How mount the logical interface on Linux

Xuquan Lin — Wed, 06 Jul 2005 13:37:19 GMT

Hello,

I have a HP-Unix as a NFS server and a Redhat Linux as a NFS client. On the client side, I am able to execute: " mount 201.20.4.1:/tmp /tmp/test ". However, I am NOT able to execute " mount 201.20.4.11:/tmp /tmp/test". The only difference between these two commands is the ip addresses. "201.20.4.1" is a "real/ physical" ip address for a NIC in the NFS server, and the "201.20.4.11" is a logical ip of the NIC. For example, “201.20.4.1” is the ip for lan1, and “201.20.4.11” is the ip for lan1:11.

Actually, I am able to execute the following commands on the Linux client:
" telnet 201.20.4.11"
"Ping 201.20.4.11".

I do not understand why Linux system can not mount the logical interface.
Really appreciate any help.

Thanks!

Tomm

could be that NFS server on the unix machine does not run NFS service on the logical interface.

check the netstat on the HP-UX and it should state that NFS server listens on all the available ports (eg: *: LISTEN). if not configure it to listen on the logical interface also.

Try to do NFS mount from HP-UX box itself.
eg:
From HP-UX box:
mount 201.20.4.11:/tmp /tmp/test

it should mount the NFS file system, if configured properly.

Hope this helps,
Gopi

Run:

rpcinfo -p 201.20.4.11

to see if nfs is running on that interface.

You should check the name resolution on both servers, name resolution can cause nfs problems.

What is the error when you run mount 201.20.4.11:/tmp /tmp/test?
