System name: contents-vnder-pressvre.mit.edu
Type and version: SPARC/5 8.2.3 (with mkserv)
Display type: unknown
What were you trying to do?
Telnet to an 8.2 machine with encryption as a different user who is
not allowed to log in.
What's wrong:
When I press ^D at the login prompt to quit, I get garbage
characters before the connection closese
What should have happened:
Not that.
Here are some examples (I am pressing ^D at all password and login prompts):
Normal telnet:
3 contents-vnder-pressvre:nathanw>telnet xcb
...trying Athena's default telnet options: "-axf"
Trying 18.70.0.149...
Connected to X15-CRUISE-BASSELOPE.MIT.EDU (18.70.0.149).
Escape character is '^]'.
[ Kerberos V5 accepts you as ``nathanw@ATHENA.MIT.EDU'' ]
What you type is protected by encryption.
Password for nathanw:
Error while reading password for 'nathanw'
Login incorrect
login: Connection closed by foreign host.
Trying to telnet as another user (not allowed to log in):
7 contents-vnder-pressvre:nathanw>telnet -l sipb0 xcb
Trying 18.70.0.149...
Connected to X15-CRUISE-BASSELOPE.MIT.EDU (18.70.0.149).
Escape character is '^]'.
[ Kerberos V5 accepts you as ``nathanw@ATHENA.MIT.EDU'' ]
You are not allowed to log in here: You are not allowed to log into this machine remotely
Login incorrect
login: You are not allowed to log into this machine remotely
Connection closed by foreign host.
Same as above, plus Athena options:
8 contents-vnder-pressvre:nathanw>telnet -axf -l sipb0 xcb
Trying 18.70.0.149...
Connected to X15-CRUISE-BASSELOPE.MIT.EDU (18.70.0.149).
Escape character is '^]'.
[ Kerberos V5 accepts you as ``nathanw@ATHENA.MIT.EDU'' ]
You are not allowed to log in here: You are not allowed to log into this machine remotely
Login incorrect
login:k!~[!^<N><twt"=!vO<THD`Fx?`72IzIh&n.I1-FM4N~hConnection closed by foreign host.
This is where the trouble starts.
Without -f:
9 contents-vnder-pressvre:nathanw>telnet -ax -l sipb0 xcb
Trying 18.70.0.149...
Connected to X15-CRUISE-BASSELOPE.MIT.EDU (18.70.0.149).
Escape character is '^]'.
[ Kerberos V5 accepts you as ``nathanw@ATHENA.MIT.EDU'' ]

Login incorrect
login: O}"JPEV>-oF6_@R!l!p_0<CTau4/p(G#0~/:3oYY3eXP@WEConnection closed by foreign host.
Still wrong.
Without -x:
10 contents-vnder-pressvre:nathanw>telnet -a -l sipb0 xcb
Trying 18.70.0.149...
Connected to X15-CRUISE-BASSELOPE.MIT.EDU (18.70.0.149).
Escape character is '^]'.

You are not allowed to log in here: You are not allowed to log into this machine remotely
Login incorrect
login: You are not allowed to log into this machine remotely
Connection closed by foreign host.
And the problem goes away.
I see this problem trying to connect to Solaris 2.6, Irix 6.2, and Irix 6.3
machines.
