Logging IPs with ULX Possible?! Let's see how!

[Snugzz]

After numerous trolls on my server that would come back with a family shared account I decided to ban their IP. Well I couldn't do so without their actual IP. Yes I could take the long way and go through my console and then get it that way and then "ban ip XX.XX.XX.XX" but who has time for that! ULX comes ready to log IPs.  .

Here's how!

1) Navigate to your install of ULX ( Normally garrysmod>addon>ulx).
2) Nroceed further into the files (garrysmod>addon>ulx>lua>ulx>log.lua)
3) Open log.lua
4) Go to line 191, here you can see 

Code: Lua

1. local function playerInitialSpawn( ply )
2.         local ip = ply:IPAddress()
3.         local seconds = os.time() - (joinTimer[ip] or mapStartTime)
4.         joinTimer[ip] = nil
5.  
6.         local txt = string.format( "Client \"%s\" spawned in server <%s> (took %i seconds).", ply:Nick(), ply:SteamID(), seconds )
7.         if logEvents:GetBool() then
8.                 ulx.logString( txt )
9.         end
10.  
11.         if logJoinLeaveEcho:GetBool() then
12.                 echoToAdmins( txt )
13.         end
14. end
15. hook.Add( "PlayerInitialSpawn", "ULXLogInitialSpawn", playerInitialSpawn, HOOK_MONITOR_HIGH )
16.  

As you can see they still have the function left within ULX. Now it's just a matter of slightly editting the few lines of code to log IP addresses.

AS I have been unsuccessful with logging them this way I just editted a script to work just about the same way

Here for you want to take the easy way out.

Code: Lua

1. hook.Add("PlayerInitialSpawn", "SaveIP", function( p )
2.     if p:IPAddress() != nil then
3.         file.Append("ips.txt", "Player "..p:Nick().." has connected from the IP: "..p:IPAddress().." and with the Steam ID: "..p:SteamID().."\n")
4.     end
5. end)
6.

I wouldn't recommend using IPs as a permanent ban, as most people connecting to Gmod servers are on DHCP.
That, and we took IPs out of ULX for protection of clients (security exploits)

If I were a troll, I could get around your IP ban with a family account in less than 3-4 minutes, faster if my router weren't more than 5 years old.
I'd recommend using any number of Steam API family check scripts.
This one here, though I never tested, seemed like it would work in theory.

I will also link my addon if that's okay.

I wrote it to combat players that avoid bans via Family Sharing, a few months ago. It will automagically ban the parent account that owns the game as well as any child accounts trying to access via Steam Family Sharing. It makes use of the Steam Web API to do that. You can find instructions on how to set it up inside the topic.
