So did anyone actually get this to work? I've built the v5b6 telnetd
on an AIX 4.1 system with these patches, and am trying to connect
using a V4 telnet client. I'm using "telnet -ax hostname". I get
connected and can login, but if I try to run "emacs" or "stty raw"
the session hangs:
/usr/pubsw/bin/telnet -ax hostname
Trying 36.nnn.nnn.nnn...
Connected to hostname.Stanford.EDU.
Escape character is '^]'.

hostname:~ 1# emacs
(just hangs at this point)
If I send a telnet are-you-there it answers with "[YES]", so the telnetd
is still responding. I also wrote a simple script that did "a; stty raw; b"
and I've verified that "b" does run, although the session still appears
hung after the "stty raw" command is executed. I've examined all the stty
settings and they seem fine. I've also tried tracing the stty but that
didn't do much good. Any other suggestions?
Other commands work fine via the encrypted telnet (including vi, clear, etc).
I've tried using the v5b6 login.krb, our locally hacked v4 login.krb, and the
standard AIX login program (using -f...) and they all hang. Encrypted rlogin is
working great, but we really need encrypted telnet as we are using an
encrypted telnet client from a Mac.
so close, but yet so...
thanks, roland
