UNIX for Dummies Questions & Answers

Hi Friends,

I have 1 NIS and 2 NFS, at every one time, the max number of user logged in is less than 60.

Everytime, I need to use the NIS. The system stops responding for around 10mins and back to normal and again stops responding again and back to normal.

Does anyone knows what is cause of this problem?

thanks
jennifer

For me, it sounds like netwrok problem.
check your machine and router/switch set up

i.e.
your machine set up for 10M-half-duplex and router (or switch) side is set up for 100M-full-duplex. This may cause machine up and down when it is trying to talk to NIS/NFS servers.

command "ndd" can help you.
do not forget to check /etc/system, sometimes, unix admin. will set up interface link mode on this file.

Hope this help.

If you know how to analise Sniffer output, try using one in your NIS network interface card. Maybe you can see if you have too many bad requests, or NFS failures. If you use solaris box, there's a sniffer called snoop. It can be helpfull.
