Hi, 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 at localhost user at 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

Greetings, I've been doing a little testing with the stdio forwarding support added in recent snapshots and have encountered one possible issue. First, I should say that this feature generally seems to work. However, I haven't been able to get it to work when connecting to a server running SSH.COM's product. The config file I am using is fairly simple: Host sfe1 LogLevel debug3

...eply: This appears to be a bug in OpenSSH, which only shows up when a TCP connection to a forwarded port is closed extremely quickly after being opened. The problem is here: [channels.c] static void port_open_helper(Channel *c, char *rtype) { int direct; char buf[1024]; char *remote_ipaddr = get_peer_ipaddr(c->sock); >>>>>> u_short remote_port = get_peer_port(c->sock); This is called very shortly after processing a connection opened on a forwarded port, channel_post_port_listener(). I couldn't replicate this by telnetting to the port, or even with a simple Perl program...
