# use ex-ipudate to dynamically update your DNS record

## install

```
apt install ez-ipupdate
```
when the package asks you how to configure it, select "manual" to configure it manually.

## configure

head to `/etc/ez-ipupdate`:
```
cd /etc/ez-ipupdate
```
here we will create a file for DynDNS provider, named `dyndns.conf`, with the contents:
```
#!/usr/sbin/ez-ipupdate -c
#
# example config file for ez-ipupdate
#
# this file is actually executable!

service-type=dyndns
user=${username:?}:${password:?}
host=${hostname:?}.alemor.org
interface=wan0
max-interval=2073600

# if you don't use a cache file your dyndns account will probably get banned.
run-as-user=ez-ipupd
cache-file=/var/cache/ez-ipupdate/default-cache

# uncomment this once you have everything working how you want and you are
# ready to have ez-ipupdate running in the background all the time. to stop it
# you can use "killall -QUIT ez-ipupdate" under linux.
#daemon
```
don't forget to make it executable:
```
chmod +x dyndns.conf
```
run it to see if it works:
```
./dyndns.conf
```
once everything is working, uncomment the `daemon` line.
