odbc help

by Mike Leo

Has anyone ever gotten a linux box to speak to a MS SQL server? I am only assuming i need to configure an odbc DSN from linux to MSSQL, but am not successful yet. The end goal is to get phpBB2 to talk to my existing MSSQL database. In order for that to happen, apache has to use php and php has to use an odbc connection to MS SQL. Well, php in apache is working now, and php is set to use MS SQL. isql -s SERVER NAME PWD connects me to my MS SQL database just fine, but iodbctest is failing. I don't know enough to know what is wrong. Any help would be greatly apreciated! mike

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

Take a look at the Dallas Semiconductor one-wire sensors. I've got one sitting right next to me here at work.

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.

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.

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. Write some software that detects the loud noise and informs you accordingly.

I hate being the practical one, but take the time & money you'd spend on that project and install a backup sump pump. You'll be far happier with a dry basement than knowing you have a wet one. -Marc On 5/15/06, Mike Leo <mleo963(a)yahoo.com> wrote: > 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 > _______________________________________________ > Wlug mailing list > Wlug(a)mail.wlug.org > http://mail.wlug.org/mailman/listinfo/wlug >

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

It might be worth a look there.

Network not working on Fedora

by Walt Sawyer

Friday night, my wife was using her computer (lenovo/IBM desktop), then the DSL connection went down (I wasn't here) and then her network card didn't work. That's about the time I got home and found that the on motherboard gig/100/10 Broadcom NetXtreme gigabit... stopped being recognized. OK, sometimes these motherboard NICs go bad. When booting in the redmond product, the ethernet connection was there. It was time to upgrade to Fedora Core 5 so I figured this was a good time. Perhaps the newer kernel would just fix the problem for me. Well, it didn't. It would detect that the correct card wasn't there. I checked dmesg and found no entrys for eth0. I tried adding a 3com (one of the most common drivers!) card and on bootup it didn't see it, but in the network configuration area I was able to add it as eth1 (the Broadcom was eth0). Upon rebooting, it looked for eth0 and eth1 and found neither responding. Is there any reason a NIC would just stop responding? This machine was working just fine until this issue. Thanks in advance Walt
