This is a real concern.
Newbies really don't know what services might provide crackers with
doors into their systems, or they don't even know that it is possible
to crack a GNU/Linux system with a default install, or what a
"cracker" is.
It'll take a good deal of work and time before the post-newbie knows
how to deny external access via rsh, telnet and other sensitive
services and how to read the security documentation and install the
latest updates. It may take even longer time before he/she understands
*why* closing these services is a good thing, and why "system
administrator" is a real money-making job for many people.
Here, in Sweden, there is currently an explosion in the number of
people who have broadband (sp?) access to the internet. There's going
to be more and more GNU/Linux (and Windows and other) system connected
to the net for longer and longer periods of time. Installing a
GNU/Linux system that comes with "everything by default" will
definitely help you getting new and nasty friends.
Please also read "Clueless users are bad for debian" at
<URL:http://lists.debian.org/debian-devel-9903/msg02288.html> (I fully
agree with the author of the article).

Try out mpatrol at:
http://www.cbmamiga.demon.co.uk/mpatrol/
It is a dynamic memory allocation debugging library and can not only
detect memory leaks but also most common errors related to using malloc(),
operator new, etc. It also contains a memory allocation profiler along
the lines of what gprof does for execution times and can be linked in at
run-time without requiring a recompile or relink. I have no idea if it
works with RedHat 7.0 but it definitely works with RedHat 6.2 since that's
what I'm currently developing it on. And it's free!

That's tough to provide in an informal way, because newbies tend not
to trust others with details of their system. Maybe that's an effect
of M$ recovery, but usually the most that's possible is to steer
people in the direction of some resources. This is complicated due to
the fact the installed OS would be under "constant development"
if a new user had the expertise to make an accurate assessment of
what's possible, and what's not a good idea.

Subject: RPM-database & non-rpm packages
Date: Fri, 17 Nov 2000 11:26:08 +0100
Hi folks,
another question about a probably frequently discussed prob:
I�ve upgraded to kernel 2.4.0test10.
Therefor I had to upgrade some packages:
e2fsprogs
modutils
These upgrades were available only as *.tgz, not as *.rpm.
So I did an uninstall of the old (rpm) versions and installed the upgrades.
Now I�ve got the prob, that my rpm-database thinks, that these two packages are
not installed which leeds to the prob that I am not able to install some other
packages via rpm -U <packagename> due to failed dependencies.
Is there any possibility to force rpm to install these packages anyway or
better, to "repair" my rpm-database?
Any suggestions or pointings to related docs are greatly appreciated!
TIA

I would start off with either RedHat or Mandrake. RedHat is the most

I would purchase a CD if possible, it's a lot more convinent.

If you're sure you have the required files installed you can do:
rpm -Uvh <package> --nodeps

You probably won�t need mgetty, because isdnlog is able to react to specific
calls with certain commands (e.g. take the call and start pppd)
You also have to configure dialin via i4l setup (you can specify which numbers
are allowed to dialin and which not, if dialin is enabled or not and so on..)

Define HA is a hot standby server for you HA which does a failover in 2 of

The use failoverd, to me failover is that when a server dies all process

When on 17.11.00 I read a letter from Claus Atzenbeck

I decided to do war and invoked my tribal gods with:

I had a similar problem with a Realtek 8029 netboard. Sometimes the
computer just froze completely, not only under Linux, but also under
Novell and Windows.
The solution was to put the Realtek in another PCI slot, so it got
another IRQ. You can also check, if your Bios can assign IRQs to your
PCI slots and set the correct IRQ.

I think the problem is that you need to set the computer's hardware
clock with "hwclock," because "date" only sets the kernel clock.

You're off topic in this forum. We don't deal with networks, packets,
Linux, ports or kernels here. Ask in a Linux programming forum instead
(or in comp.sources.wanted).

I have a RealTek that I was able to use for IPforwarding to my Win98Box to

Unfortunately that was back before freewwweb filed under Chapter 11 and
is now owned byeither juno or netzero. I no longer have this access but
am still scouting for an ISP. I plan to keep that NZ anyway for a backup

Are there any other uses for the NIC? I think it only works whenPPP is
