That would be either
  system("ssh",variable)    # you split the args
or
  system("ssh #{variable}"  # shell splits the args

But this is probably not what you want, unless you're just using ssh to 
execute a single command remotely, and you're using RSA keys so you're 
not going to be prompted for a passwords.

Have a look at Net::SSH and Net::SSH::Telnet (the latter wraps Net::SSH 
in an API which is a drop-in replacement for Net::Telnet)
