Are you using the latest Patch Level (currently Patch Level 18)?

 

[Exmerus]

Yes i just updated 2 days ago before he start crashing it.
Maybe should i Update my server to 0.3? Or just w8 the final relase of TFS 0.3 comes because i can just set "stop" to my dedicated and the days won't be consumed but i preffer to keep it online if you can help me i will be very happy.

You should use what talaturen said to you indeed, but TFS should be pretty stable against crash-attacks, or if he's DDoS attacking you? If you'd have telling more specific about the case, I could have answered your question. :<

It is like the server is running already for 3 month but this guy log on server and message me. He just tell me look how i crash your ot server. 5 secs later (without any lag) server crashed. Then he logged in and he told me items now and i banned his ip. And 10 secs later my server crashed and he logged again and continue asking for items. He told me he is a "hacker" and he has a program. Idk Whats happenning.

put exception tracker on

TRACER* Ryan, tracer, not tracker.
Also, on Linux its enough to use gdb

 

[Doonrak]

btw check out guildsystem the !promote thingy might crash your serv.

I experienced this as well.

I run Arya, a 250+ player stable realmap OT.

Today people went and crashed it all day to dupe items.

I reverted back to revision 12.

Just so you know this is not an isolated incident.

And yes, I had just updated to revision 18.

 

[Tprocheira]

Very Strange...
Try using a tracer as Ryan said, or, try to get a Linux dedicated and install gdb (thanks to Elf )
Why don't your try to check what he's position is (if he's not right in front of you), it might be a problem with a script or in the map...
Anyways, good luck.

Yours, Tprocheira

Crash is why have bug in site, one people create character with sex 5 or more, and TFS don't accept and crash.

Potential fix:

Go to tools.cpp->

uint32_t adlerChecksum(uint8_t *data, size_t length)
{
	[b]if(length > 30000)
		return 0;[/b] //won't let players spoof 30000+ bytes in a packet
	const uint16_t adler = 65521;
	uint32_t a = 1, b = 0;
	while (length > 0)
	{
		size_t tmp = length > 5552 ? 5552 : length;
		length -= tmp;
		do
		{
			a += *data++;
			b += a;
		}
		while(--tmp);

		a %= adler;
		b %= adler;
	}
	return (b << 16) | a;
}

Going to test it in a bit, but yea. Credits to a player who reported it to me. Note, this bug is in all 8.31 OTS, so if this is indeed the cause, then I would put it in SVN immediately so most OT owners are not vulnerable to this now public bug.

Yea! It works for me! Great job codemaster2!
