Re: [MLUG] run a single command across multiple servers from one shell?

[Rick <EMAIL:PROTECTED>]

I just use ssh in a loop:

#!/bin/bash
for i in <ip addresses>
 do
  echo ">>>>> Server: $i <<<<< Executing: $@ >>>>>"
  ssh -p 2200 <user>@$i "$@"
 done

# replace "ssh" with "ssh -p 2200" for connection to sshd_secure

sshd_secure is a second SSH daemon (not available to the outside) 
running on a different port and managed by init
