"core" files contain information on the state of a program at the time of
an abnormal termination. The can be used by developers to troubleshoot
problems. If you are not planning on passing the core file to a developer
or using it yourself, it can safely be deleted.

Subject: RPM Database corruption :(
Greetings
My PC suffered a power failure recently, and since then it's been acting
up on me. I'm running RedHat Linux 6.1, and it seems that my RPM
database is completely corrupt. I can't add/remove packages, check
dependencies or anything.
Here is a sample output of what I get when I try to install a package:

While you are deciding on a distro (as has been mentioned, virtually any
will do and which one people end up using depends a lot on personal
preference, I use Slackware and SuSE) make sure that all the hardware
you have will work the first time. If you have a 'modern' PC then you're
probably all set but make sure that your particular video card and other
pieces are well supported. This will ensure a relatively painless
install and this kind of study beforehand will make the experience a lot
more pleasant.
Also decide how you want to partition the disks *before* you start
installing. I often sit down with a piece of paper and draw it up,
especially if I know that the machine is to run more than just Linux and
if I want anything more complicated than / and /usr, for example.

Err, well, yes, several gigabytes a day. You probably don't want to
know this.
Every day incremental changes since the last backup are gathered by a
central backup client served from the individual machines involved. Every
week a "full" backup is done to a different backup client. 6 weeks of
daily incrementals are kept. One month of weekly full backups. Every
6 weeks cdroms should be cut of the full backups, but it's a pain.
The full backups cover only the user home areas and the /boot, /var, /etc
directories. The rest of the systems are supposed never to vary, and
are md5summed every day. Any change in them is detected and repaired with
reference to a central site (and the central site is duplicated in all
the remotes anyway).
Each machine also backs up its own / partition every day using rsync
to /spare, at the other end of its disk. That's just for convenience.
It's really convenient.
The remote backups are done using find, tar, and ssh (plus gzip/bzip2).
It's a client/server script system. The tar stream is checksummed on
the way out and on the way in, and the sums must match, or the backup is
repeated.
If the receiving area overflows, an old backup will be discarded,
weighting by age and size to find the removal candidate.
Abstracting wildly, you might expect the backup client to run this
request:
ssh TARGETMACHINE "find /home -mount -type f -mtime -7 > FILELIST; \
tar culvTf FILELIST - | bzip2 -5" > BACKUP
(that's with serverside compression, leaving out the checksumming).
You want to look at cpio, really.
Another technique is to run a high-latency mirror. Say updated every
day or every week with rsync. The mirror earea can be a compressed
file system .. it's not bad compression with e2compr.

I disagree on both counts. Having the operating system source code
is a blessing. I'd rather read ten lines of code than a thousand lines
of documentation.
Secondly, I disagree that tasks accomplished through operating system specific
ioctl's are ``simple and common''. There is no need for something other than a
system management utility to be making the SIOCGIFADDR ioctl. People writing
system management utilities should have intimate knowledge of the operating
system.
This stuff needs to be hard to find and hard to use, otherwise people will go
rampant writing programs that depend on shaky semi-private interfaces in the
OS.

The ioctl call is not just for setting and retrieving parameters; ioctl's can
be used to perform synchronous tasks, such as blocking until something happens
in a driver.
The idea of replacing ioctl by /proc is absurd.

Subject: LILO 21.4.3 update
Reply-To: [EMAIL PROTECTED]
Date: Sat, 06 May 2000 22:26:27 GMT
LILO version 21 by Werner Almesberger has been updated to support booting
from large capacity disks using a new 'lba32' option (-L new command line
switch). Dubbed version 21.4, the source code is available for download
from:
ftp://metalab.unc.edu/pub/Linux/system/boot/lilo
Or from the developer's site:
ftp://sd.dynhost.com/pub/linux/lilo (developer's site)
ftp://brun.dyndns.org/pub/linux/lilo (an alias)
===========================================================================
The lilo-21.4.3 release adds the following:
1. RAID patches from http://www.elliott-turbo.com/lilo/lilo.raid1.also,
which go beyond the RedHat 6.2 patches in 21.4.2.
===========================================================================
The lilo-21.4.2 release fixes problems that have affected a few people:
1. The command line passed to the kernel was truncated at 78 characters if
the LARGE_EBDA (Extended BIOS Data Area) compile-time option was used.
(With today's big kernels, this was the default.)
2. If both 'linear' and 'compact' were specified, the second stage loader
would encounter disk I/O error 0x40.
Enhancements include:
3. The boot loader now understands octal. The kernel has always understood
octal, decimal, and hexadecimal, but prior boot loaders only supported the
last two.
4. All patches from the RedHat 6.2 distribution have been applied. This
includes the RAID support.
This version of LILO will boot from partitions beyond the 1024 cylinder
limit. To do this it requires a post-1998 BIOS with support for the EDD
packet call interface. Older systems may employ "soft" BIOS support for
these calls with hard disk boot software such as EZ-DRIVE(tm) or
MaxBlast(tm).

Hey, I don't mind! And it's not such a silly idea. I've just spent half
an hour looking for a delete_module function to match the
request_module one in the kernel. There _was_ a syscall to do it, but
nothing callable from driver code. I could have found that out in 1
minute with a man page for module.c.

Please do.
We need to find a way to reduce the inconsistency in /proc as well,
perhaps by creating a policy paper on directory structure and naming
conventions. Ideally a /proc/dev directory would contain directories for
each major number and each would be subdivided into minors. Master device
options (for controlling multi-port boards, for example) would exist as
named files in /proc/dev/{major}/, and per-device settings would be files
in /proc/dev/{major}/{minor}/.
We are half-way there with the current /proc entries for controlling
/dev/lp0, in that the /proc/parport directory is the base directory for
major device 6, and contains a separate directory for each minor. I can
set the IRQ of /dev/lp0 by writing a string-encoded digit to
/proc/parport/0/irq. By comparison, the /proc entries for tty devices is
a complete mess. I cannot simply read the status of /dev/ttyS0, but must
instead read /proc/tty/driver/serial and *guess* which line corresponds to
the desired port.
I would propose moving the /dev/lp0 settings to /proc/dev/6/0/* and the
/dev/ttyS0 settings to /proc/dev/4/64/*. Each should contain a "hardware"
file that outputs all of the information for that port, and a collection
of read/write files corresponding to the individual parameters.
In order to simplify programmatic access to /proc, we would probably want
to introduce readprocfs() and writeprocfs() methods to one of the kernel
libraries. That would allow a program to bypass the normal
open-errorcheck-read/write-close cycle and read or write a /proc entry in
a single step, as in:
int success = 0;
if (success = writeproc("/proc/dev/6/0/irq", "7")) ....

WOW!! I guess you were so inclined! and your right, I really didn't want to know but
thanks anyway!
Most of that went right over the top. I guess my goal of backup is a little primitive
compared to that.
Well, I'll look over the HOWTO and see what I can learn.
Peter, while I got your attention. Is there any reason that a normal user have access
to
the /usr and /var and /etc ..., etc directories other than the users own /home
directory?
If not how do you hide those directories from the normal user?
Also, I am trying to delete a normal user account using Linuxconf. I can't seem to
get rid
of the account. I cannot login with the account that I just tried to delete but it is
still
there in Linuxconf. It is just bothering me that in the user listing Linuxconf still
shows
that account.
One more question if I may, without getting into details which I understand might not
allow
you enough info to answer this but I have to login as root inorder to "turn on" my
sound
card. I've pointed an alias to a small script the runs several insmod commands to do
it.
When I log in as a normal user the alias runs the script because I inserted the alias
into
/.bashrc but the insmod commands won't run. Any suggestions? I guess ultimantly I
want the
sound card "turned on" when I boot up. How do I do that? Can the boot up process run
this
script or something?
Thanks

What clock speed and memory speed does that K6-2/500 use? The older K6
chips are not known for their fpu speed. When I went from P180 MMX
overdrive (200 MHz) to Evergreen K6-2/400 upgrade, my SETI@home times only
improved about 15% (~29 hrs). My PIII 500 laptop does SETI@home over 3
times faster (~8 hrs) and compiles a kernel more than twice as fast.

Note likely. I can definitely tell you that 96 meg works better than 32
meg, since it just about eliminates swapping.

By format I assume you mean mkswap? In Linux fdisk is hdb3 listed as a
swap partition? What does 'free' show for swap size?

You only need that for the real 'sh', bash has command line editing by
default. What did you do to mess that up, or are you really running a
different shell? Try typing bash and see if it works differently than
your login shell.

I am trying to find a version of seyon to run with RH60,RH61 or RH62.
Is there an RPM or tgz available?
