ssh client disconnected after successful login

[Azhar]

Binary package hint: openssh-client

Bug is exactly similar to the one submitted to Fedora here

https://bugzilla.redhat.com/show_bug.cgi?id=466818

[Jan (jan-redhat-bugs)]

Description of problem:
After a recent upgrade I am no longer able to log in to the embedded devices like HP ProCurve ethernet switches or APC master switches - the remote device just closes the connection after receiving the password.

Version-Release number of selected component (if applicable):
openssh-server-5.1p1-2.fc9.i386
openssh-clients-5.1p1-2.fc9.i386
openssh-askpass-5.1p1-2.fc9.i386
openssh-5.1p1-2.fc9.i386

How reproducible:
100 %

Steps to Reproduce:
1. install the above version of openssh
2. try to log in to the remote device using password

Actual results:
connection is closed by the remote side. APC master switches do not
say anything, with HP ProCurve ssh says the following:

Received disconnect from XXX: 2: protocol error: rcvd type 80

Expected results:
Command-line prompt on HP ProCurve (tested 2650, 2848, 4300), menu screen on
APC (tested version 7920).

Additional info:
Downgrading to 5.0p1-1.fc9 fixes the problem. The problem happens at least on i386 and x86_64.

I will attach the two ssh -v sessions (one with 5.0p1-1.fc9, the other one with 5.1p1-2.fc9).

Created attachment 320228
ssh -v with 5.0p1 and 5.1p1 to the APC master switch.

[Tomas (tomas-redhat-bugs)]

Do you see anything suspicious in ssh -vvv session with the 5.1p1?

[Jan (jan-redhat-bugs)]

Created attachment 320323
ssh -vvv to the APC master switch (5.0p1)

[Jan (jan-redhat-bugs)]

Created attachment 320325
ssh -vvv to the APC master switch (5.1p1)

OK, here you are. Running diff -u on the above two files did not show anything I can make sense of :-)

[Meta: is it just me, or is Bugzilla these days _awfully_ slow? Just opening the bug page took about half a minute here, the same for adding attachments and every other page]

[Fedora (fedora-redhat-bugs)]

openssh-5.1p1-3.fc9 has been submitted as an update for Fedora 9.

[Jan (jan-redhat-bugs)]

Works for me (tested x86_64 arch only, against both HP and APC boxes). Thanks for solving the problem this fast!

[Meta from the comment #4 stil holds, bugzilla is still very slow here]

[Tomas (tomas-redhat-bugs)]

Upstream solved it just today, not me :)

[Fedora (fedora-redhat-bugs)]

openssh-5.1p1-3.fc9 has been pushed to the Fedora 9 stable repository. If problems still persist, please make note of it in this bug report.

Adding these lines to /etc/ssh/sshd_config makes my daemon work properly.

        ChallengeResponseAuthentication yes
        PasswordAuthentication yes
