Problems with CD-Writing
by Jonathan Dye 24 Oct '02

24 Oct '02

Hi guys, I'm having problems writting CD's (It is an IDE cd writer Acer 20 10 40 soemthing) under linux (debian3 kernel 2.4.18). I can't seem to write a CD without getting errors on it (i.e. a diff with the orginal show differences). What seems to be happening is that I'm getting buffer underrun on the drive as it stops writing momentarily. I can't see why as I have cdrecord's fifo set to 16Mb and it doesn't drop below 90%, the writer is on it's own channel and even if I did get under-run the drive is supposed to have BURN-Proof which according to cd-record is switched on. I've tried slowing down the writing from 20x to 8x and still got a bad write (although I didn't notice the drive stop writing but I didn't watch for the whole 10 mins). I've also tried turning DMA on and off by using hdparm on the /dev/hd* entires (which seems to work even though I'm using ide-scsi) and turning it off means I can't spool data quick enough for 20x anyway. I was hoping someone would have a suggestion as to what I could do to stop this happening (appart from buy scsi!). I'm currently compiling the kernel with less crud and the preemptive patch to see if that improves the situation.

strange processes
by Jenny_Hopkins＠toby-churchill.com 24 Oct '02

Hullo List, I've just checked the processes running on my server and discovered a huge stream of the following, one per day: root 4643 0.0 0.5 1760 664 ? S Oct20 0:00 /USR/SBIN/CRON root 4644 0.0 0.8 2028 904 ? S Oct20 0:00 /bin/sh -c test -e /usr/sbin/anacron || run-parts --report /etc/cron.daily root 4645 0.0 0.3 1252 348 ?

However, I can't seem to kill any of the processes or unmount the nfs mount. I've restarted nfs-server and portmap. I can't umount /mntpoint , it says : Cannot MOUNTPROG RPC: RPC: Port mapper failure - RPC: Unable to receive umount: /ducati: device is busy It would be a shame to reboot the box as it has sat there running reliably and happily since last May. Thanks, Jenny.

browser spoofing
by tom potts 24 Oct '02

24 Oct '02

It looks as if IE.. can be set to spoof by modifying the registry under W$. A lot of the other browsers can be set to spoof by modifying their .cfg or .ini type files - either through the browser or editing the file itself. Opera doesnt as yet appear to have that facility so perhaps if anyone knows of an open source proxy it might be worth seing if that can be modified to spoof. On the downside.. http://www.mozilla.org/docs/web-developer/sniffer/browser_type.html seems to be able to work out you inside leg measurement!

*big* gentoo problem
by Adam Bower 24 Oct '02

24 Oct '02

Hi all, was using gentoo last night and did a emerge clean which should not remove any packages critical for operation of the machine and had it remove portage..... This has resulted in one very poorly box, does anyone have any idea how i could fix this? Is rpm included by default on the system? I can't check anything now as I am at work but I just wanted to read the docs to make sure I hadn't done anything stupid and now feel vindicated that I was not at fault. Anyhow if rpm is included in the base system would somebody mind building me an rpm of portage-2.0.38 please? If it isn't has anybody else got any good ideas? Thanks Adam

Fwd: Draft rules for discussion on a LUG list
by MJ Ray 24 Oct '02

24 Oct '02

Would people consider these guidelines worth adopting for the ALUG lists? If so, we'll add them to the web site. Date: Wed, 16 Oct 2002 22:25:52 CST From: Frederick Noronha <fred(a)bytesforall.org> Subject: Draft rules for discussion on a LUG list Just thought of sharing with you'll some draft rules which we find useful to implement and maintain the peace on our LUG list. If you have suggestions/ feedback, please pass them on. These rules were suggested, polished and put together by ShankarD, ArvindY, Siddharth, B2, Yunus, AshleyD and FN. #1. Talk politely on-list. If you can't be polite, please consider unsubscribing. #2. Please don't post any off-topic mail (non-GNU/Linux) to this list. #3. In your reply, quote only minimum relevant portions of the earlier mail. #4. Once a 'thread' is declared closed by the moderators, please don't insist on discussing it. #5. Personal mail, meant for just 2-3 persons on-list, should not be posted to everybody on the list. #6. Signatures and mast-heads should be of reasonable size. LOST tips, being informative and 'on topic' here, are welcome. #7. If material is available on the web, post the URL with a small description of the same. #8. Don't post only URLs without giving at least a brief idea of what the site contains. Some of our readers might not have speedy Net access. #9. Don't repeat the same posting more than once to this list. #10 If you find a good GNU/Linux-related newsletter which can be subscribed-to via the web, send in a brief synopsis of the newsletter and directions on how to subscribe to the same. #11 If you find something that would be of interest in a newsletter, send across the excerpts of the relevant snippets. Eg. a snippet or two from Freshmeat newsletter, rather than the entire posting. #12 Try to condense information and post. This is needed in view of the growing number of members on this list. #13 Rather than curse the darkness, light a lamp. If you feel this list could be better off with more useful information circulated through it, please post something that others would learn from. #14 Commercial postings (in moderate length), must necessarily go with the [COMMERCIAL] tag on the subject-line. Such postings should preferably be occasional, and not too frequent. #15 If anyone violates these rules (i) lodge a protest, if any, *only* with the moderators, and not directly to the list as a whole (ii) preferably send a copy to the person who's behaviour you see as violative to the letter and spirit of these rules. ########################################################################## # Send submissions for comp.os.linux.announce to: cola(a)stump.algebra.com # # PLEASE remember a short description of the software and the LOCATION. # # This group is archived at http://stump.algebra.com/~cola/ # ##########################################################################

Merchandise

OK, this is a bit off topic but does any one know where you can get decent Linux merchandise at a reasonable price, I am after a cuddly Tux amount other things, I don't seem to be able to find anything at a reasonable price. All URLs welcome! :o) I have tried www.linuxemporium.co.uk (very good for distros thou!). Apologies for the off list topic. Michael --- Outgoing mail is certified Virus Free.

Processor: Athlon 1.3Ghz RAM: 256Mb Motherboard: Gigabyte something or other with 686? chipset (I'll check tonight). It has a promise raid/ATA100 controller chip on it (which is supported by the kernel). I've tried the CDRW on this and the main ide channels. Hard disk is 16Gb which does ATA33 I think but don't know what make as I've not looked for a while (because it's worked fine for ages). Several more plays yesterday showed that simulations always seem to work OK. Writing seems to stop at random points through the process and I get a message which includes something about media being bad? (I'll grab the logs tonight). I've been using cheap CD's that I've had for a while so maybe they are dodgy, I also tried a different brand which didn't work although they aren't a known brand either. I'm going to get some better CD's today and give them a go. I managed to write a whole CD yesterday after I swapped the drives around on the IDE channels and turned on the always use DMA setting in my kernel. Although it wasn't the first attempt with the new settings. I've coming to the conclusion that it's my media that's crap. After I wrote a cd (or some of a cd) I looked at the cd under the light and I couldn't see the difference between it and a new, blank one. I'm sure you can usually see the track! I did discover that I had more luck when using Kreatecd rather than xcdroast but I don't understand why as they both use cdrecord under the hood. An interesting thing that I've discoverd about my drive is that it appears to stop writing and change speed at about 25% and 50%. Seems to be OK doing that though, guesss the burn proof is working OK. Anyway, I've got a few more things to try (media, different OS, different computer) and we'll see. > Adam JD _____________________________________________________________________ This message has been checked for all known viruses by the MessageLabs Virus Scanning Service

Re: [Alug] Fwd: Draft rules for discussion on a LUG list
by Ricardo Campos 24 Oct '02

My view on this topic is that a new subscriber should be pointed towards the FAQ, a link to a guide on netiquette, and perhaps one of those Newbie guides (i.e. don't expect an answer if you give no info). In regards to off-topicness, people seem to self-regulate and move things to social when things go too far off topic. Sometimes, someone sends a mail nudging them in that direction (let's take this to social guy/gals). I have only been on the list for a year or so, and self-regulation in general seems to have worked fine. And for headers, the FAQ sums it up. For newbies especially, their LUG is essential for them to start using Linux (how many times has a newbie said "I can't get my modem working????"), so perhaps their only recourse is to use work e-mail. Or perhaps they can't afford a landline/net connection. ALUG is the friendliest LUG I have seen so far since it (as a sort of egregoric entity) doesn't alienate people. Let's keep it that way! (And for those complaining about my linewrap- this is my last post from this (broken) e-mail addy :) ) My 2p.... Ricardo **Insert 10 line sig here** -- Powered by Outblaze
