HLDS - Protocol 47 and 48 at same time?

seba · **Joined:** 08 Sep 2007 18:55 **Posts:** 22

Hi Luigi.

There are two patches already relased, but they are too buggy to use it (ex. cbooster works only on bugged 3651 binary, source isnt published).

Can you do this? I think patch would decive HLDS to all players has protocol v47. When player connect, game client sends anything like this (from csdos.pl)

Code:

 $q=$cmd."connect 47 $c2 \"\\prot\\4\\unique\\0\\raw\\valve\\cdkey\\f0ef8a36258af1bb64ed866538c9db76\"\"\\\"\0\0";

I think in protocol v48 this is simply changed to "48", so enough to change it ? Strings looks similar (maybe change it to be same?) -> http://up.programosy.pl/foto/luigi.jpg
Thanks for advice.

EDIT: Oh :/ i changed it in memory editor to 47 and game freeze while connect :o I think string must be same, but how to do it, when lenght is different ?

Luigi, please, help me...

uhmmm sincerely I have not understood what is the subject.
I mean, a patch for fixing what exactly? fixing csdos or what?
for csdos/hlfreeze/btbp I released a patch various months ago:

No, no!

A few weeks ago VALVE updated STEAM version of game. What changed? Protocol number when connecting and -> http://up.programosy.pl/foto/luigi.jpg

I want to old CS 1.6 server (nonsteam) can accept new and old protocol at same time. This patch is already relased, but with no source / works only on bugged files.

ah ok now it's clear.
I need to know the exact error showed in the client when it tries to join and the swds.dll file.
for example here in hl 4.1.1.1e the handling of the protocol number is bypassable through a 0xeb at offset 0x00081AD5 of swds.dll where it's enough to search the phrase "This server is using an older..." but naturally the messages could have been changed in the Steam versions.

OK :)

Error message -> http://up.programosy.pl/foto/message1.jpg (of course "www.cs-puchatek.pl" is a server CVAR).
swds.dll from steam version ? I cant find it in gfc packages oO (look -> http://up.programosy.pl/foto/message2.jpg + http://up.programosy.pl/foto/message3.jpg). I looked in these files for this message, but... no results.

PS. Maybe you have not understood me, buy I'm wanting patch for linux server, excatly for this file -> http://www.speedyshare.com/255665224.html

Really thanks.

ok done:

http://aluigi.org/patches/hlanyproto.lpatch

this one should work with any version of half-life on both windows and linux.

You are a god! :)

but when I try to connect with steam version I get message

Code:

STEAM validation rejecte

and into server console

Code:

SteamStartValidatingUserIDTicket: Returned ESteamError 25

Any suggestion (maybe patch to total disable validating user id tickets?) ?

====

EDIT: I used esteamation patch to disable validation userid tickets, and "works". But when I connect, at "parsing server info" message kick's me with message

Code:

Hmm ? What with this

Code:

?

aluigi · **Posted:** 03 Feb 2009 11:21

try using the updated attached patch (I will update the one on the website when we will have the definitive one)

Ok, ticket validation is disabled.

Now only problem with steam clients [code]
Server returned version 47, not 48[/code] any way to fix this ?

I really need this, of course thanks for your time!

aluigi · **Posted:** 03 Feb 2009 11:45

done, new version attached

Well, but if you hardcore protocol numer 48, players with 47 cannot connect.

Have you any idea (maybe small metamod plugin? I'm only AMXMODX plugins writter, so I dont know how to do this oO)?

aluigi · **Posted:** 03 Feb 2009 12:06

the protocol is hardcoded and the client reads it from the server's packets and compare it with their own so you can't allow any client protocol to join, you are obbligated to choose what client protocol allowing in your server.

Look into attachment. I uploaded small metamod plugin which allow protocol 47 and 48 to play (and additionally allow to add old server to masterlist, but this is useless - now fixed).

Why I dont using this? Because not working with 2738 (http://www.speedyshare.com/255665224.html) binary.

aluigi · **Posted:** 03 Feb 2009 12:37

this is something not possible with a binary fix.

a lame "idea" would be to insert an instruction in SV_CheckProtocol which writes the current client protocol in the hardcoded one of SV_SendServerinfo but it's not possible to make this thing "universal", has the downside of being not thread-safe (because it's just a work-around without the possibility to use an internal database interfaced with SV_SendServerinfo and its client_t argument) and I don't know what's the address of your SV_SendServerinfo at runtime.

Hmm, you believe this is too hard... so can you explain me how "cbooster" work? Maybe can you patch this "cbooster" file to work with older binary ?

On 3651 works and tell

no, I have said that it's not possible through a "binary fix" and that cbooster is not a binary fix but a hooker.
then it performs the hooking of recvfrom which is superflous (not that I have not tested it and I have neither disassembled it so the hooking of recvfrom could be related to another feature of the tool), in fact hooking SV_CheckProtocol is possible to get directly the IP and the protocol of the client without loosing CPU cycles doing the manual parsing.

the fact that it doesn't work with your version is probably caused by the pattern (the bytes to find) which is not the same as in the version for which was created cbooster

Yeah, I already tried this.

Hi Luigi.

Can you add to this patch one feature - disabling cdkey checking (to remove "invalid cdkey" message) ?
