There are many SSH clients. If you're running Windows, get PuTTY . For Windows sftp (interactive, command line, secure ftp - RECOMMENDED), get psftp. For Windows scp, get pscp. Or just go to the PuTTY website.
If you're on a Mac running OSX, it has OpenSSH built in. Open up Terminal.app (Applications -> Utilities -> Terminal) and run ssh from the command line. If you're running 9.x or lower, get NiftyTelnet SSH.
If you're on a UNIX-like machine, you probably already have OpenSSH. If not, grab the source for the most recent version and compile it.
