Insall cache only powerdns server Rumi, September 4, 2011 I decided to install another caching dns server , after some research I found PowerDNS. it uses MySQL for storing its zones , but hopefully its caching component doesnt need mysql , so great , lets go and install it. My favourite OS is debian lenny , so I ran the following command : 1 apt-get install pdns-recursor WOW , it was very simple ! it is already working on localhost , but I needed it to listen on all IPs on my box and accept queries from everyone I wanted to serve public :p so I went to /etc/powerdns and opened “recursor.conf” file and made the following changes : 1 allow-from= 2 local-address=0.0.0.0 and restarted the service by : 1 /etc/init.d/pdns-recursor restart it’s done now it is working as a public caching name server.
