Tools for Troubleshooting

Tools for Troubleshooting

BIND includes the always useful dig program, as well as named-checkconf (to check /etc/named.conf for syntax errors) and named-checkzone (to do the same for zone files). We also especially recommend dnswalk and nslint. dnswalk is a Perl script that scans the DNS setup of a given domain for problems. It should be used in conjunction with RFC 1912, which explains most of the problems it detects. nslint, like the analogous lint utility for C programs, searches for common BIND and zone file configuration errors.

By occasionally using these programs to troubleshoot DNS problems (especially after nontrivial zone changes), you go far toward keeping your DNS configuration healthy and trouble free.
