    Hi!
    Following problem:

    Since I think yesterday or the day before my auth DNS server ns1.bitworx.cloud (according to the Perfect Multiserver-Setup by Th0m) seems no to answer public dns requests.
    I tried via some web services (e.g. https://dnschecker.org/domain-health-checker.php?query=tanzsportclub.at ) or via dig from one of my other servers in another net, not connected to the internal net of my ispconfig-setup.

    Setup:
    host.bitworx.cloud (web,db,panel,mx,...) : 10.0.0.1
    ns1.bitworx.cloud (ns1 auth) : 10.0.0.2
    ns2.bitworx.cloud (ns2 slave -> not set as slave in ispconfig as Th0m stated to do the slave zones manually) : 10.0.0.3

    Master and Slave DNS settings for tanzsportclub.at

    If you do
    Code:
    dig any tanzsportclub.at
    it responds:

    It seems they do not correctly sync
    Maybe you have some ideas for me as I am not a pro in BIND thingys ;-)

    If they do answer when querying from the same subnet, my first quess is firewall prevents public queries from reaching the servers.
    My signature has link to DNS tutorial with info on troubleshooting dns servers.
    Is the only difference between your two test outputs the display of DNSSEC information?

    Hi!

    Thanks for the fast reply.
    I think there is also a problem with the authoritative dns server.
    DNS requests are handled well from outside - so i dont think theres a firewall problem - or do you think its internal?

    I will look into your signature when I‘m home.

    Restart bind on both servers and then check /var/log/syslog for errors regarding bind / named.

    Hi Till!
    :edit
    I did as you advised and the problem seems to be gone.


    @Taleman
    I looked into your tut and I think I did nothing wrong so far, it already worked until a few days ago...
