Description Jan "Yenya" Kasprzak 2008-10-13 16:33:20 EDT
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).

ssh -v with 5.0p1 and 5.1p1 to the APC master switch.
Comment 2 Tomas Mraz 2008-10-14 07:17:09 EDT
Do you see anything suspicious in ssh -vvv session with the 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]

Comment 6 Jan "Yenya" Kasprzak 2008-10-17 05:35:51 EDT
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]
Comment 7 Tomas Mraz 2008-10-17 06:43:57 EDT
Upstream solved it just today, not me :)
