I've done a number of these and the choice depends on many things but perhaps the biggest factor is;
Is server 1 and server 2 behind the same firewall or are they exposed to the internet? Behind a firewall you can probably get away with running any one of the following commands to remotely execute your script on server 2, from server 1; Rexec, rsh, rpc, just to name 3. The client part of the protocol is required on server 1 and the daemon part needs to be running on server 2. Across the open internet, be very careful here, I would think the choice would be ssh (secure shell). This has several nice features that could be useful internally as well. You start out by exchanging encryption keys between the two servers and because of this handshake, each server trusts the other in a way that the correct execution permissions can be established on server 2, and of course the data sent between the servers is encrypted rendering it virtually useless to third parties. Google for ssh for more info.

It works great when your logged into the server and running it from the CLI. I have a GUI on server 1 that is used to input user info into a database. Question: What I'd like to do is have server 1 call the script on server 2 and have server 2 return a variable back to server 1 to be displayed and ultimately entered into the database. If you understand my rambling above and have any insight into how to get this accomplished, it would be greatly appreciated. Thank you.
