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.

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
...well, looks like I've got a device, but no media <g>.

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.

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.

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).

Depends totally on what card. An el cheapo ne-2000 clone will usually be
recognized, but there is a whole host of others out there. Try to find out
what chipset sits on the thing and look it up in the linux hardware
support lists.

You will need to use the initrd image file from your boot floppy.
No matter which loader you are using you need to load the kernel
image AND the initrd image. The initrd image contains the SCSI
driver module and the programs to load it into memory.

Everybod can already run pppd; the pppd does, however, need to be suid

Date: Wed, 28 Jun 2000 08:05:03 GMT
I'm writing a program that needs to be able to give a file to someone
else without being root. System V Unix allows the owner of a file to
chown it to someone else, but Linux doesn't.
There's a variable _POSIX_CHOWN_RESTRICTED which is supposed to control
this behavior, but I can't figure out how to manipulate it. By default,
it's declared as "1". I thought I should be able to do
#define _POSIX_CHOWN_RESTRICTED -1
to turn off this restriction, but it didn't help.
Ideas?

It is not absolutely necessary; but it would be foolish to do
without swap except under some set of very special circumstances
(and you know extactly what you are doing and why). Swap space
on disk is perhaps best put into a separate partition (recommended),
but a file can also be used (handy for temporary needs or testing).
Virtual memory contributes to the reliability of an operating
system, which is the main reason you want more virtual memory.
Cost is the reason to use swap instead of adding more physical
RAM. You should consider your pocket book when purchasing RAM
(buy as much as you can afford, because Linux _will_ make good
use of it as buffers and for disk caching to allow your system
to run faster). But you should then engage in a bit of fantacy
to select how much swap space to allocated. Imagine the worst
case possible use of memory, and have enough swap space to make
sure more than that amount of virtual memory is available.
(Keep in mind just how cheap 500 Mb of disk space is today too.)

That means you can have a MicroSoft OS available also (and boot either
that or Linux), and when you have Linux booted you will be able to
read and write to the MS hard disk partitions and floppy disks.
MS file systems are not suitable for use with unix files.
