If you're using shadow passwords then this is a non issue. Most
modern
distro's use shadow passwords, which do not allow any user to read
the
file.

Isn't there an "after" and "before" directive one can use in
modules.conf
(I am completely new to Unix, so am not sure of the name)? You may
want to
force one of the drivers to wait until the other driver has installed
by
using that.

Dear All,
I have a linux server and the web server is apache.
There is a form for the users to submit and get some information
and say, action='/cgi-bin/showdata.cgi'.
But sometimes the showdata.cgi will not terminate and consumed
a lot of resources. How can I write a script to monitor this
showdata.cgi
such that if it has been running for a long time, just kill that
process.
Could you give me some idea or sample code about this ? Shall I use
cron job ?
How can I know that how long has that process been running ?
Thank you very much.

Repost your specific hardware, including both tape and SCSI adapter
if
any, commands and error messages. Idiot question: do you have a
SCSI
kernel driver loaded? Post output of "lsmod".
One of the following should report something useful (run as root):
# mt status
# mt status -f /dev/tape
# mt status -f /dev/nst0
# mt status -f /dev/st0
Typical output:
$ mt status
mt: /dev/tape: No medium found

Subject: linux swap partition?
Date: Wed, 28 Jun 2000 09:46:30 GMT
From: "Keith" <[EMAIL PROTECTED]>
Hi, I'm thinking of installing linux and I had a question about the
linux
swap partition. Is it absolutely necessary to have a 2nd linux
partition on
your hard drive just for virtual memory. I have 128MB of RAM in my
PC--what
would happen if I installed linux without this swap partition. If it
matters
any, I've pretty much narrowed down my linux choices to either
CorelLinux or
Mandrake (suggestions?). BTW, I can only install linux using that
"linux
ext2 file format," right? I think I read somewhere that linux can
recognize
the FAT or FAT32 file format--is this true?--Does this mean that I
can also
install linux to a partition using FAT32? Help would be appreciated.
Thanks.

Hi
AKAIK it should work. I think the pnp bit refers to the fact that it
can
identify itself to Windows when queried - the only thing you need to
worry about is if it is a 'winmodem'. Being external it shouldn't be.
One thing to try is to make it a condition of sale that it works with
Linux - sometimes the sales droid will understand - the trick is to
get
the same person if things go wrong. We did this with some Family
Tree
software - we had a requirement that it cope with brother/sister from
one family marrying sister/brother from another (it is not incest!!).
This tripped up several of the cheap programs quite nicely.
FWIW I use a cheap USR Sportster external with Linux and set the
machine
up with an aged 14.4k Zoom before transferring the Sportster from a
windows machine.

RedHat users install Debian, then run
$ apt-get install xemacs pine
Debian users skip the installation process <g>.
If you don't care to walk on over to the side of the white hats quite
yet,
vendors tend to have download packages on their websites, or mirrors.
ftp://ftp.varesearch.com/pub/mirrors is a good start.
Freshmeat (http://www.freshmeat.net/) is another good general index.

What specific settings do you want to change?
What distribution of Linux are you running?
You can always edit the /etc/X11/XF86Config file manually, toward the
bottom of it you should have some lines which look like those below.
You can append other resolution settings (provided you've got the
modelines for them) such as 640x480, 800x600, 1024x768, 1280x1024,
etc.
Better yet, you can run a utility (XF86Setup is my preferred tool)
which
lets you configure X. You may have to install this as it's not
standard
with most RedHat and RPM-based Linuxes.

KDE is QT based, proprietory/commercial.

I have a server with 512MB of memory and still have a (small) swap
partition.
The mere existence of a swap file/partition will make things run
faster (the
technical explanation can be left to others). This partition does
not need to
be a primary partition.
You can use FAT (or maybe even FAT32) for your Linux partition - this
is the
'umsdos' stuff, but why should you want to? If you have a partition
dedicated
to Linux then it makes sense for it to be EXT2.

This is not true. Shadow passwords remove the requirement that the
encrypted password be in /etc/passwd. Users *MUST* have read access
to
/etc/passwd (yes that does include being able to copy it) otherwise
all
sorts of things will break - like being able to change password for
yourself or su to another user. Also you won't be able to login, as
the
default shell for a user is obtained from /etc/passwd - it could have
a
default I suppose - I have never tried it.
The encrypted passwords go in /etc/shadow which is only readable by
root.

Depends totally on what card. An el cheapo ne-2000 clone will usually

find out
what chipset sits on the thing and look it up in the linux hardware

First of all, we're not talking about file formats here, but about
filesystems. There are numerous filesystems supported by Linux. You
can
also easily boot from a DOS partition, but if you have a dedicated
linux
partition anyway, ext2 is really the way to go. First of all because
it is
faster then umsdos and second because when your windows machine it is
effected with a virus, it's much more likely that it will take a
umsdos
partition with it then a ext2 partition, because windows doesn't even
see
ext2 partitions.
Then the swap part. It doesn't really matter how much memory you
have, you
still need swap space. This is because linux will stuff all the
memory
that you're not using at the moment with buffered versions of things
on
your disk, so that you don't have to access your disk so often. This
greatly speeds up operation. If your memory is full (and with an
uptime of
a day or so, this is going to happen) and you start a new big app,
your
harddisk suddenly has to do a lot of stuff and so does your memory.
Stuff
needs to be put into your memory and stuff needs to get out of there.
It
would seem that it would be smartest to dump the buffers. The problem
is
that some of the buffer might be modified. If they have, they have to
be
safed to disk. This is a lot of work that has to be done at once. I
once
forgot to set up a swap partition. (In fact I told linux the wrong
partition, but the error swooshed by so fast during bootup that I
didn't
notice). This has the effect that if I started X for instance. It
would
crash immidiately, but when I started it again it would work. When I
installed the swap partition correctly, everything was okay. Now the
kernel can simply swap stuff out without looking if it has to be
synced to
disk. It will still treat everything is if it were memory.
With you amount of memory, I would say that a 100 megs of swap would
be an
overkill. The rule of thumb seems to be that you need twice as much
swap
as physical memory, but that's from the days where we had 8 megs
memory. Nowadays, in my opinion, you need a buffer about the size of
the
largest app you'll be wanting to sqeeuze in. I have 96 megs physical
and
100 megs swap. The swap partition remains largely unused (few megs
used).

Everybod can already run pppd; the pppd does, however, need to be
suid
root to work if invoked from a non-root user.
BTW, don't give write access to system programs to anyone, except
root.

I have tried that, and at least 10 successions of 8193, such as
16385,etc,etc, all to no avail...I reread the posts concerning this
problem
and did check my partition table using fdisk :p and it shows my hda7
being a
valid linux native, starting at 3190, ending 3381.
e2fsck -f -b 1 /dev/hda7
Try this - It worked for me when 8193 didn't
cheers
