Nameserver Checker

  • 772

I've got Bind running on a server and although access to the domains I've set up is correct. I was wondering if there was an online (or offline) tool to check if I had setup the service correctly?

Regards

  1. Bind include a set of tools for testing configuration and zone files. The man pages of named-checkzone and named-checkconf should give you all the informations you may need.

  2. Ask a public recursive server for the records.

    For example, if I just setup some record for randomtest.example.com on my server that's authoritative for example.com,

    host -t any randomtest.example.com. [8.8.8.8][1]

    will tell me if it is getting out to other nameservers on the internet.

  6. You can issue direct queries to your server using host/dig to test Bind configuration:

    host -t soa yourdomain.com server_ip # fetch SOA record
host -t ns yourdomain.com server_ip  # fetch NS records
host -t mx yourdomain.com server_ip  # fetch MX records
host yourdomain.com                  # fetch A record

    or just

    host -t any yourdomain.com server_ip # fetch all

    I do recommend you to run tests from another machine to detect problems with firewall, interface binding, etc. If you don't want to muck with command line just use one of the online tools.

    http://www.dnsinspect.com it's an another online DNS testing tool.
