Blocked the ports as described earlier

But somehow my server aint showing up in the master server list, even after 30 minutes. Do i have to wait longer? Or did i do something wrong or have to do more?

There is no libcod support for semi-cracked server(s) on Windows.

Edit: best method for semi-cracked servers is with libcod (Linux) and having sv_cracked to 1.
Edit 2: The first post only works if you can filter that certain packet (which prevents cracked players from joining).
This method has a side effect that could give a cracked player a guid from someone else.

There is a way to make a cracked server only cracked for the players who cannot join servers that are original. The workaround has two steps.

First you gotta block the packets that the master list sends to the server that say that the player that is connecting isn't allowed to join the server, because he is banned or has an invalid key. This is done by blocking it using the firewall.

In this case iptables:

Code:

---

iptables -A INPUT -p udp -m string --algo bm --string "BANNED_CDKEY" --sport 20700 --dport 28961 -j DROP
iptables -A INPUT -p udp -m string --algo bm --string "INVALID_CDKEY" --sport 20700 --dport 28961 -j DROP

---

If your server has a other port, change the dport to the port your server uses or remove it to make it drop every packet.

Now there is one problem left. There is a ~30 minute delay for cracked before you can join them. So if a player joins he will keep connecting for a long time.
You can fix this by patching (hexing) the binary like is done in the latest cracked binary. I compared the original and the cracked binary and this is how they solve this issue:

Original (address 45429h) (patch 1.3)

Code:

---

80 4F 12

---

Patched

Code:

---

9A 10 00

---

This is binary i patched for 1.3: Attachment 255

Now cracked players can join your original server and you will still have your guid. Also your server will show up in the master list =].

This worked great for me! I downloaded cod2_lnxded_1_3_nodelay.zip from: https://killtube.org/showthread.php?...-(1-0-1-2-1-3)

To start my server, i log in to my server using SSH and execute the following script:
#!/bin/bash
cd /home/cod2server/
sudo iptables -A INPUT -p udp -m string --algo bm --string "BANNED_CDKEY" --sport 20700 --dport 28960 -j DROP
sudo iptables -A INPUT -p udp -m string --algo bm --string "INVALID_CDKEY" --sport 20700 --dport 28960 -j DROP
screen -S cod2screen -m ./cod2_lnxded_1_3_nodelay + set rcon_password "xxxxxx" + exec Config.cfg

When i reconnect later, i can restore the server console by typing: screen -r

Can someone explain to me how I make my cracked server show up in the master server list ? I have been looking in this post but couldn't find anything about WINDOWS system and which file crack should I use ?

You want a real guid
on a cracked server
so people with a cracked version of the game get a guid from the masterserver
because the masterserver is so generous it gives out guids to everyone, including cracked players?


That was sarcasm btw.
