I've given up on Network Manager a while ago. Why? Because most of the time I use 3G modem to connect to Internet and Network Managers 3G support varies from release to release. Earlier I wrote about managing GSM mobile broadband connections without Network Manager on Red Hat Linux, CentOS, Fedora based Linux distributions and on Ubuntu, Linux Mint, Debian based Linux distributions. In this article I will explain easiest way to configure Internet Connection Sharing on Ubuntu Linux based operating system.Continue reading
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.Continue reading
Recent Network Manager versions like Network Manager 0.9.1 from Ubuntu 11.10 and Network Manager 0.9.2 from Fedora 16 and aren't working well with both of my GSM mobile broadband modems, Huawei E220 and ZTE MF100. Actually this aren't first Network Manager version that refuse to work with the same hardware, there were some problems back in the good old Ubuntu 9.10 days. Because of that I had to learn managing my mobile broadband network connections without Network Manager. In this article I will do my best to point you in the right direction to managing your GSM mobile broadband connections from terminal without Network Manager on Ubuntu, Linux Mint and Debian based operating systems.Continue reading
The other day I was writing a script that needed to do its job only when specific network interface is triggered (wireless broadband ppp0 in my case). Pinging Google every 10 seconds to detect Internet access was out of the question. There is a more elegant way to do this. If you are interested please proceed.
Do you know that authors of Network Manager built option to trigger scripts right into this great application. 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.Continue reading
