Re: [Wlug] hald in ubuntu 'dapper'

by Jared Greenwald

I'm no hald export, but I think you're mixing commands. Seems like you want to restart the hald init service, but you're actually just calling the daemon straight-up. I think you want: sudo /etc/init.d/hald restart Sine the --retain-privileges option is set in /etc/default/hal file you shouldn't need it on the command-line (the init script won't accept it anyway). If it still fails, add "--verbose=yes" to /etc/default/hal file to get some debug messages. Let us know what happens... -Jared On 5/22/06, Chuck Noyes <vze284qe(a)verizon.net> wrote: > Hi All > > I upgraded by laptop from 'breezy' to 'dapper'.

hald in ubuntu 'dapper'

by Chuck Noyes

Hi All I upgraded by laptop from 'breezy' to 'dapper'. It looks like the hald does not accept the --retain-privileges argument, even though the upgrade tool added it to the /etc/default/hal file. Now the hald won't start. Also, my USB thumb drives won't automount. I'm thinking it may be related to the hald problem. If I run 'sudo hald --retain-privileges restart', the command fails with the help screen for the command. Has anyone else out there seen this problem? Anyone got a fix? I can always comment out the 'DAEMON-OPT=--retain-privileges' line in the /etc/default/hal file, so the hald starts without error, but the USB drives still don't automount. Thanks, -Chuck

Well, i'm getting closer: http://www.ideativeinc.com/leakfrog.cfm http://www.amazon.com/gp/product/B00004W4B4/102-3009714-8566516?v=glance&n=… I'm thinking I can use this, but then splice into the wires and something something something... I think finding the sensor might be easy....can anyone point me to the means to communicate with it via linux? I'm guessing something as simple as "if circuit is open, do nothing, else page mike", but I am at a complete loss on how to go about that piece of it. Andy's idea of listening for the alarm is good, but what happens when I crank my Battle for Middle Earth II game to max? thanks again and I am still looking through those other sites...thanks john. --- John Stoffel <john(a)stoffel.org> wrote: > > Mike> So i was thinking today, why not put an H2O sensor in and have > Mike> one of the dozen or so computers page/email me when there is > Mike> water present? > > Take a look at the Dallas Semiconductor one-wire sensors.

Take a look at the Dallas Semiconductor one-wire sensors. I've got one sitting right next to me here at work. It's basically a DB9 serial port dongle (DS9097U-9) which connects over standard ethernet cables to various sensors. The sensors all have unique IDs and can be addressed by linux software. Take a look for the Digitemp software. It has the drivers for watching various sensors like this. I built a bunch of temp sensors for a server room so I could watch temps on the cheap: http://www.digitemp.com/products.shtml He's not selling hardware anymore, but it's good links to sensors and such. Here's another link page: http://www.ibuttonlink.com/Sensors.htm which looks really neat. Good luck with the water! John

If you have a free serial port open, you could wire up an open/close switch to one of the handshaking lines to easily detect a water level over a certain point. The open close switch could be some kind of floater like the way sump pumps activate.

Re: [Wlug] Water sensor project

no doubt i have some sump pump work ahead of me as well. it wasn't actually the pump that failed, but the hole, but that is another story. NOT having water in the basement is MUCH MUCH better than having water but getting paged because of it...but even with 2 sump pumps, a mule and sand bags, I would rather know when they all failed and be notified, than not. This seems like a $4 dollar solution...plus an excellent opportunity to learn something new...besides how to make a hole in concrete 6 inches wider! --- Marc Hughes <marc.hughes(a)gmail.com> wrote: > I hate being the practical one, but take the time & money you'd spend > on that project and install a backup sump pump.

I've never seen a "sump pump cam" before - maybe you'll be the first?! ;-) Perhaps you should get a water alarm with the ear piercing alarm, and attach a microphone to the computer.

I hate being the practical one, but take the time & money you'd spend on that project and install a backup sump pump.

Water sensor project

by Mike Leo

NOTE: Cut and pasted from a web post of mine...i just didn't want to re-write it... Since my arc isn't built yet, and we have recieved 27 feet of rain here in New England in the past 7 days, my basement flooded again. The pump went out sometime overnight and i had 3-4 inches of water in my basement/computer room this morning. I am smart enough, however, to have everything up off the floor (except my sun workstation!), so nothing was damaged but the carpet. So i was thinking today, why not put an H2O sensor in and have one of the dozen or so computers page/email me when there is water present? But......I am not a programmer, nor do I have any idea how to interface software with a hardware sensor (that I can't actually find at present on the web). So the quetion is, where do I begin? A quick google search finds alarm sensors, but no interface to a computer serial port...they just start screaming if they get wet. Even if i did find one, where do I start with such a thing, to interface with an OS to trigger an action? Does someone know of a (cheap) product to do this? Not only does is seem like a practical project for the house, I'm sure it will be a good learning experiance as well. Thanks for any advise...I'll be out collecting animals
