Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I am trying to follow the instructions on this site for configuring an MPICH cluster on Ubuntu: https://help.ubuntu.com/community/MpichCluster.

I am new to this and have a very trivial question. In step two the instructions say "NFS allows us to create a folder on the master node and have it synced on all the other nodes. This folder can be used to store programs. To Install NFS just run this in the master node's terminal:"

I don't know how to switch into the master node's terminal so that I see a command prompt like "user@ub0" so I can install on that node.

Update: I tried ssh user@ub0, but the terminal just stalls and doesn't do anything (it would usually say connection timed out, but I'm not even getting that...) do you know what would cause that?

You need to log into ub0 by using ssh. Do this in your terminal:

ssh user@ub0

Or simply ssh ub0 if you are logged as user on your local machine.

thanks- I tried that, but the terminal just stalls and doesn't do anything (it would usually say connection timed out, but I'm not even getting that...) do you know what would cause that? –  user99352 Oct 29 '11 at 17:23
    
@ellie What do you see when you do ssh -v user@ub0? Does it stall at something like debug1: Connecting to ub0 [xxx.xxx.xxx.xxx] port 22? If that happens, you may not have an ssh server running on ub0. –  David Alber Oct 29 '11 at 18:16
    
yes, that is where it stalls. but i have openssh-server installed, and I am able to ssh into localhost without any issues. –  user99352 Oct 30 '11 at 2:11
