Interpreting NIS ypserv.log

[Rosli Ahmad]

Hi,
We have NIS running in environment all this while, but lately we notice our slave machines load shot up to 100%. We then run the debug mode but have problem in interpreting the ypserv log.

We think it's the ypdb_* calls below are the culprit as these entries doesn't exist under normal circumstances.

Does anyone ever interpret the ypserv.log or aware of any reference material we can refer to?

We're practically in hot soup already.

Thanks.

Hello Rosli,

Hot soup? Sounds like a good thing? Guess not.

Try doing some logins on the slave server, direct or via su - username

See if the logs produce anything interesting.

Is there perhaps a Master NIS server offline?

Hi Peter,
No, you wouldn't want to taste this soup...

The login is fine so is the NIS master. We just don't understand why the ypdb_* keep happening.

Any good link describing NIS in details, explaining what ypdb_* is all about?

Thanks.
