ULTIMATE PING/CRASH/LAGS BY 1 CHAR !

[Saint Spear]

Hello Everyone , Im tired as fuck , didnt even sleep tongiht , Im working for 7-8 months for my Retro Custom Evolution OT , yesterday was launch day , 30 minutes before OT open Sebastian Rasmusson Admin of Frozeria told me he will destroy my ot cuz its shitty and he says too that I stole all things from him which is Incorrect. Lets get to beggin , I bought hosting service from Don Daniello 4 GB rams , around 50+ Euros, Im using TFS 0.4 REV 3777 Tibia client 8.60
Allright so time for server launch came, after i wrote /openserver automatic was like 10-15 players and starting grow up till 25. After that Ultimate lags begin and I didnt know what to do , I was angry as fuck, I thought its a DDos attack but i knew its DDos protected so ... Sent a few messages to my hoster Don Daniello , He reply me few hours later with message

"I checked the network graphs and incoming traffic did not exceed 10 mbps today. This is not network DDoS for which you are protected. It's most likely that the attacker is abusing some weakness in your engine and slows it down, most likely by running a script that is depositing thousands of items in a house, depot or backpack. These are known attacks and you are using old source that may be vulnerable."

This morning I thought like let me open it maybe some errors will be in console I wrote /openserver , RIGHT 5 SECONDS AFTER IT an guy get in-ot , His name is Mr Habahaba , After his login Ultimate lags begin , hes doing something that abuse mine ot probably ping or something like that which makes big lags, I copy his IP Adress and found hes from Sweden, Region Skane Lan , City Malmö, Postal code 217 49 , I Thought if i get into Account that i can see what is he right doing so i can fix it, I went there and saw nothing Special, Normal starter items , hes probably using some kinds of program or similar , Sebastian on facebook told me its C++ and he told me Im stupid for making OTs or similar, Also he threatens me like I will find all info about you , I got mafia in your Country , I will pay 10k Euros for Each member of your family. He's sick. If anyone of you know How I can fix this problem Please help me ! Thanks.

Are you sure he does it with his own char? Sometimes he can tell that he is doing it, but it can actually be some friend who is causing the lag. It can be a attack ddos too, you have to check if you are getting attacks by your screen, notice if your putty/filezila (or other app) is slow too. Check where the player is when the lag runs, check talkactions. How is your config.lua in the packets part per second, have it there? Put max 40

Maybe since it’s old it has some vulnerability in the source. You could perhaps use, [8.60] The Forgotten Server 1.2

It you take you some time to convert some of your scripts to TFS 1.2

after i do /openserver only 1 char cames , I tried to delete talkactions and openserver but still doings something strange.. also I tried to move him some sqms or somewhere but dont changes anything, Also what do you right means with packets part per second ?

Transferting to 1.2 is nice move but ... All my scripts need to be updated, Im not that good to update all them , theres a tons !

Hello there,

The problem here is that you're using content from other people, if you've made everything yourself you'd know where the weaknesses are. Just log every action from the player that crashes your distribution...

Kindest Regards,

Have you private tested your own server, just incase there is something wrong with it?

otsmanager does not have sudo privileges once in root run apt-get you don't need to use sudo because your permissions are already elevated.

It looks like your dedicated server uses OVH's custom kernel. This may very well be inconvenient for you, but you most likely will have to reinstall the OS (and while doing so, you should select Use default kernel).

I really dont want to make bigger problem, Ill better wait for Don Daniello.

I don't know how this was in old tfs, but to me it looks like packet spamming, you got not limit (my guess) for incoming packets and he is just flooding your server somehow with something. TFS 1.x is kicking players who are sending more than maximum packet per second rate.

When lagging, execute in your screen these commands below and post the log/print here

netstat -plan|grep :80|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -n
netstat -plan|grep :7172|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -n
