I am running 7.10 on a server and using NIS to deal with logins. My student workstations are up to 8.04.1. I use NFS to mount /home for users and DHCP for IP's. Lately, for no aparent reason (at least that I can figure out), the students are logged in and suddenly they can do nothing and their workstations freeze and neet to be hard booted. After the restart, they can not even log in. I am guessing something is going on with NIS? I tried to restart NIS on both the server and client and still nothing. I end up restarting the sever and when it comes back up, dhcpd3-server will not start until I disable the internal interface and re-enable it. After doing this, the students are able to log in and work again.

Re: NIS HELP Please....
nobody's picking this one up, so...
i don't have experience with a configuration like yours with ubuntu systems.
i can only try and give you some general hints to debug the issue.
i'll probably state the obvious, nonetheless...
all the clients showing the same behaviour (all at the same time you said?)
would point to a problem on the server.
but all the clients "freezing" hints at a more general network issue, rather
than simply nis.
you could start by configuring one of the clients not use nis and see how
it reacts. if you do this for 1 user on 1 client machine, then it's just a line
in passwd and few others, right?
then i would move its home directory local to the client and avoid the nfs
mount.
btw, do you use hard nfs mounts or soft nfs mounts?
wouldn't know what else to suggest except a systematic approach to try
and pinpoint the failing subsystem...

Re: NIS HELP Please....
Thank you for the reply. I appreciate the help.
OK, I do have a local account on all the computers (local admin account) and when I log in with that everything works, including networking (ping, http...)
I am not sure what you mean by hard/soft nft mounting, I have a line that mounts the server /home at boot.
In my troubleshooting I have already done, I noticed that eth0 starts up and the server can see the local network ( i can ping the workstations ) but the workstations can not log in to the server. I noticed that dhcp3-server did not start (no interface to listen on) and I can not start it manually until I disable eth0 and re-enable it (weird I know). I suspect that eth0 might be failing, but I do not have another nic at the moment. I am wondering if this symptom has something to do with the random failing of nis (I think nis) during the day. I do not know what logs to inspect to check? When this behavior happens, the students try to log in, the login screen dissapears and it looks like it is going to log in but just hangs there at the background to the login. This suggests that the nis lookup might be successful? If so, what else here would be failing? I was thinking maybe nfs?
Thanks.

Re: NIS HELP Please....
#1 make sure the network is ok.
take a client's nic and put it in the server.
test basic services.
ping, ssh...to and from.
then test your environment with nis, nfs, etc...
if everything's ok, then it's the nic.
otherwise swap it back and start test one subsystem at a time.
the local admin user (i assume root) will go to /root, right?
so it won't use nfs.
so you can't rule it out and you still don't know if it's nis or nfs.
that's not good.
you'll have to isolate things and test them one at a time.
that's why i suggested to reconfigure a normal user.
so that it won't use nis, but will still use nfs.
and log clients in from a tty instead from kdm/gdm/xdm whatever...
hard vs soft nfs mounts (you'll find plenty by googleing)...
basically...
hard mounts (default) will countinue to wait for the server forever.
soft mounts will stop trying after a given timeout.
after checking the nis thing i would then check nfs.
move a user's home to the local machine.
leave the nfs config, but soft rather then hard.
if it logs in, check if home dir is nfs o local.

Re: NIS HELP Please....
Thank you for the tips... I took your advice and ....
OK, 2 days with no problems and then it happened...
So, when the Students froze... I tried the following...
From my computer (no nis no nfs) - ssh to server (fine) (network is OK)
SSH from server to student workstations (fine)
From student workstation - ls /home (showed all nfs mounted folders fine) (NFS is OK)
From student workstation - ypcat passwd (fine) (NIS is OK)
From student workstation - ping google.com (fine) (DNS is OK)
I logged into the student workstation using an account on workstation (local) that has its home on server via nfs. That worked fine.
What else might I be missing? I feel like there really is no problem and all is fine (yea right).

Re: NIS HELP Please....
very good!
though, not really 100% sure about...
this might really only show the local mount points, right?Originally posted by knichel
df or mount will show the fs mount table.
or ls /home/some_actual_user_home will show the files inside...
so...
students workstations freeze all at the same time, but:
- ctrl-alt-fx works
- log in via tty is successful
- and the workstation appears to be working properly (from command line)
is all of the above correct?
disk space, for example.Originally posted by knichel
i know it sounds silly but a lot of stupid issues are due to that...
so:
- make sure you have enough disk space on clients and server both before and after log in
- clean the apt cache (apt-get clean autoclean)
- check /tmp and /var in particular (if they aren't on separate partitions, then check /)
- check where the browsers' caches are configured to write to (home dirs?)
- ...
stuff like that.
questions (unfortunately it is not easy from here):
- workstations are 8.04, you said: kubuntu?
- if yes, do you use the kde network manager?
- any funny messages in /var/log/messages (workstations and/or server)?
- could it be it's not a functional issue, but a performance issue instead?
suggestions (i still think it's something on the server but...):
- start top on tty1 (clients and server) to check cpu and mem usage
- start while true; do uptime; sleep 5; done on tty2 (clients and server) to log avg loads
- use ps on both clients and server to look for zombie processes
then start differentiating your clients (one change on one client at a time):
- configure one with gnome ubuntu
- on another one disable the network manager and stop kde-network-manager
(put the net config statically in /etc/network/interface)
- ...
aiming to isolate the failing bit...hopefully.

Re: NIS HELP Please....
yeah.Originally posted by knichel
as i said, everything still points to some issue on the server.
the probability of a piece of software (rubbish as it may be)
to go bust always at the same time always on all your clients
simultaneously is still pretty remote...
not that i'm helping much, am i?Originally posted by knichel
though, i will want to know what it is eventually.
alright?

Re: NIS HELP Please....

I forgot to check ps for zombie processes.
I was able to surf the net from my laptop, but none of the student workstations were working. I am thinking that this suggests a problem with NIS or NFS since the student workstations rely on it.
Does this output suggest anything to you?Comment

Re: NIS HELP Please....
the avg loads simply say that (i assume your server has 1 cpu)
your server is completely (1.0 avg load / 1 cpu = 100%) busy doing something...
so, obviously, it won't be able to serve any clients requests...of any type.
it would be interesting to find out what it is busy doing.
you could use top for that.
and ps maybe.

I will try ps next time. How do I check for Zombie processes?

Re: NIS HELP Please....
yeah...funny!Originally posted by knichel
you're sure there's no messages in the system logs that could hint at the issue?
i have ps aliased to ps -eo pid,ppid,state,start,euid,euser,tty,argsOriginally posted by knichel
the 3rd column is the process state.
S is sleeping, R is running, ..., Z is zombies.
you could enter something like:
you could also do something like...Code:ps -eo pid,ppid,state,start,euid,euser,tty,args | grep " Z "
start this script (put it in a file named uptime.sh, for example) when you boot your server:
and keep an eye on it with:Code:#!/bin/bash exec 1> /var/log/uptime.log 2> /dev/null while true do uptime sleep 5 done
start it before your clients start working.Code:tail -111f /var/log/uptime.log
see how the avg loads change as your clients work.
perhaps you can at least spot what triggers the problem.

Re: NIS HELP Please....
it's very difficult to say anything about those packets you see in your logs.
i would need to know exactly how your network is set up.
and it would still be very difficult.
besides, you wouldn't want to give that information away anyway.
i agree there's some funny stuff in there, though...
this, in theory, is a broadcast packet received from a private network.Originally posted by knichel
whether or not it makes sense in your config i don't know.
it is also difficult to say whether or not you can remove avahi.
you should know whether or not you use it.
if you asked, you probably don't use it...
so, i reckon you can remove it.
i don't use it, so i personally always remove it.

I tried to restart kdm-kde4 on the workstation and it did give me a login screen with the NIS users. I was able to log in with a username and password (at least it did not fail) but the screen got stuck at the "wavy vlue background" for kdm-kde4.
I checked df and nothing is more than 8% full.
The server does seem to be functioning, but also seems to have heavy loads. Anything else I can check? The workstations are dead in the water as far as the GUI is concerned.
