Ssh connect reads input from check_mk

General

I have a question; I probably misconfigured something, and need a way out.

How comes that if I ssh into a node, I get the check_mk results delivered, instead the login prompt of the server?

This is the picture. From the checkmk server I want to connect to a client:

root@sallcheckmk:[/]> ssh ip-address-of-client
<<<check_mk>>>
Version: 2.0.0p9
AgentOS: linux
Hostname: sallapprfs01.research.silicon-austria.com
AgentDirectory: /etc/check_mk
DataDirectory: /var/lib/check_mk_agent
SpoolDirectory: /var/lib/check_mk_agent/spool
PluginsDirectory: /usr/lib/check_mk_agent/plugins
LocalDirectory: /usr/lib/check_mk_agent/local
<<>>

<<>>
/home/heerr hanging 0 0 0 0
/home/kalea hanging 0 0 0 0
/home/hofbauerc hanging 0 0 0 0
…

I know this picture as a kind of debug diagnosis, to check if check_mk works properly and so on. But how did I (mis)configure this? I simply want my Login back :slight_smile:

It looks like you use an ssh key who is configured on your target machine to output the check_mk_agent output.
Can you check what ssh key you use here?

thanks, but I couldn’t figure out the root cause, especially the ssh key settings.
I double-checked .ssh/authorized_keys etc. , but nothing inside.
My unlucky solution was to remove the agent from the node, I had no other choice
