The correct command for telnet is:
> telnet router4.limewire.com 6346

If you don't know how to use a command-line application read the help either by adding the parameters "-h" or "--help" to the command or by entering "man [command]"(*N*X, OSX), "info [command]" (*N*X, OSX) or "help [command]" (DOS, WI***)


You can't use ssh (why did you try it anyway if you don't know what it is???)
