SSH question, Please help

Hello Everyone,
I hope you can help me. My problem is I have to run server programs from multiple Linux machines, but I will run them remotely from one machine. That is I will run program1 on machine 1 and then by remote logging into machine 2 I will run program2 . My problem is I have to set up log in info with ssh because I will be running the second program from my first program's interface, not from the command line.
I will log into machine 2 using ssh from machine1 even before I run any programs, but once I start running program1 on machine 1 I will then run program2 on machine 2 using program1's interface, I need the remote login to go through without asking me for a password because this will affect the running of program1 otherwise.
So I know I have to invoke the system() command in my first program's code to run a command line argument invoking program 2 on machine2, but I am not sure how to set up ssh to bypass asking me for password etc. The
manual page on ssh just confused me, so I am desperate for your help.

I did not get the entire picture... but look at the remote shell command (rsh), it might come helpul in your situation.

Hey, you can setup keys with SSH so you don't need to provide a password when logging in to a system.

Check the openssh or other ssh web site for information on setting up keys.

Good luck.
