I''ve written a basic socket class and it will listen/connect and send/receive data over my LAN just fine. However I cannot connect or receive a connection from my friends machine over the internet. Is there anything specific that needs to be done programming wise to accept a connection over the internet vs over a LAN? The sockets are all stream sockets, initialized thus: s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); Then I bind the server socket to INADDR_ANY and I connect the client socket to the server. Anything here I''m forgetting that would cause it not to work over the internet? Or should I just try some different friends? TLR

If you''re using cable, does you''re router have a firewall????

Nope, I wish it was that easy. I''m on a dialup connection, and there''s no firewall or anything.

There is absolutely no difference in the socket''s themselves. Maybe you could be a bit more specific regarding the error(s) you get and what exactly seems to be the problem?

Don''t forget that network addresses and port numbers have to be in network byte order - so use htonl and htons to convert the address and port number respectively.

Other than that I can''t help you without some kind of error code or snippet of your code.

When the client tries to connect, it gets a WSAETIMEDOUT error. The machine that's acting as the server is using Win98 SE, and I have internet connection sharing installed on it. Does that do anything that might screw it up? To I need to bind to something other than INADDR_ANY?

First ping your friend''s PC. Open up ms dos prompt and type
"ping xxx.xxx.xxx.xxx", replacing the x''s with your friends IP
address. then get your friend to ping you. If both pings are successful, there should be no reason your program doesn''t work.
