With access to Skys router
The DG834GT management interface offers a debug option that enables the embedded Telnet server. To do this, fire up your web browser and enter the following URL (changing the IP address to your router’s address if necessary):
http://192.168.0.1/setup.cgi?todo=debug
You’ll be asked for the administration username/password (‘admin’ and ‘password’ on a normal DG834GT though I understand this to be ‘admin’ and ‘sky’ on Sky’s branded version). With any luck you’ll then see the message “Debug Enabled!”.
You should now be able to connect to the router via Telnet by entering the following command at the Command Prompt:
telnet 192.168.0.1
If all goes to plan, you should then see the following:
BusyBox v1.00 (2005.07.29-07:22+0000) Built-in shell (ash) Enter 'help' for a list of built-in commands. #
In which case, well done. You’re now logged in directly to your router.
The DG834GT stores all of its settings in one file. To search this file for the ADSL login details, enter the following command at the BusyBox prompt:
cat /tmp/nvram | grep pppoa_
You should then see something like this:
pppoa_username=user@isp.com pppoa_password=abc123ABC pppoa_idle=0 pppoa_ipaddr=
