I've tried to install linux mandrake 7.2 but when the installation procedure
starts to install the packages, I've some error with the package "tmpwatch".
I've tried with another CD of linux mandrake 7.2 but I,ve the same error.
I've tried to deselect this package but I can't beacause It's one of the
undeselectable package.
Someone knows what is the problem?
Thanks

This is also much less secure. A mistake in the Linux firewall
configuration or a bug in Linux lets others into the system. Given that
this is an existing Linux system we're talking about, chances are it's
being used for something, so it'll have lots of stuff on it that an
intruder would find useful. A dedicated hardware router, by contrast, is
easier to configure and therefore more difficult to MIS-configure, and
it has little or nothing on it that can be used by an intruder to do
more damage. Further, the dedicated hardware router can easily be left
on at all times; using a Linux box as a router requires that it be up
whenever the Windows system should access the Internet, which might not
be convenient.

I don't believe it can ignore the keyboard. What kernel are you
running? The keyboard driver is in the kernel and can't be intercepted
in software .. I think the kernel passes the requests somehow to the X
userspace driver, but I don't have a clue how. But I am fairly certain
that the userspace driver can't displace the kernel one. I thought that
the keyboard sends an interrupt and the code entered in the appropriate
interrupt vector location gets to treat it. That must be a kernel
bottom half handler routine (caveat: I am not and have no intention of
becoming a graphics programmer or expetr).

It's puzzling. sysreq is really low level.

Mmmm .. fortunately for you, microsoft have produced a version called
"windows for linux 2001" which runs in an x-nest window across x. It
provides authentic look at feel. Try and get hold of it at your local
walmart.
You can have any number of o/s's on your computer. Your question is
meaningless. They don't interfere.

No. Now it's entirely your own fault.
Upgrading modutils (and the rest of the stuff noted in the CCchanges
file) is all you have to do. Run depmod and be happy.

Use rpm2cpio.
Congratulatiosn .. now imagine what I had to do to reverse engineer rpm
when it first appeared years and years ago, with supposedly open code.
Yeah, code open, semantics obscured. Just to be able to read rpm's on

There's no need to patch the kernel; NTFS support exists in kernels
since sometime in the 2.0.x series, IIRC, if not earlier. Some
distributions (such as Red Hat) don't ship with NTFS support compiled,
though, so you may need to recompile the kernel, or at least that one
module.
Note that the NTFS read/write support exists, but is reportedly VERY
unstable, particularly with Windows 2000 (NTFS 5) partitions. In fact,
the 2.4 kernel detects NTFS 5 partitions and disables read/write access
even if you specify it on the mount command line. Read-only support is
much more reliable.

It means that the driver doesn't recognize the device. If you only have
a scanner connected, chances are you either don't have USB scanner
support compiled into the kernel, or the scanner isn't a supported
model.
Check on http://www.linux-usb.org for a list of supported hardware. The
last time I checked, fewer than half the scanners listed worked without
glitches via SANE. If you continue to have problems and post again, be
sure to include the make and model of scanner you're trying to use.

Subject: xplaymidi vs. AC97 V2.1 CODEC Compliant
Crossposted-To: comp.os.linux.hardware
Date: Sat, 10 Mar 2001 15:06:04 GMT
Hi,
My Linux system is composed of an Asus K7M mobo with an AMD Athlon CPU and
it is setup with SuSE-.70 Pro Linux distro. The audio hardware system is
based on the Analog Device 3D sound chipset (I believe the chipset is
AD1881) and it is an AC97 V2.1 CODEC compliant. I also have installed
rosegarden-2.1pl2 software and I would like to be able to play the midi
file while I am using the rosegarden to create/type in the notes. I
realized that the rosegarden software requires xplaymidi and my Linux
system does not seem to have installed a copy of playmidi software. A
search through SuSE' FTP site yielded nothing about playmidi source code.
Then, I found a copy of the playmidi-2.4.src.rpm source off the
ftp.redhat.com site and just downloaded, compiled, and installed playmidi
package. It looked just fine; however, when I tried to manually play a
midi song using xplaymidi, it complained "could not find the midi device"
even though I have manually told it to use /dev/midi, i.e. xplaymidi -D
/dev/midi song-title.midi. When I looked at the playmidi.c source code, it
does not seem to have any AD1881 chipset support. I am wondering if anyone
has managed to run playmidi on an ASUS K7M under Linux and would like to
lend his/her hand to help me out.
TIA.

Hmmm; yes or no.. not that it seems to matter in this case
since the partition fs 'seems' to be otherwise ok.
check man mke2fs:
Since 2.2 the 1+(8192*n) NOW means fewer alternate superblocks
for everyone out there who may have missed this switcharOOOOh!
The sparse_super switch is default ON and you get many fewer
alternate superblocks, depending on disk size unless you override
when making the fs. I didn't know this until just recently when I
managed to recover (thanks generous help) a large ext2 data
partition gone bad.
The general formula is still valid but does not imply every
multiple of 8192 anymore.
Are yu SURE that e2fsk restored the fs? If it did then you
might get at it (and to fstab) via some rescue. Worst case
scenario is a reinstall, but before that you might be able to
recover the partition(s) from another installation on another
drive or by putting it into someone else's machine.
Depends on what you have on there, don't give up too soon!

Right, since I use modules instead of recompiling the kernel I suppose that
those lines from dmesg are a normal conseguence. Then I try with 'modprobe
scanner' but still can't use XSane. lsmod gives me the following:
Module Size Used by
ide-cd 23632 0 (autoclean)
parport_probe 3428 0 (autoclean)
parport_pc 7464 1 (autoclean)
lp 5416 0 (autoclean)
parport 7312 1 (autoclean) [parport_probe parport_pc lp]
lockd 31176 1 (autoclean)
sunrpc 52964 1 (autoclean) [lockd]
ppp 20236 0 (autoclean) (unused)
slhc 4504 0 (autoclean) [ppp]
es1371 25920 0
soundcore 2596 4 [es1371]
usb-uhci 19052 0 (unused)
usbcore 42088 1 [scanner usb-uhci]
which I suppose should be fine.
I have only one USB device connected, and it is a HP Scanjet 3400C.
Can I tell from the above that my scanner is not supported? Maybe upgrading
to 2.4 would be useless, then.
Thanks for your kind advice
Federico.

I am currently working on the second variant (Matrox G450 dual head on RH7).
It is quite a hazzle.
According to Matrox you need first to install XFree86 4.0.2 (not included in
RH7 yet). Then get a new driver mga.o and install it.
You will have to modify the X configuration files.
I would be interested in any help on that myself.
