http://www.toms.net/rb/ is the most useful set of tools in the general
case. However, it does *NOT* have reiserfs support at the moment;
there's only so much you can fit on a 1.7M floppy. Bug Tom? :-)
http://linuxdoc.org/HOWTO/Bootdisk-HOWTO.html is a good place for
general information. If you want to get everything you're likely to
need, you will need 2 disks: One boot, and one 1.7M root containing the
gzipped RAMdisk. Building your own root/boot is a bit like carving a
miniature walrus out of ivory using only a chainsaw.

A root/boot must contain the kernel, a shell, a bunch of device files,
and a surprising number of small programs and files. "sash" and/or
"busybox" may prove useful. Also check the Linuxcare Bootable Rescue
System, http://open-projects.linuxcare.com/BBC/ , if you have a CD-R(W)
handy. Not only is it a rescue system, you can install Debian with
it....

DING! Give this man a see-gar! If evil idiots can physically access
your machine, that machine is not secure. You can set a BIOS password
and make the machine only boot from the hard disk, then lock the case
with a good padlock and chain the machine to something large and heavy.
University computer labs often do this.

I see no reason why kill -9 1747, run by root, would not terminate
that process. Since I assume you have tried that, I am as mystified as
you are.

I hope I did not confuse you by typing mt in upper case. I just wanted
it to stand out a little more. I would have used bold, but html
posting on this newsgroup is deprecated. In any case, if you run a Red
Hat based system, it is in:
valinux:jdbeyer[~]$ rpm -qf /bin/mt
mt-st-0.5b-7
valinux:jdbeyer[~]$
There is a manual page for it. man mt
In my case, the process does not hog the CPU; it just gets into state
D and never progresses, never unlocks the file, etc. I must reboot to
regain control of the tape drive. Since it also happens with hard
drives on a different controller when I run rpm sometimes, I have
reduced my belief that it is a tape drive (or its SCSI controller)
problem. I have run lots of memory tests, including several hours of
memtest86, I suspect memory errors less and less. The memory is 100MHz
ECC SDRAM.

It depends on what the O.P. meant. You can, if root, certainly run
/usr/sbin/sendmail -q
and try right away to process the stuff remaining in the queue. If the
stuff has already been sent, of course, there is no need to do it
again, and it will no longer be in /var/spool/mqueue. man sendmail
should help with this if you have no access to the Bat Book.

I am trying to install SuSE 7.0 on my machine that has Windows 98 on it. I
have set aside a partition for SuSE. No matter if I do the text or

Probably, but if you value your data and sanity, mount it READ-ONLY.
Also note that 2K made some (undocumented) changes to the way NTFS is
handled at the low level. Search the Linux NGs using
http://groups.google.com/ for "NTFS" and see what the community has to
say.

I would not recommend RedHat 7.0 to anyone, based on the buzz from
newsgroups and my own experience. 6.2 would be OK, but I really don't
like the "user private groups" thing RedHat does. I'd say SuSE 7.1 or
Mandrake 7.2. If you have the drive space, try FreeBSD too! It looks
realtively neat, and I'd have installed it months ago were it not for
this @#$%ing 56K dialup making it difficult to grab the ISO.

Can anyone help me to get Mandrake 7.2 to recognize this card?
Is there a way in Linux to "generate" a device: ie, supply the IRQ, i/o

support it?

Subject: File Transfer by Null Modem Cord HOWTO
Date: 13 Apr 2001 01:53:17 GMT
For those looking for cheap easy connectivity between your Linux laptop and a
non-Linux desktop, a null modem cable is hard to beat.
First step: Make sure your non-Linux computer has a terminal programme that
can transfer files and a serial port.
Second step: Make sure the Linux box has mgetty installed and a free serial
port.
Third step: Buy the null modem cord and attach to both computers in the
obvious way.
Fourth step: Fire up the two boxes, and on the Linux box, login as root with
any old virtual terminal and type in "mgetty -s 115200 -r /dev/ttyS0" (for COM1
/dev/ttyS1 for COM2, etc.) On the other box, fire up a terminal programme and
use it to connect and login. I use VT100 emulation for this.
Fifth step: Enjoy!
If you have a laptop and havn't found out which networking cards to use with
it, this method can be used in a pinch for cheap file transfer. It'll be slow
for big tarballs, however.
With one of them BBS type serial port cards with the octapus cords, you can
have a terminal server desktop serving a bunch of laptops in an office. Even
better is to set up PPP with Slurp for Windows clients.
CAUTION: While the command line mgetty bit works, it works for _one_ login per
running of the command. That means you need some mechanism of looping it so
when a logout occurs, it's rerun automagically for the next person to login
with. You get to make a daemon.
Many people accomplish the above with agetty but that has the problem of
auto-respawning causing stderr messages showing up on the console. Since I
don't know how to stop the respawning, I prefer the mgetty method. The man
page for mgetty is straightforward for command line arguments to run it to
transfer files.
Besides laptop file transfers, it can be used to transfer files between all
the other OSes, so long as they have a term proggie and support a null modem
cord. Config Slurp, and you have the null modem PPP.

You received solutions using awk, and here is one using sed:
sed '/ERROR/bo;/Display/!d;:o;N' data
The N collects that second line. It is easy to add an ^ anchor in the
regex if desired, e.g., /^Display/.
Some seds require that the above be broken up into more than one argument,
so bear that in mind should you get unaccountable error messages. One sed
even demanded a space before the label, i.e., .../Display/!d; :o;N' data
