Overriding NIS accounts
by Bill Mills-Curran Dec. 20, 2012

Dec. 20, 2012

I have an issue at my work with the configuration of one of our several flavors of linux servers. The goal is to override the NIS-specified login directory definition by using this syntax in /etc/passwd: +userx:::::/home/userx: +@grpx:::::: +:::::: /etc/nsswitch.conf has (in part): passwd: compat shadow: files nis group: files nis The distribution is Red Hat Enterprise Linux Server release 5.2 (Tikanga). If this was working I would get the following: > echo ~userx /home/userx Instead, I'm getting the login dir specified in NIS. I've successfully configured a Red Hat 6.3 server to work properly, but this one is driving me batty. Any suggestions? TIA, Bill

Possible intrusion?
by Bill Mills-Curran Dec. 17, 2012

Dec. 17, 2012

I was looking at the output of "last" recently and found several entries like this on my home server: userxx pts/0 c-24-91-141-172. Sun Dec 2 14:57 - 15:09 (00:11) (userxx represents my username) I did a reverse lookup on 172.141.92.24: host 172.141.92.24 24.92.141.172.in-addr.arpa domain name pointer AC8D5C18.ipt.aol.com. Looks like something from AOL. I got a little freaked, so I changed my password and also blocked that IP in /etc/hosts.deny. I'm not an aol user, but my wife is... but the "last" output shows this as connecting with my username. Any ideas? Thanks, Bill

Re: [Wlug] Using Facebook as a Website
by Steven Greenberg Dec. 14, 2012

Dec. 14, 2012

I don't think it is a question of Facebook or a website. Maybe the title of my email gave that impression. We can use both. Use Facebook for what it is good for (if that is anything), and use the web site for what it is good for. Creating events and managing RSVP might be something to leave to Facebook. Although, if we used one of the CMS software systems, it could probably do that job. For instance, I use my personal Facebook site only to have links to my blog articles on my web site. I agree, that I want to own the data on my blog. All my photo albums are on my own website. On the Facebook create group page there is an option to set privacy to: Privacy: Open Anyone can see the group, who's in it, and what members post. Actually, I suppose that may already be the setting. The description does not imply that you do not need to at least login to Facebook to see the group. /Steve -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.

https://www.facebook.com/SturbridgeForElizabethWarren does not require a login to Facebook. Facebook presents you with a login page, but you can just dismiss the login page to read the original. This is not true of https://www.facebook.com/groups/worcester.linux.users.group/ If the owner of https://www.facebook.com/groups/worcester.linux.users.group/ could open up access to this page so that you do not need to log in to read it, then this would be a great step forward. This facebook page ought to be mentioned on the web site. http://www.wlug.org/. That way, knowledge of the facebook page would not fade into memory in the archive of these emails. /Steve -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.

Examples of Websites Using Different Techniques
by Steven Greenberg Dec. 13, 2012

Dec. 13, 2012

I have examples of three different techniques that I have used for creating web sites. My personal web site is mostly hand coded HTML and CSS, with some custom Javascript and PHP. The drop down menus are pure HTML and CSS. http://www.ssgreenberg.name/ The politics link on my website takes you to my politics blog that uses Wordpress. http://ssgreenberg.name/PoliticsBlog/ I have my experimental website using Drupal 6. http://www.ssgreenberg.name/Drupal/Drupal/ the last example is the Friends of The Joshua Hyde Public Library on which I have used Drupal 7 http://www.sturbridgelibraryfriends.org/ I did a much more complex web site in Drupal 6 for a Square dance club, but that site is no longer available. I'll be happy to discuss the pros and cons of each technique. /Steve P.S. I have some Javascript which I use often for doing Outlines on web sites in HTML. http://www.ssgreenberg.name/SSGSoftware/OutlinesInHTML/ I also have some Javascript which I use to display all my photo albums on the web. One example is: http://www.ssgreenberg.name/Pictures/2011/10-28-Snow/index.php The software at the bottom of these pages that keep track of and displays the info about how many reads and readers there are for each page was also written by me and uses a MySQL database to keep the data that drives the display of information. -- Steven Greenberg Email: steve(a)ssgreenberg.name 251 Holland Rd.

Need some help with digital signal processing ...
by David Glaser Dec. 12, 2012

Dec. 12, 2012

Hi Folks, I need some help with an Android app for the hearing impaired. Essentially, the app is to be used with a wearable android device (Google Glasses or theSony android wrist watch) and will listen for sounds such as the door bell or the tty, or any other household soundthat should be reported to the wearer. Capturing the sound using an Android device is not the problem. What I don't know is how to compare the incoming sound stream with sound signatures that should cause the event to occur. Once the event occurs, then text can be displayed on the googleglasses or the haptic transducer on the wrist watch can be activated. This app is intended to be open sourceso I'm looking for volunteer help on the algorithms. I will do the programming. Regards David Glaser dglaser(a)glaserresearch.net

We've had half-completed plans since about 2 years ago to replace the hardware and software to create a Wiki or Drupal site to replace the outdated and manually-maintained-by-me HTML site. This week I plan to finally migrate things over to the new server, but the content will still be the old HTML site for now. We need some volunteers to help build a new site in either MediaWiki or Drupal or some other framework. After the meeting, we'll continue discussions over at Tech Pizza. Hope to see you there, Chuck

Has anyone made an ebook under linux? Specifically I'm taking about epub and mobi formats for supporting ereaders.

I still have to clean up the novel but assuming I finish that I'd like to convert it to ebook format.

help diagnosing PC issue: suspect power supply
by Brett Russ Nov. 7, 2012

Nov. 7, 2012

Hi, I'm trying to diagnose a home built PC running fine since 2007 but lately starting to act odd. Here are the system specs: Intel Core 2 Duo 1.8GHz cpu Asus P5B Deluxe mobo Nvidia 7900GS graphics card Kingston KHX6400 2x1GB DDR2 memory Sparkle ATX 400W power supply 3x 1TB SATA HDDs 1x SATA DVD-RW $ uname -a Linux spider 3.0.0-25-generic #41-Ubuntu SMP Mon Aug 13 17:58:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ cat /etc/*release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=11.10 DISTRIB_CODENAME=oneiric DISTRIB_DESCRIPTION="Ubuntu 11.10" $ uname -a Linux spider 3.0.0-25-generic #41-Ubuntu SMP Mon Aug 13 17:58:59 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux What recently changed: i) replaced monitor, last one died ii) (carefully) vacuumed the dust from inside. Kept hand on case chassis, didn't touch any PCB/chips, etc. Here are the symptoms: 1) first started seeing BIOS claims of bad CMOS checksum at boot time. Immediately suspected the CMOS battery, replaced it and reset CMOS settings but I continue to see this. This is the one symptom that I can't yet place, unless it's simply a bad replacement battery. 2) next started seeing the monitor fail to wake up after entering power save 3) powering on the PC shows issues: 3a) often the monitor won't wake at boot 3b) the bios often doesn't finish POST, gets stuck at splash screen 3c) bios settings often don't survive across power cycles (possibly related to #1--battery issue?) 3d) bios doesn't always give the affirmative beep (likely same symptom as 3a, 3b) 3e) a cold power on or reset can take several "tries" before the system stays on. I.e. fans will spin up, then spin down, one to three times before staying on. When this happens it's pretty much guaranteed that it won't boot successfully. 4) system will freeze to user input while up. I.e. once I get Linux booted, as long as I disable monitor power save it will stay running for a while, but I observed it stopped responding to KB and mouse input earlier this morning. Here's what I've tried: a) reseated both DIMMs, reproduced issues; tried with just one DIMM, repro'd; tried other DIMM, repro'd b) reseated graphics card, repro'd; removed graphics card (now headless), repro'd problem 3e c) reseated CMOS battery (CR2032), repro'd d) pulled all non-essential cables and internal connections, including power and SATA cables from all drives, repro'd e) updated BIOS to latest version, repro'd Unfortunately I don't have another ATX power supply to try, but was thinking of buying one. I might also try an old PCI video card, but I suspect due to repro (b) above that it's not the cause. Anyone have any other insights or agree it sounds like a bad PS? I still can't explain symptom (1), will probably buy another battery to be sure. Five years seems like an old PC, but I'm not a gamer so this suits me fine. Thanks, Brett

Monitoring for a network
by Eric Martin Oct. 24, 2012

Oct. 24, 2012

I'm trying to get a better handle on what's happening on my network at work. I'm currently using Nagios to monitor the big things (Server health, switch health, etc), but I'd like more granular statistics (how much data is coming and going, are any links saturated, etc). A quick glance shows that MRTG, Cricket, and RRD are good things to start playing with. I'm staring to play around with MRTG, but I'm hearing rumors of scalability issues and I don't want to get deep into MRTG if I should be putting resources elsewhere. A quick sketch of the network is a few internet connections, our router, and a few switches for networking along with a few switches for VoIP as well as our PBX. I don't want to monitor every port all the time, I instead want to monitor the uplinks of the switches to have a good idea, and look at the switch if something looks awry. My question to the group is, what do you use / recommend, and do you have anything that sticks out in your head about any of these packages (good or bad)? Thanks in advance, -- Eric Martin

I can do my presentation without the demo. 2. I can do my presentation next month, giving me time to get the demo working right, etc. What do you guys want me to do?
