Excellent colors and resolution. Nope, need a PC for that unless you get some new fancy dancy camera w/ the feature. The ones with SD/MMC flash memory cards can be put directly into certain printers that will print w/out a PC. I was looking at some big screen TVs lately that also had SD flash and Sony Memstick slots to view pictures w/out a PC. For those you could bank on needing the unencrypted fat16 filesystem as they come form the factory. At least until world domination is achieved.

Win2k and XP will auto detect the drive, it is 98 that probably needs the auto installer software. ME may or not work the same as XP, but as others on this list know, I don't give a flip about the kludge that is ME. The reason Linux found the drive is the filesystem is plain old vfat (fat16). Not real efficient, but it works with everything and the drive size is small enough unless you get the 1GB and up drives that any performance loss of fat16 won't matter. You could repartition and give half over to ext2fs or any other, but if you still want to get to the drive easily under windows, leave part of it as fat16. Same goes for if you plan to boot to the drive. You didn't give it's size, so I can't be more precise. If you plan to encrypt w/ a Linux-based filesystem good luck. There is a ext2fs driver/program/reader/whatever for NT/2k/XP, but I've not used it. YMMV. It is likely to be beta. Actually NT won't even factor in the equation, because only one mfgr of jump drives makes a USB stack for NT. NT was unable to use USB unless you bought some add-on software. On the corrupt filesystem, just let MS run checkdisk at boot if it comes up and possibly correct the calculations on the FAT table partition sizes. QTparted can repartition disks just like Partition Magic, but there is almost always some complaint from Windows on the first boot after repartitioning w/ it. Let the checkdisk run BEFORE you actually put any important data on it. Just a friendly warning. I've been using jump drives and USB mass storage devices for quite a while now. One further warning, don't waste your time with putting ZipSlack in any form on the jump drive. Use DamnSmall Linux if you need/want to experiment w/ booting Linux from USB. Zipslack and those based on it have too many individual files and it takes forever to copy them over. DamnSmall and the Knoppix derivatives use the compressed filesystem and you are just copying one big file over basically. Anytime you are copying a large number of files to the jumpdrive, even at USB 2.0 speeds, it takes a long time. This is possibly a failing of fat16 showing. Brian Kelsay >>> "Brian Densmore" <DensmoreB(a)ctbsonline.com> 12/13/04 10:53AM >>> Anyone have one of these or something similar? I got one for my birthday, and immediately plugged it into my laptop and created a directory and copied some pix of my daughter to it. I noticed it had a file structure already on it along with some Windows and Mac software. I brought it in to the office to see if I could read the directory and sure enough it worked. It did complain about a corrupt file system. I also ran the secure disk software on it to repartition the stick as half secure and half not. My question, would it be possible to reformat the stick with an encrypted Linux fs and is so how would I be able to access it from Windows and Macs? Also, by securing half the card, will I still be able to use the whole stick in Linux? Another question, the stick has an autorun script for Windows, if I were to wipe the Windows software off of the stick would Windows still autodetect the stick and mount it? Or is it only autodetecting because of the autorun. I have a W2K desktop.

It's still cool. I've often thought about building a PC that doesn't use AC power. Most everything in a pc uses DC current. The only thing I can think of that uses AC is the PS, which: a) makes unnecessary noise and heat and all it really does is convert AC to a smooth DC. A good windmill or solar panel ought to be enough to power a PC. Could even hook up a bicycle to a generator, and thus get a workout while you surf! > > > > Brian Kelsay > > >>> David Nicol <> 12/12/04 11:48PM >>> > http://www.uclinux.com/hand-powered_web_server/ >

Re: knoppix question
by Brian Kelsay 13 Dec '04

It will boot into 128MB w/ no swap. It's a little slower at 128, but useable. 256 should be fine. I don't know what the low end ram is. One possible Knoppix problem is the large number of daemons that auto start at boot. Brian Kelsay >>> <lerninlinux(a)comcast.net> 12/12/04 11:37PM >>> I have taken old parts and assembled a test system, I would like to know if Knoppix will boot into 256 mb of memory only. No hard drive, no floppy. I am wanting to use it as a test station for hard drives, (checking if they are bad and fdisking and such).

RE: Secondary Slave
by Brian Kelsay 11 Dec '04

Some Western Digital drives I've had wanted to be on CS, especially if the only drive in the chain. I personally don't trust CS as far as I could throw it. It can get confusing which drive you are using when installing an OS or a new bootloader. CDRW drives like to be Secondary Master, but don't have to be. When they first came out for IDE that was a general rule to installing one though. Move the CDROM from SM to SS and put the CDRW on SM. Or put the CDROM on as PS. Can't remember which gives you better speed for CD to CD copy, but I imagine the best solution would be a drive controller and put em both on as masters. Brian Kelsay >>> "Brian Densmore" <> 12/10/04 10:58AM >>> I've had problems with setups like this: PM : HD PS : CDROM SM : none SS : CDRW [note this was by accident and I changed the jumper to make SS into SM to fix] PM : HD PS : none SM : present but not detected SS : CDRW [I fixed this by moving the CDRW from SS to PS] PM : HD PS : none SM : CDRW SS : HD [see above, also was able to fix by setting HD to CableSelect mode] I think the problems I had were due to a flaky HD. So the short answer is: no it's not just you. I think that some HDs are just flaky. What brand of HD was it? Mine was either a Conner or Seagate or WD. The PM being a Quantum Fireball. Of course it's also best to *not* mix HD brands, or even oftentimes product lines.

Quicker replies then I ever thought. Thanks all, found someone who has to pitch some (would prefer to do that then someones backup case) I appreciate all the offers.

SSH Timeouts
by Jonathan Hutchins 11 Dec '04

11 Dec '04

I'm looking for other people who are having trouble maintaining idle SSH sessions. Recently RoadRunner replaced our router at one location, and since then idle sessions lock up in three to five minutes. As far as I know, there was no change on any of the systems involved. SSH clients and daemons are largely set to default configurations. Sessions within the site do not lock up, and sessions between other sites still behave as expected. I AM NOT LOOKING FOR HELP READING THE SSH MAN PAGES! I am aware that there might be solutions in using UDP keepalive signals and other options, but what I want to do is confirm what's happened so I identify the reason and return things to their previous function. I am looking for other people who have EXPERIENCED this change, or who have heard about it happening to someone else. I want to identify what we may have in common with other sites where this has happened. Thanks, Jonathan

RE: Box stops communicating with switch on reboot

Which models? -----Original Message----- From: kclug-bounces(a)kclug.org [mailto:kclug-bounces@kclug.org] On Behalf Of Patrick M Sent: Tuesday, December 07, 2004 8:15 AM To: kclug(a)kclug.org Subject: Box stops communicating with switch on reboot Hi I have a couple of netopia routers with 4/8 port switches. When I take down my linux box and reboot, it won't connect unless I reset the switch. This in itself was livable I am the admin, I just have to remember to reset the switch or have someone else do it if I am not on site. Now, I reloaded an XP box on a linksys switch that is having the same problem. Is there something I am missing on this. do I need to open a port on the computers so the switches can see them easier? They end up working after resetting the switch, not something easy to do or remember every time you or your users reboot. _______________________________________________ Kclug mailing list Kclug(a)kclug.org http://kclug.org/mailman/listinfo/kclug
