• Linux Telnet Server...

    From Shurato@21:2/148 to All on Tue Jul 9 01:56:00 2024
    How would I have a linux telnet server allow authentication from another app (my BBS) without it requiring a logon? I've got linux instructions for ele, but the telnet service requires a seperate login before accessing the system.

    There have been extensions that have done this in the past.
    The MIT Kerberos distribution used to ship with modified telnet
    client and server programs that would do krb auth instead of
    manual username/password entry. Those are long gone, though.
    RFC 1409 specifies an authentication extension (likely used by
    kerberized telnet, now that I think about it...), and there was
    another extension to provide auth via DSA certificates.

    None of those are what you're looking for though, I expect.
    The BSD telnet client has a `-a` option to negotiating
    "autologin"; I suspect it uses something like the BSD rcmd
    stuff used by rlogin etc. It's not clear from looking at
    the source code whether it's even still supported in any
    meaningful way.

    You're probably better off trying to set up rlogin or some
    kind of ssh wrapper, instead.

    I was able to use mystic and then start the bbs software, so that worked
    pretty well.
