Is there any way I can have control of my linux console through my OS X computer?

Yes, with SSH. On your Linux machine, you'll need to install OpenSSH (if it isn't already installed) and then start the server. Distros have their own scripts for starting the SSH server, but you should be able to start it with sshd (see the sshd man page, with "man sshd"). OpenSSH also includes the client program, ssh and on your OS X machine you should be able to run "ssh user@host", replacing user and host with the relevant username and IP address for your Linux machine. Obviously you'll need to install OpenSSH on your Mac machine as well (or another SSH client).

Wow, thanks, didn't need to do anything , just types user@local and it worked

thanks very much

It's worth looking into generating keys and having some firewalls for security, so looking deeper into ssh isn't a bad idea. You can also forward X apps over ssh so you could run graphical linux apps on your Mac OSX.

As a side note if SSH was running and you didnt know, there might be other services that you can remove, may speed up your machine and close potential security holes.
