[Posted to man.unix.general and other news groups] ------ Forwarded Article <dk8aa3$hvc$1(a)canopus.cc.umanitoba.ca> ------ From gedetil(a)cs.umanitoba.ca (Gilbert E. Detillieux) The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting on Tuesday, November 8. The meeting topic for this month is as follows: Linux Clustering Mark Spencer, of Red Hat Canada, will be presenting on the topic of clustering. A brief discussion of the different kinds of clusters, as well as the reasons for implementing clusters will be shown. Come prepared to be a participant, as Mark likes to engage the audience in a more seminar style of presentation. 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, or in a lot across Ellice from IBM, for $1.00 for the evening. Indoor parking is also available nearby, at Portage Place, for $2.00 for the evening. ********************************************************************** 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".

Re: [RndTbl] wintv PVR 150 cards $99 at futureshop this week

If you'd like two tuners, check out www.ncix.com for the PVR-500 (now works with MythTV) for $175: http://www.ncix.com/products/index.php?sku=F25260&vpn=1081&manufacture=HAUP… Content-Type: multipart/alternative; boundary="------------010302010500050704060308" --------------010302010500050704060308 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit While it's still on topic, a quick run-down of the Hauppage cards for those unfamiliar with them: PVR-150 : a basic framegrabber. Requires more CPU cycles to do the MPEG encoding work. Works fine if you have CPU bandwidth to spare. PVR-250 : hardware MPEG encoder. Doesn't require much CPU while recording. (However, it takes *more* CPU time to transcode if you don't happen to like their choice of encoding format!) PVR-350 : hardware MPEG encoder *and* hardware MPEG decoder. Doesn't require much CPU time to record OR play back. Playback can be through the TV-OUT port on the PVR-350. Linux supports using the PVR-350 as a display device for X, but only as an unaccelerated framebuffer. In other words, it's really good for playing back MPEG video (in the same format as it recorded it in the first place) but really, really, REALLY bad for doing anything else like playing XMAME games or really, anything other than MPEG playback. On the other hand, the TV-out generates "perfect" resolution for your TV set, and you can theoretically run a MythTV box without a VGA card at all... The key point I wanted to make, is that although conventional wisdom says the PVR-150 requires the most CPU horsepower, that's not always the case. With the PVR-150 you can control what encoding format gets used - and you only have to encode once. With a PVR-250, if Hauppage's MPEG4 flavor isn't to your liking, the CPU has to *decode* and then *re-encode* the video in realtime - actually taking more CPU time than if you didn't have the hardware acceleration in the first place. The other point is that with the PVR-350, you'll get (reportedly) fantastic output quality but that for doing anything OTHER than watching MPEG4 playback, the performance will actually suck - and take lots of CPU time. -Adam Thompson Sean A.

burning DVD on OS/X Panther
by millward 19 Oct '05

19 Oct '05

First, I'd like to thank Shawn Wallbridge for the .PDF files. Great stuff. My question is for OS/X users. I won a Knoppix DVD door prize but since I don't have a DVD burner, I took it to my friend who has a PowerPC OS/X Panther system. To my surprise, his system failed to read the Knoppix DVD, so could not burn a copy of it. We think OS/X can't deal with the Linux file system, probably ext3. How do you get OS/X to recognize the ext3 file system and be able to read from it? Of course my assumption that a Knoppix DVD uses ext3 might be completely wrong. In that case, what file system are we dealing with and, again, how do I get OS/X to read it? I'm not too keen on buying a DVD burner myself since next year Blue-Ray and HD DVD will have arrived and made it instantly obsolete. I once had a programming instructor who refused to purchase his own computer for this very reason. I used to think he was nuts. Now I'm not so sure.

WRT54G, DNS, and DHCP
by Glen Ditchfield 13 Oct '05

13 Oct '05

I have a WRT54G with Linksys firmware (v4.20.7). It's set up as a DHCP server, and when I ask it to show me the DHCP client table, all of my computers' names are there. However, the computer names don't show up in DNS: 'slate' is listed in the DHCP client table, but 'ping slate' doesn't work. I thought I had seen web pages that said that the Linksys firmware could connect DHCP and DNS so that 'ping slate' would work, but I can't find anything now. I do find lots of pages about OpenWRT and dnsmasq... Have I been misremembering things? Is dnsmasq the way to go?

Adding second NIC - RH 7.1
by Raymond J. Henry 10 Oct '05

10 Oct '05

>From time to time, I have to UL a lot of stuff to my server (tonight, 12GB). Because of this, I'm wondering about dropping 1000MB NIC's into my XP system and the server, and running a separate dedicated connection between them. I don't want to spend the money to replace my switch, that's why I'm thinking separate network. I'm running RH 7.1 w/kernel 2.4.20-24.7. If I go ahead with this, I'm thinking the D-Link DGE-530T (http://www.dlink.com/products/resource.asp?pid=284&rid=879&sec=0) because of the price, and D-Link's indication it should work with my kernel. Anyone run one of these cards in a system similar to mine? Of course, I'd like this to be a painless as possible, so the other issue would be trying to have the existing NIC remain as eth0, so I don't have to mess with anything there. Any suggestions/ideas/flames?

Never used dd much. I got it to work half the time (my fault it didn't work the other half). If your laptop drive is only used for data (ie. you don't care about the image booting or you'd prefer a fresh OS each time) you can just use the cp command. I recall a few years back someone at one of the meetings was mentioning a ghost command for Linux.

creating image file
by millward 09 Oct '05

09 Oct '05

I'm trying to create an image file from a CD mounted in a CD burner /DVD ROM drive, but I keep getting error messages when dd tries to read the CD disk. I'm using the dd command: dd if=/mnt/cdrom of=/temp/my_image.img bs=18k or dd if=/dev/hdb of=/temp/my_image.img bs=18k My operating system is Red Hat 9 installed in hda9. The cdrom does not have scsi emulation. I removed that command from the Grub boot because I got worse error messages when it was in effect. The drive is defined in /etc/fstab as: /dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0 The error messages all look like this: hdb: command error: status=0x51 { DriveReady SeekComplete Error} error=0x54 Is there another way to create an image file from a CD without dd?

Re: [RndTbl] drive partitioning for Linux install
by Dan Martin 09 Oct '05

It turns out that my BIOS and ATA interface cannot handle HDs bigger than 137 GB, so I am switching my new larger drives to another computer and using its drives in the P3 - ie, lots of copying drives and partitions. The dd command has worked well, and saves me a lot of time compared to copying in DOS. Thanks. I have 2 other problems: 1) I need to copy a primary partition on one drive to a logical partition on another. I assume that if I do something like this: # dd if=/dev/hdc3 of=/dev/hda7 bs=1M that the boot sector of the primary will overwrite partition info in the boot sector of the logical partition, destroying extended partition info. Is there a way around this? If I create the logical partition with Partition Magic under DOS and copy into it, skipping the first sector, will that work? 2) I also installed Linux in my P4. When Linux complained it couldn't read the partition tables for sda, I let it rewrite them, thinking this was the new drive I put in. Instead, it was my serial ATA drive array. I have it configured to show up as one large drive under Windows. A large number of ATI video files were stored on the drive, which shows up in Linux as 2 drives (unallocated) and continues to show up in Windows as 1 drive - but now unallocated. The original drive was partitioned as a single FAT32 partition for the whole drive. My guess is that the data is still intact, and could be recovered if I put the right partition info onto the boot sector. Is there a simple way to recover this? If I created a new FAT32 partition in the "unallocated" space using Partition Magic in DOS or Windows, is that likely to recover the data? Also having some boot problems, but I think I can get around that. As a newbie, I'm getting into a little more than what Disk Druid can handle for me.
