please suggest what to do

Also it looks like you are using an IP address for the NIS master. In that case ensure the the NIS master is resolved on the HP host. You should add the name/IP of the NIS master in /etc/hosts and have "files" before "nis" in /etc/nsswitch.conf.
Post the contents of /etc/nsswitch.conf and /etc/rc.config.d/netdaemons (the NIS stuff only). Check the contents and permissions of /etc/nsswitch.conf. It should contain nis directives for the NIS maps and be readable by everyone. Same for /etc/hosts, check NIS name/IP and permissions.

hi please fond the out put of /etc/rc.config.d/netdaemons and /etc/nsswitch.conf files output

[TTr]

Try putting "files" before "nis" for the hosts map in /etc/nsswitch.conf.
I meant to ask for the /etc/rc.config.d/namesrvs file not netdaemons.

[sreerag]

hi i made files first for hosts in nsswitch.conf file
hosts: file nis
still i am getting same error
# ypwhich
ypwhich: clnt_create error: RPC: Unknown host

i am attaching the /etc/rc.config.d/namesvrs file nis portion

[TTr]

Are the permissions for /etc/hosts and /etc/nsswitch.conf readable by all? Also is /etc readable and executable by all?
In /etc/rc.config.d/namesvrs, change the "YPBIND_OPTIONS" to YPBIND_OPTIONS="-ypset -l /var/yp/ypbind.log" and restart the NIS client service. Check the log file to see if additional errors or info gets posted there

I just remembered this thread about the similar issue

On the Linux host change the encryption type for the password.

[sreerag]

ya i have set ypset -l /var/yp/ypbind.log

option

# more /var/yp/ypbind.log
08.31 22:17:35 ph047dor pid=7654 /usr/lib/netsvc/yp/ypbind
ypbind will not use the servers list available in the file /var/yp/binding/
/ypservers for binding purpose. Also if ypbind is invoked with -bro
adcast option, then -broadcast option is ignored.
08.31 22:17:35 ph047dor pid=7655 /usr/lib/netsvc/yp/ypbind
ypbind -ypset: allowing ypset! (this is insecure)


and the link mentioned is not accessible

The problem is the Linux NIS server is using MD5 enclyption for the passwords and the HP-UX is using DES encryption. So the NIS server password can not be deciphered on the HP-UX client. You have to change the password encryption method on the Linux server to DES.

hi thanks a lot
i disabled MD5 in linux and it is taking authentication from hpux

now i am facing problem with automount it is taking long time
if i give su - it takes more time to switch user

and i mounted the filesystem directly then it is working fine please sugest

[TTr]

Automounter is not easy to troubleshoot. Is it the old automounter version or the newer autofs? It is part of NFS so keeping NFS up to date with all the patching is a good start. Also check that name resolution for all the hosts involved in this setup works fine.
Search the itrc web site for the document "NFS performance assessment" and check it out.
