[Mono-list] TCPListener problem

[Lee]

Hello, 

I have done what Martin suggested which was the following:

Specifically use localhost 127.0.0.1 as the local address and check netstat.
It appears that the socket does not start because it is not showing up in
netstat.

As I mentioned in a prior post, I have placed logging routines at various
points in the code:

OnStart event
OnStop event
Beginning of the StartServ() method

When I used:
SockServer = new TcpListener(IPAddress.Any, port);

Both the OnStart and OnStop events were firing without the socket server
listing.

When I changed to:
IPAddress addr = IPAddress.Parse("127.0.0.1");
SockServer = new TcpListener(addr, port);
...only the OnStart event appears to fire.

Again, If I run the socket server (both in and out of VS IDE) on Windows the
server works fine with no problems.  Could it be that there is a difference
in the implementation of sockets namespace in Mono has a difference that I
need to account for?

Thanks again,

Lee
