A couple of weeks ago i installed my laptop with the new release of Fedora Linux: Fedora 12 with code name Constantine. As usual, i had to make it connected to internet. I used my AT&T USB Connect 881 modem with WvDial to connect. WvDial is a small linux utility that helps in making modem based connection to internet. It dials the modem and starts pppd in order to connect to internet.

WvDial consists of two main components which must be run as root:

  • wvdial, the pppd dialer that dials the modem
  • wvdialconf, is used to build configuration file for wvdial

How to connect:

  • Run wvdialconf to generate a configuration file, /etc/wvdial.conf, that contains information about modem and ISP.
    • wvdialconf messages

    wvdialconf messages

    wvdialconf probes for modem information and found it on /dev/ttyUSB0

  • The generated /etc/wvdial.conf should look something like this
    • Generated /etc/wvdial.conf

    Generated /etc/wvdial.conf

  • Remove the ‘;’ character from the Phone, Username, and Password line and replace the <Target Phone Number>, <Your Login Name>, and <Your Password> with the dial number, username and password from your ISP.
  • The final configuration should look something like this (one line are added to suit with my ISP settings)
    • /etc/wvdial.conf

    /etc/wvdial.conf

  • Run wvdial to connect to internet
    • wvdial connected

    wvdial connected

  • To disconnect, use Ctrl+C to terminate the wvdial.

Notes:

By default, wvdial will copy DNS address from ISP to /etc/resolv.conf, but in Fedora 12 you have to copy it manually (seems to be a bug).
