no - the correct answer is this:
The Redhat maintainer did not bother to read the release notes for ncurses.
The current version of ncurses is 5.2 (20001021)
There's an faq at
http://dickey.his.com/ncurses/ncurses.faq.html
(The faq has links to the release notes for 4.0-5.2, note that interface
changes are listed at the beginning).

Install and use the equivs package to create a dummy package. Are you sure
that you need to, though? sendmail 8.11.1 is available in unstable. Put
deb-src http://http.us.debian.org/debian unstable main
in your /etc/apt/sources.list, run 'apt-get update', and then run
'apt-get source -b sendmail' and apt will download the source and build a
.deb for you to install with dpkg.
You'll also want to install sendmail-doc.

Look in /usr/share/doc/portsentry-1.0.
Config files are in /etc/portsentry. Pretty self explanatory. I didn't change
much besides how it already came configured by RH, except the KILL_ROUTE
command.
I get that authorized scan too from att@home. Portsentry adds the IP address of
a machine susceptible of scanning your ports into /etc/hosts.deny. You can
configure it to send you e-mail when something happens, or to set up an IP
chains rule. You can see the actual commands portsentry executes in
/var/log/messages.

It is in the 2.4.x kernel, but it also needs a glibc2 that has been
compiled for 64-bit FS support too (so that it knows about the open64
etc. system calls). You also get 32-bit uids and gids with it.
glibc2.2 on a 2.4.0-test11 kernel was happy to create a 5GB file for
me (although compiling and linking with an "uninstalled" libc is an
interesting exercise...).

The drive is a 6mth old 20GB Quantum one (hdb) and I played with hdparm
when it was first installed and have it running up to 3.45 MB/s (setting
DMA on causes drive corruption even though it shouldn't but that is
another story :) Since machine A (jukebox) has 2 drives I tried moving
an mp3 from hdb onto hda (which is running @5.65MB/s) and then playing
it while accessing a large file from hdb.
alas again the slowing down, even though the files are now on seperate
machines. thanks for the idea though, I might have another play with
hdparm and see what I can get going...

My network (at the moment anyways) is the ultimate! The single red
crossover cable! :)
The mp3's are not actually playing over the LAN they are playing from
the machine, the large file access is over the LAN, but I see your
point.
This has given me some ideas though to check the network...
-open a SAMBA share on the jukebox machine instead of the win2K machine
and read a large file.
-run iptraf to see how much traffic is being generated by the smb work.
-do some FTP between the machines while playing an mp3 to check the
network.
hmmmm! things to do, post-work :]

You've set yourself up to so much flame...
No help? Try "man man" for starters. Or "xman".
(Although admittedly, some programs do come with very little or outdated
documentation. Open source comes at a price I guess).
Obviously you must configure pretty much everything. That's one of the points.
We want to KNOW what a program does, as it pleases us, not the way some
"omniscient" designers from some big software corporation have decided. (My
favourite quote: "Where do they want you to go today?").
Use emacs for programming. It's designed for that and much more. It even has
builtin support for the debugger. If you configure it right, you'll start to
like the programs you write.

Besides that, there is a man page for everything under the Sun. A quick look at
man man reveals that man uses less as the default pager. Turning to man less,
one finds all sorts and kinds of neat search options.

Don;t complain about lilo. Complain about your bios. It is what cannot

In case you have a new machine ( <1.5 yrs old) which has a new bios

Read the man page for su.
When su is invoked with the '-' option a login environment for
the new userid is provided; and otherwise the current
environment is retained and the PATH variable is reset.
Hence without the '-', and absent something in the shell init
files to set PATH, the effect of doing a bare su to another user
is to reset the PATH variable to /bin:/usr/bin.
If you want to access root *with* the normal login environment
of root, invoke su with the '-' option: "su -". That of course
assumes that root does have a properly configured set of shell
init files...
For larger systems with multiple system admins each of whom
might want a different environment when working as root it makes
a lot of sense (and this might also be true for those who just
can't type a '-' after "su") to arrange their own init files to
catch the fact that su has just reset PATH, and re-initialize it
to whatever is wanted. Use something like this in your own
~/.bashrc file:
#
# reset the PATH that su sets
#
if [ "${PATH}" = "/bin:/usr/bin" -o \
"${PATH}" = "/bin:/usr/bin:/sbin:/usr/sbin" ]
then
export PATH="..." # replace ... with desired path
