Many of you want to access your home/office machines from anywhere. you can do this if your ISP gives you public IP, even it is dynamic IP.
All you need is a domain name like “yourname.com” and a dynamic DNS service which maps your dynamic public IP to your domainname. and a dynamic IP update client.
There are many public free/commercial Dynamic DNS servers.
I am using a free dynamic DNS server dnsexit.com
-Register on this server and add you domain name for dynamic DNS service
-In your Domain manager update domain DNS to
ns1.dnsexit.com
ns2.dnsexit.com
-Download a IP update client from http://dnsexit.com/Direct.sv?cmd=ipClients
I am using http://downloads.dnsexit.com/domainUpdate.zip on Linux.
This client is a simple perl script where you have to update it by
adding your dnsexit.com username password domain and your local machine
network interface (eg eth0, ppp0, tun0)
-whenever you connect to internet just execute this script. you can
also add this script in cron to execute it after few hours depending on
your public IP lease time.
-this script will update IP in dnsexit.com DNS for your domain.
-you can also test this from your web browser
http://www.dnsexit.com/RemoteUpdate.sv?login=username&password=password
&host=domain&myip=xxx.xxx.xxx.xxx
you can access all network applications (like remote desktop/ssh/webpages etc)
running on your remote system from your domain.
