Any chance someone would have some code for that?
I keep saying I'll learn Linux (not a big fan of Bill) but that darm problem with the Earth's rotation staying at a measly 24 hours/day is killin me!

Ok, I've got an example, I cut out ip's and the "SendMsg" function, but
you
ought to be able to figure out where to go from here. Also it doesn't
check
tomcat via wget of a jsp, it does a rsh and checks for the process. This doesn't help if tomcat is hung up, but that hasn't been much of a problem
as
of yet.

What does everyone use to check the status of a remote server?
I am needing a script (or what have you) that will validate that my Tomcat server is up and running on timed intervals. If the server is down, I need to post to a web page that sends either (or both) an email & a msg to my cell phone (think I have this part figured out).
Anyone care to share some code? Or offer some ideas?
It would be very much appreciated! Thanks, Chris
