Try 'autofs', there shoud be an RPM file on your CD. Edit the two files
/etc/auto.master and /etc/auto.misc to suit your needs. It should come
with an example, and it is pretty easy. You can automount all sorts of
things. It does not automatically mount it when inserted, but when you
try to access files there (isn't quite the same). It automatically
unmounts it after a delay. When the delay is short, you can open the
drive shortly after the last access.
It is *not* part of the kernel; it's just another useful daemon hanging
around.
There is another tool 'automount', which is also nice, but focuses
on other things.

Hmm, you would need a Linux system on a floppy (or running
diskless on a network) to run the /sbin/lilo installer.
And most Install Disk or Rescue Disk packages don't have lilo.
But you could grab the /sbin/lilo binary from some other
Linux system. You will also have to copy boot.b and chain.b
from there.
So, you would need a partition that lies entirely in cylinders
numbered less than 1024, that is not stackered or compressed
or encrypted or EZ-Drive'd or OnTrack'd. Make a lilo
folder on it. Copy chain.b, boot.b, and lilo there, somehow.
Boot the rescue disk, get a shell, and mount the partition. Say it is
Windows-98 on /dev/hda1 (i.e the "C: drive"). The mount command is
mkdir /c
mount -t vfat /dev/hda1 /c
Now use whatever text editor exists on the rescue floppy to create
a file /c/lilo/lilo.cnf containing
boot = /dev/hda
install = /c/lilo/boot.b
prompt
timeout = 100
other = /dev/hda1
table = /dev/hda
loader = /c/lilo/chain.b
label = win98
(you could prepare this file in advance, but if you did it in a DOS
text editor there would be annoying control-M characters in the file)
and then run the commands
cp /c/lilo/lilo /bin
chmod 755 /bin/lilo
lilo -C /c/lilo/lilo.cnf
and the thing should install LILO on your MBR. Notice that we had
to copy lilo to the ramdisk because we couldn't execute it where it
sat in the MS-DOS file system. This will only work if the borrowed
lilo uses the same libc version as the rescue/install disk.
Your mileage may vary. Void where prohibited. Do not attempt to
install LILO while operating heavy machinery.
BEWARE. I have not tested this procedure. Back up all your important
data. Be sure you can boot your Win-98 from floppy in case we hosed your
setup. Also, I have no idea why anyone would want to use LILO on a
system with no Linux on it. (Hell, why would anyone want to use
a computer with no Linux on it...)

Hi Al,
I downloaded VM-Ware for Linux and have been trying to
install it, without much luck. We got it running at school
with NT Server as the guest OS, pretty slick. So I thought
I'd give it a shot at home, the following is the error I
keep getting:
It starts off as it will procede as normal the gives me
this,
===============================================================================
No exact match for vmmon-up-2.2.9-19mdk
checking working alternatives
No Alternatives found, please build drivers locally
None of the pre-built modules seems to work on this machine
sh: make: command not found
Something is wrong with the system include files on your
machine. The file <linux/version.h> is for a linux system
but you are running a 2.2.9-19mdk kernel. this will not work
for building VM-Ware device drivers; you must have include
files that match the version of your operating system.
==========================================================================================
Any Ideas Greatly Apprieciated.
Thanks

I've been struggling with trying to send PCL commands to my LaserJet 4L

to get them to work from either the commandline of a "text" file. One
person on a maillist sent me a binary that worked, printing a landsape

What I am looking for are concrete detailed examples, KNOWN to work, that

Date: Mon, 02 Aug 1999 02:16:37 GMT
You are basically correct. To get an X server running on your imac, you
may need to buy a commercial package however. (there must be something
for mac)
then you could either just run individual X programs by launching them
thru
telnet (make sure your DISPLAY env variable is set to something like
your.machine.name:0.0 to tell the program to use your imac as the
screen)
OR
you could run xdm which is a little more tricky to set up and then get
graphical logins to your redhat box.
Either way the major hurdle is getting the X server on your mac. There
may be some free/shareware solutions but i'm not too sure.

That would be impossible, because it depends on what you use the
link for as well as how fast it is and what the latency is.
For rough idea of what differences you might find, think in
terms of efficiency and timing for PPP packets. A PPP packet
has 40 bytes of overhead (addressing, etc.), so whatever the mtu
is set to, that amount minus 40 bytes is the actual payload.
For example, if you set the mtu to 128 there will be almost 1/3
of each packet that is overhead and does not contribute to data
transfer. If you do only large ftp transfers, that would cause a serious
increase in the time it takes to transfer each file.
But then again, if you set the size to 1500, which will reduce
the overhead from 40/128 to 40/1500 (31% down to 2.6%) to get
faster ftp transfers, you have a different problem. In this
case any interactive tasks that are using the same link will
always have to wait will huge packets are sent. The bigger the
packets and/or the slower the link or they higher the latency of
the link, the more annoying the waiting time will be for
keyboard response.
Hence mtu depends on the mix of applications using the link,
the speed of the link and the latency of the link.
I tend to do about an equal mix of both file transfers and
interactive applications, so I try to set my mtu as low as
I can and still get reasonable transfer rates. I don't think
a 10-15% rate reduction is too bad (I've seen people who do
data transfers all day get very excited about the last 2% they
can squeeze out!). If I didn't do any file transfers then
an mtu that cuts it down to 50% wouldn't be unreasonable.
Likewise if the wait time is small anyway, such as will be the
case if you have DS-1 (1.544Mb) data rates or higher, then there
is no point in not using a large mtu.
The point is that setting the mtu is a judgment call, and
cannot be objectively determined by a program.

Could you post a little about what tools you use under Linux?
I'm curious as to state of Linux wrt things like emulators,
prom/pld design and programming, pc board layout, logic
simulators, cross-compilers, etc. I used to sell some of this,
and still get occasional inquiries for recommendations - I
wouldn't mind supporting Linux tools if they exist.
Thanks in advance.

I just got the same drive, and have had very similar error
messages. I've only burned audio CDs so far, but they have been
completely usable. What version is your firmware? Mine's 1.4D,
I believe... it's certainly not the newest version (2.0something).
Maybe that solves the problem (for us, anyway)...

I think the Linux kernel disables this by default. If I am wrong I am sure

Howdy all!
I have a friend who is going to do some Web serving for some local
charities. I told him that Linux is the way to go, or would at least be
fun. He's got a Pentium MMX 200 running Win 98, and the plan is to make
it dual boot with some version of Linux. I'm a programmer and I told him
I'd get it set up for him. Of course, I've never done anything with
Linux, and perhaps I suggested Linux cause this is a good way for me to
get some experience.
My first question, of course, is that I'm going to need help picking a
distribution and installing it. It seems that RedHat is the most popular
install, but Slackware is the best suited for beginners. Also,
configuring a PC so it can boot either Win98 or Linux certainly seems
possible, but I can't find just how to do so. Since this is obviously a
hugely common problem, there's bound to be some info on it somewhere
that I simply don't know about.
Also, what I'd really like to know is if there's some Linux Users' Group
or the like in Houston, as then maybe I could just find some kind soul
who could help me along in the beginning here, and I could pay for pizza
and beers. Is there a central directory or anything for Users' Groups?
I guess that's it. I sure hope we end up using Linux, and thanks in
advance to anyone who can help!
