Help With Online Master Server

[copthesaint]

Ok Here are my 2 first programs That I had made, and it worked the first time I did this.(without arrays/processes)
But now My Server doesn't seem to send the welcome text which is ("Welcome To CopTheSaints Server.Please Enter your User Name" : Line (31 Master Server.t))
Is this just not working because I didn't use arrays for the client or what? Please Help if you can or enlighten me.

ummm, it works for me...or maybe i'm not understanding your problem..that may be it,

is it your 'Master Server.t' thats not working?

because sometimes it says "Welcome To CopTheSaints Server.Please Enter your User Name", sometimes it doesn't, i don't really know why its doing it though . . . .

Hmm Here is a newer version I was working on but I keep getting runtine errors. anyone wanna see whats wrong?
It's will run fine untill it gives me this weird never seen before error. The error will tell you that line 24 is having an error.

Windows Socket Libary Error % 10048'.


(Btw there will be a pause connecting to the the program.)
Also if you o fix it post the code please. I am not going to be graded on this project.

Basically, what that error means is that something on your system has already claimed that port. Assuming you chose something over 1024, try closing Turing and retrying. If not, check your code to see if you're trying to listen again on the same socket (ip, port).

Ohh! I need to change the port for every client ! thanks demon for url
Ill see if this works

Actually, there's another solution that works better for multiple clients, but it's slightly more complex.

See, the thing is, for a server you want it to always be listening on the same port. So ideally, it shouldn't have to change ports for different players - they always connect to SERVER_LISTEN_PORT or whatever. It's possible to do this, and it goes like this:

1. Listen on SERVER_LISTEN_PORT
2. When you get a connection, immediately send another (unused) port number and close the connection.
3. Listen on the port mentioned in step 2.
4. When you connect on that port, start sending data to that client however you will. Meanwhile, return to step 1.

This isn't perfect (real networking solutions do it better...) but it's the best you're likely to get in Turing.

Well I didn't do what you are were saying but I got a working server made. I will post again when I have another problem or error.
