    I am having an odd problem with sites not loading up. It looks to be DNS or sub-interface related.


    DNS Report for thedomain.com


    Parent pass NS records at parent servers Your NS records at the parent servers are:

    ns1-web01.domain.com. [ 209.55.123.45 ]
    ns2-web01.domain.com. [ 209.55.123.46 ]
    [These were obtained from k.gtld-servers.net.]
    pass Glue at parent nameservers Parent nameservers (I checked with k.gtld-servers.net.) know A record for your domain, Very good !
    NS info NS records at your nameservers Your NS records at your nameservers are:

    209.55.123.45 Does not respond

    209.55.123.46 Does not respond
    pass Mismatched glue OK. The DNS report did not detect any discrepancies between the glue provided by the parent servers and that provided by your authoritative DNS servers.
    pass No NS A records at nameservers OK. Your nameservers do include corresponding A records when asked for your NS records. This ensures that your DNS servers know the A records corresponding to all your NS records.
    fail All nameservers report identical NS records ERROR. The NS records at all your nameservers are different, check the info above for details.
    fail All nameservers respond ERROR: some nameservers does not respond
    ns2-web01.domain.com. [209.55.123.46] does not respond


    I have performed:

    cd /etc/sysconfig/network-scripts
    chkconfig --levels 345 network on
    service network restart
    /etc/init.d/ipaliases start
    /sbin/ifconfig -a

    Everything looks great there.


    /etc/init.d/named restart

    restarts fine.

    service named status

    debug level: 0
    xfers running: 0

    Looks like the latest CSF update caused the issue. Removing it and rebuilding it corrected the issue.
