GeoB99 iptables -A INPUT -p udp -m length --length 0:28 -j DROP
Install Anti-DDoS on linux vps BcY: Thanks, i'll try it 
sudo apt-get install tcpdump
tcpdump -i eth0.
Server Auto Restart script [LINUX/VPS] (solved), Nekomata gave a very detailed tutorial on how to set up. Nekomata. thanks @ GeoB99.topor - with fancy colors -
htop(needs to be installed first)

Rygna: Normally the dedicated server should not take much RAM unless your computer is really old although I highly doubt as you run Ubuntu 16.04. You can check the RAM usage of processes with topcommand anyway. Note the RAM usage of a process is denoted as %MEM (Memory Usage in Percentage) and %CPU (CPU Activity in Percentage).
Hajt method~ Hajt: why he should use google dns servers? 
BcY: Hmm because google's ip is set in script above, also these dns are pretty fast and so far it works without any problems on my virtual servers. Hajt: i got it. Also is it possible to use it without dns? gotya2 said. I have a python script for that (it also checks if the server is using too much memory) but you'll have to wait a bit if you want it. BcY: Yes, that part of the script isn't mandatory Hajt: this script is enough to protect against ddos? cuz I'm paying too much money for anti-ddos on my vps. lol mrc: Anti-ddos protection doesn't work because it is problem related to CS2D. You can flood the game server with low number of packets. I was able to DDoS @ Yates's dedicated server which had pretty strong anti-ddos protection in OVH so you know. These rules works against free ip stresser services. Quattro: The day that happens is the day that @ Pagyra stops saying standart. Quattro: Why did you say that? No one said that is pro hacker, also I'm pretty sure everyone of us know difference between DoS and DDoS attacks. 1
