Simple SSH client to execute remote commands?

[Jan Lemmermann]

Hey there,

I'm looking into the SSHD subproject since I need to write a small Java 
prog which
simple executes a couple of remote commands on a SSH host and greps the 
output
from these commands.
I've tried using the SshClient.setUpDefaultClient but I wonder if anyone 
has a concrete
example on how to send a shell command and work with the output.

So far I was able to connect to the SSH server successfully but I'm not 
sure how to proceed.

Thanks in advance for any help,
Jan
