It has been brought to my attention that the external IP checker is not working. I have just updated the getip program and getipd daemon to grab external IP from another IP return service. Sorry for all the inconvenience caused. See below for updated files:

Installation and usage of getipd daemon (for most Redhat/Fedora boxes):

If you have root access, you can run getipd daemon as a system daemon by following the below steps

1. Shell into your box as root. Download and save getipd in the "/usr/local/bin" subdirectory on your linux box

3. "cd /usr/local/bin" and "chmod 755 getipd" to make getipd executable

4. Edit (as plain text) /usr/local/bin/getipd to update your DDNS service (DyNS or dnsExit) , username, password, hostname(s), script_dir and update_freq.

* note that the script directory in this case should be set to : my $script_dir="/usr/local/bin/";

5. Download and save gipd daemon startup script in the "/etc/init.d" directory. "chmod 755 gipd"

6. Add gipd as a system service by "chkconfig --add gipd"

* note that I have configured gipd script to run on init levels 3,4 and 5

7. Now you can start, stop, restart or check the status of your gipd service by issuing the below commands:

service gipd start

service gipd stop

service gipd restart

service gipd status

Note: These programs are provided free for your own uses and convenience. I am not responsible for any system failure and loss of data resulting from their use nor do I guarantee that they'll work on your systems.

Installation and usage of command-line getip program:

1. Open a shell terminal and "mkdir ~/bin" to create a ./bin subdirectory in your home directory

2. Save getip in the subdirectory you just created

3. "cd ~/bin" and "chmod 755 getip" to make getip executable

4. Edit (as plain text) getip to edit your DDNS service (DyNS or dnsExit) , username, password and hostname(s) (multiple domains to be separated by ",")

5. Run the script "perl getip" to update your DDNS account

You can run the script as a cron job to update your DDNS account automatically say every half hour or so.
Please read through the script for more information.

Some getip parameters you can use are:

1. "perl getip checkip" (print on screen your current router external IP, no DDNS update performed)

2. "perl getip force" (force DDNS update)

Hope these are useful to you! I can be reached here if you have any comments for me.
