I've tried to visit a few of these, and it seems like that either ssh doesn't work, or I just can't figure out what am I supposed to do. Telnet connections are perfectly fine, but if I try to enter with ssh followed by the domain of the bbs, then it just tries to log in as my Linux user. And I can't figure out if I need to add a flag to ssh or an user before the domain or something else.
