Internal host lookup fails

    I used the MyDNS with MyDNSConfig Control Panel and DNSMasq on Ubuntu 6.10 tutorial to install Mydns and dnsmasq.

    dnsmasq is listening on 127.0.0.1 and external requests are being forwarded there but my internal requests are not getting any where.

    If I ping the nameserver from a host on the LAN it is failing but if a ping externally the resolver is passing on the address.

    I am not sure where I am going wrong.

    Lan requests are directed to the right IP addss in DHCP settings so I am at a loss.

    Could anyone help me to wade through this mess?

    What's in your /etc/resolv.conf?

    Search home.internal
    nameserver 127.0.0.1
    nameserver 192.168.2.66 (ip of mydns)

    so far the dnsmasq seems to be querying the root servers directly for dns queries. As far as I can tell the local mysql mydns table does not recognize the home.internal domain and is passing the query directly to the resolver.

    :confused:

    Please try to set in resolv.conf only this one line:

    nameserver 192.168.2.66

    normally mydns should pass every dns query it is not able to answer to the dnsmasq server itself.

    I made the change you suggested and restarted networking

    Here are the results of an internal dig. Looking to the root server.

    You are sure that you have a SOA created for home.internal in mydns that works from all other IP addresses except from the local IP?
