I have a linux machine with an internal modem. The linux I’m using is Ubuntu and would like to know how to connect this machine to the internet. I am not on a network, just a single linux machine.
I appreciate your reply.
Thank you.

An internal modem requires a Linux driver. The FIRST step towards finding a Linux driver is identifying the modem’s CHIPSET. I recommend visiting following url and download the scanModem tool which will help you to identifying the modem’s CHIPSET.

More information is at http://linmodems.org/

Another option is use lspci command to identify the modem’s chipset. Once you know the chipset, you can download & install the driver. Next, just follow the instruction mentioned here to configure PPP dial out.

I am able to dial out to my ISP, but I always have to type in the root password. I am on Ubuntu.

Is there anyway to disable this?

You can disable it via sudo command itself. Add something as follows, first type sudo:
sudo visudo

Next Append text:
username localhost= NOPASSWD: wvdial

To use type command:
sudo wvdial

It will not prompt for your password.

Hope this helps!
