How to enable ssh on HP 6125G switch

ln1 — Tue, 22 Apr 2014 14:58:02 GMT

HI,

I'm trying to enable ssh and use it uinstead of telnet to access HP 6125G blade switch.

Here's my configuration:

local-user admin
password cipher $c$....
authorization-attribute level 3
service-type ssh telnet
service-type web
...

ssh server enable
ssh user admin service-type all authentication-type password
...

Every ssh attempt ends up with following:

ssh_exchange_identification: Connection closed by remote host

What's wrong with my configuration?

check this PDF file, I think it can help you:

I know this document, I followed all mandatory (non "Optional") steps from "Configuring the SSH server on the device" procedure. Still the same: "ssh_exchange_identification: Connection closed by remote host".

Can you invoke ssh with -vvv?

Note that SSH clients works perfectly with other ssh hosts. Only that switch is problematic.

The same happens when I'm trying to enfoirce password authentication with ssh -vvv -o "PubkeyAuthentication no".

I'm not sure if this is important. Is this a RSA key?

>ssh_exchange_identification: Connection closed by remote host

It seems the server just disconnects before anything can be sent.

This key is accepted by another Linux machines, I assume it's OK. Also, when I'm trying to connect via ssh from the switch itself, it's interrupted immediately.

Definitely somethin's wrong with ssh server configuration on the blade switch.

Is anybody using it on 6125G?

don't forget to generate the dsa key on the switch, and the vty access:

[switch] public-key local create dsa

[switch] user-interface vty 0
[switch-ui-vty0] ]authentication-mode scheme
