I use commands like the following:
dump 0Buf 20480000 /dev/nst0 /home
This is a level 0 dump of the /home file system. the B goes with the
20480000 to indicate a 20meg tape. I believe many tape drives will
properly signal end-of-tape and I think dump will honor the signal in
which case you just need to be sure the number you use is bigger than
the actual tape capacity. I've never really verified this since I never
fill up a tape. Anyway, the above works for me -- I am never asked to
change tapes.
I like the way dump/restore works with only one exception -- it can't
dump my Windows partitions (which I still need to dual boot to once a
week to enter Quicken data). I have a slightly elaborate script file
that runs from crontab to do daily backups at 2:00am. The script uses
"restore tvf" to create a table of contents file for each dump. When I
need to recover something, a simple grep in the directory with these
files quickly tells me which dumps on which tapes contain any given
file.
Another nice thing about dump/restore is that they are tiny little
programs so can be loaded from floppy in an emergency.

Chat scripts usually live in /etc/ppp -- and the exact file name is
specified as an option to the pppd command.
The trick in getting a ppp connection is to work through the various
components in sequence: first get the modem to work, then make a
connection using minicom, and finally put the scripts together. (I wasn't
sure from your posting if you'd ever got your modem to work by itself.)

How does `Linux' push KDE or GNOME? Hint: Linux doesn't. Maybe the
distributors do. Maybe the community does. Linux doesn't.

I should probably go back and check, but that isn't my understanding.
I believe Kernighan has written that ``unix'' was a weak pun, related
to Multix (Multics? this was all way before my time...) But his point,
as I recall it, was that unix had one design goal rather than many,
not that it was designed for one user rather than many. If memory
serves, he also said that this one goal was to produce a decent,
multi-user operating system. I am a bit more sure (although not
completely certain) that the use of dummy accounts for various
processes came after AT&T version 6 (the first general release
version of unix.)

The original poster was not clear, at least to me, on what he was
trying to accomplish.
I thought Exceed was an X Window server for MS Windows. It would
come in to play if you had a Linux machine and a MS Windows machine
networked together and you wanted to display an X Window application
on the MS Windows desktop.
I guess I interpreted it to read that he had one machine with both
MS Windows and Linux on it anf that he wanted to read the Linux
partition from MS Windows.
There are a couple of programs that will allow you to do this. One
program is called fsdext2. The file name that I downloaded was
named 016.zip. The last web address I had was:
http://www.globalxs.nl/home/p/pvs
There was another one called lread I believe. I don't have a URL handy.
Another way to accomplish the same thing is to mount the MS Windows
partition from within Linux and just copy the bookmarks.html from
the MS Windows side to the Linux side or vice versa.
You could also use one of the several utilities available on
the MS Windows side and just combine the two bookmark files
and then weed out the duplicates.

Subject: Cheapbytes RH 6.0 upgrade probs
Date: 11 May 1999 19:45:09 GMT
I just got the Cheapbytes Redhat 6.0 CDROM and eagerly sat down to upgrade
from 5.2 (also a Cheapbytes upgrade from Redhat 5.0).
I won't bore you with the problems I had creating a boot disk with RAWRITE.
(The solution involved OS/2, to give you an idea). But, when I booted and
told it I wanted to upgrade, I got into a weird loop, to wit:
1) "Do you have any SCSI Adaptors?" -- I select no. The installer scans the
hard drive, and then
2) "Do you hav any SCSI Adaptors?" again -- I select no -- again.
3) "Mount failed: Device or Resource busy" I then must hit return eight (8)
times to get to . . .
4) "What partition holds root partition?" I select the appropriate partition
5) "Mount failed, Device or Resource busy" I hit OK
6) "Could not mount device."
I can go back and repeat the process, but got tired of that pretty quickly.
I tried warm reboot, cold reboot, expert mode, regular mode. I'm stumped.
I DO NOT have any SCSI devices, BTW.
HARDWARE:
IDE HD 6 Gigs
Mitsumi ATAPI IDE CDROM
AMD K6 200
96 Megs of RAM
So, anyone have a clue for me? Better yet, am I going to go though a lot of
BS to get this running only to learn it screws up something, anyway?
Thanks.

Well, no. I'm typing on a unix box. It is in my apartment and there
is a lock on my door. I connect to the rest of the world using
tip and a modem, and this unix machine is not set up to pick up the
phone is someone dials my number. That means I have exactly the
sort of physical and network security you describe. If I wanted
better network connections, I would use ppp and disable all outside
connections (e.g. use tcp wrappers, and put ``deny ALL'' in the
appropriate file) to produce the same level of security.

I have an external SCSI Zip drive:
I have a pure SCSI system:
3 internal SCSI hard drives
External SCSI CD-ROM
External SCSI tape drive
External SCSI Zip drive.
*Everything* works just fine. I'm running RedHat 5.2 (kernel
2.0.36). I was running Slackware 3.0 (kernel 1.2.13). Under the 1.2.13
kernel Zip disk mounts would 'hang' for a bit (but would work) -- this
is probably something to do with how the 1.2.13 kernel did certain
things like interrupts and scheduling. Does not happen with the 2.0.36
kernel.
I have a 486Dx66 with an Adaptec 1542CF controller (ISA
multi-tasking DMA SCSI-2 (50pin (8-bit) internal/external).
The Zip drive is at the end of the external chain and is the
external terminator. I have noticed that the whole system goes nuts
when I manage to (unintentionally!) power down the zip drive (loss of
termination). This is more a matter of a bad desk 'design' (messy,
loose little zip drive -- easy to knock about, etc.).
Some questions:
What sort of SCSI controller are you using. Which driver? Which
kernel version?
Is the termination enabled or disabled on the Zip drive? Is it
the last/only thing on the external SCSI bus?
Is your SCSI controller a wide controller? With an 68-pin external
connector? If so, do you have a proper adapter that terminates the upper
bits? How is the controller board's termination configured? Are you using
an AHA-2940W with *both* internal busses (68+50) in use? If so, you can't
use the external bus reliably (yes, it will work, but sometimes it won't and
it is NOT a recommended practice).

Well,
I bought the Redhat 5.2 version a few months ago. After installing it
the first time, I found the interface to be a little intimidating (both
command line and X).
I guess one of my biggest problems is the lack of support for commands,
kind of like trying to figure out DOS commands. Does anyone know where I
can find a comprehensive listing of commands, and their variables?
I have tried to find the contents of my hard drive but everytime I do a
ls in a directory, if the list is more than a page, it goes by so fast
that I reaaly have no idea what is in the directory. Any ideas?
Thanks for the posts that all have made in the past, many have been

In general you send mail to [EMAIL PROTECTED]
So your sendmail (?) thinks that linux.org is the host it
should send the mail, but this doesn't exist.
You have to tell your sendmail that it should deliver the
mail for linux.org locally. I have an entry
Cw localhost cube.net
in /etc/sendmail.cf
In my SuSE Distribution this is done automatically
when I set SENDMAIL_LOCALHOST="localhost cube.net"
in /etc/rc.config. (I don't know whats the equivalent in ReadHat)
You can get a similar result when you change your
/etc/mail/mailertable
and run the configuration for sendmail.
Hope this helps

Actually, machines are much more often shared at home than at work.
Most families don't have a computer for every person. And what of the
neighbor kids coming over and playing? Or guests that want to check

Microsoft won't be writing applications for Linux certainly not in the
next year, and unlikely in the next five. Linux is evil incarnate as
far as they are concerned, and porting applications to it would be
violating their FUD rules.
As for anyone else, you do know that there's a kernel patch to break the
PSN, don't you?
The portion responsible for that is actually quite small, being really
only 4 lines of assembly:
movl $0x119, %ecx
rdmsr
orl $0x00200000,%eax
wrmsr
See http://www.uwsg.indiana.edu/hypermail/linux/kernel/9903.0/0269.html
if you want a copy.
Because rdmsr and wrmsr are priveleged instructions, a userland
application can't undo this setting (and, in fact, will generate an
exception if they try).
A simple patch and no userland program would have access to the PSN.
(Would have been really slick if the CPUID instruction were trappable:
then you could forge them and applications would have no idea you were
doing it. Of course, things like vmware or bochs could do that now.)

Indeed, WebTV monitors and reports much more than that. It includes
what commercials you found interesting enough to "click through", and as
Microsoft gets more into 'content' (you think they're buying into
Comcast and being AT&T's pal for grins?) it will become even more of a
concern.
Microsoft has already stated that they are collecting this information
and plan on using it to "enhance" your experiences. Bill-speak for "get
the KY ready."
This isn't a "well, someday, someone may use this to track...", Bill is
using WebTV boxes right now to do it. Wait'll he convinces your local
cable company that they need the new WinCE based boxes. And if your
cable company is one that Microsoft has "invested" in, be very afraid.
Big Brother has greasy hair and glasses.
> This is called invasion of privacy or something.
Nope, it's not. It's just a number which you can trivially supress on a
modern OS. On Linux, you can trust that it's suppressed: on Windows,
well, you'll have to trust Microsoft, but that's already the case for MS
users. (And their trust is highly misplaced.)

This isn't correct. UNIX was intented to be a timeshared operating system
from the earliest days, and the name UNIX was a pun on the name Multics.

and follow any number of links. Of particular note:

This is a document titled "The Evolution of the Unix Time-sharing System"
by Dennis Ritchie himself. From this text you will find the quote:
Processes (independently executing entities) existed very early
in PDP-7 Unix. There were in fact precisely two of them, one for
each of the two terminals attached to the machine.
Its clear from that and the text that followed that the early PDP-7
versions of the system could support multiple users. Other texts off
his home page also refer to the PDP-7 version as a timeshare system
and talk about how it evolved. Its definitely worth reading through..
