I have a client and server using socket to transfer data. I give a port
number 111964.
After start program everything is fine. But I found that my program is
not using the port number I give. (lsof -p12321, 12321 is process ID).

Is that my port number too large?
What is the range of port number?

Thanks

Gary

No, you don't. TCP and UDP ports range from 0 to 65535; the port you
_say_ you use is well beyond the upper bound of that range.
