Is it possible >at all to display the IBM charset on a virtual console? The following is copied from the minicom Install file: The Linux console only maps 1-to-1 in a special mode. Therefore you need to make a special termcap entry in /etc/termcap that initializes the console on startup: mc|minicom|mc80x25|termcap entry for minicom on the console:\ :is=\E(U\E[m\E>\E[4;20l:\E[?8;25h\E[?1;5;6;7l:\ :rs=\E(B\E[m\E>\E[4;20l:\E[?7;8;25h\E[?1;5;6l:\ :bc=:as=:ae=:am=:vb=\E(B\007\E(U:\ :tc=console: To use this information instead of the normal 'console' information, minicom has to be invoked with the '-t mc' option (meaning use TERM=mc instead of the normal TERM environment variable). And, in my /etc/profile I have added the lines: if [ "$TERM" = console ] then MINICOM="-l -con -tmc" ; export MINICOM fi So when I log in on the console I can use minicom in full color full ANSI mode to call all kinds of BBS's and the like! ------------------------------ From: poe@daimi.aau.dk (Peter Orbaek) Subject: Re: Loophole in login in util-bin-2.0 Date: 2 Nov 1993 12:16:13 GMT Thus spake ceh@eng.cam.ac.uk (Charles Hawkins): >I have found a loophole in login in this package.

Date: 2 Nov 93 11:38:48 GMT I know that this question comes up again and again and I read the net.faq but it's driving me crazy that there's never a detailed description of HOW TO SETUP A LOCAL TCP ENVIRONMENT (no nameserver, no other networks, no ethernetards, di nada). I temporarily "solved" the problem by just putting my local host behind the 127.0.0.1 local entry in /etc/hosts, but meanwhile this put me into some trouble (programs needing another address than 127.0.0.1, rcmd complains about socket permission denied (even as root)) so I would like to have a proper setup. I know that with SLS 1.2 the whole setup worked perfect from the beginning. Could someone do me the favor and either post or mail me his _working_ local version of /etc/rc.net /etc/hosts etc?

I have NO .rhosts for root on the linux box, and if I TELNET onto the linux box as myself and then execute su - I AM asked for the root password. I also have no .rhosts entry for root at any machine in my account so when I rlogin in from being root I AM asked for a password. rlogind executes login to get the password and thence my uid/gid is 0 and euid is my uid. The problem was cured by going back to my old login for which I have no source.
