Survive from DDoS
Dear all,
yesterday, our shell server was attack and server immeditiately reboot.
I checked logs, it likes UDP flood with destination port 53. Is there
any way how to survive from this kind attack? Also, is there any
url/resources to improve our shell
the packets to the specified port.
Regards,
Ivailo Tanusheff

Dear Ivailo,
thank you for your response. I am using ipfw to limit all packets for
all open port in my server. But the packet size was 600 Mbps which could
not filtered by our ISP.
