You don't have to write a suid program, just an ordinary program.
Then let sudo exec it (whenever it fills sudo's rules)
This way your mistakes in the additional program is less security
hazardeous.

I agree that normally the path would be set in .bash_profile.
But I recently upgraded from RH5.X to RH7.0, and I noticed some
strange behavior on that machine, which I haven't seen on others
I've upgraded. For example, if I login as root at run level 3,
and then use startx, I get the expected path as set in
.bash_profile for root in my gnome terminal windows. But if
instead I start in run level 5 and login at the gdm prompt, I get
an entirely different path which omits /sbin directories and
includes some kde directories, even though I am using the
gnome desktop. I tried to track down the problem, but so
far I haven't been successful. I assume it has something to
do with the gdm configuration, but I'm not sure where to set
that. Any advice would be appreciated.

Debian and Slackware both have a basic floppy install
available that runs about 10-20 MB, respectively. Both have the disk
images available on the cdrom; these can be copied to floppies on
another machine using either dd in linux or rawrite in DosWin.
Modern kernels are ~ 5MB, so you will have to go to a
specialty distribution if you have only 4 MB system RAM. With 8MB,
you should do ok.

Is there a way to survive (with Linux) in a Windows only environment?
More precisely, the company is using W2K and Office 2K. There's heavy
usage of Word and PowerPoint attachments as well as Outlook's calendar
function. The only mail server is MS Exchange and does not speak POP3 or
IMAP (AFAIK). File access is provided by Netbui over TCP/IP. There's no
NTP server to synchronize clocks (just some proprietary Windows method).
Could Sun's StarOffice be of help here? Any other ideas?

Most likely you're thinking of vim (which comes standard, I believe, with
most linux distributions).

Did you really use lilo.config? The correct file is /etc/lilo.conf. Then
you have to run lilo after the edit. And sometimes I think a BIOS can't
see more than the first two devices for IDE, and hdc is the third
device...possibly that could be the problem.

Subject: Help--Program exists, but can't execute
Date: Fri, 23 Feb 2001 09:19:52 -0800
Hi:
I have a very strange and serious problem. On Suse Linux 7.0, I have
successfully installed the rpm for Eagle 3.55 (A printed circuit design
program from www.cadsoft.de). However, when I try to
run eagle I get:
~ $ eagle
bash: /usr/local/bin/eagle: No such file or directory
The same error appears if I try to run eagle as a user, as root, from a
console outside of X, from the CDROM demo directory as user or root.
I have verified many things are in order for the program to run:
1. The eagle program (actually symlink to /opt/eagle/bin/eagle from
/usr/local/bin/eagle) is in the user's path and the symlink points to
the right place:
~ $ which eagle
/usr/local/bin/eagle
~ $ ls -l /usr/local/bin/eagle
lrwxrwxrwx 1 root root 20 Feb 23 07:55
/usr/local/bin/eagle -> /opt/eagle/bin/eagle
2. The eagle program is installed in /opt/eagle/bin:
~ $ ls -l /opt/eagle/bin/eagle
-rwxr-xr-x 1 root root 3924300 May 30 1999
/opt/eagle/bin/eagle
3. Trying to run the program using the direct path also fails:
~ $ /opt/eagle/bin/eagle
bash: /opt/eagle/bin/eagle: No such file or directory
4. Creating a token script in /opt/eagle/bin named eagle that simply
echoes that it is executing works OK:
/opt/eagle/bin # ls -l eagle
-rwxr-xr-x 1 root root 40 Feb 23 08:57 eagle
/opt/eagle/bin # cat eagle
#!/bin/sh
echo "Eagle script executing"
/opt/eagle/bin # ./eagle
Eagle script executing
5. Making the token script into a wrapper that executes the real eagle
by a different name also fails:
/opt/eagle/bin # ls -l eagle eagle.sav
-rwxr-xr-x 1 root root 65 Feb 23 08:59 eagle
-rwxr-xr-x 1 root root 3924300 May 30 1999 eagle.sav
/opt/eagle/bin # cat eagle
#!/bin/sh
echo "Eagle script executing"
/opt/eagle/bin/eagle.sav
/opt/eagle/bin # ./eagle
Eagle script executing
./eagle: /opt/eagle/bin/eagle.sav: No such file or directory
Now for the most interesting part:
6. I have a triple boot system with W98, Suse Linux 6.2 (with Eagle
3.55 working fine), and Suse 7.0 . When I boot up Suse Linux 6.2, then
mount the partition containing Suse 7.0, change dir to the
/s70/opt/eagle/bin directory, and run ./eagle, it executes just fine!
Also, while running Suse 7.0 I can't run the eagle from Suse 6.2
What is going on here making Suse 7.0 unable to run eagle and how can I
fix it???
Thank you for help.

Not sure I agree with this. A Theory is not, in itself, repeatable, but the
experiments performed to test the theory are. When one says that science must
be repeatable, one means that if a good experiment is performed to test the
theory, the same (or consistent) results will be obtained every time,
regardless of who is performing the experiment. These repeatable results
reinforce the vailidity of the theory.

Use /etc/sudoers
this is extracted from the man page of sudoers :

The user pete is allowed to change anyone's password except for root on the HPPA
