Hi,
Problem:
This morning, our NIS master server down (due to ram prob), and what happen is all the sun servers able to bind to NIS Slave, but not Linux servers.

Details:
sun_server[sab]% telnet linux01
Trying 10.x.x.x...
Connected to linux01.
Escape character is '^]'.
do_ypcall: clnt_call: RPC: Unable to receive; errno = No route to host
YPBINDPROC_DOMAIN: Domain not bound

linux01 (Linux release 2.6.9-55.ELsmp #1 SMP Fri Apr 20 16:36:54 EDT 2007) (4)
Once the NIS Master is up, able to login.

Where is the prob, in Sun or Linux?
In Linux, how to make it able to failover to NIS slave?

I'm still new to all these server and network config in linux, appreciate your help.

What does your NIS config look like? Are you broadcasting or do you define NIS servers to look for?

Hi Alucard,
Sorry for the late reply (due to weekends)
In the linux box, i defined the main and backup NIS servers to look for at "system-config-network" , at the DNS and host tab, is it right?

How to check my NIS config? It is broadcasted from NIS main server which is in Sun box.
