Hello,
I just made a typo and did this:
chown -R nobody.nobody /
I ctrl-c-ed it pretty quicklyy, but still, some stuff in /usr was
changed already.
So I did this: chown -R root.root /usr/.
The first problem I noticed is when I try: rsh <any host>
The error message I get is: rcmd: socket: Permission denied
I can't find the cause of the problem, does anyone know where I should
look?
Thanks,
Otis

Easy fix is to buy System Commander (~$50.00) and install it. It will see
you two OS and allow you to chose. Must have Lilo on the root partition of
Linux, though. I used it several years ago wity 4 OS's ; WIn3.1, DOS, OS/2
and Linux. It is very smart and easy to use.

Because this will run "grep" once for each file found;
the "xargs" version will run "grep" many times fewer.

Which is a myth. For example, using WinNT as a ftp server is
vastly less secure than unix. (I've recently run into a WinNT
implementation that lets _anyone_ connecting by anonymous ftp
read and over-write just about any file on the machine.) There
is no such thing as a secure operating system: Too many of the
details depend on the users and system administrators. VMS is
supposed to be a more secure operating system than unix, but
VMS used to ship with (and some VMS machines still have) an
account called FIELD with a password SERVICE. At the operating
system level, the important thing is (1) that problems get
reported, fixed, and that everyone involved hears about it
and (2) the default installation doesn't contain serious
security problems. Unix operating systems as a whole are
generally quite good about that.

Unix machines don't go down very often. With FreeBSD, you can
boot in single user mode, and never have to use a password or
su, until the next time your machine goes down. My FreeBSD machines
only go down after power failures or when I take them down for
upgrades. (I don't run in single user mode, but that's because
I don't see any need to, and one of my boxes is a multi-user
machine.)

I think you are missing some basic facts. For ftp and www services,
there is an enormous difference between getting data from another
machine and allowing your machine to let other people connect.
A machine that can't do the former is disfunctional (as far as
most people are concerned); a machine that can't do the later
might be fine and would probably be more secure.

Again, I think you are missing some facts. Network access depends
on the configuration files and which daemons you start up when
the machine boots. This is not a kernel issue. The sort of options
you mention are things that a system administrator could set up
under FreeBSD and would only take an extra step in the installation
code for any idiot to select. This really isn't an operating system
issue.

Slackware ships with KDE.
TurboLinux shipped with KDE< then shipped without it, then put KDE in an
update, and I don't know the current situation.

I believe that this is correct.
2.2.1 had significant bugs, although I don't recall that this was supposed
to be one of them. Still, it has been out of date for more than 2 months.
Have you tried 2.2.7?

I wouldn't find it uninteresting; taking the system down hard also denies
one, in one's capacity as administrator, to review the logs of the event
in their entirety. The system goes down - but why did it go down? What put
it over the edge? Can we defend against this in the future?
We want black boxes in aircraft to do as much of the same thing as
physically possible - to go on recording until the airplane physically
comes apart (and even then, as long as possible).

AFAIK 'FreeDOS' does not work with lredir. One alternative is to use
Caldera's DR-DOS, which is free for the downloading for individual
DOSEMU usage. It seems to work well on my system, including using
lredir.

This is correct ("mem=128M" did the trick for me). It is more convienient if
you add this line to you lilo.conf file and run lilo again... that way it is
automatic at boot-time.

No, indeed. First of all, pre-built vs. locally built is completely irrelevant.
None of the packages being part of the operating system has any business to
install anything in /usr/local, with the exception for creation of empty
subdirectories under /usr/local/*/ (for site-specific stuff a-la site-lisp in
case of emacsen). *Certainly*, building from the source package should give
results identical to install from the binary package.

Certainly. The difference between /usr/local and /usr being that /usr/local
is explicitly for site-specific stuff, maintained only by admin. Notice that
if you have a site-specific modifications to the part of OS you don't have
to put it into /usr/local - you can mark a modified package as diverted
and packaging system will take care of preserving it gracefully (with
dpkg/dselect/apt, that is. No comments on RPM).
