There are no clear guidelines for swap. Most people go with a
single swap partition. I do not know of any benefit of using two
or more. The size of the swap should be based on your amount or
memory, the software you will be running, and how hard you are
going to be driving that machine. A single swap partition of
128 Mb is ample for most people, most of the time. If you were
a home user and had something like 1 Gb of memory, you would
probably not even need swap. Swap is there to as a safety net
for when the system is running low on memory. With my distro
I can limit the amount of memory that users are allowed with
the /etc/security/limits.conf file.

Maybe your house is not grounded well. If the house is grounded
poorly, then your attempts to ground your computer are useless.
That is worth checking into. Also, if the computer's power
supply is bad, then the computer might be injecting a signal
back into your home's wiring. You might only notice the effects
on radio equipment (like TVs). Since computers generate
frequencies in the MHz range, they are effectively broadcasting
on the frequencies that television stations do. You should
use a surge supressor on the computer that has noise-filters
(RF filters). You should have one of these anyway since they
are vastly superior to the surge supressors that have only MOVs.
(That is also a hint to everyone reading this). Surge
supressors with RF filters will block signal interference in
both directions. One word of warning however. THIS IS
IMPORTANT. If you want to use a back-up power supply with this
type of surge suppressor, make certain that the surge
suppressor is plugged into the outlet. Do NOT plug this type
of surge suppressor into a back-up power supply; because these
surge supressors have a tendency to amplify changes in current
and reflect them back to their source... a fried UPS.
Electronics can be neat.

The following questions relate to my small network consisting of Mandrake 7
as a server / internet gateway and a few Win 9x boxes as clients.
In my /var/log/samba/log.smb I have many of the following entries
Denied connection aaa.bbb.ccc.ddd
These are not part of my local network so I assume they come the internet.
Should I worry?
Also in log.smb I have many instances of the folowing message when a win9X
box tries to log in ( although the login works and the Win box accesses the
correct shares.
lib/utils_sock.c:client_name (0997)
gethostbyaddr failed for 192.168.0.100
I am not sure what to do with this one, so please give me a hand.

Subject: samba and password usage
Date: 15 May 2001 21:34:24 +0200
I have a small network consisting of a Mandrake 7 server and a few Win9x
clients.
When I first set this up for test purposes, I allocated a username and
password at the server and then as root did smbpasswd -a <username>
<password>.
This worked fine but I now need to go live and I need to allow users to
select their own passwords and also to force them to change these passwords
every so often.
Is it possible to do this by having the server prompt for a new password
when they log in from a Win9x box? If not what do you suggest?
Thanks

Subject: file permissions - still struggling
Date: 15 May 2001 21:36:21 +0200
I am running up a small office network - Mandrake 7.0 as the server and e
few Win9X boxes as clients. My requirement is that all users have file
creation, deletion, and modification rights to files within
/home/public/"project_name"/"various_subdirectories" but can not modify or
delete the actual "directories". Any file created by a user should be
automatically accessible to all users in that group but should preserve the
creator's/modifier's user name.
This rule should aply to non public directories as well. I have tried
"force create mode = 0770" and force directory mode = 0765 in the [shares]
section of smb.conf but I am missing the magic combination somehow.
I still have not found a simple description of the suid, guid and "sticky
bit" functions and when to use them. Is there a howto or something similar
Thanks

Show off!
Seriously, I hope you realize that you probably lost about 99%
of your readers in that posting. I have studied (general)
electronics, and you even lost me at several places.
Nevertheless.. It was interesting and worth saving for future
reference.
By the way... Your last point (quoted above) is a very good one.
Having the entire input shielded by the "common" ground is
excellent, as is in the case of coax cabling.

As root, run 'ipconfig'. This will list all interface addresses and properties.
If you only want to see one interface, then use 'ipconfig devicename' - for
example, 'ifconfig eth0'.
You can also use 'ipconfig' to assign an address to an interface, as in
'ipconfig eth0 192.168.1.1'.

Looks as if you would miss nothing, check if your script is executed on
run level change. I don't know about linuxconf, but from what I have
heard
about it, it's like yast, that comes with SuSE, it's working quite nice,
but you don't really need it, if you get used to how Linux works...:-)

That often means that your kernel is too big. Try to put some more in

First download 2.4.4 from ftp.kernel.org. 2.4.2 had some serious bugs.
Then do mostly like in the 'old 2.2 days' - but the kernel has become

Thats just the hardware I currently have, though I plan to buy another LAN
card for the windows box, probably the same one as in the linux box as I
have experience getting it to work in either os. Also, I believe the modem
is HCF, so I am probably screwed. The modem currently in the windows box
is essentially a ghost: it came preloaded in a compaq desktop purchased
recently, has no driver support anywhere and is listed as a generic modem
in all windows config programs. That too is an HCF modem.

Hi,
I've got 2 3c509s in a my Linux box (Mandrake 8). One is an ISA card, and
one is built on the Motherboard. Anyway, they are being setup with one as
eth0 and the other as eth1 (obviously). What I want to do is flip that
assignment (long story having to do with cable provider and scripts I've
already written). I want mac 00:10:4b:ce:11:55 to be eth0 and
00:c0:4f:c4:33:37 to be eth1. Here is the current output from ifconfig -a:

I believe that the IRQs and IOs are being setup by PNP, especially since
I've tried the 3c5x9setup executable, changed the IRQ and IO, and they are
effectively ignored.
I've followed the Ethernet-HOWTO regarding eth0/eth1 assignment and setup
the /etc/modules.conf as follows:
alias eth0 3c509
alias eth1 3c509
options 3c509 io=0x230,io=0x220
But I get the following error output after running modprobe:
