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).

Re: [RndTbl] Apache2 modules
by Kevin McGregor 08 Jun '06

08 Jun '06

I got it sorted out -- at least the compile/install process. I haven't tried the module itself yet. It turns out that the compile step (the first call to apxs2) ends up putting the .so module into ./.libs! This is the default for libtool, so that would be fine, except for some reason the next call to apxs2 (and libtool, indirectly) doesn't look there. Weird. So, I ran 'make' once to produce the .so, then moved the file manually from .libs to the current directory, then ran 'make' again, which completed the process. Also, I had to revert to gcc-3.4 from the gcc-4.0, which produced errors in addition to many warnings about signedness mismatches. Thanks to Sean and Stuart for the help!

MUUG Meeting, June 13, 7:30pm -- Agile Software Development Env.
by gedetil＠cs.umanitoba.ca 06 Jun '06

06 Jun '06

The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, June 13. The meeting topic for this month is as follows: Agile Software Development Environment Specialized and robust tools for Java development are available to the Open Source community for everything from source code control, to document management, to running your finished application. Weaving all these components together on a central development server for team of developers can be a challenge. These frequently overlooked components in the development environment can make or break your project. Where do you keep the information everyone needs to see? Who is responsible for maintaining it? How do you know if code you just committed to the repository has impacted someone else's? You are writing JUnit tests, but how much of your project's code is actually being tested? With the focus on developer productivity, how can you address all of these questions without adding to the burden of just getting code written? In this presentation, Steve Moffat will show us how one project is doing it. The group holds its general meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend. ********************************************************************** Please note our meeting location: The IBM offices, at 400 Ellice Ave. (between Edmonton and Kennedy). When you arrive, you will have to sign in at the reception desk, and then wait for someone to take you (in groups) to the meeting room. Please try to arrive by about 7:15pm, so the meeting can start promptly at 7:30pm. Don't be late, or you may not get in. (But don't come too early either, since security may not be there to let you in before 7:15 or so.) Limited parking is available for free on the street, either on Ellice Ave. or on some of the intersecting streets. Indoor parking is also available nearby, at Portage Place, for $3.00 for the evening. Bicycle parking is available in a bike rack under video surveillance located behind the building on Webb Place. ********************************************************************** For more information about MUUG, and its monthly meetings, check out their Web server: http://www.muug.mb.ca/ Also note that MUUG maintains two mailing lists, called "muug-announce" and "roundtable". If you're not already on these lists, we encourage you to subscribe now: http://www.muug.mb.ca/mailman/listinfo/ The "muug-announce" list is used for monthly meeting announcements (such as this one) as well as other important announcements of interest to MUUG members. The "rountable" list is meant to be a forum for follow-ups to topics discussed at the meetings, or for round-table-style discussion on other topics that come up between meetings. Of course, for this to be effective, we need to reach a certain critical mass. So, please subscribe, and stay involved! -- Gilbert E.

Core 5 DMA errors
by schwartz 31 May '06

31 May '06

I'm getting weird DMA errors on my Fedora Core 5 computer. The motherboard is an ASRock P4VM800 with 512MB DDR Celeron 2533 MHz Model 4 hard drive is a Hitachi 7K80 7200 rpm parallel-ATA 80 Gig. Fedora is installed on /dev/hda7 9.4 Gig partition ext3 The DMA error message shows up during big file, or multiple file, copying from one directory to another, and during bootup. dmesg shows this message: cd ..hda: dma_intr: status=0x51 { DriveReady SeekComplete Error } hda: dma_intr: error=0x84 { DriverStatus Error BadCCR } ide: failed opcode was: unknown Sometimes the error message shows up at one point in the boot process, sometimes in another. During really big copies, the DMA error message is quite frequent. I also have XP, 98SE, and Slackware on the machine but so far none of them have this error, or maybe they're not telling. Can anyone tell me how to deal with this problem?
