SSH access problem on Powerconnect 5424
Here is the description:-
HW: Powerconnect 5424 with the following version
SW version 1.0.0.31 ( date 31-Oct-2007 time 10:32:13 )
Boot version 1.0.0.6 ( date 09-Oct-2007 time 14:09:52 )
HW version 00.00.02
Problem:
when using SSH access to the switch, the credentials are asked for twice. Eg. when using putty, first the user gets prompted for "login as:". Just hitting enter would prompt for the "User Name:" This is causing problems writing a script for auto login.
SSH clients used: Teraterm and Putty
Configuration:-
Created username with password and privilege level 15.
Generated rsa keys
Started ssh server.
Options tried:-
1. Under line ssh, tried configuring "login authentication default". No change of behavior.
2. Under privileged mode, tried configuring "ip ssh pubkey-auth". No change of behavior.

What you're seeing is your SSH client asking for login name the first time; usually the ssh client negotiates the username with the ssh server (in this case the PowerConnect). But the PowerConnect ignores the username that was supplied in negotiation, and asks for the username after the ssh connection goes up. The first username doesn't really matter.
Long story short, Dell has a cheezy ssh daemon; it may have been kludge'd onto a telnet daemon in order to add ssh support at the last minute.

It is working the way Dell thinks it should work :) . So no, there is nothing you need to do to "fix" it, other than to tweak your scripts to give the username twice.

Are you trying to script Putty? I use tcl/expect under Unix.

But let's not even bother about that. I am just wondering why does the ssh server ask for the credentials twice?

So what I am experiencing is the way the ssh connection is supposed to work?
