dyndns-refresh
==============
a small bash-script to refresh a `dyn A` entry. Should work for many providers.
features
--------
- simple bash-script (you don't have to install a program)
- logging (the response of the provider will be logged)
usage
-----
- clone the repository (for example in your home directory) and make [`dyndns.sh`](dyndns.sh) executeable
```bash
git clone https://github.com/sedrubal/dyndns-refresh.git && cd dyndns-refresh
chmod +x dyndns.sh
```
- copy the [`config.cfg.example`](config.cfg.example) to `config.cfg` and edit it. You only have not to provide every variable:
```bash
cp config.cfg.example config.cfg
editor config.cfg
# provide following configs:
# - $url
# - $loggerpath
# - $logfile
```
- set file permissions:
```bash
sudo chown -R $USER:$GROUP .
sudo chmod 400 config.cfg
```
- check, if the script works
```bash
./dyndns.sh -v
tail $logfile
```
- create a crontab (`crontab -e -u $USER`) like this:
```bash
0/15 * * * * /home/$USER/dyndns.sh 2>&1
# │ └─┴─┴─┴─ every hour, day, month, weekday
# └────────── when minute == 15
```
functionality
-------------
- a crontab will trigger this script (default: every 15 minutes; you can change the interval)
- this scripts uses `curl` to request the update-website of the provider. He will notice your ip.
- the output will be saved as log
dependencies
------------
- unix based os
- curl
- cron
- logger
- (logrotate)
supported providers
-------------------
- joker.com
- no-ip.com ?
- ...
not implemented yet / todo
--------------------------
- (automatic installation and support for crontab)
- check if parameter $1 == "-v" (bash is so complicated)
