I don't understand how to do this. I've created .ssh/config as you
guided me. Now I have the following error:
nc: getaddrinfo: hostname nor servname provided, or not known
ssh_exchange_identification: Connection closed by remote host
Isn't it because host B can't connect to host C directly? They're in
different networks actually.
