Self-Introduction and LinuxGlobe Invitation
by Markus McLaughlin May 17, 2008

May 17, 2008

Hello everyone, my name is Markus McLaughlin, I am both a member of the Fedora Project and a Linux blogger with a blog at http://linuxglobe.wordpress.com. About 5 years ago, I became a fan of Linux but did not actually use it until I bought my first Mac, which was a Mini, I now use an Intel iMac and I run Fedora 9, Ubuntu 8.04, and openSUSE in VMware Fusion. I want to reach out to other Linux hobbyists AND writers who want to promote Linux. What I want to do with my blog is to add other Writers who want to both promote Linux and help those who don't know what to do with it, with columns. Hopefully, Red Hat, Novell, and other companies will want to help fund a major Linux Magazine right here in North America. I want to help fill a niche that needs to be filled and HELP those who can't afford a Windows/Mac computer have free tools, internet access, and an inexpensive used laptop/desktop. Anyway, if anyone here has any ideas on what we can do together to promote Linux in this part of Massachusetts, PLEASE contact me. Fedora 9, IMHO, is much better than Ubuntu, so please check out the Fedora site at http://fedoraproject.orgsoon! Onward and forward!!! *Mark McLaughlin Hudson, MA*

Debian/*ubuntu security bug and a question...
by Brian A. Dewhirst May 15, 2008

May 15, 2008

So, someone directed me at this bug report: http://metasploit.com/users/hdm/tools/debian-openssl/ I'm afraid my head spins a bit when I try to make sense of what corrective measures should be taken... has Ubuntu already rolled out a bug fix which will take care of the problem? If not, what needs to be done to fix my machine? Thanks, Brian

port security question
by Simeon MacMillen May 12, 2008

May 12, 2008

I'm trying to set up Echolink (amateur radio software) on Ubuntu (through WINE). My computer failed the firewall tests -the troubleshooting material recommended the following: Allow UDP destination ports 5198-5199 between Internet and PC in both directions Allow TCP (source port any, destination port 5200) from PC to Internet What security risks do I introduce by doing this? (Is it worth the risk?) Thanks, Simeon MacMillen P.S. I've been on the Wlug mailing list for a year, though I've only managed to make it to one meeting so far.

Meeting Topic Idea - MythTV
by joel d May 7, 2008

May 7, 2008

WLUG'ers, I have a meeting topic idea but very little knowledge of the proposed topic, MythTV. I have a DVR through my cable provider, Charter, but am unhappy with it's features and capacity. I am ready to buy a capture card, re-dedicate some PC hardware and commit to building a Myth box. I know this was covered back in 2003 by Tim Keller, but my lack of recall has me missing details of his excellent presentation. Any others think this is a good idea for a meeting topic? If so, would anyone indulge by presenting Myth with their knowledge, hardware info (PC spec and video spec) and setup & install details? Joel

-----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

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 April 6, 2008

April 6, 2008

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 April 1, 2008

April 1, 2008

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... I guess I'll be upgrading to vsftpd... Thanks, Tim. -- I am leary of the allegiances of any politician who refers to their constituents as "consumers".

Hello from Mark McLaughlin
by Markus March 6, 2008

March 6, 2008

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
