|
|
- Debug a DNS pathway for a Fully Qualified Domain Name (FQDN):
|
||
|
|
|
||
|
|
`dnswalk {{domain}}.`
|
||
|
|
|
||
|
|
- Process sub-domains [r]ecursively:
|
||
|
|
|
||
|
|
`dnswalk -r {{domain}}.`
|
||
|
|
|
||
|
|
- Only perform a `dnswalk` if the zone has been [m]odified since the last run:
|
||
|
|
|
||
|
|
`dnswalk -m {{domain}}.`
|
||
|
|
|
||
|
|
- Print [d]ebugging and status information to `stderr` instead of `stdout`:
|
||
|
|
|
||
|
|
`dnswalk -d {{domain}}.`
|
||
|
|
|
||
|
|
- Suppress the check for [i]nvalid characters in the domain name:
|
||
|
|
|
||
|
|
`dnswalk -i {{domain}}.`
|
||
|
|
|
||
|
|
- Enable duplicate A record warnings:
|
||
|
|
|
||
|
|
`dnswalk -a {{domain}}.`
|
||
|
|
|
||
|
|
- Enable "[F]ascist checking" to compare the A record PTR name with the forward name and report mismatches:
|
||
|
|
|
||
|
|
`dnswalk -F {{domain}}.`
|
||
|
|
|
||
|
|
- Enable "[l]ame delegation" to test whether the listed host is returning authoritative answers:
|
||
|
|
|
||
|
|
`dnswalk -l {{domain}}.`
