Telnet connections

Hello, my program listens on port 23 for telnet connections, it works fine accept for when I try to recieve some data. It recieves the correct data, but it also fills up the rest of the buffer with useless junk. How do I stop it sending me all this rubbish? Or is there a way to filter out the actual data?

thanks everybody.

Use the length returned by the recv() call rather than assuming that a \0 always exists in the place you expect it to.

Code:

---

char buff[BUFSIZ];
int n = recv( fd, buff, BUFSIZ-1, 0 );  // allow for adding a \0
if ( n > 0 ) buff[n] = '\0';

thank you very much.
