The haeredes package

[ Tags: agpl, dns, program, utils ] [ Propose Tags ]

Haeredes is primarily useful for ISP network administrators. Customers will occasionally decide to switch hosts without alerting the current host; this can cause two problems:

Haeredes can alert administrators when NS/MX records are changed. More detail can be found in the man page.


Make sure has the expected name servers, [ab]

$ haeredes <<< ""

If you use --no-append-root and your nameservers are rooted, you must remember to supply the trailing dot yourself. Otherwise, you'll get false positives.

$ haeredes --no-append-root 
           <<< ""
Domain "" delegates somewhere else: "" ""

Check against the expected name servers, using

$ haeredes --server 
           <<< ""

Check against only one of the expected two nameservers:

$ haeredes <<< ""
Domain "" delegates somewhere else: ""

Check a nonexistent domain (we provide no delegates, since we know .bar will not be delegated):

$ haeredes <<< ""
Domain "" not delegated.
