I understand from your post you're talking about a parallel port zip -
if not, state it clearly.
For the PP zip, first your parallel port must be correctly configured;
then, you must use the correct driver. For the zip100, the module is
called ppa.o. Try:
/sbin/modprobe ppa
Of course, you must be root for this. If it works, you can setup the
module to load automatically at boot - I'm not familiar with either RH
or mdk SysV-style init scripts; in Slackware, I would put the above line
in /etc/rc.d/rc.modules.

I recently benchmarked a K6-3 on a VIA-based EPOX m'board with a
Samsung 4gig ATA-66 capable disk drive using kernel 2.2.13 from
Slackware 7. The system installed & ran with no problems. I patched
the kernel source to include ATA-33, which also ran with no problems.
My "benchmark" was compiling the kernel; ATA-33 decreased the compile
time from 3:47 to 3:40, a whopping 3% improvement. This is in the
same ballpark as a 6% performance increase claimed by someone who
patched a kernel to ATA-66.
I don't consider a kernel compile in 64M of ram a significant disk
benchmark. It does show me that, given how I use computers, ide
vs. ATA-66 vs. scsi makes little difference.

Subject: samba printing
Date: Tue, 09 May 2000 15:14:12 -0600
I am running Mandrake 7.0 with samba-2.0.6-4. I have been
trying to make samba printing work but have NEVER been able
with Mandrake. I have tried setting up the shared printers
via printtool to no avail...all entries were correct and
triple checked. When I try to print a testpage, nothing
happens and all I get is a message to root that the file
could not be printed. Nothing in the logs to explain
further.
I tried setting up the printers via linuxconf but still
fail to print. No error messages. I have checked
/var/spool/lpd entries for the printers (lp, lp0, and lp1)
and see that they are all owned by root and part of root
group. Is this correct? Shouldn't the group be something
else like daemon or something? Are all the entries in the
/var/spool/lpd/lp* directories supposed to be owned by
root and root group?

enter this at the command line prior to connecting to the internet.
echo 1 > /proc/sys/net/ipv4/ip_forward
Then connect and see if it works. If it does then edit the
/etc/sysctl.conf file and change the line:
net.ipv4.ip_forward = 0
to: net.ipv4.ip_forward = 1
By doing this you won't have to enter the "echo 1" line above ever time
you boot the system. If it doesn't fix the problem then unless you
change the sysctl.conf file the echo line will be forgotten the next
time you boot your system.

This is all possible and others are doing it. If you are already using
Netware Clients and ipx on the workstations, then mars-nwe & ipx is a
stable environment for providing the windoze clients with bindery based
authentication to Linux based file & print services.
A question - who will be implementing this and what is their
knowledge/skill level?
If you are paying someone else to plan, install, configure the switch,
it could be done very quickly say 25 hours work for an expert. If you
are learning from scratch (probably as you are asking the questions) you
can expect to spend a significant amount of time learning how to use the
operating system & software, before getting to the stage where you can
achieve what you want - at least 5x the 25 hours.
A suggested option would be to get a machine for the sys/net admin to
tinker with for 50 hours, then pay for and go on a week long training
course. When that is done, pay for a consultant to complete the install
& config and the sys/net admin can then maintain the network easily
using the consultant for 3rd line support, which shouldn't be very
frequently, whilst learning on the job.
This may seem like an expensive option, but in the long term will
probably give the largest return on investment.

But you can add an "auto" option to fstab so that mount will automatically
detect the correct file system type, so users should never need the -t
option.

I am trying to get my modem working. linux (turbolinux) is finding the port

I have tried using

i.e. if I do a setserial /dev/modem it is still set to 2.

Yes - that I knew about already, and overcame. I just wondered if there

You need to install kernel sources. If you are using a RedHat (RPM)
based system you can install kernel-source.rpm .
If you have your GUI running, use "make xconfig".

Linux (and UNIX in general) has a 'standard' layout for various things
(binaries, libraries, config files, etc.). Unlike MS-Windows, Linux
(like UNIX) presents a single *logical* file system tree. Under
Linux/UNIX things *appear* to always be one file system, whether it is
one partition or 256 partitions. One can 'mount' physical file system
(disks / partitions) anywhere that is 'convenient'.
The Linux installer will make a file system tree something like this:
/
/dev
/boot
/bin
/sbin
/lib
/etc
/mnt
/tmp
/var
/var/log
/var/spool
/var/run
/var/tmp (some systems)
/var/lock
/usr
/usr/bin
/usr/sbin
/usr/lib
/usr/man
/usr/share
/usr/tmp
/home
(There is more, but this gives you the *basic* idea.)
It will put in /dev little device files. Lots of them, but all zero
length.
It will put boot files (vmlinux, initrd, etc.) in /boot.
It will put base system utilities (needed in single user mode, before
/usr is mounted) in /bin, the libraries needed in single user mode in
/lib, and the base system daemons and priv. utilities is /sbin.
It will put configuration stuff in /etc.
So far everything would be in /dev/hda2.
Next the installer will put user applications in /usr/bin, non-critical
system utilities in /usr/sbin, their libraries in /usr/lib, man pages in
/usr/man, and shared data in /usr/share. This all will be in /dev/hda6.
It will set things up in /var -- this is where system run time stuff
happens -- mail, news, and print spool, running daemon PIDs in /var/run,
locks in /var/lock (or /var/run/lock), system log files in /var/log,
etc. This is all on /dev/hda7.
Finally, user personal files (and stuff like initial HTTP pages and anon
ftp files) will go into /home (/dev/hda8).
How does the Linux installer know which partition is which? It
doesn't. Early in the install phase you tell the installer where to
mount each partition -- this maps devices (/dev/hda6) to mount points
(/usr). Once everything is mounted, the installer just puts stuff in
the directories where the stuff belongs, as told by the stored file
structure in the packages (rpm/cpio, tar, whatever) used by the
distribution.
On a running Linux (or UNIX) system, *partitions* are not a *visible*
part of the file system tree, unless one uses the df command. One uses
the cd command to move from directory to directory *seamlessly* --
a different *physical* file system (partition/disk) is not selected by
some special syntax or command, like it is in MS-DOS/MS-Windows. If you
never use the df command, you are presently with the *illusion* of one
single file system, even when it is broken up across multiple disks and/or
partitions.

Hmmm...jog your memory. Did the e2fsck program return a lot of messages
