I assume that means /dev/hdc5 is mounted on /home, right? And
that /dev/hdc2 is the root partition...

cp -a /home/* /newhome
will do that nicely for you.
Up to this point you could be doing this as root while in
multiuser mode, but before you can do the next step all
normal users must be logged out and no processes that will
use anything (such as shell history files or whatever) in
the /home directory must be disabled. You might well be
able to just log all normal users out and proceed. But
if any normal users have cron jobs, or if the machine allows
user to access it via a network you'll want to go to single
user mode to finish up the rest.

No need to reboot. If you don't have other users and have
done this while in multiuser mode, you can now resume normal
operations. If you went to single user you can now go back
to multiuser.
You can of course go ahead and reboot, just to make sure that
when it does reboot you got /etc/fstab right and the system will
come up properly.

Exactly.
To demonstrate:
jbuchana@zaphod$ ls -li

2015294 -rw-r--r-- 1 jbuchana jbuchana 21 Feb 2 18:53 foo
jbuchana@zaphod$ ln foo bar

2015294 -rw-r--r-- 2 jbuchana jbuchana 21 Feb 2 18:53 foo
[... edit foo with emacs ...]
jbuchana@zaphod$ ls -li
total 12
2015294 -rw-r--r-- 2 jbuchana jbuchana 21 Feb 2 18:53 bar
2015486 -rw-r--r-- 1 jbuchana jbuchana 25 Feb 2 18:53 foo
2015294 -rw-r--r-- 2 jbuchana jbuchana 21 Feb 2 18:53 foo~
jbuchana@zaphod$
The -i switch to ls displays the inode number, the third column shows
how many links exist for the file.

I have a SparcStation 10 on which I would like to install Linux. It is
aclean system with no OS and a 1Gig HD.
I've tried in vain here in Toronto to locate a copy of Linux for Sparc that
I could use. These things are either nonexistent or unavailable here. I have
Linux RedHat 5.4 (Manhatten) and Open Linux 2.3 (Caldera). Both of these
appear to be i-3/486 packages.
Can anyone please tell me how to get either one of my above editions loaded
into a Sparc OR can they help me with locating one of these mysterious Linux
for Sparc varieties?

No it will not. gnoise buffers do not trasfer from one session to the

You could use sox to write a raw files, then cat then together through
sox asgain to get one long .wav
sox file1.wav -t .sw -r 44100 file1.raw
sox file2.wav -t .sw -r 44100 file2.raw
cat file1.raw file2.raw|sox -t .sw -r 44100 - file3.wav
should give you a single .wav file containing both of the other two
files, which you can edit with gnoise (although gnoise with more than
about 15 min of file can get very slow.)
....

a .wav file contains the length of the file in the header. Also the
second files header would get messed up with the music.

I have the same problem. The CTRL+ALT+PLUS/MINUS does not work.
I am using the "OpenLinux In 24 Hours" book and CD.
If you look in the index under Screen/Resolution, I think its on page
147, it mentions the problem of a screen that is too big. It says that
if you add a pound sign (#) to the line on the previous page the screen
size default will be shut off.
The is not possible when you cannot navigate around a 2 acre image on a
15" screen in order to access variou functions, let alone learn the most
basic proceedures.
If you do not have this version of the program or the book I will be
happy to send details. If you DO have this version please feel free to
HELP ME!!!!!!!!!!!!!!!!!!!

Hi,
I just installed a new Linux system where users will connect to it using
telnet. On this server I installer a Digi port server (16 ports RS-232).
These 16 ports are connected to another Unix system that is maintained by
another company. I have no access whatsover to administrate this system. I
would like to have my users to connect directly through a telnet session to
one of the ports on my port server. For example how can I redirect input and
output from /dev/pts/2 to /dev/ttyd0.
Thanks for your time

There has been a rather primitive set of programs out for awhile,
one is called 'stream'. I've used it and you have to pass arguments
giving a start and stop time for video capture (using bttv chip driver,
I suppose the Hauppage has a bttv video chipset doesn't it?), then a
program called mpeg2encode to convert the output of stream to mpeg2
which can be played with, for instance mtv or that player from loki (GTV?).
Only thing is, I never got sound to work. The encantations are as shown
in this snippet from the output of a history command.
615 stream -start 19:40:00 -end 19:40:05 200 180 audio1 video1
617 mpeg2encode str2ppm.par out.m2v
618 mtv out.m2v
I got these programs a long time ago, so probably better to do a fresh
search than me trying to dig out where I found them. As I recall I got
source and had to do a bit of tweaking to get them to compile.

"change the slave"? Um, without special mounting hardware, it's
*UNWISE* to unplug an IDE device from its ribbon cable when it's powered
on. The IDE bus was never designed to allow for hot-swapping of
peripherals. SCSI was, so it's reasonably easy with SCSI.
If you have your Linux root partition on a removable IDE device, you
cannot remove that device while Linux is running. If you have a
removable device on /dev/hdb and your Linux / is on /dev/hda, you should
be able to umount every filesystem on /dev/hdb and swap devices,
provided your removable IDE kit is working properly. There is something
that will re-scan the partition table on any IDE disk that doesn't
contain / , but I forget what exactly it is. Look in the fdisk source?
