Could Not Read Rdata Syntax Error

Google has been quite unhelpful, hence my appeal to this list. > Well, RDATA is kind of a fundamental part of DNS. It's the "payload" of any given Resource Record. For instance, the RDATA of an A (address) record is the address itself, the RDATA of an MX (Mail eXchanger) record is a combination of the name of a mail server and the relative preference which it should be given among all of the mail servers for the domain name. Different record types have different RDATA structures, so it's not that easy to generalize. Looks like you flubbed the syntax for your nsupdate prereq or update commands, e.g. an improperly formatted address for an A-record update, a missing preference value for an MX-record update, the wrong number of fields for an SOA record, or non-numeric where only numeric was expected. Something like that. - Kevin Next message: Impact of having loghost defined in DNS...?

DynDNS.org (which obviously was a smart decision since they now pretty much closed their free service) so I rolled my own… What you need is the following: Host your domain yourself using the popular nameserver "Bind." Host a small CGI script that will tell you your external IP (or use one of the many free services available that do the same). Run a machine within your LAN 24×7 which can detect changes of your external IP and update your hostname accordingly.

This allows resource records to be added http://linuxcommand.org/man_pages/nsupdate8.html or removed from a zone without manually editing the zone file. A single https://forum.pfsense.org/index.php?topic=97205.0 update request can contain requests to add or remove more than one resource record. Zones that are under dynamic control via nsupdate or a DHCP server should not be edited by hand. Manual edits could conflict with dynamic updates and cause data to be lost. The resource records that are dynamically added or could not removed with nsup- date have to be in the same zone. Requests are sent to the zone’s mas- ter server. This is identified by the MNAME field of the zone’s SOA record. The -d option makes nsupdate operate in debug mode. This provides tracing information about the update requests that are made and the replies received from the name server. Transaction signatures can be used to authenticate could not read the Dynamic DNS updates. These use the TSIG resource record type described in RFC2845 or the SIG(0) record described in RFC3535 and RFC2931. TSIG relies on a shared secret that should only be known to nsupdate and the name server. Currently, the only supported encryption algorithm for TSIG is HMAC-MD5, which is defined in RFC 2104. Once other algorithms are defined for TSIG, applications will need to ensure they select the appropriate algorithm as well as the key when authenticating each other. For instance suitable key and server statements would be added to /etc/named.conf so that the name server can associate the appropri- ate secret key and algorithm with the IP address of the client applica- tion that will be using TSIG authentication. SIG(0) uses public key cryptography. To use a SIG(0) key, the public key must be stored in a KEY record in a zone served by the name server. nsupdate does not read /etc/named.conf. nsupdate uses the -y or -k option (with an HMAC-MD5 key) to provide the shared secret needed to generate a TSIG record for authenticating Dynamic DNS update requests. These options are mutually exclusive. With the -k option, nsupdate reads the shared secret fails to start with DNSSEC enabled « previous next » Print Pages: [1] Go Down Author Topic: 2.2.4 with unbound fails to start with DNSSEC enabled (Read 579 times) 0 Members and 1 Guest are viewing this topic. xbipin Hero Member Posts: 1531 Karma: +4/-0 2.2.4 with unbound fails to start with DNSSEC enabled « on: July 28, 2015, 07:44:59 am » im getting these issues with unbound on 2.2.4 on a full install and noticed no DNS resolution happens when in forwarding mode and DNSSEC support enabled, unticked that and saved and it starts to work fine againCode: [Select]Jul 28 18:08:55 unbound: [60120:0] notice: init module 0: validator
