface is already plumbed in, you can't plumb it in twice. To remove

it and start afresh, try # ifconfig e1000g0 unplumb

So how do I get the IP address?

The easiest way to start this process again would be to run "sys-unconfig"

and follow the prompts.

2. How do I know the name of the network interface? It took me some
time (reading older posts and checking /etc/drivers_aliases) to figure
out that it is e1000g0 in my case. Is there an easier way?

Try a prtconf - you should get the driver name and instance from this. In the

case below, we can see 4 interfaces, ipge0, ipge1, ipge2, ipge3.

# prtconf -D |grep network
network, instance #0 (driver name: ipge)
network, instance #1 (driver name: ipge)
network, instance #2 (driver name: ipge)
network, instance #3 (driver name: ipge)

Thanks for your help.

No worries.

There are two varieties of each card, qlogic and emulex.

Can the 3510 array support 4 GB speeds in direct connect configurations

You could use the 4GB card directly with the 3510, it will use the 2GB speed.
Since the 4GB is the same price as the 2GB, take the 4GB, IF YOU HAVE SERVERS

If you use pci-express, take the fastest available. (T1000, T2000, X2100)

Hi all,

quick question - working on a automated solaris 10 build for our
customers, and they support a number of different HBA's and Storage
arrays - I wonder if anyone has come across a good reference point for
suggested Kernel Tunables for storage within solaris

for some of detail - HBA's are a mix of the usual suspects from Emulex
and Qlogic
Storage arrays are (again) usual suspects from EMC / HDS etc.

any words of wisdom would be greatfully recieved.

Many thanks,

Stuart

Emulex, I think, had a good write up on Solaris kernel settings for

Hello,

You should find some usefull PDF's according Qlogic on:

http://support.qlogic.com/support/drivers_software.asp

You must find model of HBA - there will be some info about tunable
parameters according kind of storage

and for Emulex:

http://www.emulex.com/ts/index.html

or if You have access to powerlink.emc.com - try to look on their
knowledge base.

But generaly will be very hard to compare one value for various HBA's
and storage. I think, that You should check proposals for all and
compare if they are not totally different :-)

Regards,
Blazej Antczak

Stuart napisal(a):

Hi all,

quick question - working on a automated solaris 10 build for our
customers, and they support a number of different HBA's and Storage
arrays - I wonder if anyone has come across a good reference point for
suggested Kernel Tunables for storage within solaris

for some of detail - HBA's are a mix of the usual suspects from Emulex
and Qlogic
Storage arrays are (again) usual suspects from EMC / HDS etc.

any words of wisdom would be greatfully recieved.

Many thanks,

Stuart

I believe that there is
a convention that "normal" UIDs start at 100 but AFAIK it is not required.

You should really skip the first 100 UIDs. Although not all of them are
used currently you may run into trouble in the future when more and more
"system users" are introduced:

With sendmail 8.12ff you got user smmsp (uid 25)
With JDS you got user gdm (uid 50)
With Solaris 10 you got user webservd (uid 80)
etc.

The useradd program manpage explicitly warn against using UIDs < 100:

(UIDs from 0-99 are reserved for possible use in future
applications.)

Some systems allocate user accounts starting at UID 500. Linux
typically does this, although the "useradd" man page doesn't mention
this; it does say that "Values between 0 and 99 are typically reserved
for system accounts." I think what's going on here is that the system
installation routine, which prompts you for the name of the first user
account, explicitly sets its UID to 500; thereafter, other accounts
will start at 501.

If you want users to have consistent UIDs across different types of
systems (useful if you use NFS), you might consider assigning UIDs for
user accounts starting at 500. On the other hand, if you explicitly
assign UIDs, starting at 100 seems to work, at least across Solaris,
Linux, and a few other Unix-like OSs.

The in.mpathd daemon sends the ICMP echo request probes to on-link
routers. If no routers are available, it sends the probes to
neighboring hosts. Thus, for network failure detection and repair,
there must be at least one neighbor on each link that responds to ICMP
echo request probes.

In our topology there are 2 cisco routers with vrrp gateways (one is
not the default gateway).

And we need mpathd to base its up/down status on these, but how does
mpathd know these are gateways? Since it looks like it just chooses any
ip on the network to ping to?

If there is a default router, it will use that as the one and only test
target.

If there is no default router it will use multicast to find up to 5 other
hosts (not routers[1]) on the network, and use them as test target.
Under Solaris 8 and (currently) 9 this can cause issues as if all of the
test hosts go away then it will fail the link and not attempt to find any
new test target.

Under Solaris 10 (and 9, once we get the backport out - hopefully in a
month or so) it will add and remove hosts from it's list on the fly
as they go away/appear.

[1] - it uses a multicast "all hosts" broadcast to find targets. Some
routers will respond to this multicast, some will not.

Solaris currently tracks ID numbers on the IRE cache entries for a
peer. This means that, for a given remote address, the numbers used
will normally increase linearly (sequentially). The exception is when
the IRE cache entry gets flushed, which happens either when it hasn't
been used in a while (no traffic to that peer) or when there's a
kernel forwarding table (routing) change that forces cache entries to
be recomputed.

I am looking to create a project on Solaris 10 for a database server like

everyone else does.

I found a real simple how-to here:

http://forum.sun.com/jive/thread.jspa?threadID=74218
Briefly the author states to create the project like this:

# projadd -U oracle -K "project.max-shm-memory=(priv,2048MB,deny)"

user.oracle

He also states that "- because the name was of the form "user.username" it

becomes the oracle user's default project."

Where is this documented about the user.<name> and default projects? I cannot

find any references to a default project for a user in the projadd(1M),

projmod(1M) or in the "System Administration Guide: Solaris

Containers-Resource Management and Solaris Zones (817-1592-10)" manual where

it walks you through projects.

All I can find concerning a dot in the project name is that "the period is

reserved for projects with special meaning to the operating system".

Hmmm. Should one be creating projects of the form user.<name>??

How is this project he creates different from creating the project as below:

# projadd -U oracle -K "project.max-shm-memory=(priv,2048MB,deny)" projoracle

????

As I understand it, in the first case, when the user "oracle" logs in, the

oracle project is in effect (since it is their default)? After logging in

they can start their oracle database server up.

And in the second projadd example, when the user oracle logs in, would they

have to issue the command (?) below:

$ newtask -v -p oracleproj

to get or inherit the oracleproj resource settings and then be able to start

their oracle database server up? Yes/No ???

TIA

Exactly. Check it with 'id -p'.

To read about user.X look at: 'man -s 4 project' 'man getdefaultproj'.

With Solaris 10 you could run dtrace. Even though you might not want to
run it in production, if you could have a test box with similar load it
might be instructive.

For Solaris 8, you're limited to kernel I/O tracing. You can use 'prex'
to trace for a period of time, then the 'tnf' utilities to dump the
output into a file. A quick perl script can then find the heaviest I/O
via PID. Not quick and easy, but very possible.

I don't know specifically, but I belive it is an encoding of the minor

'1', '87', or '343', and '195' would be my best guess.

If you don't have too many, you can go discovering. Use a particular
process to write somewhere. Then trace and look for I/O by that PID.

The server has 6 CPU but the tnfdump output show 9 under CPU column. Any
pointer?

CPUs are not always numbered sequentially. Compare with the output of
'psrinfo'.

Hi,

can anybody post a kstat output of a multicore machine running Solaris

with cpu/sys/instance. intrstat, cpustat, and cpuinfo look consistent,
but I really would like to know for sure.

A complete output would be rather large, but basically:

module = cpu
instance = processor_id
name = intrstat/sys/vm

% kstat -m cpu | grep -v '^ '
module: cpu instance: 0
name: intrstat class: misc

module: cpu instance: 0
name: sys class: misc

module: cpu instance: 0
name: vm class: misc

module: cpu instance: 1
name: intrstat class: misc

module: cpu instance: 1
name: sys class: misc

module: cpu instance: 1
name: vm class: misc

For "kstat -m cpu -n sys" exist a second structure with almost the same
content. It is just named differently:

module = cpu_stat
instance = processor_id
name = cpu_stat%d (%d = processor_id)

% kstat -m cpu_stat|grep -v '^ '
module: cpu_stat instance: 0
name: cpu_stat0 class: misc

module: cpu_stat instance: 1
name: cpu_stat1 class: misc

Unfortunately the instances of cpu_stat are not enumerated sequentally
on multicore cpus which makes collecting the information a bit tricky,
when one consideres that a cpu could be turned off during this process.

Does anybody know, if there is an upper limit of instances. kstat_lookup
takes an int, which is a pretty long way to go, if a cpu got turned off.

Just iterate through all cpu_stat%d entries. Or call
sysconf(_SC_CPUID_MAX)
to know up to which instance number you have to iterate. Remember there
may be holes in the processor numbering, esp. on SPARC.

Any ideas or pointers?

TIA,

I mixed it up a little bit. The information of sys/sysinfo.h's
cpu_stats_t is included in the kstat output, but the structure is only
defined in Solaris 10. Solaris 9' sys/sysinfo.h misses this structure,
but the information must be there, because kstat can show it.

Any idea how to get it?

TIA,

cpu_stats are new in Solaris 10. It is basically the same as cpu_stat, but
the values are 64 bits wide instead of 32 bits. The user/sys/wait/idle
times are also converted from clock ticks to nanoseconds.

hi, i know something about this but i'm confused on a couple of points

1) where is the global list of services available to me?

2) how do i know which services are managed by this and which by the
old /etc/init.d mechanism?
eg: apache seems to be controlled by the old way, but when i try to
enable it i get the message "svcs" Pattern 'enable' doesn't match any
instances

also, when i tried the command you mentioned "svcadm enable
/network/dns/server:default" and i run "svcs | grep dns" it just comes
back with:

online 13:37:03 svc:/network/dns/client:default
offline 14:16:00 svc:/network/dns/server:default

i can't get the dns server to enable at all, maybe this isn't properly
setup (i copied over all my named and zone files from my solaris 8
machine). is there a way to tell?

thx for your help!

i think i figured it out..

to start the dns server i was trying svcadm -restart and svcadm -start
but these had no effect.

i tried svcadm disable and then svcadm enable and it came up
successfully

so svcadm doesn't behave the same as the old init.d scripts..

anyways, thx very much for your help!!

Solaris 10:

If you want to count number of processes in the Interactive class
casued by interactively logged on users.

ps -elc | grep IA | wc -l

Default number of user procs is 29.995
youll need a 100 MB Ram per user
each JDS user will run an average of 35 processes

29995/35 = 857 users *100 MB = 86 GB Ram

therefore the smallest machine where this can become a concern
is a SunFire 2900 with 12 ultrasparc IV CPU and 96 GB ram.

I'm getting tired to write commands like "ps -ef | more" or "ls -ltr".
(Yes, I know I can specify aliases).

SUN Solaris 8 with SUN Keyboard
SUN Ultra 5

There is when you're using bash or tcsh.

To map F6 to "ps -ef" in tcsh, use the bindkey built-in:

$ bindkey -c ^[[17~ "ps -ef"

To enter the F6 key sequence, press "control-v F6". Obviously,
this can be placed in your start-up file (.cshrc).

In bash, the same is achieved through the "bind" built-in. Use "read"
to find the key sequence emitted by F6

$ read
^[[17~

The ^[ is the ESC character, which in bash is represented by
\e (backslash e), so to map F6 onto "ps -ef" you'd type:

$ bind '"\e[17~": "ps -ef^M"'

(Press "control-v control-m" to enter the Return.)

On start-up, bash reads the ~/.inputrc file to map keys or character
sequences to shell commands.

Take care,

Surely it would be Ok to leave it on internal disk? Maybe move swap to the
RAID ..

This should be easy, a 'real' RAID controller is considerably less than

more software licenses or additional server hardware. Be sure to get a
RAID controller with a *battery backed* cache!

Right, but my dilema is not to persuade them to buy the RAID controller
instead of the cpus and licences, it's to persuade them to buy the RAID
controller rather than do nothing! Hence my need to try to qauntify the
likely benefit of doing so.

A very apt subject. Anyone recognizing their question for what it is
like that deserves help :), so at the risk of helping a competitor,
doesn't Sun include CPU profiling tools with the OS? I would think
that with a little luck, you could take a profile of the kernel and
see how much CPU was being consumed by SW RAID routines. You then make
the broad handwaving ass-u-me-ption that a HW RAID controller would
make all of that go poof. And perhaps a little bit more since the
multiple I/Os to the JBODs for RAID writes would also go poof,
becoming "hidden" behind the HW RAID controller.

I have doubts about this. ISTR, that you said that CPU was maxed out. Unless

the system is devoting CPU time to Software RAID; e.g. SVM or Veritas,

hardware RAID is unlikely do do a thing for you! If you, in fact, relieve an

IO bottleneck with hardware RAID, you'll just be throwing more load on the

CPU and/or memory.

Additional CPUs are not guaranteed to help either. If the application is not

such that it can run in multiple processes, or it can't use threads,

additional CPUs won't be much help.

How long is a piece of string? Twice the distance from the middle to either

end!!

BTW, didn't the customer also by the cheapest machine they thought would do

the job? IMHO, when you buy a new machine it should have sufficient capacity

to handle at least three years of anticpated growth. When you outgrow it, it

becomes your test and development system and you buy a new box for

production.

Well, the theory is that significant processing time IS being spent on
Solaris Volume Manager. But I'm trying to get a feel - from Sun, from this
peer group, anywhere really - on a typical amount.

I'm not sure I buy the second part of your argument. Funnily enough it's a
paraphrase of what the customer said: "I'd be disappointed if we don't see
at least 10% idle time at peak". What you say of course is true as far as
you go - the cpus may take up the slakc to their limit with other types of
activity - but overall you'd expect the peaks to fewer and shorter.

BTW, didn't the customer also by the cheapest machine they thought would

They bought the box, then adequate, last summer but didn't anticipate the
growth!

All true but the output of svcs -a does not tell you which service is
the removable media service.

If SUN chose a self descriptive name that would not matter.

If all you have is "smserver" you would probably not guess removable
media. I would guess sado/maso porn server. ( Not that I am into that
).

I suppose I will just write a little shell script that generates a list
of all the services, does a svcs -l on each one and picks out the
english description. That will have the same net effect.

Hi, I have read some/most of the USB/firewire posts and and based on
the experiences of others, decided to give it a shot. I needed alot
more storage and SCSI storage was kinda out of the question basewd on
the amount of storage needed.
The Solaris experience wasn't as clean as that of the MAC, but I am
glad to say that this stuff does work. The USB interface works better
than does the firewire. At least for me it does.

I think thats the case for everyone.

The good:
- It works. I increased the strorage capacity of my Ultra 60 for alot
cheaper than purchasing equivalent sized SCSI drives. Speed is not an
issue for what I plan on storing on the drives. The USB drives are for
long term backup of lots of data. Will eventually go with 500gb drives
once the prices on those drives come down a bit.
- Can now swap in and out drives as need be without rebooting.
The bad::
- Using the USB interface, I can't have the unit powered on when
Soalris is booting. When I do, a message appears that says soemthing to
the effect that it can't connect to the device sitting at the other end
of the USB interface. After Solaris comes up, I can then turn the unit
on and it will see the drives. Both of them.

That could be your "tower"s busted firmware? I built up a Promise tower
last year (non USB admittedly) - had to turn off all RAID on it and
set the powerup state to "JBOD" - then used smc to configure it.
Even then the "LUNS" were restricted to 400 GB
So 2 were made instead of 1. Been in production for about a year now.

My direct attached stand alone USB drive has to be turned on first or
I cant mount it as a regular disk..

vfstab entry:
/dev/dsk/c3t0d0s0 /dev/rdsk/c3t0d0s0 /ion_160 ufs
1 yes -

- I can't have vold running. When vold is running, I can't see the
drives at all.

Again it could be broken firmware. I have vold running no problem

- Can't use the firewire interface. When I do, I can only see 1 of the
drives. Driver problem?

Maybe. I doubt its worth the bother to get FW going if USB works OK.

- When using the firewire interface, when I reboot Solaris and the unit
is powered on, I get a kernel panic. So I'm sticking with USB for now.

Thats expected behaviour on Solaris 10. Only 1 device is supported I
believe and thats a camera.. : > Im surprised it doesnt panic ANY time
you turn it on. but then Im using a Blade 1000/2000.

Maybe the next release of Solaris will correct the problem? If I wanted
to use the firewire interface, then I have to power the unit on after
Soalris has been booted.

You can try Nevada (Solaris 11) drivers - they worked for me.

yes, that's OK. But the printed line is generated by the executable
a.out, which doesn't fork at all...

You don't understand; "a.out" may not fork() but the way the
pipe line is constructed the shell fork()s and then runs a.out
*in the parent*.

Like this:

if (fork() == 0) { /* Ok, start building pipe - child of shell */

pipe();
switch (fork()) {
case: 0 /* Child */
/* setup pipe */
/* run the first process in the pipeline */
exec(...)
_exit(1);
default: /* Parent */
/* setup pipe */
/* run the second process in the pipeline */
exec("a.out");
_exit(1);
case -1: perror("fork");
}
}

So the shell forks in the subprocess to build the pipeline; and then
uses that subprocess to execute the last process in the pipe (a.out).
That last process then has the other process as child.

sh -> a.out -> other process

and not what you might expect:

sh -> other process
-> a.out

You don't understand; "a.out" may not fork() but the way the

*in the parent*.

I did understand what you mean. I just wanted to point out that this
kind of behavior is a little bit surprising, as a.out shouldn't need to
be aware of the context it is living in. But that seems to be an invalid
assumption on my part. As I pointed out in my other posts, /bin/sh seems
to be the only one surprising its children with this odd kind of
implementation. I agree, you save on fork. But I really care about the
unexpected gift of getting a pid from calling wait, when I wouldn't
expect it to return something else than -1.

BTW: I just x-checked /usr/xpg4/bin/sh: it returns -1. In contrast,
OSF1's /bin/sh behaves the same way as the one of Solaris.

Thanks anyway for your clarification. I guess I will have to go and
review some code concerning this issue...

Cheers,
Tom

Am I missing something obvious? I thought a.out doesn't fork, so it
should never be get something else than -1 from wait.

The shell constructs a pipeline such that the last process is the
parent of all other processes in the pipe.

Solaris' /bin/sh is different to ksh, bash, and zsh in this respect.
This is really confusing. Do I guess correctly that this is one of the
/bin/sh oddities that some people might rely on and that cannot be
changed because of backward compatibility guarantees?

Thanks,
