[COD4]How to make cracked server show in master list?

Hello,
I am on linux box, running few cod4 servers and I need some help making them show in master list.

I did some changes in my iptables:

Quote:

---

-A INPUT -p udp -m udp -m string --sport 20800 -j DROP --algo bm --string "BANNED_CDKEY"
-A INPUT -p udp -m udp -m string --sport 20800 -j DROP --algo bm --string "INVALID_CDKEY"
-A OUTPUT -p udp -m udp -m string --sport 20800 -j DROP --algo bm --string "INVALID_CDKEY"
-A OUTPUT -p udp -m udp -m string --sport 20800 -j DROP --algo bm --string "BANNED_CDKEY"

---

and using original bins, it's not working.. msg is "key code is in use".
I need little help here and may be patched bins too :(

I found a way to fix it. Unfortunately it is not working with ip tables at all.
Just find getIpAuthoruze in bin file, using hex editor and rename it (first one) with something else, so it will not get IP authorization for clients who want to connect to the server. That's it. :)

Thanks goes to IzNoGoD, who point me to right direction :)

Happy new year to all

I dont think I had anything to do with it.
Might have been mitch?

Hello,

i renamed getIpAuthorize to other letters, but now i'm getting: "Key Code in use. Please try reconnecting later."

Can anyone help me with this? I want to run cod4 cracked linux server which should be shown in master list. Thanks!

Hi,

I'm also attempting this and had the same issue as jankarl ^^^

Anyone know the solution? Cheers

Couldn't seem to edit my last post..

Found this after more googling:

I will look into the porting my cracked solution from cod4 to cod2 when i got time.

See:
https://github.com/kungfooman/libcod...ter/libcod.cpp (hook call of AuthorizeState: line 1944)
https://github.com/kungfooman/libcod.../functions.hpp (requires addresses of Cmd_Argv, Cvar_VariableValue and hook_AuthorizeState_call)

Ok, it seems that my cracked solution from cod2 doesn't work in cod4. Cvar_VariableValue should be 0x0819E7C0.

You could hook all the calls in this function to sub_81AAAE2. (which compares the state with deny or accept)

I think this should do the trick:

PHP Code:

---

int hook_StateCompare(char * state, char * base)
{
    if ((CvarVariableValue == NULL || CvarVariableValue("sv_cracked") == 1) && strcmp (state, "deny") == 0) // when sv_cracked 1 and deny state
    {
        if(strcmp(base, "accept") == 0) // when compare value is accept return true
            return 0;
        else
            return 1; // when compare to value is deny return false
    }

    return strcmp(state, base);
}

#if COD_VERSION == COD4_1_7
    cracking_hook_call(0x0816FF42, (int)hook_StateCompare);
    cracking_hook_call(0x081701D6, (int)hook_StateCompare);
#endif 


---

Basically it changes the compare function to returning false (1) when it compares deny to deny. And it returns true (0) when it compares deny to accept.

Shouldnt this be more like

PHP Code:

---

int hook_StateCompare(char * state, char * base)
{
    if (CvarVariableValue == NULL || CvarVariableValue("sv_cracked") == 1) 
        return 0;
    return strcmp(state, base);
}

No, because I hook these 2 calls.

PHP Code:

---

if ( !sub_81AAAE2(v16, "deny") )
result = (void *)sub_81AAAE2(v16, "accept");
