Bug#495917: openssh-client: unable to connect to Netscreen Devices with version 1:5.1p1-2
Subject: openssh-client: unable to connect to Netscreen Devices with version
1:5.1p1-2
Package: openssh-client
Version: 1:5.1p1-2
Severity: important
*** Please type your report below this line ***
yesterday my lenny told me to update ssh
from openssh-client_4.3p2-9etch2_i386.deb
to openssh-client_5.1p1-2_i386.deb
since then, I cannot connect to Netscreen Firewalls.
unfortunately I do not know the SSH implementation of thos Netscreen
firewalls - but I am sure about the following:
* ssh v2 is used
* PKA with DSA keys worked
* Password authentication worked
I can reproduce the problem:
when I downgrade to openssh-client_4.3p2-9etch2_i386.deb, everything works
when I install openssh-client_5.1p1-2_i386.deb, everything works
I have made logfiles of the cases "ok" and "ko"
with the command ssh -vv UTROR@192.168.1.2 2>&1 |tee __logfile__
and replaced my username with __MYUSER__
see the included logfiles ssh_ok_4.3p2.txt and ssh_ko_5.1p1.txt
best regards
reinhold
