Hello,

I'm trying to search a value that is unique for every servers and that can be shared. Something like an ID in a database table.

Is there such a thing ? I'm just trying to indentify my servers.

Add auto increment field to DB along with hostname.

Use INSERT INTO ON DUPLICATE
UPDATE mysql syntax.

But hostname can change ? I mean, for exemple, I know some server change there hostname like this :

Bla bla bla server name | some more infos | 7/32 players

A few minutes later :

Bla bla bla server name | some more infos | 2/32 players


And now I have 2 entry for the same server. Also, I'm not doing any SQL or anything. I'm just trying to find something unique to every server.

Every server downloads the same binary files from the server and should be identical by default. The only variables that are kind of static that you could use would probably be the ip address + port combination. of course these can change too but so can anything if you change it... Other then that i'd suggest you create the unique identifier for each server. It all depends on what you are trying to accomplish exactly

The thing is, I create socket on servers and once in a while (map change, server reboot, etc...) socket get destroyed or disconnect, without notifing the main server (and it's normal). Immediatly after, the server's socket reconnect, but now I have 2 entries. The 'old' connection and the new one. I'm forced to send a data to the 'old' socket and see if it crash (doesn't bother me too much) but then I don't know for sure what's the new correct socket for that server.

I am using IP+port combination already (and checking server's hostname, but that's not safe), but as you said, it can change.

EDIT: Not sure if it was clear enough ?

I believe IP: Port is the most unique property a server has. Yes, it can change, but it's not like you change your server's IP every day. Another way would be that each server has a UUID that it should keep sercret and use that to identify itself.

P.S. I don't know if UUIDs are cryptographically secure. But there are many other algorithms you can use to generate a secret key.

Alright, thanks. I don't really need it to be secure. I just need something to select servers distinctly.

Yes.

The GSLT systems helps you, e.g.:

status
[...]
udp/ip  : 127.0.0.1:27015  (public ip: 127.0.0.1
steamid : [G:1:123] (12345678901234567)
[...]

^ The "steamid" is unique, based on the GSLT for your server (e..g. sv_setsteamaccount).

The Server Steam ID can be retrieved via GetServerSteamAccountId (short "123" from "[G:1:123]"), and GetServerAuthId (long "12345678901234567").

I would suggest taking the long one though, as the "64-bit Steam ID's" are the only one that hasn't ever changed it's "format".

The Server Steam ID will be a better factor to use (at least, for games that supports that, such as CS:S, CS:GO, and TF2).

Use the "advantages" of the GSLT system.

Not if you take the GSLT system into consideration.

Only places where the GSLT system won't work properly, would be if you are running nasty things where you "need" to change sv_steamaccount frequently, otherwise "steamid" will always be the same for the same "sv_setsteamaccount" token.

GSLT is your best bet.

It will only complicate things, if you need to support those kind of nasty things that Valve is actually blacklisting servers for.

The account IDs have never changed, it's just that Valve had a weird way of displaying them in SteamID2. Instead of the account ID being a single number, they did this:

STEAM_x:last bit:remaining bits shifted right by 1

STEAM_x because it'll be either STEAM_0 or STEAM_1 depending on whether the game is misreporting the realm as Invalid (0) or not (1)

Hence why STEAM_1:0:1081621 changes to [U:1:2163242] because (1081621 << 1) | 0 results in 2163242

@arne1288 I knew about GSLT, but does that apply to all Source games? I know it's required for some games.
