This is a full-featured port of LuaSocket for GMod. I've tried a simple socket thing, which worked out just fine.

Installation instructions:

Extract that archive in garrysmod/lua/includes/modules.

You will need the VS2008 runtime libs, or else you'll get a strange error while loading: http://www.microsoft.com/downloads/d...displaylang=en

Don't ask any questions unless you've installed that (and rebooted)

Usage:

Just like LuaSocket, see this for a reference: http://www.tecgraf.puc-rio.br/~diego...reference.html

Don't forget forget to use non-blocking sockets (set timeout to 0) or else GMod freezes while waiting for data!

Source code:

It's a VS 2008 project, should work in the Express version.

Thanks to:

Sechs - helped me with testing in #luahelp
Jinto - provided the Lua import library

Small example:

require("socket")
local s = socket.connect("www.google.com", 80)
s:send("GET / HTTP/1.1\n")
s:send("Host: www.google.com\n")
s:send("User-Agent: GMod10\n")
s:send("Connection: Close\n")
s:send("\n")
local line = s:receive('*line')
print(line)
s:close()

I don't know if that is correct but it should give you an idea about how it's used. You don't even have to use it manually, there are some helper modules too (http, smtp, ftp), but they don't seem to work. they probably would with some modification.

I'm curious as to what kind of things this could be used for/what it does. I'm guessing this is one of those things that other programmers will use to make something cool and I'm not a programmer, so this is of no use to me.

Is it something you'd use to send commands and info from server-client and back or something?

You could make anything that uses the internet with this. You could clone a server onto another (send all prop info etc), make a simple web browser, send email, anything...

Awesome. :)

I'd really appreciate it if anyone tried this out, I have no idea if it'll even load on other computers.

Woo hoo, now I can finally make mailbomb script.

This will prove useful :D

Quick question, I use VS2008E and what type of project (VB, C++, WD)I know it is not C#. Please clarify this for me. I have limited HD space and do not want to delete alot of files.

It's C++

Nice job :)

You don't need the source code if you're not planning to modify the DLL itself

With both this and the old gm_socket dll whenever I try and use it, it'll create a socket fine, but when I try and do something it'll tell me the socket is closed.

Then you're doing something wrong (show me the source code)

Exactly what I need for cross-server communication.

Excellent work, now I have to make a porn spidering script. I think I'll call it "GPorn".

It was reported to me that the included LUA modules (socket.http) etc aren't found by require(), so you'll have to figure that out if you need those. Shouldn't be too hard I guess.

My site is currently down, but I'll upload the stuff somewhere else later!

Does this one's http module override the gmod one?

Probably not

How would you create a tcp server on a garrysmod game server and have it listen for incoming data but not lock up?

Basically have the garrysmod server realize 'Hey! someone is connecting' at any point in time without the server locking up.

After eight hours of fiddling with this, i can tell you that it works. I have it currently set up for Server 2 Server chat on all my servers. It is much better than a mysql query looking for new text. You are awesome man thanks.

You should do something like :settimeout(0) on the socket, I'm not actually quite sure. See the LuaSocket reference.

This could be usefull for someone that has two dedicated servers and get them to link each other together. Making it even faster to run like an 8 man server

Or use the udp version and send data between servers and run a 128 man server!

This looks too useful for me. Couldn't you upload the files to SpeedyShare or somewhere?

I already uploaded them to garrysmod.org

Edit:

What the hell, seems like the files were deleted...

if you don't mind:

http://neic0.de/gmod/gm_luasocket_rc1.zip
http://neic0.de/gmod/gm_luasocket_source.zip

i think those ones was that files right?

Yep, thanks! Would have had to boot VMware otherwise.

Have fun with that, 128 player deathmatch, and lots of bandwidth consumption.
Not only ridiculously hectic to play in, but also will use a shitload of bandwidth if not optimized fully.

I'm gonna try this module out this weekend if I can, it looks really good for some active communication that I need to do.

Yea, my server starts to stutter if i have 64 in it and they are all firing so i doubt 128 will work. Maybe in a year or so.

This is what I get when trying to load the module.

EDIT: Sorry I hadn't gotten the libraries. Everything works fine so far, however grasping IRC protocol is somehow too difficult for me. All that works is the USER message, nothing else yields a reply.

Here's a small IRC protocol guide:

To connect to the server, port 6667:

USER username . . :The Real Name (appears in whois)
NICK yournick

You should then get a PING somethingrandom, send PONG somethingrandom back

Then you get stuff like

:server.com 001 blahblah, when you get 001 it means you can JOIN channels

use PRIVMSG target :message blah blah to send a message

Hope this helps

If you use mIRC you can also use /debug @foo to open a window that shows all IRC messages being sent/received

Yeah I had it going according to specification, it didn't work out because I had forgotten the \n dar

Servers can't handle 64 players in GMod, nevermind 128.

Mine can. As long as nobody is shooting. You only get minor lag but not really that bad.

I was in one of his servers with 64players in it. It was fun.

I have modified the Lua files to fix the problems with using the sub-modules (socket.http, socket.ftp, etc...).

Required Changes:
Calling require( "socket" ) will load all sub-modules as well.

Fix is available at http://people.msoe.edu/~bogies/luasocket_fix.zip.
Includes only modifications made, simply extract over existing install.

Some folks at Wiremod.com are playing with this, and it seems to be working!
They've been transmitting Wire Values from one server to another!

But for now were testing it out. So far so good!

Keep up the great work!

I got this working on my Garrysmod locally, but unfortunately my dedicated server host doesn't have the VS2008 files, so this doesn't work for me on my hosted server. I was going to re-create a gmod version of HLSW so that I could monitor prop spawns and other garrysmod specific things that aren't sent with the log normally.

Does anyone know how I might go about getting this to work without my host installing the VS2008? Are there any lua files I can add to my garrysmod bin folder or anything?

Also, I saw someone mention an older gm_socket earlier in this thread, but alas I could not find this anywhere.

Thanks :)

You don't need to install VS2008, you just need the latest .dll's. I think with any recent service pack you should already have them.
