Executing commands on a running server from the command line

sorry about that! yeah, I was off a bit..and I don't just mean the port

So say my server reboots every night. Is there a way to automate a system wide message that the server is coming down and people need to log off. I know I've seen this on other servers. I thought there might be commands one could execute from the command line console where the server is running, but maybe not.

Anyone know how to automate a system message before a automatic server reboot takes place?

you can automate telnet and http connections via almost any programming language. you could use perl's Net::Telnet or Expect modules to write a small script that is scheduled to fire off prior to your reboot.
