go-nsupdate

Update dynamic DNS records from netlink.

go-nsupdate reads interface addresses from netlink, updating on ip link up/down and ip addr add/del events.

The set of active interface IPv4/IPv6 addresses is used to send DNS UPDATE requests to the primary NS for a DNS zone.

Install

go get -v github.com/qmsk/go-nsupdate

Usage

TSIG_SECRET=... go-nsupdate --interface=vlan-wan --tsig-algorithm=hmac-sha256 yzzrt.dyn.qmsk.net --watch
