See rhosts(5). It also doesn't like to work with firewalls. ie; It doesn't seem to have an option to just act like telnet and not try to login. Telnet also has problem with some chars and simply won't pass them. One such is CTRL-O. My editor uses this to open another window, but it doesn't get passed by telnet. Rlogin has no problem with it. The -8 flag in telnet doesn't help. There is much more to them. -Different ports, different protocals, etc. But not much. -Byron byron@omix.com
