Hi All

I am using Red Hat Linux release 9 (Shrike) with IBM x346 Servers .
When I do telnet to Server form another VLAN , It will gives an error meassage "do_ypcall: clnt_call: RPC: Timed out" and take very long time to display the login prompt.but with in same/local VLAN its works fine.

Here is some details about our step :-

- We are using NIS,NFS and Automounter services.
Linux Server as NIS client and NIS Master/slave server are running
on Solaris 8.

- We have disabled IPTable/firewall etc.

Pls suggest, if any body have any tips, about the same ..

Thanks & Regards
Mahesh

Mahesh,

Are you running nscd (name service cache daemon)? If not, start this daemon.

You should start this daemon if you use slow naming services like NIS, NIS+, LDAP or hesiod.

Hi Denis

Thanks ,

After starting nscd , error meassage "do_ypcall: clnt_call: RPC: Timed out" is not appearing, But still it is taking very long time to display the login prompt
As we are using <file nis dns> lookup order for <hosts>

Any tip ?????????????????

Regards
Mahesh

Hi Mahesh,

We are using <files dns> lookup order for <hosts>.

I believe that the delay is introduced by the communication between the two VLANs and that you will have to live with that.

I got rid of waiting time with ssh with
UseDNS no
in /etc/ssh/sshd_config.
