    My problem is that I can't import dns zone by axfr to my slave Bind from MyDNS master.

    When I type in my slave:

    everything is ok, but when it'ss trying to sync (by axfr :


    I get error

    I've also noticed that MyDNS can't bind to port #53 (I run:

    ) Is it the reason ?

    Everything worked, but i had to reinstall all master : /

    If mydns cant bind toport 53, then you must ahve another dns server installed on your system. Stop this other dns server and then start mydns.

    mydns -v says:
    mydns[12383]: ipv4_listener: bind on socket 6 (TCP) failed: Address is already in use
    but in netstat -tap I cant see any port 53 ! : /

    I have also to say that I have a problem with internal DNS settings, it means that after installation without internet cable plugged in I couldnt browse the internet, I installed package resolvconf and it started working, yesterday I unistall it and everything is working fine (i didnt restart machine)


    I also used this fix:

    Then you have still the resolveconf running. Resolving wills top working as soon as you restart the server. So you should reinstall the resolver, configure it to listen only on ip and then edit the mydns.conf file and configure it to listen on all ip addresses except

    where i can configure it ?

    Is it the only reason of this problem? I checked that on old master was same problem but axfr worked :/

    Is it ok if i have my public ip as my nameserver (/etc/network/interfaces)? Maybe I should type ?

    What's the output of
    netstat -tap
    ? What's in /etc/mydns.conf?

    web:~# netstat -tap

    netstat -ltnp | grep :53


    so maybe everything is ok?
    Is it possible that I done mistake in axfr.c fix but MyDNS started ? Can I reinstall MyDNS without reinstalling ISPConfig3 (=reinstalling system) ?

    As far as I can see, MyDNS is listening on all IP addresses. If you don't want it to listen on, you should explicitly list your other IP addresses in the
    listen =
    line in /etc/mydns.conf and restart MyDNS.
