Wireless Video and Linux

by Ritacco, Alan

Has anyone had any experience with wireless video camera(s) along with motion sensor detection and recording in Linux? Looking for what works well, what to buy, install, etc. Thanks Al

So the little house-shaped light with the "A" inside it that represents the state of the Caps Lock function doesn't blink all by itself? Because if it does, that indicates that the kernel paniced. If it doesn't, then the kernel did not panic.

I can turn the light on (ThinkLight) and the NumLock. Other than that, no keyboard interaction happens. Thanks!

Walt, Next time it locks up, after you reboot, get a look at /var/log/messages. Page down to check the last entries before the reboot, which should tell you what was going on when it froze. Do: less /var/log/messages which will output the actual text of the messages that are being saved in the /var/log directory.messages. You might need to be root to do this --we do have to be root in Debian and in Ubuntu. Since you have: > messages > messages-20090125 > messages-20090201 > messages-20090208 > messages-20090215 it means there are several message logs that have been made recently. You could also output: less /var/log/messages-20090215 But let's see the last bunch of entries in the latest one. You could also select text from these messages, and google that for forum postings.

Re: [Wlug] Fedora freezes

by E Johnson

I had something like this too, in Debian (etch). In my case it was a string of USB disconnect/reconnects, related to either the mouse or the keyboard. /var/log/messages turned up hundereds of messages about this, eventually it would run out of new device numbers to assign to the "new" USB device (keyboard or mouse) and everything would lock up. Yes, when Firefox was running, but I think I reproduced it in Ubuntu 8.04 when no browser at all was running. Upgraded to Debian Lenny some weeks ago, and still had the USB disconnect/reconnect problem although I think I managed to avoid the total-lockup problem --possibly only because we rebooted several times due to power failures & etc. Now running PS2 keyboard here, resulting in no more USB disconnect/reconnect messages in /var/log/messages and no more lockups since then. Running mouse plugged into the laptop running Ubuntu (8.04 hardy) now results in the same USB disconnect/reconnect messages, although it has not locked up yet. But I haven't used it much lately, either. I did notice the other day that it was running a little hot --maybe because it never had a chance to suspend, because of this disconnect/reconnect thing that's constantly happening. What did /var/log/messages report? Liz J 2009/2/21 Chuck Anderson <cra(a)wpi.edu>: > On Fri, Feb 20, 2009 at 07:35:14AM -0500, Walt wrote: >> I have been experiencing freezes with Fedora 10.

Re: [Wlug] cheap, small computer

by Tim Keller

Another option might be an HP T5730, we've got a model that has an optional PCI slot (so you could put in a hauppauge in the PCI slot. You can put a gig of ram in them and SSD's are small enough you can hide one inside. The only downer I can think of is that the video card is marginal. If you can push data out of the hauppauge that might be your best choice. I put pictures of this up on my picasa site: http://picasaweb.google.com/turbofx/Micro_pcs# Enjoy... Tim.

Re: [Wlug] Fedora freezes

Hi Walt, Anything in /var/log? TC Yes, what should I look for? (see below) Check memory and power supply. If you're using a realtime kernel, that's a possible cause of lockup. And if you want to reboot more gracefully, use magic sysrq keys. http://en.wikipedia.org/wiki/Magic_sysrq Note that the instructions say to hold down alt-sysrq, but on my system, that brings up the window to take a screenshot. I have to hold down ctrl-alt-sysrq. Then press keys, one at a time, with a couple seconds between each: r - e - i - s - u - b (or other keys, if appropriate. See the chart in the wikipedia article.) Greg This just started recently; I've had the notebook for almost a year. It's had Fedora 9 and 10 on it. I'm not sure if I have a realtime kernel. Next time it locks, I'll try the ctrl-alt-sysrq. I've been experiencing the same thing. I've assumed it was due to vmware and/or the new scheduler. At one point I got frustrated, confirmed that the computer could still be connected to and just left it alone. After 10 mins or so it started responding again. Seems to happen most when doing something intensive in vmware (like compiling a big program) and opening tabs in firefox. Dennis Payne dulsi(a)identicalsoftware.com I seem to have VMware installed (if I type vm TAB TAB I get a bunch of choices, but if I rpm -q vmware, it's not installed), but I can't seem to get it to work, I use virtualbox. Thanks for all your help!

I ran into a problem like this in Ubuntu 9.04 beta for a bit, it took an upgrade to fix.
