change bind9 port

[axtoxic107]

Hello,

When i restart my bind9 i face this message

Apr 26 03:01:32 imagezza named[1872]: loading configuration from '/etc/bind/named.conf'
Apr 26 03:01:32 imagezza named[1872]: max open files (1024) is smaller than max sockets (4096)

So i decided to run nmap and see the port 53 in action.
Here are result of it.

PORT     STATE SERVICE    VERSION
21/tcp   open  ftp        ProFTPD 1.3.1
22/tcp   open  ssh         (protocol 2.0)
53/tcp   open  tcpwrapped
80/tcp   open  http       Apache httpd 2.2.9 ((Debian) PHP/5.2.6-1+lenny8 with S                                                                             uhosin-Patch)
3306/tcp open  mysql      MySQL (Host blocked because of too many connections)
5901/tcp open  vnc        VNC (protocol 3.8)
6001/tcp open  X11         (access denied)

So as we cn see 53/tcp port is already open for another process "tcpwrapped"..

How can i change my bind9 to run on another port? I dont know "tcpwrapped" process. So how can i stop it or run it on another port?

Thanks

Can you post the outputs of

netstat -tap

and

netstat -uap

?

Thanks for ur input..

Here are stats of netstat -tap

Here in the above netstat -tap result,
29929/mysqld
tcp 0 0 imagezza.com:46983 vz23.ramhost.us:www ESTABLISHED

This line is confusing to me..ramhost.us is my old host, i create new server on burst.net..

So you're running pdns and bind together?

[axtoxic107]

Actully i first install pdns but its not worked so i install bind and then trying..
Cant i run botht together, do i need to uninstall pdns first?

[dfed]

tcp 0 0 *:domain *:* LISTEN 5551/pdns_server-in

That means pdns is taking up the port on which bind wants to run.

One or the other. either uninstall bind and fix pdns or uninstall pdns.
