dyndns is a service that allows you to access your computer under a static name. For example your home computer could have the address mycomputer.dyndns.org. Even if your home computer's IP changed, you would still be able to access it via the public internet. To get this, you will need
- an account at http://www.dyndns.org
- a daemon ddclient running on your computer
This article describes how you get a daemon running on your computer. It is written to fit SUSE Linux 11.4, but other distributions should work same or similar. Download ddclient like this:
yast -i subversion svn co https://ddclient.svn.sourceforge.net/svnroot/ddclient/trunk ddclient
Create a folder for ddclient to cache data:
mkdir /var/cache/ddclient
Create a folder for ddclient's configuration
mkdir /etc/ddclient
Configure it by editing /etc/ddclient/ddclient.conf:
protocol=dyndns2 use=web login=yourusername password=yourpassword yourhostname.dyndns.org
Now edit the crontab to contain a call to dyndns and restart cron.
SHELL=/bin/sh PATH=/usr/bin:/usr/sbin:/sbin:/bin:/usr/lib/news/bin MAILTO=root # # check scripts in cron.hourly, cron.daily, cron.weekly, and cron.monthly # -*/15 * * * * root test -x /usr/lib/cron/run-crons && /usr/lib/cron/run-crons >/dev/null 2>&1 5 * * * * root /root/ddclient/ddclient
