[xawtv and webcam looping]

In the last year we've had the auto vandalized twice and have been relieved of three bicycles. I've put motion lights and sound triggers and a new dog all around this little flat. Recently we've discovered irrefutable proof that the perpetrators may actually be from next door. I am building custom MountainBikes and need to know my items are safe in the home. My solution (since we're already being cased) was to do a little casing of my own. And without getting into a drawn out justification, this is what we've done. Since the suspects are young, male, jobless, social misfits, they have all freaking day to study our routines. They know when the kids are in school and we are at work. I have set up a Logitech QuickCam Pro 4000. The darn thing worked right out of the box. Using 'webcam', a part of xawtv I am able to grab images and ftp them to the webserver. I also archive the images locally and with mencoder, condense them into AVI's. The beauty of this setup is I can monitor our vulnerable backyard entry from any browser in near real-time (currently a 15 second grab). Unfortunately, the xawtv program 'webcam' does not do what it is supposed to do and my work-around is generating big logs and consuming too much cpu on the workstation. 1) webcam doesn't loop at all like it's supposed to. 2) SSH transfer option could not be performed without manually entering a password. I even set up all the authorized keys and it still prompts me for a passphrase - I suspect an 'expect' syntax error, but I at least feel more secure... 3) ProFtp works but again, webcam refuses to keep-alive the connection. My solution was to create a script and run it from CRON. Now in addition to the ftp logons and transfers in /var/log/messages, I'm getting gobs of mail from CRON. Has anyone had success with xawtv and the webcam looping utility? farmer6re9 -- Eating Crow is better with MyCrowSauce -- The Toronto Linux Users Group.

That is the part that didn't work. When it came to the summary all I got was a blank screen and it stayed that way for hours until I rebooted with the reset button.

On the Mandrake lists (I would recommend joining) I've already seen at least 3 or 4 people who's system was hosed by an update, it is something to do with bad XFree86 update packages. Lemme guess, you couldn't get the graphical enviro up after the update, right? > The same thing happed this time as soon as it came to the summary part > of the install the thing just stopped.

Waitaminnit, the summary is where it's supposed to stop, unless I'm thinking of a completely different part. That's where you are supposed to configure X and/or any other hardware that hasn't been automatically configured by the installer, no? You have a list, and beside each item is a button which says "configured" or "not configured", etc. ? Beyond that, the only thing I can think of is, as I said before, you got a bad ISO in there. If you hadn't already just done a reinstall, I would recommend downloading the ISO's again, checking their md5sums, and burning fresh ones, but....sheesh, you've been through a lot already.

I thought you were actually going somewhere with that ! I read an intriguing book by *Richard** Mackarness that connected allergy and addiction. Perhaps amusingly, in your example the chap who drank the 100 proof, would only be fueling an alcoholic cycle, and the microdose recipe you suggested might even prove the key to breaking that cycle ! The book (a little of what you fancy) makes an interesting case. Much better that my current ramblings. *http://www.amazon.com/exec/obidos/search-handle-url/index=books&field-author=Mackarness%2C%20Richard/102-8797807-1288938 so laugh all you want, but microdoses have their applications, you whiskey drinking wicked, wicked man ! and anyway; SHOW ME THE PENGUIN ! have you forgotten that linux and all of the sisters sacred open source are the ONLY IMPORTANT THINGS ! a tangent from wayyyyyyyy off off topic, pass the whiskey sheesh ! djp -- The Toronto Linux Users Group.

Thanks for your reply Joe When I booted the computer the memory test was 327680 KB OK This is the information from the dmesg file that refers to memory it doesn't seem to have any problems there. Linux version 2.4.21-0.13mdk (flepied-JAOzawC1ADxn+L6o72McsUEOCMrvLtNR at public.gmane.org) (gcc version 3.2.2 (Mandrake Linux 9.1 3.2.2-3mdk)) #1 Fri Mar 14 15:08:06 EST 2003 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 00000000000a0000 (usable) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 0000000013ff0000 (usable) BIOS-e820: 0000000013ff0000 - 0000000013ff3000 (ACPI NVS) BIOS-e820: 0000000013ff3000 - 0000000014000000 (ACPI data) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) 319MB LOWMEM available.

I skimmed through the rest of the file and it was only information about devices on the system. There were no error messages any where. I'm stumped I like Mandrake though and I will find out what is wrong. I tried the on line update yesterday and I had to re-install the system again. I guess I need to learn more before I start with the on line updates. The same thing happed this time as soon as it came to the summary part of the install the thing just stopped. I waited for two hours and it didn't start again. I had to reboot with the reset button and fix the file system. It does seem to be working better this time though. But there is still a big delay in the applications starting. Some times I wonder if they are going to start and click again and have two instances. I know this is new and there isn't much support for it and I like the idea that Microsoft didn't have a hand in it.
