hlmaster-bun — Master Server Status

Your game server needs two plugins installed on ReHLDS:

1. ReUnion — accepts non-Steam clients (protocol 47/48)
2. rehlmaster — custom master server registration

reunion.cfg — key settings to verify (defaults already allow p47/p48 clients):

1AuthVersion = 4
2SteamIdHashSalt = YourSecretSaltHere16PlusChars
3ServerInfoAnswerType = 0
4FixBuggedQuery = 1
5EnableQueryLimiter = 1

SteamIdHashSalt is required with AuthVersion >= 3. Use a random string of 16+ characters. This prevents SteamID theft between servers.

reauthcheck.cfg — if you have ReAuthCheck installed, disable the per-IP connection limit to avoid kicking legitimate players from shared networks (internet cafes, NAT, VPN):

1CheckMaxIp = 0

server.cfg — add these lines to register with this master server:

1sv_master1 ms.cs16.net:27010
2sv_master2 master1.cs16.net:27010

Once configured, your server will send heartbeats automatically and appear in the server list within a few minutes. If verification is enabled, the master server will query your server to confirm it is reachable.

You can also add your server manually using the form above.

Anniversary

Goldclient

Steam Legacy

Download the correct version for your game client from the latest release:

Steam Legacy & Anniversary

Extract the zip and copy the contents into your Half-Life folder:

Half-Life/
├── mastersrv.dll                  <- new !!
└── platform/
    ├── config/
    │   └── MasterServers.vdf      <- new !!
    └── servers/
        └── ServerBrowser.dll      <- replace ?✓

Launch with -insecure flag.

GoldClient / CSPro

1. Replace steam_api.dll in your game folder with the patched version from the zip
2. Append the contents of hosts_append.txt to C:\Windows\System32\drivers\etc\hosts (run Notepad as Administrator)

The hosts file blocks depot.cs-play.net and renewal.cs-play.net to prevent the auto-updater from reverting the patch.

Configuration

Edit platform/config/MasterServers.vdf to customize master servers:

1"MasterServers"
2{
3    "hl1"
4    {
5        "0"
6        {
7            "addr"    "ms.cs16.net:27010"
8        }
9    }
10}

Add as many entries as needed — the server browser queries all configured masters and merges results. If the VDF file is missing, the default master ms.cs16.net:27010 is used.
