sun4 8.2.8: telnet

daemon@ATHENA.MIT.EDU (Derek Atkins)
Thu Jul 30 17:05:44 1998

To: bugs@MIT.EDU
Date: Thu, 30 Jul 1998 17:05:40 EDT
From: Derek Atkins <warlord@MIT.EDU>

System name:		sidney.mit.edu
Type and version:	SPARC/5 8.2.8 (with mkserv)
Display type:		cgsix

What were you trying to do?
	telnet (with Kerberos) to a tuzanor.pc.cs.cmu.edu

What's wrong:
	When I try to telnet from an 8.2 machine, I get an error (the
transcript is included below).  You will notice that it doesn't even
get the shared kerberos key.  Note that if I run aklog (which works),
and I get the TGT, telnet still wont work (I didn't send this in the
transcript, but I can if you want...  I get the same error and two
extra krb4 keys, the shared key and afs@CS.CMU.EDU)

What should have happened:
	I should have been able to telnet successfully.  I _CAN_
telnet successfully from the dialups using the exact same telnet
command, so this is a particularly 8.2 problem.

Please describe any relevant documentation references:
	telnet(1)
