I have the following SSH-client configuration in my local home directory:
client$ cat ~/.ssh/config Host foo.example.com ProxyCommand /bin/nc 192.168.0.10 2000
This configuration forwards SSH connections to foo.example.com to foo's internal (Docker) SSH service.
It works, but it is a client-side configuration. I need the same setting at server-side. I tried
server$ cat /etc/ssh/sshd_config ... ForceCommand /bin/nc 192.168.0.10 2000 ...
but it doesn't work. Any suggestions?
