Command to check DDOS on Server
September 7, 2026
We had an issue where in cPanel server where we had our rDNS settings
were no working. On editing and saving the file from WHM , Rdns worked
Found the issue was due to corrupted named.conf
Below are the steps undertaken to rebuild named.conf
mv /etc/named.conf /etc/named.conf.bak
/usr/local/cpanel/scripts/rebuilddnsconfig
/scripts/restartsrv_named
Now rdns and other records are working fine:)
