Hmm...
Why is it that when I use the MAKEDEV script to make a new /dev
directory I only get 706 files, but when I look in my Red Hat 6.1 /dev
directory I get over 2300 files... This doesn't mean that I'll need to
'mknod' almost 2000 files does it...???*s*
The MAKEDEV options I used are:
MAKEDEV -v generic

Subject: Error - cannot find the ppp daemon
Date: Tue, 04 Jul 2000 06:30:03 GMT
Hi,
Well this is strange. I've just done a fresh Red Hat installation (not
my first ever - I've been using it for about 6months) - and I'm getting
'Error. Cannot find the ppp daemon'. Typing 'dsemsg' I see 'PPP line
discipline registered', and checking usr/sbin I see kppp is there. When I
click on that it says that 'kppp is already running under process -ID 758'.
What is the problem, anybody?? I don't think I installed Samba. Would that
(or missing some other similar package, though I think Samba was the only
one not installed) have something to do with it. I encountered this
problem once before, and I think I beat it by reinstalling with virtually
everything... fun.
Why would this problem be encountered with a very vanilla-type
installation?
This is urgent, please.

Subject: How-to PATCH
Date: Tue, 04 Jul 2000 06:35:48 GMT
Hello ..
I know this may sound dumb, but I can't seem to apply a patch. I have
read the man pages, etc.
Basically I do a 'patch < patch.tar.gz'. It gives me a message telling
me that the patch file contains garbage (or something like that).Is
this incorrect or is the file corrupt? Do I have to be in the same
directory as the file I wan't to patch. I think I have also
tried 'patch -p<n> patch.tar.gz'.
This is probably a real newbie question, but I couldn't seem to find
any answers (and the man pages are a little vague). Any answers or
links to resources would be greatly appreciated.
Thanks

I appreciate the response! Thanks!
I visited the Ghostscript site, and I DID see reference to an "stp" driver
that supposedly works for the Epson Stylus Photo 700, but I can't seem to
find it. The only thing I can download from that site is what seems to be a
standalone program that is actually a plugin for GIMP that prints to that
printer. I haven't downloaded anything yet -- do you think the driver is
somehow bundled with this program? Any idea how to get it to work with the
printtool that comes with Redhat 6.2?

Hi there,
How is linux installed from a distro? For instance, is the packages
kept as an image, or is it compiled from source everytime the distro is
installed on a new system... I can see doing a new compile being a very
good option, hence, the software can probe the new system in attempt to
customize the kernel, and other programs, to work better on that
partitcular machine... But to do this, the library files, sources,
compiler and other required "compiliation" utilities need to be
available...
Someone told me that Red Hat just installs everything from a binary (RPM
I guess) image. Maybe the boot disk provides an interface to activate
the CD so that it acts like a working system to install and configure
the new system...
I've read over the various "projects" (such as linuxfromscratch, and
diylinux), and I noticed that these all have to be setup and installed
from an existing, and fully functioning, distribution (with libraries,
compilier etc...)....
I'm just wondering how this can be done while installing from CD...
Thanks for your time...

Hi,
I've noticed that 'makewhatis' distributed with RH6.2 (man-1.5h1-1 RPM)
does not allow for manual pages directories mounted from another host,
read-only, which, especially for '/usr/local/man' is often in
networking environments.
'makewhatis' is run every day by cron, so the sys-man keeps getting
messages about not being able to write 'whatis' database on those
directories.
Below I put a very simple patch to 'makewhatis' to make it check
whether the directory it is about to process is writeable.
regards, Michal.

Date: Tue, 04 Jul 2000 09:57:18 +0200
Hi
If you execute a program, it nomally will run with your privileges, it
uses your UID and GID.
Sometimes it�s necessary that normal users have to execute programs with
root (or other users) privileges and that is what the setuid bit does.
If it is set, a program isn�t executed with the rights of the caller but
with the rights of the owner of the file.
You can change the setuid and setgid bit with `chmod [+/-]s <file>�
If you want to restrict dialout to certain users, make pppd owned by
root:dialout (or another special group) and set the setuid and setgid
bits. Then add all allowed users to the group dialout.

Decompress the file.
tar zxpvf netscape-v600pr1*.tar.gz
It will create a new directory claled "netscape-v600pr1..blahblahblah"
Go into the directory (cd netscape-v600pr1*) and look for an executable
file. I don't have it on my system so I can't tell you what it may be
called. Most likely, there is a README file which will have
installation instructions.
Two likely installation procedures:
./configure
make install
OR
./install.sh

Nope. ANSI wrote more standard than just the one, you know. The ANSI C
standard is one; the ANSI escape characters are (I presume) from
another, and have nothing to do with ANSI C (now by preference called
ISO C, btw, since it was ISO that did the last standard, ANSI being one
member of ISO).
FWIW, my computer (an MS-DOS box) will not display ANSI escapes as
intended, even though I compile ANSI C all the time.

The setuid bit makes an executable run as the user who owns it, regardless
of who is actually running it. "chmod u+s pppd" will make pppd run as root
(assuming root owns it), no matter who actually runs it. "Setuid" is a
contraction I guess, of "set user id". You can also "setgid" executables
(with "chmod g+s pppd", for example) so that they always run as the
group that owns them.
One thing you could do be to to "chown root.wheel pppd", "chmod u+s
pppd", "chmod o-x pppd", and then add users you trust to the wheel
group. This way pppd will run as root, but only users in the
wheel group will be able to use it. (You could make a special "ppp"
group for this purpose, too).
This whole situation arises because pppd needs root-level permissions
in order to be able to do its thing. Wouldn't be a problem if only
root were going to run it, but that's not practical, for obvious
reasons. Man chmod (also man setuid for the setuid system call;
it's pretty readable as far as these things go).

Have you tried unpacking the patch package ?
at the command prompt enter:
mkdir unpack
mv patch.tar.gz unpack
cd unpack
tar -zxvf patch.tar.gz
now a new directory is created, enter that and read the README
file that is most likely there for further instructions

They are precisely right, and you have a slight misperception which
mostly amounts to symantics.

The ANSI/ISO Standard for the C programming language does not
include the ECMA-48/ISO 6429/ANSI X3.64 Standards for terminals.
However, the real problem is that on different platforms
(different Operating Systems or even perhaps different compilers
on the same OS) any functions which are provided specifically
for manipulating colors on the terminal screen are *necessarily*
non-portable (and hence non-ANSI/ISO Standard C) if for no other
reason than the fact that Standard C itself has no notion
whatever of a terminal screen, much less what color it is!

Typically that is done using the terminfo (or termcap) database to
determine which escape codes your particular terminal recognizes
(and indeed, if it even has color). Probably the most common package
to do that with is ncurses. All of the above means that such a
program cannot be a strictly conforming (in the pedantic sense)
ANSI/ISO Standard C program. Typically the way to handle using such
non-Standard code is to separate it into a platform specific module
and compile different modules for different platforms.
If you would like to see a demo program illustrating how to use
the terminfo data base (without invoking the entire ncurses package)
to determine terminal characteristics and terminal attributes
such as colors (and others such as cursor addressing etc.), just
say so and I'll email you such a program. It isn't terribly long,
but a bit more than commonly is posted to a newsgroup.
