Battlefield Vietnam server crash

Battlefield Vietnam server crash

Postby SucceededKiller » Sun Aug 14, 2016 8:03 pm

Hey,

so I'm currently having to deal with a BFV v1.21 server crash from an unhappy former player.

Whatever it does, it makes the process use up 100% CPU and crash as it runs out of resources.

2016-08-14 14:57:51 : Couldn't send message to console! Resource temporarily unavailable (11)

I've gathered what info I can, not sure if it helps but I'll provide it anyway in the hopes it is the right stuff:

tcpdump filtered with wireshark:

His IP is: 188.255.88.81
Our server is 158.69.118.94:15800

Let me know if I've gone wrong somewhere, first time using GDB...

Thanks for any help in advance and let me know if you need anything further.

Hi, this sounds exactly like the old "server crash exploit" that was running rampant on bf42 servers a while ago. Im no expert in reading those logs,

edit: i saw now there was just client files for download, im sure i´ve seen something about patched serverfiles in a thread here

edit2: yeah dead download links, ill see if i can find those files somewhere

Hey,

Thank you. :)

I run 2 servers, a rented main one which, according to our host and previous experience, includes all the community made patches. (He's attacked before, we used their patched binaries and the attacks stopped. He made some comment about how we finally stopped him...) I also have root access to a dedicated one, which is where I grabbed this debug and tcpdump from. Unfortunately, I can't make head nor tails of the hex editing to patch it myself.

If you can find them so I can try those, I'd appreciate it. (Our host wont let me download the patched binaries they provide...but considering it affects that server too, and assuming they are accurate in their statement, this would be a new issue.)

But if not, I am currently talking to Tuia, so with any luck it will be able to be resolved even if you can't find the files. :)

Thanks for any help you can give though! It would be nice to be able to play this game again without the firewall whitelist to prevent him establishing connections....

Regards,

Hi, sorry for late answer, i did search all my disks for those files but with no luck. If you have contact with tuia i think you will be ok as soon he has some time over.

Good luck!

I added 2 of tuia's fixes to moddb as well, if anyone find it useful: http://www.moddb.com/games/battlefield- ... ty-patched
