Incompatible versions of Mysql 4.0.x and NPTL based systems?

by Michael Zarozinski

*/Hi, I logged into WebHost Manger on our server today and was presented with this message: Important Notice: Incompatible versions of Mysql 4.0.x and NPTL based systems./* If you are running a newer linux system which is NPTL based (CentOS 4, Fedora 3+, RHE 4, etc) and are having problems with MySQL 4.0.x (versions later then 4.0.23*), we recommend upgrading to MySQL 4.1.x as we have determined that there are compatibility issues on these platforms. We're running RHE4 (which _is_ NPTL based) and MySQL 4.0.26 Can anyone point me to more information about this issue so I can determine if we need to upgrade. Thanx, Michael Z

Re: [Wlug] hald in ubuntu 'dapper'

Ok. It's now working as it should. What I did was 'sudo dpkg -P --force-depends hal' followed by 'sudo apt-get install hal' With the 'new' hal, all is working. I must've been the victim of an intermediate broken hal version during an intra-dapper upgrade.

Re: [Wlug] hald in ubuntu 'dapper'

by Chuck Noyes

Some more information about this problem; "adept" downloaded some upgrades this morning. Among them were some 'hal' files (hald, hal-device-manager, and a couple of others). After installing these updates, I rebooted my laptop and tried to pass the --retain-privileges argument to hald (e.g. sudo hald --daemon=yes --retain-privileges). The result was that the hald still barked at me for using the --retain-privileges argument. BUT, the hald man page reports that --retain-privileges IS a valid argument, however running 'hald --help' reports that --retain-privileges is NOT a valid argument. Obviously there's something going on here that needs to be fixed. If I go to http://freedesktop.org/wiki/Software_2fHalTraces, I should be able to use the --retain-privileges argument. My version of hald is 0.5.7. Anyway, it looks like a bug. Someone reported bug #44770 against hald in the ubuntu bug tracking system and it's new, only a few days old. It's very similar to what I've found. There's a comment in the bug report, from a developer or maintainer, that says the --retain-privileges was never valid for the ubuntu hal...oh well.... -Chuck Chuck Noyes wrote: > Hi All > > I upgraded by laptop from 'breezy' to 'dapper'.

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

Re: [Wlug] Water sensor project

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.

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. 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

Re: [Wlug] Water sensor project

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.
