No-IP

No-IP Provides a Dynamic Update Client (DUC).

Download it, extract it, make, sudo make install.

The install requests credentials that are stored in /usr/local/etc/no-ip2.conf.

Reconfiguration can be done via:

/usr/local/bin/noip2 -C

The DUC has a traditional init.d script, but can be managed with systemd.

Stop and start the service with:

sudo systemctl stop noip2
sudo systemctl start noip2
