Feb 2015 meeting notes

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.

meeting notes for Dec 2013 and Jan 2014

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.

Nov 2013 meeting notes

We have been having very good turnouts for the meetings. All the chairs in the conference room are full. Today, we talked about various topics. Tim Cash started the talk with some questions in regards to building a new machine. He had some questions about monitors and DVI on a 24 inch. Dave D. mentioned that DVI has a max of 1900×1200 on 24 inch monitors. He also recommended ATI(AMD) Infinity cards. There was talk about filesystems, using duck duck go as a search engine, and rainbow tables for password encryption.

Jan 2011 Meeting Notes

We had a small group of 6-8 people this evening.

Items of Interest:
Brad was getting 25Mb Business Class Fiber from Verizon.
He said it took 30 calls to setup the order.

Talked about how Linux and Ubuntu are doing things differently. There seems to be a desire to make Linux more friendly to the masses. As a result, controls under the hood seem to be getting covered up by developers. Although this is helping new Linux users, hiding the controls is frustrating older Linux users. At the 27th Chaos Communication Congress in Europe, a sysadmin, Wolfgang Draxinger attempted to complain about missing documentation and his frustration with the current state of where Linux is going. We think that his goal was to show how Linux is becoming evil with it’s heavy dependence on multimedia. More specifically, Pulse audio, gdm, gs-streamer, and phonon are not very well documented. However, the developer of these applications had strategically placed himself in the audience and made is presentation a little award. Although there was a dialog between developer and users, the air of superiority from this one developer is exemplified in this youtube video. http://www.youtube.com/watch?v=ZTdUmlGxVo0

In the meeting, there was further talk of how to make Ubuntu like and feel like the old versions of Linux. More specifically, to get the virtual terminals now you need Console-kit. Console-kit is an application that keeps track who is logged in. Virtual-Terminal switching is being turned off in many newer distos. It needs to be explicitly turned on to use it now.

Brad talked more about puppet. Puppet allows you to run the same command on multiple machines. For example, if you need a jpg on a specific machine in a server farm, you run the puppet master command on your designated controller and the command gets executed on all the machines in the group. Puppet is saving Brad and his company a lot development time.

Dave D. mentioned that he purchased some Indy Games from humble indie bundle. The humble bundle generated $1M for charity.
Linux Games
Indy game ( humble bundle.com)
Amnesia the dark decent.
Dragon Age.
Infocom Games.
Oregon Trail

Brad has been using Suse Studio. To develop turnkey openvpn applications his customers can download.

We also discussed on-line gaming. Recently a person purchased a virtual space station for $600K. The previous owner purchased the virtual space station for $200K.
Pictures of the virtual space station can be found here.

There was also a question about how to wipe disks and Brad posted a solution for this on the list serve.
