Is there any other way to run scripts each day or each hour than setting it
up in crontab?
I have this linux-server at work, which has a few scripts running each
night. But I can't find them or where they are started from.

ive been hacked that way too, go to www.cert.org and find info about wu-
ftpd. he could have just edited the logs and put your friends ip there
because with the older wu-ftpd, its easy to get root access.

LUGOD, The Linux Users' Group of Davis, will hold its next meeting on:
Tuesday
October 3, 2000
6:30pm
The meeting will be held at:
Z-World, Inc.
2900 Spafford Street
Davis, CA 95616
The topic will be:
"Parallel Programming with MPICH"
presented by Nicole Carlson
Parallel Programming is the art of writing software which runs on
multiple CPUs simultaneously (ie, in a computer with multiple chips,
or using multiple separate computers over a network in a "cluster").
MPICH is a portable implementation of MPI (the standard Message Passing
Interface library). Message passing is the way in which separate
programs running in parallel can share information.
Nicole Carlson is a graduate student at UC Davis and works at its
Computer Security Lab.

schedules, etc., visit:

LUGOD is a non-profit organization dedicated to the
Linux Operating System which meets twice a month in Davis, CA.

I don't know the details, and I just last month finally threw away all
my old Byte mags :-( so I can't check. All I remember is that I read
the article and said "Cool: those UW guys are good!!"

Although this is generally true, there are two general exceptions,
where even ext2 filesystems make hard links to directories: the files
"." and ".." found in each directory are hardlinks to the current
directory and the parent directory respectively.

Yup. And that's why even at the best of times, hard links to
directories need to be strictly controlled. Ext2 is more strict than
some other filesystems.

Just try install the kernel package from Redhat's
SRPMS/kernel-xxx.src.rpm, and see all the patch files it comes with.
Some of these are patches that eventualy would end up in the official
next version, some not.

One more possibility is at. However, I think they are run from cron.
Do a grep for familiar strings from /etc/ and see what you get. On RH6,
there are /etc/crontab, /etc/cron.d, /etc/cron.daily, /etc/cron.hourly, etc.

The command 'at' can be used to tell a command to run at a certain
time. Or if you've been hacked the perp may have it's own 'cron'
program running.

The attacker might have cracked your friend's machine and used
that machine as a springboard. If this turns out to be the case
then your friend should immediately act upon this so s/he cannot
be held liable to any damages originating from his/her machine.

I think this may have been a security fix -- you don't want arbitrary users
bringing the machine to init 1. But it doesn't sound like it's working
correctly. Check RedHat errata.

Does anybody have a way to convert from the RedHat 6.2 RPM library
format (contents of /var/lib/rpm) to that used by RPM 4.0 shipped in
Pinstripe Beta? I ask because I want to see if I had a particular
package installed on the backup I made prior to the Pinstripe
installation.

Are you fit in shell ? Then check man pages for sh (or csh, bash), awk,
sed and cat. It will help you.
With these commands within a shellscript you can read data from
/etc/passwd and put them into shell variables, on console etc.
Sorry, actually there isn't as much time as I would need to solve
your problem by typing a little script.

Subject: Should mixer work with CD?
Date: Mon, 25 Sep 2000 00:02:47 -0700
I have the RedHat Pinstripe beta installed. I'm using gtcd (1.2.0), and
the XMixer (2.2) that ship with that release. I've got a SoundBlaster
PCI512 (emu10k) card installed, which seems to be working correctly with
the "play" application. I have the analog audio output of BOTH the
CD-ROM and CD-RW drives plugged into the CD and AUX IN ports on the
sound card.
Is there something I should be doing to hear the CD through the audio
card? So far, nothing I've tried works.
Please reply directly via e-mail, as my news is a little flaky.

Well, for one, there is no reason your hostname should still
be localhost@localdomain. You may be able to set the $REPLYTO
environmental variable to direct replies to a certain address,
but I would get a different mailer. I am a long time pine user,
but I think mutt is better (I just need to break myself of pine).
Both pine and mutt do what you want.
One other thing, if you do use sendmail, change your host's domain
to your ISP's, then you will need to strip off the hostname part
of the address in /etc/mail/sendmail.cf. You would also do well to
use the username your ISP gives you on your localhost as well.

You have to edit your $PATH environment variable. Add something like the
following into your /etc/profile to make it permanent:
PATH=$PATH:/this/is/the/dir/you/want/to/add
export PATH
This will keep your current PATH as well as add the new directory to it.
