Business idea

Feb. 3, 2011

I was considering reviving my PC business by selling computers with linux preinstalled. Does anyone have any distro suggestions aside from Ubuntu and mint? Do any of you know anyone who may be interested?

Kernel Crash dump
by Andy Stewart Feb. 3, 2011

Feb. 3, 2011

HI guys, I finally got some type of crash dump from my system. I have tried Ubuntu variations of the 2.6.35, 2.6.36, and 2.6.37 kernels, all of which have crashed on me. Finally, 2.6.37 gave me a trace on the console screen. I had to copy it down by hand, so don't take it too literally. Here is the data. I intentionally left out all of the hex addresses in the call trace. It seems pretty obvious to me that something is amiss in the hardware. I wonder if my heat syncs are full of dust. That will be the first thing I check. Any helpful advice would be most appreciated. Thanks!

Try leaving the mem test running for a while, see if it will do it with that running. Could have just been the dust too lol.

Well, I cleaned out a bunch of dust...maybe a heat problem caused some weirdness. I'm also running memtester on the live system...so far, so good. The machine is about 5 yrs old - maybe this is my excuse to build myself another one. The crash is weird, sometimes it crashes within a couple of minutes of booting the system, and other times, it takes a week. I still claim that it started happening when I upgraded from SuSE 10.1 to Kubuntu 10.10, but I did open the case and install a new SATA hard drive at that time as well. This machine was an absolute rock when running SuSE 10.1. We'll see what happens...thanks, everybody, for the helpful suggestions.

Unstable Linux in recent releases
by Andy Stewart Jan. 19, 2011

Jan. 19, 2011

HI gang, I've read an awful lot of posts recently describing freezing or hanging systems in very recent versions of several Linux distributions. Unfortunately, I got one of them - Kubuntu 10.10 (I *knew* I shouldn't have upgraded from the very stable SuSE 10.1, except that it was quite old). My system arbitrarily hangs/freezes at unpredictable intervals. Sometimes I can make it happen 2 minutes after a reboot, and other times it takes a few days, but invariably, it does occur. I can usually induce it by doing something semi-stressful to the video, like watching something via mplayer, but it doesn't always occur. The postings I've seen appear to describe a wide variety of hardware and software configurations, and nobody can seem to find any error data in any log file. What I can't find is the solution, and I've googled extensively. Has anybody found anything online that talks about some very recently discovered bug and its fix that would cure the problem? Thanks!

Unstable Linux in recent releases
by Kevin Paetzold Jan. 17, 2011

Jan. 17, 2011

In case no one made the connection between my previous messagesubject and this thread..... They are the same. I believe that the fix i pointed out is the cause of these "unstable" linux's. Certainly the fix worked for me. When I first booted with one of the fixed kernels it ran for a wk (before i rebooted). Previously my machine was hanging at least once per day and at some points every hour or so. And in answer to previous question, the machine was hung such that it was not possible to ssh into it or make it respond in any way. Indeed after using the power switch to turn off the machine I still had to pull the AC plug to get it to be able to reboot.

hanging kernels #2

Jan. 17, 2011

I meant to say that I am now running vmlinuz-2.6.35.10-77.fc14.i686 from fedora 14 koji. Both the above kernel and vmlinuz-2.6.35.10-75.bz667459.fc14.i686 seem to resolve the issue. http://kojipkgs.fedoraproject.org/packages/kernel/2.6.35.10/77.fc14/ In fedora this problem seemed to show up with the 10-72 kernel and was perhaps even worse with 10-74 kernel.

hanging linux
by kevin.paetzold Jan. 17, 2011

Jan. 17, 2011

I recently saw comments on this list about kernels that hang. Indeed that was/is true for fedora 14. The symptoms I saw were essentially a frozen screen with no mouse pointer etc... In my case I would actually have to power cycle (actually pulling the ac plug) my dell pc to reboot it. In my case I believe that the bug (in fedora land) was bz667459. see https://bugzilla.redhat.com/show_bug.cgi?id=667459 I was a comments in this bug pointed me at a bug fix kernel "vmlinuz-2.6.35.10-75.bz667459.fc14.i686". This kernel resolved the problem. By the way, I have now upgraded (on friday) to vmlinuz-2.6.35.10-75.bz667459.fc14.i686 from koji which has also been stable.

Andy, I'm sorry, I got the emails mixed up. It could be a driver issue, but I only suspect that due to the freezing under heavy video load. Could I also suggest trying a different video card to eliminate hardware issues? The video card may have started to fail as you switched distros, unlikely but possible?

Dec Meeting announcement / linux-raid problem
by Eric Martin Jan. 16, 2011

Jan. 16, 2011

I just realized that I haven't received anything from WLUG in over a month, including the announcement for this past meeting. Did anybody else have this problem or is it just me? Now, the main reason for my email. My mythbox / home file server runs linux soft-raid in RAID5 with 3 500GB disks. One disk went bad a while ago and the array never rebuilt itself. The other day, the second disk went bad. Am I hosed? I've been googling for 'rebuild bad linux software raid' but all I get is the rebuild command. Also, I don't see any tools that will move bad data to another spot on the disk. This is my first time using software raid so I'm in a bit over my head. thanks! -- Eric Martin

Old man and LINUX
by Ken Jones Jan. 14, 2011

Jan. 14, 2011

Folks, I have always wondered at my ability to keep the myriad of LINUX instructions in my head. What would I do if I were to start losing them? Is there a tool to search for recall? Is there any way to go backwards in LINUX command land? If I were to remember that there is a command that will print on standard output the contents of a file in txt characters, but could not for the life of me remember 'more'. Where would I go for help (other than sending a email to this list serve)? All the command dictionaries I have are alphabetic. Ken Jones (the elder)

Re: [Wlug] Old man and LINUX
by Steven Greenberg Jan. 13, 2011

Jan. 13, 2011

Unix/Linux command names were exactly what drove me crazy when I first had to use Unix. I wanted to list something on the terminal, or maybe type it. Who would have thought to "cat" it or "more" it. And then we have the aptly named utilities like "awk". I was so proud when it finally dawned on me what the letters "a" "w" and "k" stood for. So I eventually did learn all the commands, but I never thought about the problem of forgetting them until this digest entry. I had the same reaction to emacs in the beginning. Doing apropos in emacs is not helpful when the concept you associate with the task is nothing like the way it is named or described in Emacs. I have learned to write down in a diary on my computer every time I finally find the hard to find command in either Emacs or unix/linux. The next time I want to do the same thing and I have forgotten what the command is, and I finally give up trying to find it in emacs, I can search my diary. Chances are the diary entry will be associated with the word I mentally associate with the task. /Steve -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.

In this case, I just did 'man -k text' and the last things that popped up were 'zmore'. Plus a bunch of other system calls and library calls about text handling. Maybe pickup one of the linux for beginners books that O'Reilly puts out? Unix in a Nutshell, etc. That should help you find commands.

If you remember the command, but you can't recall what options you used with it, 'grep some-command .bash_history' can help. You can set the system to hold more commands, if you want. In debian, the default is to hold the last 500 commands. I don't recall what it is in other distros. Spiral-bound notebook is good, too. A couple of pages of your favorite commands and just about anything else will still be readable if the system crashes.

Proposed Meeting topic: Virtualization technologies...
by Tim Keller Jan. 10, 2011

Jan. 10, 2011

Hey Gang, I'd be up for giving a talk about virtualization technologies. Type 1 vs. type 2 hypervisors, open sores vs. closed, etc. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

disk/Raid ideas
by Doug Mildram Dec. 21, 2010

Dec. 21, 2010

You're hosed (i think) unless -- you're rich and you send the disks to a shop for megabucks (they may start with a trivial purchase of 2-3 identical model disks) -- OR IF your problem was NOT the actual platters/heads, YOU obtain 1-2 same-model disks, swap the board from a replacement disk onto your hosed disk ( w/ sm torx tool and brave fingers ) I've not done this myself yet. I HAVE had "stiction" problems where (after a power out or a "rest" so a disk bearing/lubricant gets a chance to harden) the disk just isnt spinning up. Of course, tapping/whacking it at the right/initial moment will usually cure that and you can feel if it's spinning or not....if you can hold it in your hand ...OR somehow get hands-on during powerup.

Announce: Next WLUG meeting & meetings for 2011
by Chuck Anderson Dec. 20, 2010

Dec. 20, 2010

Hi folks, Our next WLUG meeting is scheduled to be held on Wednesday, January 12 at 7:00 PM at the WPI campus in Worcester, MA USA. The meeting room is in WPI's Morgan Hall (building 'H' on the campus map [1]), down the hallway to the right of the dining hall entrance. [1] http://www.wpi.edu/Images/CMS/WPI/walkingmap.pdf Also, I have normalized the meeting schedule to be the 2nd Wednesday of each month. We'll try this for awhile and see how it goes. As always, please email me if you are interested in presenting a topic for any of our future meetings. We're a very laid back group, so don't feel you need to have a polished presentation in order to speak. Demos are always fun too. Some topic ideas we've had are: - Linux Android Development - Linux on Wireless Routers: OpenWRT, DD-WRT, etc. - IRC basics: how to chat on #wlug-ma - PGP/GPG keysigning party - Compare ZFS vs. BTRFS vs. ... - Virtualization Technologies KVM, Xen, VMWare - Demo the latest version of your favorite Linux distribution Happy Holidays and I look forward to seeing you next year, Chuck President, Worcester Linux Users' Group

Reminder: WLUG Meeting tonight! (11/10)
by Tim Keller Nov. 10, 2010

Nov. 10, 2010

Hey Gang, Tonight we've got a WLUG meeting in the conference room adjacent to the Morgan Hall dining room at ~7PM. Though we're usually there a bit earlier. As of yet, there's no designated speaker so it'll be a round table discussion, unless someone steps forward, the floors open. Following protocol there will be consumption of pizza afterward. Hope to see you there! Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".
