Red Hat LogoIn 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.

To use this option you need to write bash script with some specific bash variables and put it to "/etc/NetworkManager/dispatcher.d/" directory. Specific variables are necessary to receive instructions from Network Manager about network interface that triggers execution of your script and should it be executed on "up" or "down" operation on that interface.
