16 Apr '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, We have a WLUG meeting coming up on Wednesday, April 16th, at 7:00 PM. Directions to the meeting can be found on the WLUG website. There is a remote possibility that I will miss the meeting, which is why the meeting topic is listed as TBD on the website. If I cannot make it, I would recommend conducting the meeting as a Birds of a Feather session. However, if I am able to make it (95% probability), I'll bring my laptop, battery, DC-DC converter. We can have a discussion about reducing power consumption in laptops. I can do a quick demo of the PowerTOP application (see: http://www.lesswatts.org) I don't think this will take up the entire meeting, but we can use it as a starting point for further discussions. I also have the CPU frequency control applications installed to control the clock frequency. Naturally, we'll go out for food and refreshments afterwards. See ya later!

SPF
by Jamie Guinan 10 Apr '08

10 Apr '08

Hi, Are any of you admins out there running SPF, or something similar? http://www.openspf.org/ How well does it work for you? Today I started getting a large number of "undeliverable" responses due to spammers forging my email address in the From: address. Wondering if SPF is worth the trouble to set up. I'm using postfix, btw. Thanks, -Jamie

Linux System Admin recommendations?
by Andrew Schiller 06 Apr '08

06 Apr '08

We are a small local company that is trying to do something different. We have chosen open source technologies in building our ideas. As the company has become more successful we need help supporting them. We are looking for a team of folks who are passionate about technology and know open source to provide thoughtful, reliable system administration services for our Redhat linux os systems. We have made some bad choices in the past, and as a result received service that has hurt us. We don't know where to look for guidance in choosing, and we are hoping the user group can recommend some good folks who will be there when we need them with depth of knowledge and abilities in performing routine maintenance as well as emergency support when we need it. Your recommendations would truly mean a lot to us. Mercader

Missing /dev files
by Chuck Noyes 01 Apr '08

01 Apr '08

Hello, I had mounted an external usb drive /dev/sdb2 onto /media/sdb2 and was coping several mega-bytes of files to it when I got some I/O errors. Then I noticed that all of my /dev/sdb* files were missing from /dev. When I do an ls -al /dev, all the files are there except the sdb files. How can I get these back? I'm running Ubuntu 'gutsy' 2.6.20-16-generic. Thanks, -- -Chuck

Is the external USB drive self-powered? Did you power-cycle it at any point? The device itself might have gotten wedged. It might have shown up as /dev/sda* on some of those interim reboots, depending on whether there were any other usb storage devices present. "lsusb", and the tail command Eric suggested, are your friends. What is sda currently? [ these work on 2.6.23, not sure about earlier kernels ] $ cat /sys/block/sda/device/model $ cat /sys/block/sdb/device/model Anyway, glad to hear it at least works again. -Jamie

Hey Gang, Has anyone else noticed that proftpd seems to be off the map now? I've tried going to their web page to check for latest version / bug fix and I can't seem to get there...

Hello from Mark McLaughlin
by Markus 06 Mar '08

06 Mar '08

Hello, my name is Mark McLaughlin, I started a computer club in Hudson which extends to Marlboro. I hooked up with you because I am very interested in KDE 4 and want to learn more about how to make linux work for me since I am a writer/enthusiast not a programmer. I am getting better at GIMP and re-learning my MS Office skills with OpenOffice, but, I like to learn inkscape, scribus, do more with KompoZer, and do some multimedia as well I could use advice on how to make my computer club function well and if my club and yours could mingle a bit here and there on occasion when Fedora 9 and KDE 4.1 finally is available. I love Fedora, I feel it could catch up to Ubuntu and maybe surpass it with some new features. IMHO, Windoze XP will be the last good Windoze OS for sure, Windoze 7 has to be able to function like linux in order to survive... Mark McLaughlin hudsoncomputercrew.wordpress.com Hudson, MA

Scheduler Program mentioned in meeting

Hi all, Yeah, I'm still *in* the meeting. Glory be to laptops. I'm building a PyGTK scheduling application. It can be downloaded at: http://cons.truct.org/projects/psyched.html Release 0.1.0 is usable, but I suggest using the SVN trunk - it's better. I'm probably going to be releasing 0.1.1 in a few weeks.

Fedora Disapointment
by dulsi＠identicalsoftware.com 12 Jan '08

12 Jan '08

I understand that my laptop is old. Every time I've upgraded Red Hat/Fedora, I've liked the new system until Fedora 8. I didn't always upgrade. I skipped Fedora 7 since the live CD didn't boot on my laptop but Fedora 6 ran great. Fedora 8 is a dog with my small amount of memory (256M). I'm thinking I'll buy more memory but it disappoints me that Fedora runs poorly with 256M. (I would buy a new laptop but I'm just not impressed with the current offerings.)
