In my last article I have described how to manage manage GSM mobile broadband connections without Network Manager on Debian based distributions like Ubuntu and Linux Mint.

In this article I will show you how to do the same on Red Hat Linux based Linux operating systems like CentOS and Fedora. I recommend that you read "Introduction" and "My hardware and ISP configuration" paragraphs from my last article to get acquainted with my exact hardware and Internet Service Provider configuration. Required procedure is a bit simpler for Red Hat Linux, CentOS and Fedora because there is some abstraction in accessing basic pppd options. Also Red Hat network configuration files are differently arranged (better than Debian in my opinion) and because of all that this article is a bit simpler to follow than it's Debian counterpart.
