SourceMod extension: how to get server's IP?

Hi.
How can I get server IP in sourcemod extension?

Re: SourceMod extension: how to get server's IP?

PHP Code:


		
			
#include <SteamWorks>



// [... all your other code ...]

    char sPublicIP[64];

    int iPublicIP[4];

    if (SteamWorks_GetPublicIP(iPublicIP)) {

        Format(sPublicIP, sizeof(sPublicIP), "%d.%d.%d.%d:%d", iPublicIP[0], iPublicIP[1], iPublicIP[2], iPublicIP[3], GetConVarInt(FindConVar("hostport")));

    } else {

        LogError("Appears like we had an error on getting the Public IP address.");

    }

// [... all your other code ...]

Now, the string variable "sPublicIP" holds the data "192.0.2.123:27015", assuming that the Steam network sees the public IP as "192.0.2.123", and the port is "27015".

PHP Code:


		
			
    Format(sPublicIP, sizeof(sPublicIP), "%d.%d.%d.%d", iPublicIP[0], iPublicIP[1], iPublicIP[2], iPublicIP[3]));

can eventually be used, if you don't like the port number to be a part of it.

That's one way of doing it for the plugin, I need to do it in extension :)

Well, the SourceMod > Scripting section says "Scripting in SourcePawn" for it's description. As such, due to your thread in a wrong section, I was somehow under the impression that your "extension" mention would be incorrect, and that you actually meant "plugin".

Moved to SourceMod > Metamod: Source > Coding MM:S Plugins & SM Extensions.

Re: SourceMod extension: how to get server's IP?

Thank you, I hadn't noticed this category at first. I've figured out how to do it, in case someone need this:

PHP Code:


		
			
    char serverip[32];
    int ip = g_pCvar->FindVar("hostip")->GetInt();
    int port = g_pCvar->FindVar("hostport")->GetInt();
    
    int iips[4];
    iips[0] = (ip >> 24) & 0x000000FF;
    iips[1] = (ip >> 16) & 0x000000FF;
    iips[2] = (ip >> 8) & 0x000000FF;
    iips[3] = ip & 0x000000FF;

    snprintf(serverip, sizeof(serverip), "%d.%d.%d.%d:%d", iips[0], iips[1], iips[2], iips[3], port);

"hostip" may not always return the real (public) IP address, such as for example if your server runs behind a router/NAT. In these situations, you may actually see the RFC1918 IP address ranges, e.g. 10.xx.xx.xx, 172.16.xx.xx-172.31.xx.xx and/or 192.168.xx.xx (the one that your server actually listens to on the actual machine).

That's true, however it should work for most dedicated servers (if started correctly).
