This is an excellent, well-formed, and reasonable response. I am most
grateful. Thank you. I will do as you have suggested.

That's how free software works. And probably not just free software,
most software works this way - software is released, bugs are found,
bugs are fixed in a new version or a seperate update.
I know that people are working on ways to actually prove that software
is secure, but I haven't heard anything that would indicate that this is
used somewhere.

I have a similar problem. I need to select different printer trays on an HP 8000
DN. No matter what I do, I can't get the postscript output to print on the
correct size paper. It always prints it from tray 3. I'm using RH 7.0 and I've
tried to adjust the printing through the printtool program. It lets you select
"ledger" as a size but this doesn't seem to have any effect.
What is the best way to control an HP printer from Linux? Is there any way to
use the Postscript PPD file? (PPD = Postscript Printer Definition). Under IRIX
for SGI's, you can get the printing system to use the PPD file that is freely
available for most printers. The PPD file has special commands to control
various features of specific printers. It's usually available from the pritner
manufacturer.

Hi !
I'm relatively new to Linux. I'm running RedHat 6.2 and I'm doing some
development under KDE. I need to use a program to check memory leaks, so
tThis morning, i try to install Debauch but i can't find clear instructions
to install and run it !!
It's probably not really difficult but i don't have so much time to search
for.
I try make all to see what files will be created, but there's this Imakefile
that suggest me that something else should be done. And the README file is
not really clear about that, they just talk about shell script...
Can somebody please explain me "how to install" and "how to use" Debauch ?
Thanks

I need a scrip so that one computer is shutdown by another over a network
connection.
How can I do that.
Probably I have to open a socket where the one computer is waiting for a
message from the other to shutdown.
If I shutdown with a delay are there automatically broadcast messages
created to be read by all users on the system?

This was due to bugs in the 2.2 Linux kernel. It would simply not
compile with modern compilers like gcc 2.96-rh.
Did you set "export cc=kgcc" when compiling the kernel? Another
alternative is specifying "HOSTGCC=kgcc" in the top-level Makefile.
Kernel 2.4 has this fixed, so compiling kernel 2.4 with gcc 2.96-rh
works like a charm.

Patching the machine is a valid option when you're the only one
maintaining it, but in most cases not when you share that responsibility
with other people or when you have to make it easy for another person to
take over the maintainership.
If you mix too much, even applying security updates become a problem -
which ones of the fixes apply to your system? The Red Hat 7.1, 7.0 or
6.2 fixes, or the ones for Mandrake since you maybe at one time
installed Mandrake packages on your Red Hat system?
My opinion is: If you suddenly feel that you want something that a newer
version of your distro has, upgrade to that version of the distro. Most
likely you'll also want other software that also comes with this newer
version of the distro, and something like installing packages for a
newer version of the distro on an older version of the distro is almost
never guaranteed to work.
If you upgrade and install carefully, at regular intervals, and try to
stay with the packages done by your distribution vendor, you will avoid
most of the administration headaches. Also don't forget to apply
security updates as soon as they are released, and subscribe to your
vendor's security announcement mailing list so you know when they are
released.

The easiest way would be to use ssh, setup an account which uses key
exchange
to enable remote login without password. This account needs to be
enabled
to use the shutdown command, normally only root can perform this and
direct
root login should be disabled. "apropos ssh" should show you all man
pages
on this topic on your box and the net is full of how to setup this.

rtfm (read the fine manual) "man shutdown".
Good luck

As for secure: It doesn't listen on the network by default, has no
services open to the network by default, and includes a firewall by
default (if you do a new install).
As for stable: This depends if people find any serious stability bugs
with kernel 2.4. AFAIK, there are none known at this point.
My opinion is that upgrading is always worth it in the long run: You get
new versions of most software, you get new features and old annoying
bugs fixed, and if you get problems, you can give people a precise
answer when they ask what you are running when you have asked for help.

I'm not sure exactly where "elsewhere" is, so I can't look at what you've
previously posted, and can only make guesses as to your config. If I'm
wrong in those guesses, I apologize...
If you have a dulpicate hard drive for backups (same model of drive, I'm
assuming, since you use the word "duplicate"), why not do something simple,
such as....
dd if=/dev/hda of=/dev/hdb
That would make a bit-for-bit copy, meaning that in the case of extreme
failure, you swap the drives, and you're running again. Of course, fiddling
with the block size would speed it up. And, of course, if you were to put
the second drive on a different controller than the first, that should speed
things up as well.

Are you really calling tar from a script or from a C program?
Shell-script return codes are only the upper 8-bits, and
there's no way you should see a return code of 512 in a shell
script.
If it's a C program, then the "return code" mentioned in the
info pages is returned in the upper 8 bits of a 16 bit number,
with a signal number in the lower 8 bits:
512 = 00000010 00000000
return code signal number
Return code == 2.

So it's not that that's doing it, then. But now I'm curious as to why you
set hostname to "home.com" in .slrnrc when it's actually "osyd"...
Oh, hang on, now this one's from "[EMAIL PROTECTED]". Looks like you've
already solved it.
What do you get if you set hostname in .slrnrc to "ntlworld.com" and

Reply-To: [EMAIL PROTECTED]
I have an RH 6.something box that works just fine - has been working just
fine for over a year. I just recently acquired a standard issue laptop
running Windows 98, but I've found that I can't telnet from the laptop to
the RH box. When I use a(ny) telnet client on the Windows machine, it
connects and then hangs. In the RH box, in /var/log/messages, appears the
following:
telnetd[27627]: ttloop: peer died: Invalid or incomplete multibyte or wide character
I can telnet into the RH box from other systems with no problems, but not
from this laptop.
Anyone seen this before? Is there a fix? Should I be posting this in a
Windows NG (since it actually sounds like a Windows problem)...

You do want to copy the entries for /dev (unless you use devfs), but cp does
not copy devices correctly. What I use is rsync, which has a -x option to not
cross file system boundaries (ie, skip /proc since that is a mounted file
system, and to skip the filesystem you have mounted /dev/hdb on). What you
want is something like (if /dev/hdb is mounted on /backup):
# rsync -ax --delete --execlude='lost[+]found' / /backup/
Rsync will only copy the files that it thinks are modified. Another way to do
it is:
# cd /
# umount /backup
# mke2fs /dev/hdb
# mount /dev/hdb /backup
# tar -clf - . | tar -C backup -xpf -
which transfers everything.
If you want to tar, gzip, and split it into smaller pieces so you can copy each
piece to a zip drive (or CD-R), you can do:
# cd /
# rm -f /backup/root*
# tar -clf - . | gzip -6 | split --bytes=95m - /backup/root.gz-
where it will break it into 95 megabyte pieces starting with the prefix
/backup/root.gz-*. If you want more compression (but slower dumps), use gzip
-9, or bzip2 -9.
