remote ssh commands

[Nadim Hoque]

Sean,

Well when I just run the 'yum update -y' it runs it just fine but the &&
poweroff runs on the local machine. Also I have another script that does
the following:
#!/bin/bash

for server in $(cat serverlist.txt); do
       ssh  $server.localdomain 'poweroff'
done


and also running that just powers off the host. It seems that it will
execute all except the poweroff command on remote servers
