PROGRAM:

NAME


ldns-test-edns - test if dns cache supports EDNS and DNSSEC.

SYNOPSIS


ldns-test-edns [ -i ] { ip }

DESCRIPTION


ldns-test-edns tests a DNS cache and checks if it supports EDNS0 and DNSSEC types so that
it can be used as a dnssec-enabled DNS cache. It sends two queries to the cache, one for
the root key and one for a DS record. These must succeed, the answer must have EDNS, that
type and signatures.

If the IP address is good for DNSSEC, it is printed with 'OK'. Otherwise short
description is given of the failure. If OK is given, the cache should be good to use as a
cache for a local configured DNSSEC validator.

The tool assumes the root is signed and Sweden is signed. Also, the queries are sent with
the CD flag, the tool does not check that the results are validated, but that they can be
validated.

OPTIONS


-i option enables a mode where the working IP addresses are printed after another, with no
other explanations, and if none work or no IP addresses are on the input, 'off' is
printed.

ldns-test-edns takes one or more IP addresses, it checks them in turn. IPv4 and IPv6
addresses can be given. The exit value is for the last checked IP address: 0 is OK, 1 is
failure, 2 is some sort of network failure.
