Hello, Nowadays there is alot of DoS Attacks (NOT DDos) some people exploit some things that your cs1.6 server allow to flood your server. For example someone may exploit query requests that help gametracker to know some information about your server to flood your server, They will send alot of packets that will make your server seems it's offline and it's not. Another type of attack maybe aims to flood your server and high all your players pings.
All attacks depend on the UDP port you use for your server. I'am not going to explain more. Anyway these attacks can be stopped using IPTables or outer firewall.
IPTables manage you to drop some specified packets like for example if i need to drop all data packets come from 27020 source port i can do like:
iptables -I INPUT -p udp --sport 27020 -j DROP This will add rule to drop all packets coming from 27020 port.
With iptables you can do many things but first you need to detect how the attacker attacks or which port he uses then you can block his port or you can log some data of his attack and analyze it using Wireshark to know more how this attack works.
IPTables can stop most common DoS attacks nowadays but you need to learn how it's working, That's it and i hope this helps you, If you have any further question just ask.
hello Rahem bro , you can check this man " www.youtube.com/channel/UCOhpLpYnNZn5DWIanOsQWeQ " , this can attack some servers , but i know my friend in morocco have a game server ( Game Power ) , he install the IPtables in his VPS , and it work fine .
First you need to use: ReHLDS/ReGameDLL and all Re works. This will help to block most old exploits which not fixed in HLDS.
Second the attacks you speak about, The flood can be handheld using IPTables but if there is problem that crash the server there is no way else to report it to ReHLDS developers so they fix it simply.
To make more security for your server you after installing ReHLDS install ReAuthChecker to block all kind of fake clients that may flood your server.
Also can you explain how attacks you received seems to be?
i already install ReHLDS , i saw it in your forum and i already install it , ReAuthChecker too , but this is like DoS , need another rule to block all packets . i think Iptables in the last solution .
some haters creat a programes , and that program can attack the server ( Port ) . when he attack the server , all players & server crash ( lost connection ) .that the problem , i think i need to reinstall the server and step ReHLDS ...
yes it get crash and he tell me that he will crash it , after 30 second , i saw the server down , i don't know if i disabled the firewall or something , because i'm using Open Game Panel .
