Sorry for being obscure on that point =) I was indeed referring to the
possibility of a cracker accessing and/or modifying your data. While
I'm not terribly familiar with python, it is generally a good practice
to present the most minimal external interface possible to your CGI
modules (to minimize exposure via buffer overflows and especially SUID
programs).

The benefit of using cron would be that you could set up a job to run
every 5 mins. or so, check to see if your server is running, and restart
it if it is not. This could be accomplished by using 'ps' and 'grep'.
If you don't need a "high availability" setup, this is probably
overkill.
There is a solution if you just want to run this from the command line.
The problem you're running into is the fact that when you quit your
shell, it sends a termination signal (SIGHUP?) to all of your processes
associated with that shell. The exact workaround depends on your shell
- essentially, though, you need to remove the process from the job list
associated with that shell. The syntax depends on the shell you use; in
bash, for example, you'd put the process in the background and then type
"disown <pid of server>". This will allow you to exit your login shell
without killing the process. Check the 'job control' section of your
shell's man page if you don't use bash =)
HTH,

Subject: How do I figure out which module to install
Date: Tue, 07 Mar 2000 22:42:47 GMT
I'm trying to get the ISC DHCP server to work with the current Debian
distribution. After installing it, I get the message that
the "protocol is not available" and that I should make sure that
CONFIG_PACKET and CONFIG_FILTER are set in my kernel. I don't want to
have to do a kernel re-compile. Is there a way to figure out if those
values were compiled as modules? And if they were, is there a way to
determine which module I need to insmod? None of the descriptions in
modconf look promising.

I know Windows 98 pretty well, and recently installed linux on my system
at home just to play around with. I really don't have a serious need for
it, but I'd like to learn it because it is supposed to be a much better OS
than Windows. Does anyone have a good recomendation for a book that can
give me a good overview of the basic functions and how to use them.
Thanx in advance.

Some distributions of Linux allow any user to restart the system by
hitting Ctrl+Alt+Delete on the console. I'm not sure if this is linked
to kernel version or not.
If this doesn't work on your system, you can make a SUID wrapper for
shutdown (SUID programs execute as the owner of the binary - for
shutdown, you'd need an SUID root binary). chmod 4000 sets the SUID bit
(replace 000 with the RWX permissions you'd like to have on the file)

Let me rephrase that. I *have* heard great things about Corel. I even
gawked at the purty Corel KDE screenshots when they first came out. But I've
read some things which lead me to the conclusion that it isn't very good.
Not very good meaning Not Very Good in the way that Caldera 2.2 is Not Very
Good in my experience. Inflexible, simplistic, and unreliable. However, in
light of the fact that it's based on Debian, I've always found this a little
hard to believe.

However, that won't likely be useful for string searches, as it
is going to be full of back spaces and underscores between
letters. To do the job properly, run it through a filter like
col,
man file | col -xb > text-file
But, it should be noted that the premise this was based on is
not true, because you *can* do string searching in the text
displayed by the man command. Enter 'h' to get a help screen on
what can be done. The basic search commands are '/string' to
search forward and '?string' to search backward.

Not yet--at least, not without modifying the KDE source! This capability
will accessible without modifying the source in KDE 2.0 from what I've
heard. It seems like a big oversight on the part of the KDE team, but I
guess they had more important things to worry about....

_Running Linux_, published by O'Reilly. Runs about $30; they have
distro-specific versions for RedHat and Debian. Don't bother with the
distro-specific versions--you'll probably learn more with the standard
version. The manual that came with your distro is a good thing to read,
and the website below is a rich source of info:

Personally, I wouldn't let anyone but me have that much power over my

I find Manhattan to be *really* safe. But this depends of course also on

Or easier, at the LILO prompt type
LILO: your_kernel_name_here single
(hit "tab" to see which kernels are available)
then you get kicked right into a normal shell, and you can set a new
password for the root-user using "passwd"

open kpackage again, find the package you installed and then hit the tab
that says "files" or something. it will give you a listof the files it

Start Kpackage, find and click on the package that's already installed
in the tree window at the left. You'll see a description of the package
in the window on the right. This window has another pane which is a file
list of the install package, complete with paths. Click on the tab in

HLT is not an APM thing, it's been in since 386 days.
APM lets the kernel tell the hardware more about the state of the system,
for example, it can tell the hardware when the system really is idle, so it
can slow the clock, or do other things.
