Any chance that "djbdns" is installed?

Run 'netstat -anp' and look for port 53. The last column will tell you the binary listening on that port.

Please note this command option needs be run by root.

Dan,

Still I am facing the same. Before I post this comment on list, checked everything like named service and bind. No packages of named and bind installed on my server.

The nmap report shows that SOMETHING is already listening on port 53 (note: the error says that the socket for port 53 at address 127.0.0.1 is already in use ... what they mean by "address" would be more clearly written as 127.0.0.1:53 <http://127.0.0.1:53> so as not to confuse you into thinking that ALL of 127.0.0.1 was "in use").


Typically, COS comes with a BIND installation -- so you will need to, at a minimum, turn that off:
*    chkconfig named off ; service named stop*
Then try starting your pdns recursor....


If that solves the problem, then you can get rid of bind altogether (although, there are a number of DNS utilities that I personally like to have, so I personally keep BIND on the server, even if I am running a pdns recursor instead of BIND). Still, if you must, you can remove BIND with:
*    yum erase named*

*
*I hope this helps :)
