I'm building the user.sessions file from a source which does not provide IP adresses and I need to use a jump server.
When I try to connect to a session I receive this message : "Channel opening failure: channel 43 error (2) Address family for hostname not supported".
I think this is because my client resolve hostnames as IPv6, the jump server can resolve them as IPv4.
I'm building a similar file for mobaxterm and it works well.
