https://bugzilla.mindrot.org/show_bug.cgi?id=2256

            Bug ID: 2256
           Summary: ssh - Connection closed by UNKNOWN
           Product: Portable OpenSSH
           Version: 6.6p1
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: minor
          Priority: P5
         Component: ssh
          Assignee: unassigned-bugs at mindrot.org

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 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 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.
