Problem Reading DVDs
by John Lange 05 Sep '06

05 Sep '06

For some reason we have a stack of DVDs that must have been burned in some strange format. When I put one in my DVD drive the drive refuses to recognize it. When I try to mount it, it simply says "no media". What I would like to do is take a "raw" image off the disk, so I can try to recover it. Something similar to what would be done with "dd" on a hard disk. dd if=/dev/hdc of=/tmp/file But again, it just says "no media". Is there a way to "force" a mount or some other technique so I can read the disk? Or any other suggestions as to how to recover the data? John

Problems with Shaw?
by John Lange 29 Aug '06

29 Aug '06

Recently I have been experiencing problems with all of our customers who access our services through Shaw including my own home internet connection. These problems seem to be wide-spread throughout the city. While throughput speeds and latency have remained good, jitter has become a major problem. What this means is upload/download speeds would appear to be normal but applications that require real-time packet delivery are effected. At home I notice major problems with things like VoIP and gaming. A packet analysis using ethereal indicates major spikes in the "diff" values and jitter with many packets arriving out of sequence. This only happens on at the destination end, not at the Shaw-customer end. This is near impossible to report as a problem because the techs you get on the phone have never even heard of jitter and any upload/download test they get you to run will be fine because TCP is built to handle this. However, things like First Person Shooter games are now a complete lost cause. My question for the group is, is anyone else experiencing this problems? I'm trying to determine how wide spread this is before attempting to escalate the issue. Regards, John Lange

I just wanted to add a "me too". Strangely enough, I started playing some UT2004 again (after a 6 month absence) on the weekend and immediately noticed horrendous lag/jitter. It was really bad on the weekend but was a fair bit better yesterday and today. It wasn't just a jitter issue -- Shaw was dropping packets all over the place too, based on my ping tests. I use cricket for traffic monitoring and it's pretty clear packet loss and latency went to hell in the past week. The graphs represent traffic between 2 Shaw Extreme modems, one in Chazwood, one on Regent. http://tecnopolis.ca/transient/latency.gif http://tecnopolis.ca/transient/loss.gif Let us know how it goes with Shaw... the "Extreme" service is supposed to be FOR gamers and is advertised as having low latency, etc.

Simple HTTP server.
by Sean Cody 25 Jul '06

25 Jul '06

The HTTP protocol is so ridiculously simple yet usually implemented in a convoluted and complicated way (ie. Apache, IIS). If you ever wondered how a web server works but didn't care to read the spec (RFC1945) take a look at this 'simple' implementation in Perl., This is a basic web server, written as the basis for a component in an embedded project I'm working on. I've since decided to re-implement it in C (perl + chroot = annoying) but the perl version would be a decent instructional tool. http://bitbucket.ca/misc/www.tgz I've implemented the bare minimum you need to make a web server. The bare minimum needed is: GET <-- Standard 'grab me a document' or CGI with appending key/ values to the URL. POST <-- CGI without appending to URL For the hell of it... MIME types and Cookie support are also in there but only because they were easy. Just so it works 'out of the box,' I've included a simple site which tests most of the functionality (save for cookies, I know it works but too lazy to write a test case). Contents of the Tarball: www/www.pl <-- Web server... runs on port 8080 by default but open it up and take a gander. www/site/environment.cgi <-- sh shell script...spits out the current environment variables, ie CGI not in Perl www/site/cgi_test.cgi <-- Perl script, simple GET/POST handling. www/site/index.html <-- simple web page www/site/gibson_for_dummies.jpg <-- included in simple web page and proves MIME types are working. The only use for this thing is if you really wanted to know how a web server worked and didn't want the pain of dealing with the RFC or the Apache source. I've tried to keep the code as clean and clear as possible (I know at least one other person that could read and understand it). If you find the damned thing useful then feel free to use it however you want. -- Sean

opening an eMac
by schwartz 15 Jul '06

15 Jul '06

Can anyone tell me what tools can be used to open an eMac safely? No, I don't think a sledge hammer would be wise, though I'm tempted! And does anyone know if an eMac can be upgraded to USB 2 from 1.1 ? This is to connect an external hard drive.

Linux on WRT54G
by John Lange 04 Jul '06

04 Jul '06

Further to the topic of installing Linux on the WRT54 series of Linksys devices; Linksys has a relatively new device, the WRTSL54GS. Basically its the old WRT54GS PLUS a USB port! And yes there is a OpenWRT available for it. No more storage limitations; just plug a USB hard drive in or other USB type storage and you're off ! For those wanting to run Asterisk on it you now have room for voicemail. John

beagle-build-in core 5
by schwartz 16 Jun '06

16 Jun '06

There is no man file for something called beagle-build-in in Fedora core 5. According to top, this thing takes up 70% of my cpu time when it runs and it runs a long time. Anyone have any idea what beagle-build-in does? It runs the heck out of my hard drive and I don't like that at all, especially since I've just had to replace the hard drive due to that BadCRC problem I wrote about a couple weeks back. Any advice would be most welcome.

Just installed Fedora 5 - Want to install MPlayer
by Mike Pfaiffer 12 Jun '06

12 Jun '06

Some good things and some not so good things. Over all I'm not impressed, but there aren't enough problems (yet) to justify my going back to Fedora 2. Anyhow... I just recompiled MPlayer and at first it didn't like the compiler. I told it not to check the compiler and there was an error near the end of the "make" step. I did a quick check of the MPlayer site and it seems they've moved over to a new machine (without saying where it is). I still have a copy of Pre-7 from before. Has anybody been able to install/compile it for Fedora 5? If so, how? Is there anything newer than Pre-7? Have the codecs been updated? Is there indeed a new site or was I hallucinating as a result of being up until 4:00am the previous night? Do I have to go and get the binary rpm? I'll ask again at the meeting on Tuesday. Alternatively, if I get it working I'll tell everybody how (if someone reminds me).
