Registering with DynDNS
The first step in giving my server a web-wide recognisable presence given that the ISP allocates the router a Dynamic IP is to register for a free account at DynDNS. This I do and once configured I should be able to reach my Apache website at http://sylvarwolf.homelinux.com. Cool, huh?
Command Shell on Webmin
Back on the server, I type in:
apt-get install ipcheck
Then click on Others>File Manager and navigate to /etc/ppp/ip-up.d/. I create a new file in this directory by clicking New and name it dyndns_update in the requester that pops up. Then paste in the following code:
HOSTNAME=myhostname.dyndns.org cd /root/
if [ -f /root/ipcheck.dat ]; then
ipcheck -r checkip.dyndns.org:8245 $USERNAME $PASSWORD $HOSTNAME
ipcheck --makedat -r checkip.dyndns.org:8245 $USERNAME $PASSWORD $HOSTNAME
replacing “myusername” and “mypassword” with my unique username and password. Also, replace the HOSTNAME field to the domain I have chosen, i.e. sylvarwolf.homelinux.com.
Then back to the Server’s CLI, and I type
chmod 700 /etc/ppp/ip-up.d/dyndns_update
This returned ‘update successful’ for me – more good stuff. Then
apt-get install ddclient The only confusing thing that the install asked me was for the interface that would be used. I guessed that it would be the NIC that my
internet connection was on, so I chose eth0.
Testing the URL
Testing is simple, just type http://sylvarwolf.homelinux.com into my browser and wait. It returns a very boring webpage but one that comes from my server. So Apache is working as well. Yay! All done.
