| |
| | |
| ===IP:Port===
| |
| Steam sends "0.0.0.0:0".
| |
| | |
| Does anyone know what this is supposed to be the address of?
| |
| | |
| Changing it doesn't appear to affect the results in anyway.
| |
| | |
| (Should be the first IP address we are interested in.)
| |
| | |
| ===Filter===
| |
| Allows you to restrict the results to servers running a certain game, map, etc.
| |
| | |
| Send an empty string (0x00) to recieve a list of all types of servers.
| |
| | |
| Insert <code>\</code> in between filter parameters
| |
| *<code>\type\d</code>
| |
| ::Servers running dedicated
| |
| *<code>\secure\1</code>
| |
| ::Servers using anti-cheat technology (VAC)
| |
| *<code>\gamedir\[mod]</code>
| |
| ::Servers running the specified modification (ex. cstrike)
| |
| *<code>\map\[map]</code>
| |
| ::Servers running the specified map (ex. cs_italy)
| |
| *<code>\linux\1</code>
| |
| ::Servers running on a Linux platform
| |
| *<code>\empty\1</code>
| |
| ::Servers that are not empty | |
| *<code>\full\1</code>
| |
| ::Servers that are not full
| |
| *<code>\proxy\1</code>
| |
| ::Servers that are spectator proxies

| ==Master Servers==
| |
| Current master servers are
| |
| | |
| '''Half-Life 1 engine:'''
| |
| | |
| <code>207.173.177.11:27010</code>, <code>69.28.151.162:27010</code> and <code>68.142.72.250:27010</code>.
| |
| | |
| '''Half-Life 2 (Source) engine:'''
| |
| | |
| <code>68.142.72.250:27011</code>, <code>69.28.151.162:27011</code> and <code>207.173.177.11:27011</code>.
| |
| | |
| '''Rag Doll Kung Fu:'''
| |
| | |
| <code>207.173.177.12:27012</code>.
| |
| | |
| If you can, get your application to check the file <code>Steam\config\masterservers.vdf</code> to get the latest list of master servers.
| |
| | |
| ==Reply Format==
| |
| The reply always starts with <code>FF FF FF FF 66 0A</code>.
| |
| | |
| The format is then a series of these server address blocks:
| |
| {|
| |
| ! Type || Data
| |
| |-
| |
| | [[Byte]] || First octet of IP address
| |
| |-
| |
| | [[Byte]] || Second octet of IP address
| |
| |-
| |
| | [[Byte]] || Third octect of IP address
| |
| |-
| |
| | [[Byte]] || Fourth octet of IP address
| |
| |-
| |
| | [[Short]] || Port number - usually 27015 (0x69 0x67)
| |
| |}
| |
| | |
| Some of the servers may be unreachable, so query each server directly to find out. Note also that this list is not exhaustive, so if you're looking for a particular type of server make sure that you specify a filter with the query, rather than filtering client side.
