Packet headers on vps

[xGalardo 11]

Hello! I came across an interesting bug. I uploaded stuff from my home server to a newly purchased VPS, game, db started, runs fine.

However, when I would enter the game, as soon as the character would appear, the client would close (Tested several times). I have collected the following packet errors.

 

0728 14:14:16188 :: Phase Loading does not handle this header (header: 115, last: 1, 115)
0728 14:14:16189 :: Unknown packet header: 64, last: 1 115

0728 14:16:14861 :: Phase Loading does not handle this header (header: 115, last: 1, 115)
0728 14:16:14862 :: Unknown packet header: 101, last: 1 115

0728 14:37:28114 :: Phase Game does not handle this header (header: 130, last: 75, 130)
0728 14:37:28147 :: Unknown packet header: 217, last: 75 130

When the client closes, it almost always complains about another packet error. (There is absolutely no such problem on a hosted server.)

Thanks for the help in advance!

What might also be of interest is that the game, db clang++-devel version is compiled backwards.

First of all, It is because of the vps request's reaction is slower then local host's reaction, and the packet header error occours when the phase is switching faster then the last phase header receiving on the current phase. It is a general bug in the source. The pro solution is fix the input processor swiching on a running request (packet).

Can we have a preview of your VPS configuration ?

Best regards, Florin.

Without a massive overselling, should be fine.

Maybe your provider has maybe problems with networking (packet loss).

Play a little bit and check with this command if u have dropped packets: 

netstat -idb -I <interface>

Sorry for the stupid question, but where do I write this?

In PuTTy, and <interface> can be em0, vtnet0 or something simmilar.

You can ask for network interface name by writting "ifconfig" command on PuTTy.

Could it be <full_duplex>?

It seems better, I have logged out about 30 times, but it still closes the client.
