I was able to get the SSH module working and I could connect to my other machine and check to see if Firewall daemon was running. The while loop that was in the README example worked correctly, but I would like to throw in a if..else statement, but I can't get it working.

Also, can somebody explain to me what the READER and WRITER functions do in this module?

I'm pleased that I got this far without having to post. I'm trying to holdout until I absoultely don't have a clue.

I appreciate the help.

        }

         close(WRITER);
