kernel driver vs module
by Mike Leo July 11, 2006

July 11, 2006

I am still having a hard time understanding kernel drivers vs module's in practical use: I understand a kernel driver, is a driver that Linus, et al, have coded into the kernel, so if i have a peice of hardware, and I compile a kernel with that device's driver turned on, then my device will work. If i build that kernel driver as a module, the driver remains outside the kernel, but still availible for use. As a module I can rmmod or insmod when i need to use the device. My foggy'ness comes from a few things. 1. if the driver is built into the kernel, will it show up in lsmod? 2. if the driver does not show up in lsmod, how do i know if its loaded? 3. weather it's a built in driver or a module, how do i associate the driver (or module) with a particular device? 4. if the device does not have a driver in the kernel, I cannot build a custom kernel to include it, nor can I build it as a module from the kernel source. So: 5. if I get the driver from the vendor, it will build a module for me, based on my kernel-source or kernel-headers??? Then what? again, see #3: how do i associate the module with my device? This is a general linux quandry, but this time i have a debian stable install and have inserted a QLogic HBA. lsmod does show qla2xxx, but it doesn't seem to be functioning as it isn't logging into the fiber switch. thanks mike

Hi All, I have a system where the cd drive insists on keeping the drawer open. I will close the drawer manually by pushing the button that closes it. Within seconds the door will open again. What would cause this? Thanks

looking for an old amd cpu
by Mike Leo July 6, 2006

July 6, 2006

greetings! I burnt out an amd CPU (my own fault of course...we all know how wonderful AMD chips are!)and am looking for a cheap replacement. It is for this motherboard: http://www.giga-byte.com/Products/Motherboard/Products_Spec.aspx?ClassValue… The current cpu is model AXDA2000DUT3C AMD Athlon, most likely http://www.cpu-world.com/CPUs/K7/AMD-Athlon%20XP%202000+%20-%20AXDA2000DUT3… however, if anyone has a replacement cpu that fits this motherboard and is willing to part with it, please let me know. Performance is not an issue, but working is a must! thanks mike

Upcoming Topics
by Mike Perry June 21, 2006

June 21, 2006

I had a few ideas kicking in the back of my head for a meeting topic. By no means am I volunteering to give a talk on this, however I thought it would be a good idea to toss out. </end-disclaimer> How about a talk on port forwarding? The talk could include tunneling via program (like the old school datapipe proggy) and more appropriately the finner points of SSH port forwarding. Other peripheral topics could be including such as: port knocking, alt mechanisms of ssh authentication, and X11 forwarding. Just a thought... Cheers, Mike

Filesystem usage

Hi there, I am curious on some statistics and I was wondering you could help me out. I'm wondering what the output of the following command is on your system: root@chao:/tmp# cd / root@chao:/# du --max-depth=1 -h 4.2M ./bin 253K ./dev 36M ./etc 336M ./lib 0 ./mnt 436M ./opt 0 ./srv 18K ./tmp 0 ./sys 743M ./var 3.8G ./usr 38M ./boot 22G ./home 900M ./proc 9.0M ./sbin 4.5M ./root 0 ./media 0 ./initrd 28G . The system I ran on above is an ubuntu desktop machine that hasn't been rebuild in over a year closer to a year and half. For comparison a relatively stock ubuntu machine I have looks like: 4.4M ./bin 103K ./dev 12M ./etc 167M ./lib 0 ./mnt 0 ./opt 8.0K ./tmp 0 ./sys 209M ./var 1.6G ./usr 19M ./boot 2.3M ./home 513M ./proc 9.9M ./sbin 260K ./root 0 ./media 0 ./backup 0 ./initrd 2G .

SoC's with USB host
by Jamie Guinan June 10, 2006

June 10, 2006

To follow up on discussion about USB capabilities, I took a quick look at which platforms support USB host (so you can plug webcams, etc. *into* it), $ cd linux-2.6.16 $ find . | grep ohci ... ./drivers/usb/host/ohci-s3c2410.c [ Samsung ARM 920T ] ./drivers/usb/host/ohci-sa1111.c [ StrongARM(SA1110) companion Chip ] ./drivers/usb/host/ohci-lh7a404.c [ Sharp ARM920T ] ./drivers/usb/host/ohci-ppc-soc.c [ Various PowerPC (Freescale) ] ./drivers/usb/host/ohci-au1xxx.c [ AMD (formerly Alchemy) MIPS Au1000 ] ./drivers/usb/host/ohci-pxa27x.c [ XScale ARM (successor to SA1110] ... Those modules are thin hardware-specific glue around the main ohci/usb kernel code. I think the gumstix is a pxa25x, and only the 27x supports USB host. Development boards for a lot of these are priced rather high for the typical hobbyist budget, from a few hundred $$ on up, http://www.embeddedplanet.com/products/sbc.asp http://dkc3.digikey.com/PDF/T062/0378.pdf http://www.hitechglobal.com/boards/ARM920T.htm It looks like Gumstix and routerboard are the cheapest available products in this class. And they're great, but hopefully in the we'll see more things aimed at hobbyists, with USB host capability. -Jamie

Problem with usermod

Hi All, I'm running ubuntu (brezzy), and I just shot myself in the foot.... I went to add my username to a new group, but forgot to include the other groups that I belong to in the command. The command I used was 'sudo usermod -G <new-group> <my-username>'. Now I only belong to <new-group>. That removed my username from the other groups I belonged to, including the admin group. Is there a way undo what I did? I do have a copy of /etc/group before the change. Thanks, -Chuck

Booting Mepis from USB cd rom
by Sean Flynn June 1, 2006

June 1, 2006

Just acquired a new laptop that doesn't have an internal cd rom drive, just a "d-bay" usb cd drive. I had been using Mepis on my previous laptop, and I enjoyed it. But the Mepis Live CD chokes when I try to boot from it. The cd does boot in other pcs, so the media is good. I checked my bios boot settings, but I can boot Knoppix and Ubuntu live cds. I figure that to get other Mepis booted there must be a cheat code I can pass, but my little bit of googling didn't help. Couldn't find anything on the Mepis forums either. Could anyone explain what's going on, or point me somewhere for more knowledge on it. I'd like to understand more how a live cd boots and what the difference between a usb cd and an internal cd rom drive are.
