[Check_mk (english)] ssh via proxy (squid)

Hello list,

I have this windows machine acting as a MGMT station

We configured a squid service to connect to the nodes behind this mgmt server

If I set my .ssh/config file correct we can ssh into a node perfectly

host *

ProxyCommand corkscrew MySquidProxyServer 3128 %h %p

I would like to have my check_mk check the ssh service on a node via this squid-proxy-server

(A next step will be snmp query via the proxy)
