[CoD2] Setup CoD2 on your Ubuntu server

[Loveboy]

Somehow I only can start the server on localhost, but I would like to make the server available for everyone.

When I run the server.sh, console tells me:

		Opening IP socket: localhost:28960 
	

I tried to set dedicate to 2, so that the server is for everyone available.
Now the console this

		dedicated is read only. 
	

I am not sure if it's an error or warning, but it's still running on localhost.

This is my server.sh (which is inside my CoD2 folder):

		#!/bin/bash

cod="/home/CoD2/cod2_lnxded_1_3"

$cod +set dedicated 2 +set fs_game "loveboy" +set com_hunkMegs "256" +set sv_maxclients "16" +exec server.cfg +set g_gametype hq +map_rotate 
	

I also tried to set the net_ip with my real IPv4 address

		$cod +set dedicated 2 +set fs_game "loveboy" +set com_hunkMegs "256" +set sv_maxclients "16" +set net_ip "12.34.56.78" +exec server.cfg +set g_gametype hq +map_rotate 
	

but the server crashes.

The error:

		Opening IP socket: 12.34.56.78:28960
ERROR: UPD_OpenSocket: bind: Cannot assign requested
Opening IP socket: 12.34.56.78:28961
ERROR: UPD_OpenSocket: bind: Cannot assign requested
Opening IP socket: 12.34.56.78:28962
ERROR: UPD_OpenSocket: bind: Cannot assign requested

... till :28969

Sys_Error: Error during initialization:
Couldn't allocate IP port 
	

I also tried to open port in my firewall

		iptables -A INPUT -p udp -d 12.34.56.78 --dport 28960 -m state --state NEW -j ACCEPT 
	

and tried to check it with

		iptables -L 
	

and found my new entry (successful), but still same errors.
My opened port disappears when I restart ubuntu.


Does anyone maybe know what to do?
