Core dumps can be useful. If you have a program a.out that dumps core,
then you can do this
gdb a.out core
and you get the stack and state of the program.

You should be more patient about reading man pages. Sometimes
they don't suffice, but for utilities like chmod and chown they
are adequate. You might also want to try some experiments to
see how they work.
You could also consider using info, although it just might give
you the man pages again. Start with just
info
which will give you a short tutorial on how to use info.
Then you can access a given topic from the top level or go
to it directly by giving it an argument as in
info chmod

Yes. Linux is pretty stable, but occasionally, it will reboot
spontaneously. This is usually hardware related, but sometimes
subtle software problems can do it. On one Linux machine,
we accidently removed the user xfs (for X font service), and
the machine started rebooting spontaneously. It hasn't since
we fixed that, but the two things may be unrelated. We
have a Sun which periodically reboots spontaneously, but we
have not been able to figure out why over the course of two
years, despite many efforts.
> 1. How do I find out the cause?
Others may suggest some standard things to try, but often
there is no way to track it down. Let us know just what
the log file shows, and perhaps someone will have an idea.
> 2. Is it possible that I'm getting hacked by bored engineers at my ISP?
It is possible but unlikely. Of course if you aren't adequately
protected, it is possible that someone else is intruding.
Make sure at the very least that you have limited access with
/etc/hosts.allow and hosts.deny. Others will have other
suggestions that are more certain to repel invaders.
Also try turning off your network interface when you are not
using it to see if if ever reboots when the interface is off.
If it only reboots spontaneously when you are connected to
the network, that doesn't in itself mean you have an intruder.
It could be some hardware issue involving the interface.

Date: Thu, 05 Aug 1999 02:29:51 +0200
forgive me, but I can't see the point:
/bin/mount is r/x by everyone and /dev/scd0 is rwx for everyone.
this is ok, /dev/cdrom is just a --> link to /dev/scd0.
fstab says to mount /dev/scd0 (you could also say /dev/cdrom) to
/mnt/cdrom with fs=iso9660, _not_ automatically at boot-time, read-only
if done, and every user is able to do so (don't care about the following
0 0, that's special).
assuming the directory /mnt/cdrom (rwxr-xr-x root root) exists, you can
mount your cd by just typing
----zip----
#>
#>mount /mnt/cdrom
#>
----zip----
btw, to my knowledge these files etc you mentioned are owned by root,
but group should not be users but root also. what distribution do you
use and is this root/users permanent on all files ?

If the two systems are on the same computer, and your Linux
system can see your NT partition, then all you have to do
is mount it and cp the file to your Linux partition. But
it may be that your Linux system can't see the files in the
NT partition, or they may be on different computers. In that
case, the only way to do it may be to copy the file or files to
a floppy and then copy them back. Under Linux the proper
way to do this would be with mtools. If a file is too
large to fit on a floppy, you will have to split is somehow.
I don't know offhand how to do this with NT, but I am sure
it is possible. After copying the split sections back to
Linux, you can reassemble the file with cat.
If your machine has a zipdrive which both NT and Linux can
access, it would be simpler: copy to a zipdisk using NT
and copy back using Linux.

I want to send mail out from my computer at home? I don't have my own
domain name and domain address. When I send out mail to another user
on my local machine, it works. But when I send mail to the outside
world, it fails. Here is the relevant part of the returned message:

How do I fool sendmail into thinking that my domain is not
localhost.localdomain but rather uiuc.edu.
I see a danger though. If I could do this, then I could fool the
internet backbone into thinking that I am someone who I am not, and
I should not be able to do this.
However, with 'pine' I could do just this.

hmmm...I've never noticed that (I hate csh). I'll have to think about

You should learn how to read. I only commented on g++ which is

If so why are you defending that old garbage g++?
The only complaint I've ever had about gcc is that on both
Linux and OS/2 it is slow as hell. It doesn't show as much on
a fast 686 but it sure crawls on a 486. In comparision IBM C set
and Borland C++ fly.

Search the web if you need to know the details. The classes that
created core dumps were the IString classes from IBM's Open class.
I compiled the same classes under Borland on dos, winblows and OS/2
as well as under IBM C++ compiler under winblows and OS/2. The
only thing I had to change with Borland was the long long which weren't
supported. I solved the problem under Linux by removing the virtual
declarations from the routines that has a fixed pointer generated.
<rest of ranting and insults removed>
Next time before you try to start a flame because your favorite
compiler got blamed for its bugs do a bit of research.
Get a life!

The problem is that 'man chmod' == 'man 1 chmod'. This man page does

'man 2 chmod' gives a different slant (different man page author?), that
might be a little more compensable. 'man 2 chmod' gives a nice

Archiving to another hd partition?
man cp
Use the -a option to get an archive copy of any subtree of the
filesystem. Be careful not to include the archive destination in the
source hierarchy. Keep in mind that you don't want to archive /proc.
I recommend using the -x option to limit the source to a single hd
partition and archiving each partition separately.

dir is a convenient alias for ls. ls takes a zillion options -- check
the man page for details on all of them. Amongst them are:
-s size in K's (1024 byte units)
-l permissions, owner/group, size in bytes, date (see -c and -u),

Tar is a bear -- a zillion options too. I use the

cp -fv /home/BackupLists/BackupDates
/home/BackupLists/BackupDates.todays
tar --create --verbose --listed-incremental

.
tar tvf /dev/st0 |& tee /home/BackupLists/week$1.list
mt -f /dev/st0 offline
I have a SCSI tape drive, /dev/st0.

#!/bin/csh -fe
cd /
echo 'Insert the "main" tape, hit ENTER when read'
set ans = $<

When bash terminates, it send the SIGHUP ("hangup") signal to its
children. The default behavior is for processes to die when they
receive SIGHUP. You can try to induce them to ignore that signal
by running "nohup prog_name &" instead. (See the nohup man or
info page, however, because it can mess with the process's
standard output or error.)

Thanks, Leonard and other folks who helped solving my problem. I have three
further (perhaps silly) questions:
(1) If all linux partitions (except the hosting extended partition, of course)
can be logical, what is the rationale or advantage for creating a primary
partition in the first place? For example, if I want to fit the root partition
below the 1024th cylinder, I can create an extended partition first and use
fdisk to allocate the cylinders for a logical root partition. There is no need
for a primary partition.
(2) Just want to confirm ... . What MUST reside below the 1024th cylinder is
actually /boot but not /, am I correct?
(3) Another confirmation. The 4-partitions limit means in each IDE hdd, the
total number of (linux or DOS, whatever) primary and extended partitions
cannot exceed 4. Am I correct?

Well, I already deleted the extended DOS partition ;-) Now the Win98 boots up
very slowly. I don't know why :-<
BTW, what is meant by "expansion"? To enlarge the size of the root partition
(expanding the partition size)? Or to install more software (expanding
functionalities)?
Cheers, Hankel
