This is hardly going to take more than 5 minutes. He says it goes on
forever! Perhaps he should have a look with "top" to see what is
running.

Oh yea, yeah, now I see I was wrong, of course, yeas, just think of it, the factory
workers will be able to shop on-line while operating their favorite lathe! Kewl, dude.
To
check how their stocks are doing, transact their banking online, make a reservation at
a
favorite restaurant in Seattle, stare at some nekkid broads while them forklifts are
running wild around. Read some unimaginative crap on Salon-dot-com. Productivity will
soar
that's for sure. That's the end of the shop floor as we know it.

You don't. Use leafnode, as I suggested. Inn can also serve out of the
leafnode dirs, but I've not found it to be as convenient as letting
leafnode serve.

Thanks for the example. That's what I needed. I assume this will work
using a script in place of a bash command?

Subject: Procmail default directory
Date: Mon, 16 Apr 2001 02:26:22 +0200
Hi,
I'm currently trying to make a mail-server out of my linux box (SuSe
7.0). It should work with IMAP, so the mails will stay on the server.
I have fetchmail working so far, getting my mails via POP3 from my
provider. Now I found that procmail stores all the mail in
/var/spool/mail, which is on my root disk. I want it to be stored on
another disk, since it can get big I guess. Where do I set the default
folder for procmail? Without compiling procmail from source?;)
And are there perhaps any hints on setting up IMAP? I found the binary
of impad on my system, but some HowTo would really be helpful....
Lars

This is what it says:
If the *time* reserved word precedes a pipeline, the elapsed
as well as user and system time consumed by its execution
are reported when the pipeline terminates
And it defines pipeline as:
Pipelines
A pipeline is a sequence of one or more commands separated
by the character |. The format for a pipeline is:
[time [-p]] [ ! ] command [ | command2 ... ]
So I don't see how it could be misconstrued! You have the trivial case
of a pipeline of one command. So no pipe (vertical bar) symbols.A It's
just. You also don't want the optional negation symbol. I haven0t the
faintest what -p means, but it's optional, so so you just want:
time command
for values of command ranging from echo hi, to make bzImage.

Well, there are a lot of reasons why one might want to do this.
1) rollout of new versions is effortless. Just install the new pages,
scripts, etc.. and it just works the next time they load a page. You can do
this by centralizing the apps in a traditional environment as well, but then
you have to get everyone to exit their processes and reload. This isn't
something you would want to do automatically because users might have a page
up for a specific reason, and killing it on them could be disasterous.
2) You can use very low-end hardware for terminals (win 3.1 boxes even).
3) If you have Macs, PC's, Unix machines, etc.. they can all use the same
app without changing it, and without resorting to Java.
4) You get nice features "for free", such as the ability to open multiple
windows effortlessly and show different information, the ability to use the
"back" button to go back to previous data, etc..
5) You can let your sales staff access the information on the road easily
(and again, you don't have to get them to load new versions of the apps or
force them to download large apps when things are updated, etc..)
Of course many of these things can be done other ways, but HTML just makes a
lot of it easy and simple to implement.

Depends on the kind of factory it is. If it's a PC assembly line, the
terminals aren't in very heavy duty environments. Also, the system is used
by more than just people on the shop floor. It's used by sales staff, order
entry people, RMA people, accounting, HR, inventory, shipping/recieving,
etc...

I believe that typing 'man procmailrc' and hitting the Enter key will
enlighten you. Specifically the section on environment variables, and
in particular the MAILDIR and DEFAULT variables. You might also want
to check 'man procmailex' and /usr/doc/procmail-$VERSION/examples ( if
it was installed on your system, RedHat at least puts the examples
from the procmail distribution in there ) for example recipes.

all the reasons you give describe a thin client arrangement, i.e. a client

Date: Fri, 13 Apr 2001 08:50:15 GMT
Hi,
I have a parallel port ZIP100 (first generation) and after installing my
IDE/ATAPI CD-Writer it didn't show up in 'cdrecord -scanbus' anymore.
Now, for some dark reason (I think turning my parallel port to Normal
and back to ECP/EPP did the trick) it show up in the listing. But, when
I try to mount /dev/scd4 (as this should be the ZIP partition on the
disk) it moans about /dev/scd4 not having correct major or minor number.
Can anybody first tell me what that major/minor numbers are exactly (or
tell me to RTFM and point me to that FM) and what they should be. A
transcript of cdrecord en /dev follows:
root@thorax:/home/bart# cdrecord -scanbus
Cdrecord blabla

/dev/scd4 is the 5th SCSI CD-ROM connected to the system.
/dev/sda4 is the 4th partition on the first SCSI disk connected to the
system.
I think you want /dev/sda4 for using a parport ZIP disk.
