Linux DDOS Patch
Due to increased vulnerabilities of DDOS attacks I have been trying to find a security patch for my named servers that might hopefully help counteract against such as attack.
I am running Red Hat release 7.1 but cannot find anything on the web or RH website. Can anybody help me by recommending a patch that might be useful?
Rgds,

Re: Linux DDOS Patch
redhat 7.1 is very old, but the main question is which version of DNS server do you use ??

Re: Linux DDOS Patch
current bind version is on this web site :
https://www.isc.org/downloadables/11
if i would be in your position, the next step will install a new linux ( centos 5.3 ) with the newest bund in th repository and make a new DNS server activate firewall and open only the most used ports, SSH and DNS.

PS : redhat 7.1 is around 8 years old.

Do a web search for ddos-resistant hosting providers.
