    DNS Problem...

    One of my domains is playing up ! I have check the registrar and the nameservers are correct.

    I have logged into WHM and check the dns config for the domain and everything seems fine.

    I have check the unresolved address and the site is still there but the problem is when I go to the domain....it trys to look for "http" and then goes straight to google (using firefox) and fails...

    I have checked whois.sc and the error which shows up when the site tries to resolve the domain is as follows:

    500 Can't connect to http::80 (Bad hostname 'http:')
    Please help......

    Thanks

    What's the domain? Plug it into dnsreport.com and see what it says.

    Well this should get you fixed up, at least knowing what the problem is.

    # rndc reload

    # tail -100 /var/log/messages (look for any errors in the zone reload)

    # dig @localhost domain.com

    Ping domain.com from your pc, is it the correct IP?

    and finally, check /usr/local/apache/conf/httpd.conf for the domain.com and make sure the vhost container is setup on that IP.

    Post the results if you get stuck.

    Okay, I have swapped the IP's in the domain registrar....so it is now as follows:

    Your NS records at the parent servers are:

    ns1.deltrumweb.com. [80.175.30.188] [TTL=172800] [GB]
    ns2.deltrumweb.com. [80.175.30.85] [TTL=172800] [GB]

    However, I am still getting the following probs...

    ERROR: Your nameservers report glue that is different from what the parent servers report. This will cause DNS servers to get confused; some may go to the IP provided by the parent servers, while others may get to the ones provided by your authoritative DNS servers. Problem record(s) are:

    ns2.deltrumweb.com.:
    Parent server (f.gtld-servers.net) says A record is 80.175.30.85, but
    authoritative DNS server (80.175.30.188) says it is 80.175.30.188
    ns2.deltrumweb.com.:

    To correct the ns1.deltrumweb.com zone, you might, if you don't see it within your edit dns zone.

    The zone for your domain you can edit within whm, the A records for the dns name servers could just be in there, with no additional need for seperate zones for ns1 + ns2 - probably best to contact your support and have them straighten things out I'd say

    I have amended th A record for ns2 and there appears to be no problem resolving...

    Your NS records at the parent servers are:

    ns1.deltrumweb.com. [80.175.30.188] [TTL=172800] [GB]
    ns2.deltrumweb.com. [80.175.30.85] [TTL=172800] [GB]
    [These were obtained from f.gtld-servers.net]

    Your NS records at your nameservers are:

    ns2.deltrumweb.com. [80.175.30.85] [TTL=14400]
    ns1.deltrumweb.com. [80.175.30.188] [TTL=14400]

    However, I am still receiving one problem.....

    ddlteam.com is an account on my this account but it is still not resolving ????

    You need to remove the IP + NS record

    deltrumweb.com. 14400 IN NS 80.175.30.188

    That is an incorrect NS value.

    Steve,

    I have sorted the problem.....My customer placed an incorrect redirect in cpanel ! Then complained of dns errors.....which when I checked out their theory gave me dns errors which threw me off the scent totally !

    Cheers for your help mate

    No worries, we got rid of that spurious NS record along the way.

    Just goes to prove that you have to look further than your nose when receiving a problem in a ticket

    Have a good one
