You can use telnet command on UNIX or a telnet client on Windows (e.g. PuTTY from www.putty.org) to connect. Or, for much more comfortable experience, use one of the MUD clients. Andy's favorite is TinyFugue (commandline-based for Linux), others prefer MUSHclient, zMUD, Tintin. There is a package of MUSHClient with multitude of BrutusMUD-specific plugins compiled by Rahman here.
