Is my Socket Free or Listening

Hi,

Code:
bash-3.2$ uname -a
Linux mymac 2.6.18-409.el5 #1 SMP Fri Feb 12 06:37:28 EST 2016 x86_64 x86_64 x86_64 GNU/Linux

bash-3.2$ telnet 10.12.228.40 13900
Trying 10.12.228.40...
telnet: connect to address 10.12.228.40: Connection refused
bash-3.2$ telnet 10.12.228.40 23900
Trying 10.12.228.40...
Connected to 10.12.228.40.
Escape character is '^]'.
Connection closed by foreign host.

bash-3.2$ telnet 10.12.228.40 24000
Trying 10.12.228.40...
telnet: connect to address 10.12.228.40: Connection refused

This makes me believe 10.12.228.40 24000 is free for use.

But when i start a process on that socket 10.12.228.40 24000 it fails saying
Code:
The address 10.12.228.40 might be incorrect or another process is using port 24000: java.net.BindException: Cannot assign requested address

Please explain.

Does it fail on every port or just that one? If it fails on every port, it might have some other problem.
