Did you try to use the updated core.so file included in the Linuxfix directory?

[}TCP{Carnage]

Be sure to upload .u / utx / usx and map file in binary mode with ftp
and .ini and other text based files in ascii
I also have several linux servers running various games and if i do it incorrectly i also get segmentation faults.

Might be worth a try

Hello All!

Yesterday during a rumble our server crashed a lot of time, its the first time this happened!

How can i know if its a players crashed our server or if it was another problem from our provider?

before installing this mod i prefer understand well.

ty in advance.

Regards

[qwerty]

any updates coming out for this? these douche bag hacks are still able to crash a server with a snap of their finger

[AnthraX]

I will update this whenever there's a new server crasher out. The person who wrote the previous crash tools hasn't released anything since ServerCrashFix so either you're running a vulnerable mod or someone else wrote a new tool. Do you have any server logs that show the crash?

ServerCrashFix is a mod that will protect your server against servercrash/DoS
exploits that were released after the latest UTPG patch (v451).

In particular it will protect you against these exploits:
* Malformed String Exploits
* Fake Player DoS
* Malformed Join Request DoS

Whenever a player attempts to crash the server, ServerCrashFix will temporarily
blacklist the player's ip so all further requests from that IP will be ignored
until the end of the map.

ServerCrashFix replaces the earlier patches implemented in AnthChecker v1.38.
When ServerCrashFix is installed on a server with AC v1.38, it will disable AC's
patches and use it's own.

ServerCrashFix works on both Linux servers and Windows servers although some
Linux admins might have to update their server's Core.so file with the one
included in the LinuxFix folder of this package.

AnThRaX u the man , downloading now. Check messages bro , you should have a few

[SoNY_scarface]

No one is crashing your server. It is a mod that you have installed on there that is encountering a sigmentation fault.

[AnthraX]

most likely nexgen. Try removing it and see if it still crashes. I've told defrost what's causing the crash and how he can fix it so I think the next version will no longer cause this crash (?)

[qwerty]

omg ty ty I wasn't sure

[SoNY_scarface]

I am using nexgen111 and it is fine. Maybe try a stock server and see if the server crashes. If it does, then its not mod related. If it doesn't, then it is

Try a stock server and nexgen to rule out any problems with nexgen.

[qwerty]

its just weird.. it crashes mostly when i kicked this player who tried changin his ip to join my server once he couldn't join he used a proxy i banned the proxies and all of a sudden the server crashes and it will crash 2-4 times. then it wont crash any more at all until the same time the next day.. call me crazy but i think something is up.

[face]

At qwerty when i made a linux server with so many actors and packages i had same problem as you.
I fixed it with 1 small thing you can try it out.

See this:
ServerActors=IpServer.UdpServerUplink MasterServerAddress=unreal.epicgames.com MasterServerPort=27900
ServerActors=IpServer.UdpServerUplink MasterServerAddress=master0.gamespy.com MasterServerPort=27900
ServerActors=IpServer.UdpServerUplink MasterServerAddress=master.qtracker.com MasterServerPort=27900

Should look like this and 1 or 2 more changes in your ini:

[Engine.GameEngine]
CacheSizeMegs=128
UseSound=True
ServerActors=IpDrv.UdpBeacon
ServerActors=SecureValidate.SVUdpServerQuery
ServerActors=SecureValidate.SVUdpServerUplink MasterServerAddress=unreal.epicgames.com MasterServerPort=27900
ServerActors=SecureValidate.SVUdpServerUplink MasterServerAddress=master0.gamespy.com MasterServerPort=27900


I miss something there!
1 to many masterservers make it 2 lines and then i miss securevalidate.
I can crash your server without being on it just from my pc with your server ip.

Its well known by many people that they can boompacket your queryport!

Anyway try it it might help ya.

Face

dl link: http://ut-files.com/index.php?dir=An...ecureValidate/

ps make sure to read the readme.

[qwerty]

thanks face! I will give this a try.
