A controlled dial-on-demand router is a convenient tool. An uncontrolled dial-on-demand router is not. The Wireshark network protocol analyzer helped me track down the cause of some strange and unwanted dialup connections.

My dirty walk-through to setting up an external modem in Linux using wvdial to dial into an ISP connection. I had some trouble finding a single place with a good write-up for doing such a task when I was setting up a Linux box for someone that had previously been using Windows and a little OS X. Finding dialing info, modem configuration, or slight troubleshooting, alone wasn't too difficult, but finding them in one place in a concise manner was. So I have attempted to compile what I have found, my tweaks and adjustments, and other hints that enabled me to setup a Linux box to use a dial up connection via external modem.

NoMachine NX is a Terminal Server and remote access solution based on a comprising set of enterprise class open source technologies. NX makes it possible to run any graphical application on any operating system across any network connection at incredible speed.

Ubuntu includes some useful utilities to get your dial-up connection up and running. Here are the ways you can connect to your dialup connection:

A cellular plan using an EVDO modem can provide a connection with bandwidth of approximately 3Mbps to the client and 1.5Mbps up to the provider (comparable to DSL) for a much lower cost than alternatives such as satellite.

I have recently bought a Huawei E220 HSDPA access device (or a so-called “3G modem”) from Three UK. In this article I’ll share with you my experiences of using it in Ubuntu Linux distribution. And don’t worry, it works just fine

With current virtualization technologies it is possible to pass through devices from the host to the guest, calld USB pass through. KVM is no exception here, it even works with a USB GSM modem.

I thought it would be handy if I could come up with a script to keep track of my current IP address for me. The first step is to find out my current IP address. In my case, I have a SpeedStream 5100 DSL modem. The address of the modem on the local network is 192.168.0.1 and entering that address into a web browser will bring up a page that looks like this.

Like many people who aren't able to get DSL, I use mobile broadband. Typically, at least in Ireland and the UK, you are forced to purchase a modem with your contract.
