Centuries ago, Nostradamus foresaw a time when Harry Lewis would say:

That's reasonably correct.

This, however, is distinctly not correct.
Gnome and KDE represent two things:
a) A set of libraries providing useful services for applications, such
as parsing configuration files, widgets to display things, and
interprocess communicatoins, just to name a few services;
then there are...
b) A variety of applications that use those libraries.
The notion of "running KDE" isn't a sensible concept; KDE is not
identifiable as a program.
The crucial thing is not the applications, but rather the _libraries_.
Unfortunately, the makers of Linux distributions have tended to muddy
the waters by trying to set up default configurations to set up X
"environments" that are tightly tied, often in a somewhat "partisan"
manner, to one or the other of GNOME/KDE.
The great confusion comes from the fact that differing distributions
set up differing schemes for starting up X (actually, that part doesn't
very much in and of itself), and THEN...
- Starting up a window manager;
- Possibly starting up other things like "panels" and other
application launchers;
- Loading information about the applications on the system into
menus and perhaps into the "panel"
There are some distributions that try to be at least somewhat neutral
about the window manager or about the "desktop environment;" Debian,
as case in point, has a utility that will generate menus of apps for
a fairly wide variety of window managers. And it provides a generic
scheme for choosing window managers.
Others are rather less neutral; Caldera towards KDE, Red Hat towards
GNOME.
_STRANGELY_, Red Hat has also been somewhat biased towards the
"Enlightenment" window manger. This is strange because:
a) Enlightenment is, of all window managers, the most hungry
of CPU and memory resources, and thus can hurt performance;
b) The author of Enlightenment left Red Hat a couple years ago
under a bit of a cloud, not on _great_ terms.
Other distributions have somewhat similar biases...
-> Red Hat, at one point, by default would install fvwm-95, with
a _REALLY WILD_ configuration scheme called "The Next Level,"
which involved a complex combination of M4 scripts; this was
_REALLY_ a pain to try to reconfigure;
-> Corel Linux biased towards installing a number of KDE-based
components, as did Caldera.
-> TurboLinux installed a Quite Sophisticated set of X environment
stuff based on running the AfterStep window manager.
-> SuSE once had a KDE-oriented bias, but I'm not sure that this
extends to doing massively sophisticated things with the
way the X environment gets built up when you run X.

Did you assign io-0x230 specifically to eth0 or eth1? I think that would
solve the problem. I'm still pretty knew to all of this, so I'm sure
someone will correct me if I'm off-base.

How much memory do you have? Netscape especially is a pig when it comes
to memory. Use xosview to graphically monitor your memory (green is
what is *actually* being used, not just buffered or cached), or 'free'
from the command line.

Tip 1: Remember to eat.
Tip 2: Remember to sleep (this is sorta optional for a couple of days)
Tip 3: If you have family, remember they exist and would like to see
you (hopefully :-).
Tip 4: Ditto for friends.
Tip 5: If you have pets, remember to feed them (and don't trade your dog
in for a penguin)
Tip 6: Remember those bills, you still have to pay them (unless you are some
super-cracker [then remember to run when you see the blue lights]).
Tip 7: Do not beat up friends or coworkers if they say Linux sucks (it is
OK to go into their Windows machine and change their shell back to
progman.exe [in system.ini] and convince them that you downgraded
their PC while they were in the restroom.) :-)
Tip 8: Remember that getting your coworkers technical books that you want
and they don't for their birthday is just like buying them a gift
and yourself a book at the same time.
Tip 9: Learn POOP (Perl Object Oriented Programming), this is impressive on
a resume. Your boss says: "You don't know crap do you?" and you retort:
"No, but I do know POOP!".

The number one fact to consider here is that whatever swap space
you do allocate, it is *free*. You already own it and are not
using it for anything else. Hence you can certainly afford to
be generious.

There are some other considerations. Linux buffers disk reads,
and uses otherwise unused RAM for that purpose. Hence the more
RAM you have available for disk buffering, the faster your
programs will generally run. Linux will also swap out unused
processes, making the space in RAM they would otherwise take up
available for disk buffering. Hence you do want _some_ swap
space allocated.
I have a system similar to yours, in that it has 256Mb of RAM
and often is lightly loaded. Here is what free says right now:
total used free shared buffers cached
Mem: 257972 242560 15412 30872 62268 62000
-/+ buffers/cache: 118292 139680
Swap: 315048 15928 299120
Which indicates that 16Mb has been swapped out, and is available
for disk buffering. (You can also get an idea how much swap I
might recommend. :-)
The actual virtual memory (RAM + swap) you *must* have amounts
to "more than the need for virtual memory will ever be". And
remember that if your vm use exceeds the RAM + swap total, your
system will crash. So the question is, how much vm could your
box possibly ever use? Since for _you_, swap is free... pick
some nice large figure that boggles your mind (if you had ever
bought a computer 15-20 years ago, just idea of having half a
meg of virtual memory is worth what it is going to cost you!).
(And if you use Netscrape, at some point the amount of vm it
uses will be all there is, no matter how much you have. In that
case you want enough that you'll notice it before the crash...)
In my case I occasionally do some heavy duty image editing, and
have actually seen this system use 400Mb. Hence I have more
than 500Mb of virtual memory. It rarely ever uses more than
200Mb of vm for processes, so I have 256Mb of that vm as RAM.

yes, that was exactly my point. i wanted inetd to start my

and then make the script start the intended service.

i tried using a simple bashscript to alert me and then start
telnetdaemon. didnt work. when telnetting in it did beep, but
then istead of getting the loginprompt i noticed that identd was
started, 2 processes. so i killed those. after 2 seconds 4
identd-processes were started. they basically took all cpu.

yes i understand that.
thats exactly why i put it in that file.
so that when the superserver gets a connection
on port 23 it would start my script (as defined
in /etc/inetd.conf) which would alert me, and then
the script would start the service.
or thats what i thought.
tried with a bashscript first, didnt work:(
perhaps the superserver must pass some info to
the pertinent service for it to work, which my script
clearly doesnt?

Subject: Hex editors?
Date: Thu, 14 Sep 2000 20:30:54 -0700
Can anyone tell me a bit about hex viewers / editors for unix / linux?
I do lots of internationalization work. I frequently need to see exactly
what bits are in a file, and I can't rely on a text editor's (or a terminal
emulator's) interpretation of those bits. Octal won't do. Neither will that
charming unix convention of displaying bytes as control-left elbow-type
keystroke sequences.
So here are my questions:
Is there any standard unix command line tool that will display a hex view of
a file? I'm asking about standard in the sense of likely to be available on
most unix boxes I visit, so I can count on it (usually) being there, like vi
or cat. I could write one of my own in Perl, but it wouldn't be available
everywhere I needed tend to go.
Is there any standard, or perhaps relatively common, command line hex EDITOR
available on most unix boxes that would let me edit a file (change the bits)
directly in hex?
Finally, is there a really good GUI hex editor for Linux developers? This
one wouldn't be standard, I assume, just a good program that I could perhaps
download as an RPM, now that I'm beginning my exploration of the world of
Linux.
Thanks.

1. Don't know of any reason you would need to create new device files
for a motherboard upgrade. Done this several times and never needed to

2. Could be the kernel version. I believe 2.2.12 had memory leak that
