ldns-test-edns

ldns-test-edns(1)					      General Commands Manual						 ldns-test-edns(1)

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.
