CDE login problem

[Pete Randall]

Walter,

Just to eliminate duplex mismatch from the problem (and you should probably do this anyway), set your NIC to 100FD and do the same on the port on the switch it's connected to. Duplex mismatches are a common source of problems and the standard recommendation is to force both ends of the connection to 100FD.

Hi Pete,

I have assured the switch/NIC issue both are forced to 100 Full duplex. Still the problem remains.

Hi Walter,

I'm not really sure how to decode that last attachment properly, so I'll leave that to Alex and continue on the networking side of things I think.

If this is strictly a performance issue (no need to patch etc) then it can be quite a long process to determine the cause. I think the best idea is if I give you a link to a document written by one of the guys at HP labs:

http://www.docs.hp.com/hpux/onlinedocs/1435/NFSPerformanceTuninginHP-UX11.0and11iSystems.pdf

As you will see it is quite in depth but very good.

The basic networking looks ok. The only other things that I would think could cause that king of delay with regards to networking would be:

1) name resolution

If you could perorm the following commands on the client system as one of the users having problems, not root.

# hostname
# timex nsquery hosts

2) Patching

The ONC/NFS performance patches have several fixes in regardings to hangs, including hangs in autofs. Useful commands to try and find if this is the issue:

Client:

# nfsstat -c
# nfsstat -m
# swlist -l fileset -a state | grep -i nfs

Server:

# nfsstat -s
# cat /etc/auto_master

If possible can you paste some of this output?

Regards,

James.

Thanks for the help James,

Please take a look at the outputs file and let me know if you ind something.
Other than the 7 bad calls from the server side I couldn't find anything wrong.
I'm not sure if this reported bad calls are important for the problem !?

Hi Walter,

Very strange. It appears PHNE_24909 was installed but only one fileset was applied to the system. Can you double check the system you took the Ignite image from to see if it is configured similarly?

This patch has warnings against it too and several special instructions to enable fixes. As most of the filesets are from PHNE_15638 you are basically running with NFS/ONC code from mid 1998.

I would advise you uninstall PHNE_24909 and install PHNE_26387. If you decide to do this, please read the patch text carefully especially the special instructions. Let me know and I can take a look at them if you need a second opinion on any of the fixes not enabled by default.

Regards,

James.
