I'm using W2k pro with Mandrake 7.2 in a second partition. The boot loader
is instaled on the MBR and I have no problems.

I thought it was /boot (your boot partition) and not / that needed to be

Easiest way is to capture the above in a script and make it run at boot
time. Check out redhat's booting stuff to see how its done. As far as the
one static IP address; that will be held by your ppp connection. Now for
the windows clients you will want to create a "private network" of sorts for
them. I am anticipating that you have an ethernet card that connets to a
hub that the windows clients also connect to. Go to the linux box and
create a networking configuration for eth0. This can be as simple as
using netcfg to bring up the eth0 connection and then give it a private IP
address like this:
Linux router, gateway - ppp is some external address like 207.xxx.xxx.xxx
(this is your one static IP address). Add the default gateway, dns, etc your
ISP has given you.
Linux router, gateway - eth0 is perhaps 192.168.0.1
Now you will want to ensure as you set the default route that it points to
the external address for the ppp connection on the linux box. Also be sure
you enable IP forwarding as shown above and you have a minimal firewalling
or better in place to protect yourself on the wild and wooly net.
Now boot the windoze clients. Lets say you have 2 of them.
Client 1, 192.168.0.2, netmask 255.255.255.0, default gateway 192.168.0.1
(IP address of the linux box'es eth0 connection)
Client 2, 192.168.0.3, blah blah blah
Now you will want to visit each client system and ping the gateway address
to make sure things work. The 192.* addresses will be transparent to the
outside network, IOW not seen. All that will be seen is the one static IP
address. At home, I have one static dsl IP address. I masquerade several
systems behind it with 192.* addresses.

Neither.
The partitiontable (the one on your HDD) is updated when you tell fdisk to
write it. Other parts of linux don't read the table from HDD themself, but
use the table as you see it in /proc. And that's the one that's not updated
always.

Do as you planned, and after you removed the master, use the root=/dev/hdaXX
append string to boot your linux again.
(If you don't supply it, lilo will try to mount the rootfs on hdbXXX)
Then after you rebooted, rerun /sbin/lilo again, and all will be fine again.

You can use LILO just as well as the NT loader.

Indeed (well actually the kernel image must be), so make a small /boot ,
from cyl. 650 to 651 and assign that /boot
After that you can make / as big as you like.

Yes.
The easiest way is to boot linux from floppy in that case.
There are other options, but don't bother yet.

I run a background process continuously (SETI@home) with a load ave of
1.00 (or sometimes temporarily higher), and never have any problem with
night time security checks, log rotation or processor intensive slocate
(updatedb) tasks run from cron. But SETI@home only takes a fixed 14 MB
of RAM.
7:25am up 48 days, 13:54, 5 users, load average: 1.00, 1.01, 1.00
Perhaps you should take a look at 'man nice' which can run processes at a
lower priority. With SETI@home using a commandline option to run at nice
19, I do not even notice that my box is running 100% because foreground
tasks have a higher (normal) priority.
But I suspect you are either doing too many tasks that entirely consume
your RAM until your box gets too behind in its swap, or if someone wrote
their own binary or script, maybe it has a memory leak or does not
properly flock files it is using.
If you really want to know what swap slowdown is like, try running gnome
or KDE on an 8 MB 386. That box used to run X faster than Win95, but that
was Slackware 2.0 (kernel 1.2.x), and X was much slimmer then (fvwm95 vs.
gnome or KDE now).

Hi,
I upgraded my system to RH7, which installed php4 (i was running php3
before).
The only problem i have is that the install compiled php without mysql.
So now i have to add in my scripts the line <? dl("mysql.so"); ?> so it
would load the mysql functions, and it works.
Can somebody help me change the configuration so that the mysql support
would be automatically loaded when the server starts?

Date: Sat, 10 Feb 2001 08:10:13 +0500
I have an old laptop that I want to put linux on. No sweat, I though, I
just get a mini-linux distro on a floppy, format the drive, set up the
network card, and off I go.
Well, this is one of those "external floppy" laptops - and I've lost the
floppy drive.
So I have a laptop with a functioning 700 MB HD, with win95 installed, a
3COM 589 PCMCIA network card, a hayes pcmcia 56K modem, and no CD ROM and
no floppy.
For the life of me I cannot figure out how to get linux on this thing.
Every install procedure assumes that you have a functioning floppy to boot
the installer. I've heard of ftp installs - but I have not found a HOWTO
on it.
The only thing I can think of is to remove the HDD, stick it in another
machine, install linux, and reinstall it in the laptop.
Any better ideas? This is driving me nuts!

I just bought a Toshiba 2800, 128 MB RAM, 6 GB HD, 1024x768 LCD, real 8MB
AGP video (NOT shared memory) for $1240 - a steal (www.cdw.com). There is an
excellent HOWTO on getting the modem to work, so now I have sound, modem,
network, etc. all built-in.
Yes I also have winME, but who cares at that price. The closest Dell
could come to that price was about $2,200.
There are some good laptop utilites for the toshiba, and tehe 2.2.18
kernel even comes with Toshiba laptop support....

The most reliable way to get the erase character with uncooperative
systems is to set it in the shell that you log into by typing 'stty ' and
then hit your backspace key and enter. Then it will be whatever ^? or ^H
that your system uses. It might also depend upon which shell you use.
Note: Even though RedHat and related Mandrake use different erase, each
seems to recognize the other. FreeBSD also recognizes either.
But Solaris does not. So when I do this in my .login (csh) at my ISP
(the cons25 thing is for logging in from a FreeBSD console):
# Set Terminal Options
# setenv TERM vt100
if ("$TERM" == "") setenv TERM vt100
if ("$TERM" == "unknown") setenv TERM vt100
if ("$TERM" == "cons25") setenv TERM vt100
stty erase '^H' kill '^U' intr '^C' eof '^D' quit '^\'
stty echoe -istrip tab3
# added following line when switching from RedHat to Mandrake
if ("$TERM" == "xterm") stty erase '^?'
if ("$TERM" == "linux") then
setenv TERM vt100
stty erase '^?'
endif
Putty (Windows ssh client) can store an erase setting for each connection.
