Using tshark to Watch and Inspect Network Traffic

Linux Journal - Mon, 08/31/2015 - 13:53

Most of you probably have heard of Wireshark, a very popular and capable network protocol analyzer. What you may not know is that there exists a console version of Wireshark called tshark. The two main advantages of tshark are that it can be used in scripts and on a remote computer through an SSH connection. more>>

Where's That Pesky Hidden Word?

Linux Journal - Fri, 08/28/2015 - 13:17

I've been promising my 11-year-old for a long time now that I'd write a program that would let you build custom word searches based on a list of words given by the user. I wrote one years and years ago in C, but since I can't find that code any more and wanted to tackle another interesting project for this column, that's what I'm going to look at herein. more>>

A Project to Guarantee Better Security for Open-Source Projects

Linux Journal - Thu, 08/27/2015 - 13:13

With many open-source projects built on top of others, a security weakness in a common piece of infrastructure can have far-reaching consequences. As OpenSSL's Heartbleed security hole demonstrated, these vulnerabilities can appear in even the most trusted packages. more>>

Concerning Containers' Connections: on Docker Networking

Linux Journal - Wed, 08/26/2015 - 13:58

Containers can be considered the third wave in service provision after physical boxes (the first wave) and virtual machines (the second wave). Instead of working with complete servers (hardware or virtual), you have virtual operating systems, which are far more lightweight. more>>

My Network Go-Bag

Linux Journal - Mon, 08/24/2015 - 12:55

I often get teased for taking so much tech hardware with me on trips—right up until the Wi-Fi at the hotel, conference center or rented house fails. I'm currently on vacation with my family and some of our friends from Florida, and our rental home has a faulty Wi-Fi router. Thankfully, I have a bag full of goodies for just this occasion. more>>

Doing Astronomy with Python

Linux Journal - Wed, 08/19/2015 - 12:52

One of the things that makes Python so powerful is that you can find a module for almost anything. In this article, I cover Astropy, which was originally developed by the Space Telescope Science Institute for doing astronomy calculations like image processing and observatory calculations. more>>

Linux Journal - Mon, 08/17/2015 - 09:49

Through the years, Firefox has enjoyed a reputation as one of the most secure Web browsers on any platform, and it's the default browser for many Linux distros. However, a security exploit appeared this week that has shown users they can't afford to be complacent about security. more>>

diff -u: What's New in Kernel Development

Linux Journal - Thu, 08/13/2015 - 13:53

Linus Torvalds reported on some GCC compiler warnings that he felt were unnecessary, and he gave his opinion on how they should work instead. Specifically, GCC 5.1 would issue a warning against using a switch statement with a boolean variable, presumably because a boolean would be better handled by a simple if statement. more>>

Bounce Around IRC with ZNC

Linux Journal - Wed, 08/12/2015 - 14:43

In my discussion on IRC with "bkidwell" (see the Non-Linux FOSS article for more on our talk), we were discussing how we connect to IRC. My main method is to SSH in to my co-located Raspberry Pi in Austria and connect to a screen session I have running that is constantly connected to IRC with Irssi. This works really well for me, and I never miss messages when I'm away. more>>

Problems with Ubuntu's Software Center and How Canonical Plans to Fix Them

Linux Journal - Mon, 08/10/2015 - 12:01

Ubuntu has received a lot of flack from the community for some of its commercial projects. Placing Amazon ads in Unity's Dash is a classic example of a poorly planned move that flies in the teeth of the community's ethos. A community built on the concepts of freedom and software that empowers the user (instead of some commercial concern) would never take that well. more>>

Non-Linux FOSS: Flaky Connection? Mosh it!

Linux Journal - Thu, 08/06/2015 - 13:52

Most of the work I do on computers is done via the command line. When I'm off on vacation somewhere, that means shoddy Wi-Fi and cell-phone tethering. Because cell-phone tethering gets expensive quick (I also have three teenage daughters with which I share a data plan), I try to use free Internet whenever I can. The biggest hassle with that method is dealing with broken SSH sessions. more>>

Three More Lessons

Linux Journal - Tue, 08/04/2015 - 12:36

[In June 2015, I gave a commencement address to the graduating class of High Mowing School in New Hampshire. I wrote many drafts for the talk, all toward extemporizing the final thing. My experience with Linux and open-source hackers had an influence on it and gets credit as well. That's why I'm sharing it here.—Doc] more>>
