just for the record, there's a much more secure way of doing this.
create an ssh public/private keypair, let's say nagios_cmd_1 and
nagios_cmd_1.pub.  create these keys without a passphrase, and then in
nagios_cmd_1.pub, prefix the key with the text:


now you have an ssh keypair which can be used in a script without requiring
any password, and it can only be used to execute the command you've
specified in the public key.  put it in the .ssh/authorized_keys file
on your destination machines.  i do something like this to check
disk, load, and swap on all my machines.
