I have 2 computers: A and B.
Computer A is used to login into computer B through SSH.
Now, I would like to run a program in computer B, lets say firefox. I am already logged into computer B from computer A, so I can for example type: "mkdir aDir", or "kill 2558", and so on... all those commands work fine.
Conclusion: after a successfull login with SSH, in a console from computer A I can execute commands that take effect in computer B.
How can I start a program in computer B from computer A ???
