FAQ (in development)
Q: What is dproto? A: Dproto was made as replace for cbooster on double-protocoling solutions area. dproto designed to work for new p.48 HLDS, so all steam features can be used with it. Dproto has one primary goal - to allow old clients to join new servers, all another features are secondary and they were added by users requests.
Q: How to install dproto? A:
1. Go to <gamedir>/addons/ and make new directory named dproto <gamedir> - its a game directory; cstrike for Counter-Strike, valve for Half-Life, etc 2. Copy dproto.dll or dproto_i386.so to <gamedir>/addons/dproto/ 3. Go to metamod installation directory (usually its <gamedir>/addons/metamod/) and edit plugins.ini: add this line for windows win32 addons\dproto\dproto.dll or this for linux linux addons/dproto/dproto_i386.so at the beginning of the file 4. Copy dproto.cfg to server root or gamedir. 5. Start the server. You should use this command on linux: ./hlds_run -binary ./hlds_i686
when server loads, type "meta list" in console. You'll see something like this: Currently loaded plugins: description stat pend file vers src load unlod [ 1] dproto RUN - dproto_i386.so v0.4.3 ini Start Never [ 2] AMX Mod X RUN - amxmodx_mm_i386. v188.8.131.52 ini Start ANY 2 plugins, 2 running 6. Enjoy
Q: I installed dproto, but it does not work. meta list says this:
Q: I dont see my server in steam favorites! A: Set ServerInfoAnswerType to 0 or 2 in dproto.cfg
Q: My server is invisible in favorites in cs v24! A: Set ServerInfoAnswerType to 1 or 2 in dproto.cfg
Q: How to make my server visible both in old no steam clients and steam? A: Set ServerInfoAnswerType to 2 in dproto.cfg
Q: I'm getting "Error verifying STEAM UserID Ticket(server was unable to contact the authentication server)" error when playing on legit client. Q: Bans for legit SteamID do not work. Users with banned IDs are able to play on server. A: Your server can't conect/lost connection to steam servers. I dont know universal method to check connection to steam servers (if someone know it - pls tell me). If you have VAC secured server, use stat command. If it shows version as "insecure" or "insecure (secure mode enabled, disconnected from Steam3)" it means that connection to steam servers lost. This problem is not related to dproto, but i can give some tips to fix it: 1. Check if outgoing TCP connections are allowed to destination port 27030 2. Check if outgoing UDP datagrams are allowed from local ports 2690x 3. If you using linux, you should add +ip <server ip> parameter to command line. I'm using +ip 0.0.0.0 for example and it works fine.
Q: My server could not be displayed in monitoring system. A: It's because of hybrid answer type, some monitoring scripts cannot handle it correctly. There is 3 way to solve the problem: use standart answers (ServerInfoAnswerType = 1 or 0) or try to fix it by yourself, or write to script developers.I dont guarantee correct work of third-party stuff.
Q: I'm using latest engine and my server is not visible in internet list. A: Forward this question to Valve
Q: I'm using latest engine and my server is not visible in Setti serverlist. A: Register your server [[Please login to see this link.]]
Q: My server crashes sometimes after N days of work... A: Forward this question to Valve
Q: My server crashes when i installed mod X on it. A: Forward this question to mod X developers and check if you haven't missed something.
Q: I have players with same steamids on my server. They're recognized as SteamEmu (dp_SteamEmu) A: Steamid could be easily spoofed in SteamEmu auth algorithm. Deprecate these clients or set not-numeric id to them (STEAM_ID_LAN for example)
Before posting bugreports and questions...
Make sure that dproto is reason of the bug. You can check it by disabling dproto.
Please, don't post there questions about HLDS engine bugs that were known before release of dproto. I'm not going to spend my time for analyzing engine for free.
Post all "My server does not displayed in internet list" questions in Valve's forums. Native Master-Client located in steamclient.dll (steamclient.so) and dproto could not be a reason because it does not patch this library.
Bugreport MUST contain:
Detailed explanation of bug.
A way how to reproduce it (if possible)
Full startup log from server console; server should be started with "+log on +mp_logecho 1" parameters
Contents of dproto.cfg
MD5 hashes of all files from server root directory (use [[Please login to see this link.]] for Windows or [[Please login to see this link.]] for Linux)
I won't consider bugreports without these points because I don't want to spend my time to search possible reasons of your problems. Thanks for understanding.
Post all problems/bugs you have found in this topic.

Sniperkiki, this problem should be solved by OS administrator. And I can't add this to FAQ because there is no universal solution to solve this, because different OSes uses different package managers and different package names. For example, on x64 Ubuntu package "lib32stdc++6" should be installed, but on debian x64 it's "ia32-libs"

Were talking about Valve here They don`t fix anything. Even the hlds_vcrash is fixed only on 4883 linux build. On windows is still 4554 (8 march build), without dproto every windows server (steam only) is vulnerable.
