...channel type of SSH_CHANNEL_RPORT_LISTENER, c->host_port is 0 and therefore, per the above code, nextstate == SSH_CHANNEL_DYNAMIC and port_open_helper() is not called. I am not sure what the function of SSH_CHANNEL_DYNAMIC is but it looks like it has something to do with socks4 (from looking at channel_pre_dynamic()) and probably doesn't apply to the SSH_CHANNEL_RPORT_LISTENER case. I suspect that nextstate should be SSH_CHANNEL_OPENING in order to call port_open_helper(). I tried to make the change : nextstate = (c->type == SSH_CHANNEL_RPORT_LISTENER) ? SSH_CHANNEL_OPENING : (c->ho...

Using OpenSSH_8.3p1 I had an open (working) connection to some other box; after a bit of inactivity, some device in the middle seems to have forgotten about the TCP connection (NAT) and broke it. I've got an EscapeChar defined, though; so first I tried to send a BREAK and, when that didn't help (TCP already gone, packets get lost!), I tried (just out of curiosity) a Rekey. Now I can see
