DNSSEC Notes:
|
|
|
|
This file contains description of two interoperabilty problems related
|
|
to DNSSEC that only affect sites using DNSSEC.
|
|
|
|
1. All versions of bind-8 older than 8.2.2
|
|
|
|
Between versions 8.2.1 and 8.2.2 the printed format of SIG records
|
|
changed. As a result, using a signer, named and named-xfer of
|
|
differrent versions will cause parsing errors on signed zonefiles.
|
|
Included is an AWK program that converts old signed zone files to new
|
|
new format, see contrib/dns_signer/add_labels.awk
|
|
Usage: awk -f <path>/contrib/dns_signer/add_labels.awk <signed_zone >fixed_zone
|
|
|
|
2. BIND-8.1 BIND-8.1.1 BIND-8.1.2 Interoperability
|
|
|
|
If you wish to use BIND-8.1.x as a master server (either primary or
|
|
secondary) for DNSSEC signed zone you MUST apply the following patch
|
|
to the file src/bin/named/db_load.c. It fixes a bug that rejects
|
|
valid RSA signatures on load.
|
|
You can patch the file by running following command from this directory
|
|
patch -d bin/named <DNSSEC
