Using a device number (i.e., the "6") is not portable. I think (may be
wrong??) it's a SCO'ism. You need to use the more portable form, which
works on all tars on all Unixes: tar xvf /dev/fdx where the 'x' is '0'
for drive "A:" and '1' for "B:".
But probably more importantly, if these tar archives are split across
multiple volumes I believe you will not be able to restore anything but
the first tape with GNU tar. My experience is that each tar program
uses its own (i.e., different) mechanism to describe the nature of the
split itself.
You may be able to install the iBCS2 module on your LInux and bring over
a tar from a SCO system to use. Haven't tried it myself.

Client Machine: Linux (SuSE 7.0) Pentium Class Machine

What: How to get File systems on Sun automount seamlessly on my Linux
client machine?
What have I done so far:
1. replicated /etc/nsswitch.conf from Solaris settings.
2. Copied file mounts from /etc/mnttab /etc/mtab
NIS works fine, as I can see the list of all users on my Linux client.
3. /etc/netgroup has been edited to add my machine (hostname) to the list
of trusted hosts
4. Have a local copy of /etc/auto_home and /etc/auto_master set in
Solaris machine
I am sure there is something missing from my end in getting the automount
to work. Surely there has to be 100s of Linux client machines connected to
Solaris NFS servers which has several file systems mounted on Solaris side.
So there has to be some simple way to automount the Solaris file systems
on Linux Client ??
I am looking for answers..
Thank you

Subject: rexec not working
I can't seem to get rexec to work on my RH 7.0 machine. I've changed the
configuration in the /etc/xinetd.d/rexec file to default to on and not to
disable:
# default: on
# description: Rexecd is the server for the rexec(3) routine. The server \
# provides remote execution facilities with authentication based \
# on user names and passwords.
service exec
{
socket_type = stream
wait = no
user = root
log_on_success += USERID
log_on_failure += USERID
server = /usr/sbin/in.rexecd
disable = no
}
I've commented out the lines below in my /etc/pam.d/rexec file:
# auth required /lib/security/pam_securetty.so
auth required /lib/security/pam_stack.so service=system-auth
# auth required /lib/security/pam_nologin.so
account required /lib/security/pam_stack.so service=system-auth
I can log into a unix box and rexec to my box fine, but I can't rexec out from
my box. My hostname was added to the trusted host list on the remote node, but
it still won't work. I can't even do an rexec from my box back to itself.

Hi,
Can someone tell me how gnome finds png files it requires?
Gnome on my machine has just decided to forget where they are but they
are still there.
I do not get an icon where the Gnome footprint used to be, just small
letters saying start and all the icons on the left of the text on the
pop-up start menu have gone too.
I have also lost the task manager bit showing all my open apps and any
applets on the task bar such as the clock and modem monitor tool. I'm
guessing its a path gone missing in a config file somewhere. What
config files specify paths?
When I shut down my X session I get messages such as:
Warning Cannot find pixmap file gnome-logo-icon-transparent.png and a
load of other gnome-*.png files
Also one about /home/user/.gnome/gmc-imp8Cx could not be deleted or
something similar.
Any help gratefully received!

That brought to mind that on one particular digital telephone switching

Subject: Time Flies and it is not Fun
From: [EMAIL PROTECTED] (Martin McCormick)
Date: Wed, 22 Nov 2000 17:54:07 GMT
I have built a 2.2.17 kernel for a Dell Dimension xps h266 and
as I stated in earlier messages to the group, it basically works. The
system comes up, does dhcp, and talks on the network like it should.
The first hint of trouble happens at almost exactly 10 minutes after
boot when the date suddenly shoots ahead some random amount of time.
I have had it gain about 16 hours before or it may gain as much as 42
or 43 hours. I don't think the actual amount tells us anything except
that something is writing junk to a counter.
I was telling this tale of woe to some of our local Linux
group and somebody said that there is a jiffy clock which is
deliberately set to overflow about 10 minutes after initial start so
that one can know if one's software can handle the overflow. It
sounds like something is not handling it, all right. I don't know for
sure that this is the problem, but the glitch seems to hit right at
the ten minute mark. I waited around another 10 minutes until the
uptime output said that the system was up for 20 minutes and there was
no further sudden increase. Oddly enough, the uptime counter must not
derive its value from the same place as the counter for the time and
date, or the conversion program for the local time zone must be
corrupted for the uptime value does not reflect the glitch. It keeps
indicating a value appropriate for the amount of time the system has
been what passes for up.
When I posted this message last week, I mainly asked where I
should be looking to solve a problem like this, and my question still
remains although I have found out a few more things since then.
One of the local Linux group folks I talked to said that he
had had similar problems and had gone back to an earlier kernel but
that 2.2.13 had a security problem of some kind. I certainly hope
that I am not perpetually bound to an old kernel for this otherwise
great system.
How often does the jiffy clock overflow under normal
conditions? The person who told me about it wasn't sure but thought
it was several weeks and that the kernel boot procedure simply set it
to a value that was about 10 minutes worth of ticks below the maximum
value so that one would find out what happened sooner rather than
later.:-) What is the granularity of this clock or how many times per
second does it get updated?

There is (this is hearsay) a security leak in Solaris <2.7 that can be
exploited by automounting, and so the automounter, or at least some
function of it, does not work. You'll probably need to look through
the updates on docs.sun.com. About the only thing that I've found
necessary to share any volume of a Solaris server, is to add the
shared volume entries in /etc/dfs/dfstab, and the correct uid/gid
mappings in /etc/exports and /etc/fstab for the client side for
read/write privileges, but I'm not sure if that's what you meant by
"seamlessly."

I do not want to receive the output of a cron job in my mail so I've
redirected stderr and stdout to /dev/null. However, this doesn't seem to
be working because I'm still receiving the output in my mail.
To test this, I've set up a cron job as follows:
0,12,24,36,48 * * * * ping -c 3 apache.org
For this job, I receive the following output in my mail:
PING apache.org (63.211.145.10): 56 data bytes

--- apache.org ping statistics ---
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 157.0/189.7/213.4 ms
If I change the cron job to the following:
0,12,24,36,48 * * * * ping -c 3 apache.org 2>&1 > /dev/null
I still receive the same output in my mail.
Why is the output still being sent to my mailbox?

I have found that Software RAID on Linux to be MUCH faster than non RAID. I
get almost the same speeds as Hardware RAID. Don't know much about Solaris but
it sounds like a problem with the drivers. The Software RAID drivers for linux
work very well. I have 2 IDE drives with transfer rates of 19.5mb/s and
24mb/s. In my RAID array I get 38mb/s. I do agree that a hardware solution is
a better/faster option, however Software RAID is FREE! If I can almost double
my disk I/O for free I will! I have never had a problem with Software RAID, it
has been rock solid and reliable on my home server. BTW my disk writes are
a good bit faster than a single drive, reads are MUCH faster! With RAID 1 yes
your disk writes will be a little slower, but reads should be just less than
double single drive speeds.

The lpd daemon spaws itself whenever there is work to be done. Doing a
tcpdump my daemon would send a message over the remote printer machine,
and would get answers back and then everything would hang. So I suspect
that the second daemon was spawned to handle the job and then something
