    Hello,

    When i restart my bind9 i face this message

    Code:
    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)

    Apr 26 03:01:32 imagezza named[1872]: creating IPv4 interface venet0:0 failed; interface ignored
    Apr 26 03:01:32 imagezza named[1872]: listening on IPv4 interface venet0:1, 184.82.19.179#53

    Apr 26 03:01:32 imagezza named[1872]: creating IPv4 interface venet0:1 failed; interface ignored
    So i decided to run nmap and see the port 53 in action.
    Here are result of it.

    Code:
    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
    Code:
    netstat -tap
    and
    Code:
    netstat -uap
    ?

    Thanks for ur input..

    Here are stats of netstat -tap


    Netstat - uap

    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?

    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?

    Code:
    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.

    i am trying my best here..
    My latest nmap result
    mysql open but the message "Host blocked because of too many connections" there must be something wrong in the server so it blocked it..

    Where can i see the error log of mysql..I am using debian linux..

    And one more result for ur reference - netstat -tap
    What does "bind-redirect 127.0.0.1" do? Right now in my my.cnf file that line is commented.

    One more important thing, my phpmyadmin working well here..I have install mysql by following below tutorial
    http://www.howtoforge.com/ubuntu_debian_lamp_server

    Thanks

    You can try to add something like
    Code:
    max_connections        = 100
    to the [mysqld] section in /etc/mysql/my.cnf. Don't forget to restart MySQL afterwards.
