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?

Core 5 DMA errors
by schwartz 31 May '06

31 May '06

Thanks very much for the help. I read the article and checked the IDE cables as instructed, and found a loose connection. I've booted Fedora a couple times with no error messages showing, so maybe it was the loose IDE cable connection. I hope so because I can't remember where I bought the hard drive and I can't find any sales slips for it. Bad Moon is Rising. Yuk! That was the first tune I had to learn on guitar over 30 years ago and I still can't listen to it without cringing. Yuk.

OpenWrt problem with tftp
by John Lange 18 May '06

18 May '06

I believe that I'm having a problem with the OpenWRT and tftp. I'm trying to fetch a file outside of the OpenWRT firewall using tftp but on the server side I see these messages: in.tftpd[26104]: tftpd: read(ack): Connection refused The client just times out. I suspect its a nat issue with the OpenWRT perhaps related to the fact the OpenWRT listens on a tftp port for uploads of firmware? Or is tftp generally tricky through nat? I can't see why it would be. Is there some kind of iptables parameter that needs to be added? Scant little comes up on google for iptables, nat and tftp. -- John Lange OpenIT ltd. www.Open-IT.ca (204) 885 0872 VoIP, Web services, Linux Consulting, Server Co-Location

Fedora virtual screen
by schwartz 18 May '06

18 May '06

Well, I can get a mild version of a virtual screen on my Fedora system on the GUI with Ctrl Alt - That's a minus sign after the Alt. The software screen is larger than the area of the monitor's screen and you can view the areas outside of the monitor screen by using the mouse. On the old Slackware distributions you could get a software virtual screen about 50 % larger than the monitor's screen. I found that useful and I miss it since neither Slackware 10, nor Fedora seem to have it. Or maybe I don't know how to activate it. I hope that explains it.

Segate 750G drives now available
by John Lange 16 May '06

16 May '06

Because it was a topic of discussion at the last MUUG meeting I thought I'd post that the Seagate drives are now available. I got a email from a supplier indicating: Seagate Barracuda ST3750640AS 750GB Sata $523.00 Note: that is a wholesale price and we do not sell drives. This is not an advertisement so please don't contact me to buy them. Its only meant to give you an idea of what the price will be when they hit the shelves. -- John Lange OpenIT ltd. www.Open-IT.ca (204) 885 0872 VoIP, Web services, Linux Consulting, Server Co-Location

Is there a way to get a virtual screen with Fedora? Is there someplace on the web that tells how?

Binding device names to MAC addresses
by Adam Thompson 10 May '06

10 May '06

Further to the discussion about binding ethernet devices to specific ethernet cards... I appear to have been mistaken - I cannot find any consistent way to tell the kernel to attach "eth0" to, say the device "02:01.0" (which in my system is: Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)"). If you use hotpluggable devices (e.g. USB ethernet adapters) then there may be a way but that's through the hotplug scripts, not through the kernel. However, the mechanism for mapping specific hardware MAC addresses to device names (eth0, eth1, eth2, etc.) is actually quite straightforward. /sbin/nameif (from net-tools) and /sbin/ifrename (from wireless-tools) both do the same trick, as far as I can tell. I have no idea how it massages kernel innards in this way, but whatever - it apparently just works. -Adam Thompson athompso-muug(a)athompso.net
