check_by_ssh from a different username

[Matt Simmons]

Yes. And you can simplify this by running ssh-copy-id as the Nagios user:

--
nagios at monServ:~$ ssh-copy-id remUser at remHost
remUser at remHost's password:
Now try logging into the machine, with "ssh 'root at webdb1.int.ia'", and check in:

  .ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

Most Linux systems that I've seen provide this script. Other Unices
may not have it. If it's there, it makes it much faster than manually
copying and pasting public keys.
