Oh, btw., I never saw that test program. However, calling bind
before calling connect is superfluous and a bit dangerous since
from MSDN:
Client applications usually need not call bind at all. connect
chooses an unused port automatically. When bind is called with
a wildcard address (involving ADDR_ANY), a WSAEADDRINUSE error
could be delayed until the specific address is committed. This
could happen with a call to another function later, including
connect, listen, WSAConnect, or WSAJoinLeaf.
So, I'm a bit tired right now (about midnight)... does SSH call
bind before connect?
