Yes, the source doesn't indicate anything like that. It tried ~/.pam_umask
and then the "system" umask, passed as a argument in the form umask=[N]NNN.

I find this package a bit maddening. It mixes hyphens and underscores in names,
paths, etc. Although I have to admit, I've never seen a Debian package name with
an underscore in the name, so if that's the constraint, it can cause confusion.

Do you need help?X

The documentation is lacking some detail too, e.g. only by looking at the source
would you know that the ~/.pam_umask file should only contain [N]NNN, and not
umask=[N]NNN, or some other form. Where does one make suggestions for
improvement? To the package maintainer?

Those were all good suggestions, but when I tried the last one and found the
umask set as I expected, I went hunting. I was logging in via ssh using public
key authentication, and UsePAM was set to 'no' in my /etc/ssh/ sshd_config
file. My fault entirely! Now fixed and working properly. But perhaps the
lively discussion found at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=314539 deserved another caveat.

Thanks for the pointers -- you saved the day!!!

I don't understand the point you're trying to make, unless it is to just give an alternate way to do the same thing?

Yes, the dd command given will also write zeros to the device. Same as the "cat /dev/zero > /dev/hdd" does.

And, both commands generate the same basic output error (different words, same issue):

   cat: write error [No space left on device]

   dd: writing `/dev/fd0': No space left on device

This is because 'cat' only knows to stop when input reaches EOF, which /dev/zero never gives, and dd will only stop if you tell it how many blocks to write, as in:

   dd if=/dev/zero of=/dev/fd0 bs=18k count=80

Can we help you?X

The error messages in the first two cases are simply the response of the disk driver to the fact that it has moved the read/write head to the end of the disk and can't go any farther, even though both commands try to.

Yes, "scanner" group on your computer. If you've got a scanner, there's almost certainly a group called scanner.

Have you checked what options the ethtool(8) command gives you? Compare the available options with the docs on the intel site.

I'd like to know what binary diff program you've been using in a production environment. I've been searching the WEB and I've found a few popular alternatives: * http://jojodiff.sourceforge.net/ * http://www.daemonology.net/bsdiff/ * xdelta3 (In Debian) The second one seems to need a lot of memory. About 850 MB for 50MB files (old and new). I think I might have to run some experiments, since the files I will make tests with don't change much. Regards, Nelson.- -- http://arhuaco.org

Here is what I did: with i8kutils installed, I ran make-kpkg=20 kernel_image on two diff. kernels. Fans behaved as expected and I=20 stayed relatively cooled. With cpufreq gov to performance the 2nd fan=20 came on at 48C on slow, and went to full speed at about 68C. I uninstalled i8kutils, rebooted and did the same thing in gnome (I=20 needed the sensor applet to "see" the fans). the 2nd fan showed speed of 0 until I got to 62C. The 2nd fan slowed=20 down at about 59C. I killed the two make-kpkg running and watch it slow=20 down. The 2nd fan went back to 0 at about 43C. At rest now with=20 governer to powersave (800MHz) I am running 40C or about 104F. I also kept my hand next to the 2nd fan exhaust port and my touch=20 confirmed the sensor readings (they might not have been accurate, had=20 that happen before). My conclusion: you don't need i8kutils if you are running a Vostro 1500=20 and Ubuntu. Probably will not need it running Debian as as far as I can=20 tell, the BIOS is running the fans, perhaps ACPI: I really don't know,=20 I never had to be concerned with what turned the fans on or off. =20 Anybody out there know? So, all those articles about Dell fans where either appropriate for an=20 earlier/different model laptop, or they needed not to be concerned about=20 it at all. Who would have guessed that that info was wrong, I mean I found it on=20 the internet, and you can always trust the internet, right? Anyway, HTH any of you out there. --=20 Damon L.

One more note on this "low level cpu": I was impressed! I had to=20 really really push this thing to get it to heat up. Running one=20 make-kpkg was not enough to push it to turn on the 2nd fan and the cpu=20 was only running at about 55% with the governor set to performance. =20 Kinda makes sense since this is a 64bit CPU and I was pushing 32bit code=20 around in a 32bit userland.=20 Any other Dell Vostro users out there with debian? Have you had any=20 issues with heat? --=20 Damon L. Chesser damon@damtek.com http://www.linkedin.com/in/dchesser

CF cards are sold everywhere. You want the long-life versions. Finding adapters may be a little harder, but mail-order is probably suitable. The internet is your friend here.
