IPTraf, a ncurses based LAN monitor

Filed under
Software

Sometimes you just want to see what connections your machine is making to the outside world and what ports it’s using. While wireshark and tcpdump are really nice for inspecting detailed package contents. IPTraf is really about connections and interface statistics. Because iptraf is based on ncurses the program can be run from a text-console and still have a (primitive) `gui`. Navigation through the menus can be done using your arrow keys. Most of the time all the available options and their keys are shown on the bottomline of the sreen.

Starting up

By default the program is not accessible by ‘normal’ users so you’ll need root access. Also iptraf can put your interfaces in promiscuous mode (this will probably show up in your logfiles as: ‘device eth0 entered promiscuous mode’). Promiscuous mode can be turned off and on in the configuration menu.

  • The End of Gmane?
    In 2002, I grew annoyed with not finding the obscure technical information I was looking for, so I started Gmane, the mailing list archive. All technical discussion took place on mailing lists those days, and archiving those were, at best, spotty and with horrible web interfaces. The past few weeks, the Gmane machines (and more importantly, the company I work for, who are graciously hosting the servers) have been the target of a number of distributed denial of service attacks. Our upstream have been good about helping us filter out the DDoS traffic, but it’s meant serious downtime where we’ve been completely off the Internet.
  • Pwnie Express makes IoT, Android security arsenal open source
    Pwnie Express has given the keys to software used to secure the Internet of Things (IoT) and Android software to the open-source community. The Internet of Things (IoT), the emergence of devices ranging from lighting to fridges and embedded systems which are connected to the web, has paved an avenue for cyberattackers to exploit.
  • The Software Supply Chain Is Bedeviled by Bad Open-Source Code [Ed: again, trace this back to FUD firms like Sonatype in this case]
    Open-source components play a key role in the software supply chain. By reducing the amount of code that development organizations need to write, open source enables companies to deliver software more efficiently — but not without significant risks, including defective and outdated components and security vulnerabilities.

    In a blog post, Jeff Vander Stoep of the mobile operating system's security team said that in the next build of the OS, named Nougat, Google is going to be addressing two key areas of the Linux kernel that reside at the heart of most of the world's smartphones: memory protection and reducing areas available for attack by hackers.

Chew on this: Ubuntu Core Linux comes to the uCRobotics Bubblegum-96 board

Linux and other open source software have been in the news quite a bit lately. As more and more people are seeing, closed source is not the only way to make money. A company like Red Hat, for instance, is able to be profitable while focusing its business on open source. Ubuntu is one of the most popular Linux-based operating systems, and it is not hard to see why. Not only is it easy to use and adaptable to much hardware (such as SoC boards), but there is a ton of free support online from the Ubuntu user community too. Today, Canonical announces a special Ubuntu Core image for the uCRobotics Bubblegum-96 board. Read more
