I despise touchpads. I use a wireless mouse with my laptop. In any event, I used to have issues with touchpads under the 2.4 kernel. The 2.6 kernel has cleared up those issues for me. I would imagine a lot of backporting has taken place by now, anyway. Now, if we can just get NVIDIA to keep more up to date and do releases more often than once a quarter -- if that much. Back to the kernel -- what I'd like to do evenutally is build a 64-bit machine with perhaps 16Gbytes of ram, and make /tmp a ramdisk so I can store all sorts of potentially sensitive information there that I don't wish to keep on the harddrive, such as file caches and the like. Also, I want to eliminate the paging file altogether -- don't see a point for it when you have that much RAM. Are there any issues with having a kernel running without a paging file outside of giving you "extra" memory to swap out least-used pages? Also, are there any issues with getting 32-bit drivers to work in a 64- bit environment? Especially proprietary ones like NVIDIA? -- -Fred Your government delights in doing things "for" you.

In the driver sense, I originally moved to 2.6 because 2.4 was lacking drivers for GigE cards such as the Intel 10/100/1000 (which I believe has since been back ported). Also, the SCSI sub-system has been re-vamped to make it more secure and robust (and break cd writing in some cases). There is also the cryptography support. Gone are the days of having to patch the kernel for IPSec. As well as the usual refinements and fixes that one would expect to see in the newer kernels. However, there have been some issues. I had some problems with 2.6.8 and 2.6.8.1. But those issues were fixed two days later when 2.6.9 came out. FYI, Kenny signature.asc Description: This is a digitally signed message part

WPA, 802.1x authentication, etc. requires a few things in addition to the driver. Check out http://hostap.epitest.fi/wpa_supplicant/ for more info on that. > Are you using IPSec now?

Re: automount on debian help
To find out what's installed on a Debian
box, I often define this function:
function dlgrep() {
# dpkg list grep
COLUMNS=300 dpkg -l | tr -s '[:blank:]' ' ' | grep $*
}
...which you could use thus:
dlgrep -i autofs
dlgrep -i amd
If you have NIS installed you should (by convention) be
able to say:
ypcat auto.master

Although I'd agree it's an unnatural act, it's not unheard of for both to be running - my current workplace is the second one where I've see such weirdness. We're officially an autofs-oriented shop but we're running ClearCASE and the automounted-VOB trickery relies on amd.

It's important. If you can't mount the filesystem manually, you're never going to get autofs to do it for you... If you're not sure how to mount the files manually, the format is like this: # mount servername:/path/to/fs /path/to/local/mountpoint You need to know the path of the filesystem on the server, and you need a directory on which to mount the filesystem. Which raises another point: do your mount points exist on your new machine? Autofs normally creates the last part of the path for you... So if you have an automounted filesystem in /nfs/auto/blah, then on your local system, /nfs/auto better exist. If it doesn't, you're not going to get your files. > >What is the output of this command: > > > > ps aux |grep '[a]utomounter' > > > > Nothing So the automount processes either aren't starting, or they're exiting due to errors.

The Kernel version is 2.4 (as returned via the kernelversion command). Just a guess, you're probably using an IDE CD-ROM drive with SCSI emulation. Is this a burner too? That's a common setup for burners especially. That's not a problem - just important to know for troubleshooting. What does the following command yield at a command prompt: ls -l /dev/cdrom At the end of the line, you should see something like: "/dev/cdrom -> /dev/scd0" That would confirm the SCSI emulation (or real SCSI, but if that were the case, you'd probably know.). Running the command results with: lrwxrwxrwx1 root root3 2005-03-15 17:59 /dev/cdrom -> sr0 And yes, you are correct in thinking that it is also a burner. Plus trying out the uname command gives me .. 2.4.21-273-athlon (that was done just for grins. ) How can I easily verify this? I've run the update(s) methods and checked packages .. but can't readily determine how to verify that I have everything needed. Well, nothing would be using the disc except maybe the CD player. KSCD doesn't close when you "close" it. It minimizes to the system tray as a little CD icon. Right click on that and Quit to make sure it's closed. Other than that, nothing should be accessing the CD drive without being obviously in front of you. Dropping a audio CD back into the drive, the icon again changes, and using Konqueror to look at audiocd:/ I find this instead: An error occured while loading audiocd:/: The file or directory / does not exist. Here's my theory. If you go to the Control Center, then to the Sound & Multimedia section, and then the Audio CDs applet. There's an option here to "Determine device automatically" and it's probably set to /dev/cdrom. Depending on the link above being correct, to /dev/scd0, or being an alternate (and somewhat more common) /dev/hdd or /dev/hdc, this may be auto detecting incorrectly. Let's see what that link up there in the first part of my reply says and what it says here and see what we can do. Try setting this specifically to /dev/scd0 and I think you may find luck there. Test it by trying to visit audiocd:/ link again. I tried various different changes there .. turning off autodetection, /dev/cdrom only, or sr0 only .. none of these worked. Upon starting KDE (and the restarts just to see if that had any effect after changes) I see it doesn't recognize that there is a disk at all in the drive. If I eject and close with a music disk in, the icon changes to reflect that there is a music cd in the drive, but I still cannot access it through Konqueror or the terminal. Looking at /dev/sr0 with Konqueror shows that it is a "block device" which has me a bit stymied. Time to flip through the books again and see what that's about.
