This LUG meeting met at Barnes and Nobles. We had about 10 people show up for the meeting.
At the meeting topics ranged from Hacking a laundry machine to getting training. As for training, Brad mentioned he took a $50 course through Piston. He said the training was ok, but the software tools they provided were more valuable than the course. Brad has been messing with Open Stack and GNU Parallels. Parallels he mentioned lets him backup his SQL tables all simultaneously. In compared to a linear backup script, Parallels spawns forks that process data fasters than a single process. On the learning side, Unallocated Space was mentioned. Unallocated space is providing study groups for people wanting to get pertifications. More information can be found here.

We met at Barnes and nobles. We had about 10 people show up for this meeting.
There were two talks going on at the same time at this meeting. On one corner of the table Tim Cash brought some hardware that was being troubleshot. We also had a talk about software. On software there was a question of how to make the Ubuntu updater ‘synaptic’ update without the need for a password everytime. The first suggestion was to use ‘sudo’ from a terminal window. Using sudo would allow a user to launch synaptic as root and prevent the need of a password. However, the user wanted to use the gui. This made the problem more complicated since the gui uses a different authentication mechanism. The gui uses policykit-authnetication for synaptic. However, policykit may have exceptions. Leroy had a question in regards to turning off geo location searches from Goggle. He said he wanted to put his searches through a different region. We showed him how to do this. However, another LUG user recommended he just use ‘private internet access‘ as alternative. Apperently, this group provides vpn access from multiple regions. Additonally on the software theme, there was more talk about virtualization. Many believe ‘docker’ will be the next big thing in application virtualization, but it still may not replace vmware completely.’Vagrant‘ another virtualization provider was discussed.

The January 2015 meeting was in Barnes and Nobles from 7PM to 9PM.
We had about 8 users. Tim C. brought in a broken ATX mini case that was missing a cover. He said that he was having a power issue. Brad the previous owner of this object advised him to screw the cover back on. The power supply accordingly did not appear to be properly grounded. The cover may be part of the ground for the case.
Brad B. talked a little about new and exciting FreeNas alternatives. FreeNAS has been the dominate player in providing a ‘Free SAN’. However, this is a FreeBSD solutions, and some want a Linux based solution. Although there is Openfiler, it has not been upgraded in a few years. Despite this Brad was excited to announce that Easy NAS and RockStor are two NEW Linux alteratives to FreeNAS. Brad B. is testing that both and seems to think that RockStor looks the most promising.
Dave B. mentioned he was worried about moving to a newer version of SUSE because his system is using software RAID. We recommneded he just make a backup of his data on a USB attached storage and then rebuild the machine and import the data. This should allow him to rebuild it without any data loss – in theory.
David C. mentioned he wanted to learn how to ‘backup’ his DVD collection on another type of media. This problem is still not solved. But, some software possiblities were mentioned.
Nobody has taken the LPI certification, but the LUG gets a discount with the ‘Meetup15′ code.
P.S. My new year resolution is to get all the meeting notes online in a timely manner. Please feel free to remind me. -Ted

We have been having great turn outs despite the cold.
On January 6, 2014 we meet. We had about 10 people.
The discussion started with Brad talking about Xen and Citrix. Apparently, Xen-Server is now opensource. This used to be a commerical product sold by Citrix while the simplier version Xen was opensource. The Opensource Xen-Server has many of the same features you find in Vshpere or Microsoft’s virutalization product. Most of the commerical product sell features like ‘live migration’ and ‘HA’, which Xen-Server does for free.
We talked about sandboxing a machine with ‘chroot’ and ‘lps’. This is one way to keep your Linux machine pretty safe while browsing the web. Other sandboxing solutions are lxc linux containers and docker installs. After talking about sandboxing a system, we went on to Glusterfilesystem and open media solutions in Linux. Some media solutions that came up were ‘media tomb’, ‘plex3′, ‘open media vault’.
On Dec 3, 2013, we had a similiarly large turn out. This meeting was all over the place. We started talking about desktop managers, and ended with security software. Someone mentioned that ‘flux box’ or ‘black box’ was better for running Wine applications on Linux. Another person mentioned that the new version of Mint16 broke Gnome compatiblity. Then we talked about the package managers. ‘Synaptic package manager’ was discussed shortly as one of Ubuntu’s main gui tools. For getting special packages, someone mentioned using ‘ppa’, which stands for ‘personal package manager’. Adding ‘ppa’s to your Ubuntu distro lets you gets software that you normally don’t have access to with the standard packages. Someone had a problem with lvm on a mixed drive that does both solidstate and regular SATA in the same device. We recommended a firmware upgrade. Virtual machines applications were discussed a little. Docke, kvm, vmware, xen, openbox, and parrells are some of the choices people could make. At the end of the meeting, ‘backtrack’ and ‘helix’ were talked about as forensic tools.
