Well, what should the utmp file look like, the one in my /var/run/utmp says
a bunch of garbage which i can't even make out. some words like
reboot, tty, LOGIN, and thats about all i can read. the rest at strange
boxes, or signs, and letters, i even see a Yen sign. is this normal?
And how should i fix this?

Loading these deamons at boottime obviously presents a nasty security
risk. Is there an easy way of stopping my linux box doing this (pref.
without editing init.d files)?

Subject: Bru and cdrw
I am using the version of Bru that came with Corel linux. It works fine
except in one situation.
If I use this command line:
bru -cvvvv -s 640M -f - /home/* | cdrecord dev=3,0 speed=4 -eject -
it winds it's way though till it gets around the 650 mark and then bru
says something to the effect that "-" is not a directory, shall we
backup "-" y/n
If I press n, it just asks the question again, if I press y cdrecord
aborts and ejects cause the disk is full.
I am under the impression that I should be able to feed it another one
but the script or whatever it is bumps me back to the command line. Any
ideas?

my old CD reader id having trouble and needs replacement.
Is it wise to buy a new SCSI CD reader or is it preferable to
buy a DVD reader ?
I usually use SuSE Linux and they are now delivering Linux

Are there any caveats ?

I tied that using DOS fdisk but no effect. Might I have to do a low level format
? I've tried wiping the partition info completely but my kernel still autodetecs
raid 5 for some reason and then when I use the redhat fdisk I get it seems to
still access the disk via RAID. Can run the raidstop script because have not a
working mounted FS/libraries.
Any more thoughts appreciated.

Yes, you are correct. But does this really matter from the user's point
of view? As far as this user is concerned, a suffix and an extension
appear to mean pretty much the same thing. The poster was asking a
question about extensions and isn't making a distinction between
foo\0\0\0\0\0gz\0 and foo.gz\0 (or however they happen to be
represented). From the poster's perspective, it doesn't matter how the
name is stored, what matters is that gunzip does indeed care that it is
given a file that ends with ".gz".
Using correct terminology and understanding the differences is
important, but it is also important to answer the poster's question at a
level the poster can relate to, and a balance needs to be struck. I
don't want to see understanding the differences between FAT and EXT2 as
being a basic requirement for doing simple scripting in Linux. There
are times when using terminology loosely is good enough and useful.
(Hell, if I couldn't misuse "home page", "URL" and "login" as badly as I
do, I'd have a much harder time explaining a lot of Webby things to
novices.)

I just want to add that the Postgres docs are wonderful, a model
of their kind, very complete and well written. The only thing I
might grumble about are the Postgres JDBC doc examples (for
example, /usr/doc/postgresql-7.0/programmer/jdbc6519.htm) which
among other things discuss handling large objects. After a
little massage the code compiles but gives the error msg. that
this feature is not supported. (!)

if you have chkconfig you can do a 'chkconfig <daemon> off' for each
one.
Also you'll probably want to edit the /etc/inetd.conf file.

Do you have a URL where the image can be found?
That would seem to be easier than mailing a CD.

I had my first crash resulting in file system corruption today. After
running fsck, the /home/lost+found directory contains a file "#20422".
I looked at the file and found out that it was my netscape bookmarks
file. I looked at my netscape bookmarks file and found out it had some
other data in it. So naturally, I copied the file "#20422" over my
bookmarks file and everything works fine (at least everything I've
checked so far). Now I can't delete the file "#20422" out of the
lost+found directory. Is there something special I need to do?
Also, occasionally fsck complains about dtimes on inodes or something
like that and fixes them automatically. Is this something to worry
about? (I was going to cut-n-paste the messages, but apparently they
aren't making it into the logs.)

The limit on the number of IRQ levels has nothing to do with the Intel
8088, etc., architecture. It's strictly an artifact of the original PC
design. With proper MB and bus design there's nothing to stop them from
going beyond 24. Whether they can oveercome the inertia of the installed
bas, of course, is another matter.

Any time your know a box is cracked, you should:
pull the box off the network,
save any data,
save a full copy of the box for digital forensics,
refomat disk drives and
fresh install to remove any possible back doors the
cracker installed.

What some progams do is similar to this:
mkdir -p /tape/label/2000/Sep/06/14:13:54
touch /tape/label/2000/Sep/06/14:13:54/label
tar cvf /dev/st0 /tmp/label ./
rm -rf /tape/label
tar tvf shows the label directory first..
Season to taste.. for instance, if you do a 7 tape rotation
you can leave the last 7 in there, etc.
