What you want is something called an MRP or ERP. This stands for
"Manufacturing Resource Planning" or "Enterprise Resource Planning". Such
systems track inventory (both raw materials and end product), Bill of
Materials, Work Orders, Etc..
Some of them include Customer account tracking (which cusomter received
which product based on work order, etc.), Order management, RMA (Return
Material Authorization), Accounting, ordering and prediction of raw
materials, etc..
I can't answer your question about whether Linux would work for you, But I
thought you should at least know the terms used for the software you're
looking for.

I have a eps file from my scanner which I'd like to printout as a full
page pic. I thought there was a program which would resize this, but I
can't find anything. I do have psresize, but it only seems to work with
ps, not eps files.
So, what I want is a psresize which will take a eps file and enlarge it
to fit a lettersize sheet.
Thanks.

Yeh, I read about that. Microsoft is pushing to outlaw Linux and other
open source developments. Will this affect exchange/sharing of ideas or
philosophies in software design, or distribution of the binaries?

I haven't read about it, so I don't know MS's stance on the issue, but the
chance of making open source projects basically illegal is infinitely close
to zero.

If you just have 1 dialin modem, and it uses mgetty AutoPPP, you would
specifiy an IP as the 4th field in pap-secrets (see 'man pppd'). Just
make sure you have a name for it in DNS (or /etc/hosts).

All you should have to set in the client is username and password. If you
have DNS you can pass the server IP's as ms-dns pppd options on the
server.

The only protocol you should have checked in DUN is TCP/IP (uncheck IPX,
Netbui and 'Login to network'). You can leave any of the compression
things checked and default route (on client only).

Where is the name of the dialin client? You need names for both ends of
the connection, but the server can use its LAN IP with pppd proxyarp
option for its local IP.
I could be wrong, but I believe that each name should only be listed for 1
IP. You have 'gtech' listed twice. I use 127.0.0.2 for my hostname.

+pap asks the peer (other machine) to authenticate itself and Windows
doesn't do that. The auth and login options handle the pap authentication

pap-secrets needs a 4th field (allowed IP) for dialin (can be *).

I just work with a system now with two scsi controllers and eight
devices now (potentially more later) and I also thought it would
be good to have scsi devices which doesn't move if I remove/add
devices.

Even that doesn't always help. If you have a system where, say,
/dev/hda2 is a FreeBSD partition and /dev/hda3 is an extended one,
then you have a chance to screw up. Once I had such a system, and when
I tried to install a new distro, it formatted a wrong partition
since the install kernel didn't recognize the FreeBSD as a quasi
extended partition so all partitions on /dev/hda3 shifted.
With my kernel, the system handled it as
hda1 hda2 <hda5 hda6> hda3 <hda7 hda8 hda9>
However, with the install kernel, it looked like
hda1 hda2 hda3 <hda5 hda6 hda7>
I tried to format /dev/hda7 and it formatted the last partition instead.

Subject: Recovering BootMagic after RH7.0 Install...
Date: Sun, 25 Feb 2001 04:30:08 -0000
Hello:
Windows Me was installed on my Dell 8100 (P4 1.4, 256M RAM, 2 hds -- 20G
HD for RH).
I had installed partition magic 6.0 to assist with reformating and
partitioning the 20G HD (no problems there). Bootmagic, the lilo of
Partition Magic, was installed and working (even if Windows Me was the
only option).
I installed RH 7.0 (from disks from the Red Hat Linux 7 Server book by
Mohammed j. Kabir--Great book by the way). RH boots to the Red Hat lilo
screen with THREE options: 1. Linux (selectiing this option hangs the
system); 2. Linux up (this gets me to the RH linux os); and 3. dos
(Windows Me).
My question is this. I know I can get Bootmagic to allow booting to
either Windows Me or RH Linux. However, even after I select the "dos"
option in lilo, I do NOT get BootMagic.
I am assuming (but want confirmation :) ) that I can simply run the
Bootmagic reovery option under Windows Me to recover the Bootmagic os
screen and configure it as I wish...
Any comments?
Thanks,
James

For me, changing configuration (baud rate, serial port, etc.) often seems to
have no effect unless it's absolutely the first thing you do when you start
the program. I don't know how many hours of time I wasted because minicom
didn't have the baud rate set to the value it claimed it did. I never got
sending a file to work either -- the end of the file always gets chopped
off.
I also find it infuriating that non-root users can't change configuration
values. Apparently the author of minicom was unaware that the serial port
device files have mode bits, and thus one should leave privilege decisions
up to the OS.
I finally got fed up with minicom's unpredictability and repeatedly finding
that what were reported as bugs in _my_ software were actually bugs in
minicom. I down-loaded and built ckermit. Next time the test group reports
that they've found a bug in my software using a test setup that involves
minicom, I'm going to refuse to look at it until they reproduce the bug
using kermit.
[The minicom user-interface also drives me nuts. I find typing commands to
ckermit takes a fraction of the time that the menu system in minicom takes
-- but that's a matter of personal taste.]

Microsoft is working hard to win the server market, but their reputation
and
the
facts about their stability and security problems still persist.
Personally,
I want both OS's to continue to battle. Otherwise, stasis will ensue.
But, unless Microsoft keeps improving, they will never win the server
battle.
People may buy them, but tire of the endless upgrade cycles, OS churn,
inflexibility, personnel costs, and instability.
>>
A note on the server market, especially the high eng.
One reasaon MS is still struggling there, other than the obvious, is that
it is still basically a Intel based platform and Intel servers still have
serious limitations.
MS really has no one to blame but themselves on this one. Technically,
there's no reason why Win OS's couldn't be ported to more platforms, but
their Eula makes it nightmare legally...and if you do manage get past the
legal issues, what's to keep MS from losing interest halfway thru the
project and bailing out.
Wiht unix like os's (esp. certain open source ones), the only obstacles are
technical one.

Subject: help with bandwidth management
Date: 25 Feb 2001 01:59:36 GMT
Hi Everyone,
Is there any freeware or shareware in Linux that allows me to
control the bandwidth utilization of specific services. Right
now, I am connecting my linux box (running Redhat 6.2 with
kernel 2.4.2) to an SDSL connection (256kps upload/download).
I am running both FTP and telnet services on the same box.
The problem is that everytimes someone is downloading a
large file from my linux box, the ftp server will basically
consume all the bandwith thus making life very miserable for
other users who use interactive applications such as http, mail
and telnet until the ftp session is completed. I would like set
aside a maximum of 192kbps for the ftp server and 56kbps
for telnet server. Can this be done on the linux box?
I know that checkpoint has a software called flood-gate that
does similar thing but I am looking for freeware or shareware.
I am really desparated for a solution. Please help.
Many thanks.
David

Not to be too annoying, but a one-minute Google search finds Linux
versions of Solid State's MPAC and Mapics for Linux. There doesn't
appear to be an Open Source/Free Software solution, but several
respected commercial products sure seem to exist in Linux versions.

Below is my dmesg. I believe that my drive is being recognized as an SCSI
one, and when I mount it I use /dev/scd0 and it works. I believe I have all the
modules loaded:
ringa:~$ /sbin/lsmod

sr_mod 16380 0 (unused)
sg 14872 0 (unused)
scsi_mod 58280 2 [sr_mod sg]

ide-cd 23312 0
....
but when I run cdrecord -scanbus:
ringa:/opt/schily/bin# ./cdrecord -scanbus

I think the SCSI emulation is fine. Maybe there is a module I am missing.
I do have all the devices, I ran both scripts in the CD Writing HOWTO.
Thanks for any info.
