  1. Tinydns issues

    Hey gang,

    Here is the issue im having:

    I installed Tinydns on RHEL ES4. Everything was fine. This morning I
    saw that my dns server is not accepting queries on port 53. Netstat
    shows the follwing:

    udp 0 0 :53
    0.0.0.0:* 5652/tinydns


    svstat shows tinydns running, and no errors on the multilog.

    when I do a "telnet localhost 53" it does not even make a socket
    connection.
    Any ideas?

    Thanks in advanced

    telnet uses TCP, not UDP. UDP is not a connection oriented
    transport protocol. DNS general works over UDP but can also work
    over TCP. Your Tinydns may be configured to only use UDP (which
    is fine).

    Also, your netstat shows that tinydns is listening on the
    interface, not on the loopback interface (127.0.0.1, or ::1), so
    trying to contact "localhost" won't help.
