I think eveything stays in ram until it is full. Then the kernel
starts swapping out old stuff to your swap partition to make room for
new, and once the swap partition is full, it writes over the old stuff
in the swap partition to make room for the new stuff swapped out of
memory. That's if I understood the Linux Kernel Guide correctly. G.

Nay, it doesn't work this way. The reason I noticed it was that I (as
many other humans) had an
alias cp='/bin/cp -i'
and when I tried cp -f, it kept asking for confirmations.

In you can use Linuxconf to configure sendmail. Just type linuxconf in a
console..

Yes, Zipslack is an easy way to get started without having to tackle the
whole partitioning thing. It was the first version I tried. The thing
is, Slackware itself is not particularly easy for people who have only
used Windows. It installs to a command line prompt (unless this has
changed), and further configuration and installation are done by hand.
When I felt
ready to make the leap, "Linux for Dummies," by Jon Hall, was a pretty
foolproof beginner's guide, taking me step by step the whole way. When I
was finished I had a configured desktop with a working internet
connection, e-mail and Netscape. There
are several variants of the book now, so the one I used is now called
"Red Hat Linux for Dummies." I tried other versions, but have ended up
sticking with Red Hat. If you buy a book that comes with a Red Hat CD,
make sure it's at least version 6.2. But the majority in these parts,
(Florida State University), prefer Mandrake. A friend of mine who is a
skilled user of windows and who works as a system administrator, decided
to try Suse and is very happy with it. All these distros will give you
a lot of help when you install them, and will give you the option of
a graphical login like you have with Windows.
Good Luck!

I'm an admin in a group which supports a smaller number of machine's
than Aaron's (somewhere between 500 and 1000) and I'm more in
agreement with him. I can load many Sun's and/or HP's with jumpstart
or Ignite-UX. It's quite easy.
For smaller updates I wrote some perl scripts years ago that can do
almost anything I want.
All of our desktop machines are quite similar, almost identical within
a few classes. This does make life much easier.

Don't do that. All common services should be provided by servers in
locked server rooms, on UPS's and with diesel backup and mirrored
disks. If possible fail-over is good.
Then when a clent machine fails, repair/replacement is trivial.

I see this, and I'm not bothered, and don't try to stop it, but I
won't provide any support (maybe a few words of advice if I'm not
busy). If some group sets up a rogue domain, great, but they have full
responsibility.

There's also a simple perl script called 'install sendmail', look on /n

Your using the wrong "filter" in your printer installation. Using the
Red Hat printtool, delete the existing printer. Then reinstall defining
the printer as a LaserJet 5L. Enable "correct stairstep printing." You
should then get proper printing (including 600x600 DPI). My LaserJet
1100A works well with Red Hat 7 (and previously with RH 5.x and 6.x)
with this setup.

Greetings and Salutations...
1) turn off FTP support completely. I Think, though, that this is
likely NOT something you want done.
2) use SCP or a "secured" version of FTP to connect to your
server.
3) Set up firewalling to only allow connections to FTP ports on
your systems from "trusted" clients. (Not especially secure, but,
keeps the Script Kiddies out).

Hi,
I am trying to install Ghostscript 6.50. I am running redhat 6.1.
When I do "make" I get an error that says "-lXt" could not be found.
This happens when ld is called.
The documentation that comes with gs 6.50, anticipates this type of
error, but the remedy it provides does not work.
I searched the archives and found what I think is the exact same
problem. Unfortunately, I got nothing out of the responses. Someone
suggested that some X libraries where missing, but I don't see how
this could be, unless redhat 6.1 did not contain some necessary
libraries.
Anybody else have this problem?
Thanks in advance for any help.

PS Thanks Dances for the earlier responses. Printing Woes I disappeared

Subject: Sequencing large amounts of files.
Date: Sat, 6 Jan 2001 15:47:28 +0930
Hi,
I am about to move a large amount of files from my Windows system to a Linux
box - largely graphic files. There are thousands of files in hundreds of
directories.
I need to name them all sequentially with a specific naming
convention/mask/pattern. I am fairly familiar with DOS but was not satisfied
with the methods that were offered to me in sequencing these files - all
sorts of reasons. I have only just touched upon the power of scripting in
the Shell of Linux (specifically Mandrake) and would like to carry out this
task on this server.
My requirements:
eg. A directory called 010B050A with the files called 010B050A_001.JPG etc -
note the leading zeros and use of hexadecimal in the numbering. (I also want
to vary the amount of leading zeros depending on the directory). I also want
to leave the file extensions as they are.
One major problem that was not easily overcome (by an OS batching to date)
was the ability of the program to be able to pick up missing sequences. eg.
If I had files numbered 0-603 and there were a couple files missing in the
middle of that sequence (because they were no longer needed and deleted),
the program still added them to the end of the sequence instead of filling
the gaps. It doesn't matter if the numbering of each of the files change -
it also reduces the amount of time the program takes to renumber and re-sort
the files - instead of doing 600-odd files it only changes two or three
incorrect ones.
Can anybody demonstrate to me a script that will allow me to do the above?

That is a newsreader in the sense that a half-decayed maggot-infested

You can do just about anything you want in emacs. Read news, write
programs in C or Perl or Emacs-LISP, manage your files (think "Midnight
Commander on steroids"), read and write E-mail, and edit text (including
HTML, XML, and various other non-binary formats.) There is support for
detailed scorefiles, and you can create custom headers and/or
sigmonsters with a bit of Elisp hacking.
>What news readers do you all use?
slrn is nice. But then, I don't visit binaries groups or care about
having pretty buttons to click. Its utility adjunct "slrnpull" is
extremely nice if you're on a dialup connection, and lighter-weight than
leafnode. It's not quite as customizable as emacs, and you have to
write any scripts in S-Lang instead of Lisp, but there is a facility for
calling external commands.
(Really, I use it because it was easy to change its default post editor
to vim...)

Commercial drive image software. Pfft. Above hack works on any
filesystem Linux can write to safely, remove the first 2 lines and it
will work on NTFS, BeFS, or FooFS2000 since dd works at the sector
level. Additional fiddling with verification of read/written data is
left to the reader since I'm tired.
(Warning: /dev/hda1 is only 1G on my system; doing this with large

http://deja.com/home_ps.shtml and search this NG for "lfs.html" as it's
been discussed to death already. Or use a tape device instead of a
file, if you have one and recompiling the kernel and libc is too much
hassle.)

Jumpstart seems slightly easier to automate than Ghost, but a little
fiddly to set up initially. Ghost is good, but seems to need a little
more interaction. It should be easy to set up a semi-automated FTP
install for *BSD or Linux as well. The nice thing about PCs is that
you can make the vendor configure them for you :-)
You might like to look at sup, rsync or cvsup for live updates.
Sup is an old CMU package (Software Upgrade Protocol) which does a
quite good job, but it's a bit dated and isn't actively maintained.
Cvsup seems to be the successor to sup, and uses a number of lower-level
methods (including rsync) to keep the bandwidth utilisation down.
Rsync works nicely with NT as well.

Not always practical with geographically dispersed n-tier systems.
The closer you can get to this the better, though.
Using ssh & sup makes it *really* easy to administer remote *nix boxen,
though you could come close on NT with ssh & rsync. NT Server does
have a tendency to lock up entirely, but not especially frequently.
I'd go one-up on the mirrored disk at the data centre and aim for
enterprise storage of some sort.
A remotely-mirrored contingency site is nice, too :-)

It's really easy if you can use diskless clients or X Terminals ;-)
They seem hard to come by these days, though :-(

Just to close the loop: I found that startx still works when logged in as user.
It sometimes takes two or more trys. I was stopping after the first time it
failed. So put down the short sword, you didn't put me out of business
completely. Having said that, it always use to worke on the first try.
Now, if I can just figure out how to get the GUI login screen to come up I
think my problem may be solved.
Thanks for the attempt.
