Boisel Linux Group Meeting Report - March 7th, 2013

Meeting started off well with 12 in attendance. Ed had brought a small system that he was trying to load from a bootable USB drive loaded with ClearOS, a gate server version, derived from Red Hat Enterprise Linux source code. We spent a little over an hour on this project. All would go well until just after partitioning, the installer would "lose" the install image that was on the USB drive or at least couldn't find it in order to continue. Ed's system is using Jetway IPC board, NF9D-2700, a miniITX form factor with an Atom processor, which was thought to be 64 bit. We tried some other USB bootable distributions which would complain about the processor not being compatible but found that Kubuntu 11.04 would install. Clint suggested that Ed use a bootable USB CD Drive to perform the install of ClearOS. After a successful Kubuntu install, Clint did a couple of command line checks and determined that it was running a "generic" kernel and that the processor would only support 32 bit operating systems, no PAE (Parallel Address Extension), but it was a multi-core, hyper-threaded system which showed the equivalent of 4 processors on a dual core processor. The board had a ton of features including HDMI, 2 Serial ports, 4 Sata 3.0 ports, and 2 gigbit network interfaces. Ed had bought his on eBay for $60, quite a deal for a bare bones motehrboard that retails at about $150-$200. When asked what Ed was going to use the system for, he talked about having an external facing webserver and internal facing file sharing along with a firewall, intrusion detection, and filtering all in the same box using ClearOS. The system would run 24X7 and needed to run cool, low power. This conversation took us to his webserver and a tour of his Boise Robotics file download area on a webserver that he has had up for 5 years running. Clint had promised to discuss VirtualBox at tonight's meeting and turned to that topic as there was still some interest. He discussed the two downloads for installing from Oracle, the main packaged and the extension pack. He showed the /etc/group file where you need to make sure that you add you user name (userid) to the vboxusers group. One of the questions asked was if a "bootable USB" device could be used inside a Virtualbox guest and we tried a couple that Hugh had brought but no magic was found, not like booting a LiveCD. We did some quick research on the Internet which took us to a "answer" Use Bootable USB Drives in a VM https://forums.virtualbox.org/viewtopic.php?f=7&t=52767. Conversations turned to keyboards and how difficult it is to find a quality keyboard. Favorites included the Northgate, Keytronics, and the IBM Keyboard that was so pervasive in the 1980's and 1990's. Darin mentioned that Canonical had announced that the Mir display server would be used in future versions of Ubuntu to replace the X windows server system, abandoning Wayland. http;//www.theregister.co.uk/2013/03/05/canonical_mir_aanouncement/ Ed was having an issue with installing Audacity on Windows 8 and was trying to check the sha-1 hashes as apparently he was getting a bad download, so a bit of time was spent on that which included Clint booting in Windows 8 and testing Audacity there, which worked. Conclusion was that the Audacity download site was having a "bad mix" that day. We also looked at a website where you can get a file verification tool that supports sha1 hashes in Windows. http://www.exactfile.com. It is currently in beta and free to download. Our next meeting will be April 4th, 6:30 PM, at the Boise Public Library.
