More than true!
The OP should use scp to transfer files, as direct root ssh/scp are
hopefully
disabled, just use your user to scp...

I saw this one coming, which is why I said it is not a security
threat. Believe me, the raptor firewall _IS_ keeping out the script
kiddies. As for not knowing enough to enable root ftp access, removing
root from /etc/ftpusers is not enough, but I got it working by altering
the following lines in /etc/ftpaccess:
deny-uid %-99 %65534-
deny-gid %-99 %65534-
But of course, a smart ass would rather suggest I don't know what I am
doing instead of offering a suggestion. :-)
While my own personal domain is not very secure, and could probably be
hacked in a couple of hours, I would not leave a hole in the firewall at
work.
To the other guy, Stu, that DID offer a suggestion, thank you.

In the Award BIOS's on my FIC and MSI MB's, you have to disable the sound

Subject: Custom-Class Installation Question?
Date: Sun, 10 Jun 2001 01:46:36 +0200
Hi!
I have two hard drives on my machine,
on the first hard drive i have "SuSE 7.1" and "Win98" and on the
other i plan to install "Red Hat 6.2".
I didn�t use the option to install "LILO" on the first hard drive.
Instead i choosed the option to create a boot disk to boot LINUX
and everything works just fine.
And now to the question
If i choose to install "Red Hat 6.2" on the second empty hard drive
does this remove all the other LINUX/Win partitions i have on the first hard
drive?
Or can i use the "custom class" alternative to avoid this to happen?
Is it possible to have three independent os systems on the same machine?
Thank's in advance

Hi-
I don't have that exact mouse. I have a MS Explorer Trackball which I
really like a lot. My trackball has two left buttons, a up and down
control, a trackball, and two right buttons. The right buttons can be
mapped to other functions. I have not figured that one out yet.
You can make a few changes to your /etc/X11/XF86Config file and get the
wheel working, I would think. I use imwheel; but I don't think its a
necessity. I also use debian unstable and am on X4.0.3. Here is the
relevant piece of my XF86Config-4 file regarding rodent activity:
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/psaux"
Option "Protocol" "ExplorerPS/2"
Option "Buttons" "6"
Option "ZAxisMapping" "4 5"
EndSection
I think you want to change the protocol line to the protocol your mouse
uses; perhaps imps/2? Not sure there. Be sure to include ZAxisMapping line
also since thats what maps the scrolling action for your mouse wheel. The
buttons line is similarly significant. I have been playing with a few
different protocols now and am trying imwheel with the explorerPS/2 protocol
today :)
I just searched on this mouse at google and found a lot of articles from
mailing lists; unfortunately, in a language I don't readily understand. It
appears though that the mouse works and you may just have to play around a
bit with the protocols or do some research on the web. You may also want to
take a look at the mouse configuration examples off of www.xfree86.org.
They are pretty helpful.

You probably have to do a little tuning for hdparm to begin to do its stuff.
Here is what mine does with some hdparm variables in a start up script:
mperry:/etc/X11# hdparm -Tt /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 1.20 seconds =106.67 MB/sec
Timing buffered disk reads: 64 MB in 2.83 seconds = 22.61 MB/sec
Now if I run hdparm /dev/hda, it shows this:
/dev/hda:
multcount = 16 (on)
I/O support = 3 (32-bit w/sync)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 4982/255/63, sectors = 80043264, start = 0
Playing with hdparm can be interesting though. I had to make a few changes
to a 2.4.5 kernel to get things truly working here. I am using twin maxtor
40g cheapo drives on this system. The wrong DMA switches can cause your
system to get DMA timeouts when it boots. It will finally boot after a few
of these but I was kinda scared there for a minute.
To look at a possible tuning scenario, check out:
http://linux.oreillynet.com/pub/a/linux/2000/06/29/hdparm.html
The hdparm command I run at boot time is:
merwyn /etc/init.d: tail -2 bootmisc.sh
hdparm -X66 -d1 -u1 -c3 -m16 /dev/hda
hdparm -X66 -d1 -u1 -c3 -m16 /dev/hdb
I won't add to the length of this post by telling you what each switch means
in the hdparm man pages :) I will add to play judiciously with this stuff as
it states in the oreilly commentary above.
By the way, X66 in the line above means (according to the man page):
-X Set the IDE transfer mode for newer (E)IDE/ATA2
drives. This is typically used in combination with
-d1 when enabling DMA to/from a drive on a sup�
ported interface chipset (such as the Intel 430FX
Triton), where -X34 is used to select multiword DMA
mode2 transfers. With systems which support Ultra�
DMA burst timings, -X66 is used to select UltraDMA
mode2 transfers (you'll need to prepare the chipset
for UltraDMA beforehand).
Be well!

I had a similar problem on my Dell Dimension 4100 with a Geforce 2
GTS/Slackware7.1/kernel 2.2.16/xfree86 4.03 - That error usually means (with
this particular driver at least) that the kernel module is not loaded.
Fabrice's suggestion of modprobe NVdriver *should* load the kernel module
and once it's loaded, you should have no trouble getting into X. Adding the
module to your startup script will avoid this (minor) inconvenience,
assuming you don't mind the extra half-meg driver lurking in memory...

cd /etc/pcmcia, and stuff that into the relevant network.opts file?

DAC960 support is in the Suse 7.0 kernel, and I assume 7.1 as well.

Thanks for the post. It made me reread man hdparm and this is what I got
with hdparm -X69 -d1 -u1 -c3 -m16 /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.93 seconds =137.63 MB/sec
Timing buffered disk reads: 64 MB in 1.79 seconds = 35.75 MB/sec

Works on my m/c I recompiled enabling "Advanced Power Management BIOS support"
as a module, also ticked (using make menuconfig) "Use real mode APM BIOS calls
to power off".
Loaded apm.o using rc.local (/sbin/modprobe/apm), checked it was loaded using
lsmod after reboot. The m/c (ATX) powers down correctly using the halt command.
There are certainly other better ways, but this works for me...

Linux Gurus,
Please help.
After I upgraded my system from RH 6.2 to RH 7.1, I found
that the login command is no longer working. I can't login
from the console as root or as other users.
Then I noticed that the /bin/login has not been updated
during the upgrade. When I tried to upgrade the util-linux
package, it fails because /bin/login cannot be renamed
or removed. I tried different methods (including boot the
system in rescue mode) and yet I can't remove the /bin/login
executable.
# rm /bin/login
rm: remove write-protected file `/bin/login'? y
rm: cannot unlink `/bin/login': Operation not permitted
# mv /bin/login /bin/login.org
mv: cannot unlink `/bin/login': Operation not permitted
mv: cannot remove `/bin/login': Operation not permitted
I suspect that my system was hacked with a bad /bin/login.
Anyway, how can I removed this file under ext2? I really
don't want to reformat my drive if possible...
thanks,
Dowson
