Set all RESOLVED bugs to CLOSED with release of OpenSSH 7.1 |
Created attachment 2456 [details] add set_remote_ipaddr() ssh clients shows "closed by UNKNOWN" message when a socket is closed by a remote side while ssh is waiting for user's password: $ ssh user@localhost user@localhost's password: Connection closed by UNKNOWN When the packet_read_seqnr() calls get_remote_ipaddr(), a connection's socket is already closed and there's not been any other call of this function yet so canonical_host_ip from canohost.c is still NULL and the function returns "UNKNOWN". I think that it could be workarounded by calling get_remote_ipaddr() right after packet_set_connection(), e.g. using another debug message, see bellow, or there could be set_remote_ipaddr() in canonhost.c for that.
