    • Why it matters if someone exploits your web server:
      • Server / web site performance

    • Step One: Determine if your web server is exploitable. Using lynis to check the security of your Linux server or computer, and generate suggestions for what you could do to help improve your security on the server level.
      • Installation:
        sudo apt-get install lynis
      • Execution:
        sudo lynis -c -Q
    • Step Two: Determine if your web site code is exploitable. Using StopTheHacker to test your web site and server from the outside world.
      • Launch the web site:
      • Running a Web Site Vulnerability Check using StopTheHacker.
      • Using apachetop as per our feature on Episode 295 to monitor the activity of StopTheHacker.
      • Once the StopTheHacker scan is complete (well, approximately 24 hours later), you will receive a full report by email which tells you what parts of your web site and server have been found to be exploitable.
      • The paid plans at StopTheHacker will give you proactive detection and protection for your web site.
    • Step Three: Now it's up to you to fix it. Now that you know what kinds of exploits are possible on your server and web site, it's up to you (or your web designer, for a fee) to patch your web site, and do this at least every 6 months.

  • {play 38:33}Viewer Questions
  • Happy belated birthday to Robert Gorczynski's mom.
  • Viewer Comment: Congratulations to Abigial for her marriage!
  • Viewer Question: I just watched your video about setting up Wirecast and see you could adjust the contrast and settings for the camera. Is this a feature of Wirecast, or the camera?
  • Viewer Question: System 76 is not available here, and I'd like to switch to Linux, but I understand Linux can be more picky about what hardware you use. So how do I know what type of system to build for Linux?
  • Viewer Question: On Robbie's personal web site, Robbie is called DJRobbieF. Does DJ stand for disc jockey, or data jockey?
  • Big news for RSS subscribers all around the world: we are in the process of migrating all our RSS feeds to a new CDN which will be accessible from all countries, and it will also result in faster file delivery for all users. See Robbie's Blog for more details.
  • Viewer Question: I cannot get Team Viewer working on Point Linux. Can you show us how to install it?
    • Installing Team Viewer on a multiarch system such as Point Linux or Debian 7 requires you to install their 32-bit version, because Team Viewer's 64-bit version is only compatible with the old ia32-libs way of doing things (at least, at the time of this broadcast).
    • Installing the 32-bit version of Team Viewer on a multiarch system, assuming you have the 32-bit teamviewer_linux.deb file in the current folder:
      sudo dpkg --add-architecture i386
      sudo apt-get update
      sudo dpkg -i teamviewer_linux.deb
      sudo apt-get install libxtst6:i386
      sudo apt-get install -f
  • Viewer Question: I have not been able to get my nVidia graphics drivers installed on Point Linux. Can you show me how to do it?
  • {play 57:23}Contest Announcement: Win a 7-port Newer Technology USB 2.0 hub with dedicated 2.1A power port on Episode 301.
