reboot ... really. D means uninterruptible sleep and while
you still can go on and use your system this one will not
go away until your machine goes down. Expect a "device busy"
during shutdown, nothing you can do about it.

So a Pentium II at 400 mhz will last longer than a Celeron overclocked
to 400? Whats the difference? Since Celerons are made from the same core
as a PII 400 why would this suggest it will burn out quicker?
I have a Celery 300A at 450mhz w/100 FSB and I had to take precautions
for the amount of heat it generates but my system temp is pretty low
even cooler than my old pentium II 266 with all the fans and stuff I got
in my new box. I had to bump the CPU voltage to 2.3 to get Linux fully
stable but other than that why do you suggest that it will burn out
quicker than a comparable Pentium II at the same speed?

Subject: ATX Power Off problem
Date: 26 Feb 1999 04:55:00 GMT
Hi everyone!
I have a dual-CPU motherboard with ATX power and it's been used
as a Linux server. I am using 2.0.36 kernel (the new 2.2.1 doesn't
recognize the 2 CPU's) with SMP just fine.
One big problem is that whenever we have a power loss
and when the power is back, the server doesn't power on. I have to
go right ahead to the machine and press the power button to wake it up.
I have play with the BIOS setup and it doesn't have any item
concerning this problem.
This is a big headache to me because I want it to be a 24-hour ready
server.
Is there any software or hardware solution to this problem
or should I drop this motherboard away?

I don't know much about the Linux-implementation in special;
but the "Who send's first" in IrDA (in this case in the IrLAP low-level part)
is completely independend from the higher level parts.
Announcing oneself via IR isn't so much power-intersive, that's why
it might be enabled by default. However, IrLAP defines low-power
sniffing methods for cases where power is critical.
Anyway, I don't think it is in this case.
Well, to sum it all up, you should be able to use IrLAN perfectly
without caring about who is sending the packets first.
best regards,
Christian

I guess by your suggestion that there isn't such a thing as a
distribution-making HOWTO? :) :)
Thanks for your suggestion. Doing something like that would
obviously be a very important part of my education.
However, your suggestion, while valid, is a little off-center. I
must have been unclear in my initial post, but I don't think anything in
particular is lacking in Red Hat, Debian or SuSE. I know I could simply
"add" to it. I am hoping that there are web links and documents that can
help educate me on the whys and wheres of "distribution design", if I may
coin that term. I guess I don't just want to take an available one and
plagarize it; I am actually interested in a deeper understanding of the
makeup of a distribution. And, what makes up the installation process.
If you can suggest things that may help there, I'd be grateful.
Thanks again.

Reply-To: [EMAIL PROTECTED]
Hello,
I don't really know where to post this, but this might be a
right place:
has someone successfully built ncurses-4.2 with glibc2.1
and egcs-1.1.1? Are there known problems?
I had no difficulties with gcc-2.8.1 and glibc-2.0.6 but I
want to upgrade.
The problem seems to be the generation of ncurses/lib_gen.c by the
shell script MKlib_gen.sh, using sed and gawk. The result
looks seriously broken. See the excerpt at the end of this posting.
What could be the reason of this? I'm using Linux 2.2.1, but I don't
think this matters.
Thank you and sorry if this is the wrong newsgroup. What would be a
better choice?

Subject: problem with creating ramdisk: kernel loads, but hangs when it tries to mount
ramdisk
Date: Fri, 26 Feb 1999 00:31:49 -0800
Hi,
I built a ramdisk root partition for redhat 5.2, but it seems to crash as
soon as the kernel jumps to the ramdisk.
The last message I see is:
VFS: Mounted root (ext2 fileseystem).
I built the ramdisk according to the instructions in docs/bootdisks
(followed it precisely)
Basically, I zeroed /dev/ram, made it an ext2 file system, and then mounted
it on /mnt.
I then created /mnt/dev, /mnt/etc, /mnt/bin, /mnt/sbin, /mnt/lib, /mnt/usr,
and /mnt/var
I populated dev with cp -dpR /dev /mnt
I then copied most of the /bin and /sbin binaries into their respective
locations. I issued an ldd /mnt/bin/init and copied all of the libraries
required by init. I stripped out the debug information with objmove from
the libraries and maintained symbolic links.
I then unmounted /mnt and copied the contents of /dev/ram to a file with a
dd if=/dev/ram of=rootfs bs=1k
It said there was a read/write error at this step. Not sure what caused the
error.
Could someone post a generic redhat 5.2 (intel) ramdisk root partition (one
that can be mounted by the kernel and contains basic binaries)? I would
really like to try a ramdisk that I know is working.
Thanks,
Oscar Stiffelman

Ok you are right is was not device.h

Subject: IP to process network interface?
Crossposted-To: comp.os.linux.networking
Date: Wed, 24 Feb 1999 19:05:03 GMT
Is there a way to get an IP network interface into the kernel so
that the kernel can operate on it as any network interface, but
have the interface really connect via a process on that machine?
Any IP packets sent to that interface would be given to the process,
and any packets that process produces through the appropriate API to
this facility, would "arrive" into the IP stack in the kernel. We
can assume the process will have root permissions to do this up, for
obvious reasons.
Does this kind of thing exist? I've looked at some of the various
features of Linux, and none seem to do _this_ (as simple as the
concept seems to me). The only option I see as an alternative is
to use PPP via a pty, but I'd rather avoid that, if I can, for a
few reasons.

If someone hacks you box he could
- install a new kernel (you might notice the reboot)
- install a new login program
- a new inetd
- hacked tcp-wrappers
- sendmail with backdoor
- <replace you favorite binary here>
And in fact he would do all of this.
A system where a hacker gained root access is insecure, no matter what
you try to do. Reinstall from scratch.
Just my $0.02,
Martin.
(Using monolithic kernels is IMHO a matter of taste. If it's possible
to build your kernel monolithic you don't have to store modules
somewhere, use insmod/rmmod/modprobe and don't have to do an
additional "make modules; make modules_install".)
