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. AUTHOR

ldns_pkt_edns() returns true if this packet needs and EDNS rr to be sent. At the moment the only reason is an expected packet size larger than 512 bytes, but for instance dnssec would be a good reason too. packet: the packet to check Returns true if packet needs edns rr ldns_pkt_edns_udp_size() return the packet's edns udp size packet: the packet Returns the size ldns_pkt_edns_extended_rcode() return the packet's edns extended rcode packet: the packet Returns the rcode ldns_pkt_edns_version() return the packet's edns version packet: the packet Returns the version ldns_pkt_edns_z() return the packet's edns z value packet: the packet Returns the z value ldns_pkt_edns_data() return the packet's edns data packet: the packet Returns the data ldns_pkt_set_edns_udp_size() Set the packet's edns udp size packet: the packet s: the size ldns_pkt_set_edns_extended_rcode() Set the packet's edns extended rcode packet: the packet c: the code ldns_pkt_set_edns_version() Set the packet's edns version packet: the packet v: the version ldns_pkt_set_edns_z() Set the packet's edns z value packet: the packet z: the value ldns_pkt_set_edns_data() Set the packet's edns data packet: the packet data: the data AUTHOR
