Hey!
My server bumps into me on Linux (100/100mbit)
The server is attacked in the latter days UDP flood.
How is it possible to prevent this?
A firewall is switched on on the server.

is it being attacked by alot of pc's or ips?or one.. if one u could ban the ip by using iptables
Код:
iptables -A INPUT -s <IP> -j DROP
then
Код:
service iptables save
Код:
service iptables restart
that most of the times stops udp flood , and i u dont know the IP ADDRES get TCPDUMP installed in ur linux machine

As RoBo said if you know where the attacks are coming from use IP tables, try blocking all the ports besides the one that hosts you sa-mp server if you already haven't.
