Did you try what I had suggested in an earlier post?
netbios name = penguin
I didn't see that line in your smb.conf file.
I haven't used kppp or pppd for that matter so unfortunately I
can't really help you there. I'm assuming you have the symbolic
link /dev/modem pointing to the appropriate serial device.
If you're using Sunfish as the DNS server, that's probably why
things are taking forever when you boot up Penguin. Make sure
you have an entry in /etc/hosts for Penguin (assuming that's
your Linux host name as well.

You can boot off of a disk and just don't use the boot disk when
you want to use Win98. Also, once you have Linux installed, you
can use the latest version of LILO which doesn't have the 1024th
cylinder problem. Then you won't need the boot disk (though it's
good to have anyway).

Subject: Xdm locks machine?
Date: Tue, 06 Jun 2000 22:14:06 GMT
I recently changed my runlevel to 5, so that Xdm would start.
Well, Xdm did start, but I couldn't type anything into the login
screen. Clicking in the Xdm login prompt area, to gain focus,
didn't help. Not only that, but none of the function keys did
anything, so I couldn't switch screens to login. ctrl-alt-bksp
did not abort the Xdm session. Not even ctrl-alt-del worked,
and I had to power cycle.
So, everything I mentioned not working (except Xdm of course)
works just fine when I boot runlevel 3 and use startx.
Why would this happen? How do I fix this?
My system runs Linux 2.0.36 on a fully patched Redhat 5.1 Pentium
machine. I'm using the XFree86-S3V-3.3.5-1.5.x X display driver
with my S3 Virge card.

This is true. It may cost $.05 more to make a Linux CD than a Windows CD.

Then my next suggestion will be that you attempt to zero the partition
table in the MBR of the problem disk.
Some BIOS'es look at the partition table when they calculates the
cylinders/heads/sectors setting to be used. If the partition table is
garbage, or you entered some wrong entries manually, results like the
BIOS translation seen in the Findpart output can occur.
Note that only the first sector (512 bytes) of the problem disk should
be zeroed. Some tools will zero as example 128 sectors, and this will
damage the first partition on the disk.
If you currently have a working Linux you can use the dd command to
write a file containing 512 ascii 0 characters to the first sector of
the disk. Also simply deleting the entries using fdisk might work.
If you have to zero the partition table from DOS, this might work:
set findpart=edit
findpart 2 0 1 - 00 0 0 0 0 0 0 0 299043 1 60 26
findpart 2 0 2 - 00 0 0 0 0 0 0 0 299043 1 60 26
findpart 2 0 3 - 00 0 0 0 0 0 0 0 299043 1 60 26
findpart 2 0 4 - 00 0 0 0 0 0 0 0 299043 1 60 26
set findpart=
findpart 2 table fp2-1.txt
This assumes that the CHS 299043/1/60 translation still is present. A
batch file is in http://inet.uni2.dk/~svolaf/map1.zip
When the partition table is zeroed, you can detect the disk in BIOS
again, reboot to DOS, and run the Findpart search again. The above
output file is just to verify that the MBR partition table was zeroed.

...and did it work, or not?
When do you want this script to be executed? If you want it to be run at
boot time, put the line
/path/to/script -OPTIONS ARGS
in /etc/rc.d/rc.local . It's important to use the full pathname. Also
make sure the script is executable by all (chmod a+x script). If you
want the script to be executed every time a user logs in, put the above
line in that user's ~/.bashrc or ~/.profile.

Subject: Dumb SUID problem
Date: Tue, 06 Jun 2000 13:34:09 -0700
I'm trying to get a small script to run SUID root on a Red Hat 6.1 box.
The script simply prints the output of "whoami", then attempts to copy a
file to a directory owned by root. This is just a small test case for a
bigger job.
I called the script "sid". To set it SUID root I did the following:
su to root
chown root.root sid
chmod 4755 sid
When the script is run as root, it prints "root", and writes the file to
the directory. When the script is run as user 'markm' (non-root), it
prints "markm" and reports that it cannot write the file because
permission was denied.
I'm obviously missing something here. I would have expected both cases
to succeed. If the script is run suid root, doesn't the UID get changed
to root just before the script executes?
Is there some special system setting to permit a user to run SUID root?
Can some kind soul point out the error of my ways?
Thanks,

A lot of people are after windows to linux connectivity via an X
server.
VNC is pretty good, but gets slow when using graphic intensive apps
and needs the vncserver running on linux.
MiX is no longer free and I don't know of any other free X servers for
windows. Does anyone know of any projects at the moment for Open
Source X servers for windows?
If there aren't any, is it worthwhile starting one?

a.) Yes, it is very stupid NOT to include inetd in 6.2 if you do a
GNOEM/KDE workstation install, have no idea why.
b.) mount you redhat CD and go /mnt/cdrom/RedHat/RPMS/ , install the RPM
with "rpm -Uvh inetd*".
c.) Type "rpm -Uvh telnet-server*" and it should install
d.) type "/etc/rc.d/init.d/inet restart" and you should have inetd & telnet
running with no problems.
You should then have everything installed.
This really should work.

SUID shell scripts are a *Security Hole* and Linux will not honor the SUID
bit on a script for a long list of reasons.
If you really need this done, make a C wrapper and make this C wrapper
SUID root. Like so:
/* in file wrapper.c */
#include<stdio.h>
#include<stdlib.h>
int main(void) { system("/path/to/script"); return 0; }
gcc -o wrapper wrapper.c
chown root.root wrapper
chmod 4755 wrapper

Running Communicator or Navigator? I did the 16M, then 32M, then 64M
thing and used to kill NS regularly to reclaim memory. Dropped to just
Navigator and the memory leaks seem to have disappeared. I never kill it
now on 128M system due to memory consumption. It kills itself every now
and then though ;)

Correct. MacOS terminates lines with a single CR byte. UNIX terminates
them with a single LF byte. (And DOS-derived systems, including MS-DOS,
Windows and OS/2 use the two-byte CR-LF sequence).

I wrote a standalone C program to do it.
Some UNIX distributions (but not RedHat Linux, unfortunately) include
text-conversion programs for this: unix2dos, dos2unix, mac2dos,
mac2unix, dos2mac, and mac2dos.
Using tr, this should work to convert single CR bytes to LF bytes.
cat mac_file.txt | tr \\015 \\012 > unix_file.txt

Depends on the type of the file. KDE, GNOME, and most file managers
maintain a list of MIME types based on filename extensions (or green
bytes) so that if you double-click on foo.xls, StarOffice or Gnumeric gets
launched. If you double-click on foo.jpg, ee or kview will be launched.
Text files are read with "less FILENAME", "xless FILENAME", or an HTML
viewer. Executables don't have filename extensions.

The "permission denied" message is because when you typed the name of the
file, the shell tried to execute that file as a program.[0] You don't have
to copy the files anywhere.
Since you seem very new to Unix in general, I reccommend reading a book
like _Running Linux_, which has a lot of useful information and tutorials
for new users.
[0] MS Windows deliberately confuses the act of running a program with the
act of opening a data set (opens whatever random app the system thinks you
should use to open that data set), has a silly notion of "file types", and
hides the file type info (3-letter extension) by default in most of its
GUI tools. No wonder people get confused.
