Here's a summary of all the suggested options
Available programs:
1. sudo (came out tops)
Logs every time they use it and what they did.
This program can be configured to allow some user (or
group of users) to execute either all programs except some, or
no programs except some.
Source is available at
1. ftp.courtesan.com, in /pub/sudo. (If you need a compiler for the
Solaris system, sunsite.unc.edu has a bunch of Solaris "packages",
in /pub/packages/solaris/sparc.)
2. http://www.courtesan.com/courtesan/products/sudo/
3. Linux mirror sites
4. Sunsites - sunsite.unc.edu somewhere out in /pub
5. ftp://ftp.rootgroup.com
6. http://smc.vnet.net.
7. ftp.cs.colorado.edu in /pub/sysadmin/sudo .
2. su1
This program can be configured to allow some user (or
group of users) to execute either all programs except some, or
no programs except some.
3. Power broker..
provides key-stroke login to
monitor the logs of the root-previliged members.
4. "su" (not the one supplied with the OS)
unfortunately this is very configurable and can cause a security hole
5, "op"
lets you create a list of commands that certain users may execute.
6. Super
OR
1. a small C prog will do :
main
{
setuid(0);
do whatever you want to do
}
Obviously you would name this executable something sensible & restrict
access to it with permissions. Be careful though, if, for example, you
run a shell script from the C prog, if that script allows the user to
use "!ksh" or the like to get a command line, then your user has control
of your system. If you are stuck, in ksh you can do this in a script to
set up a safer environment :
(SHELL=/dev/null; myscript)
2. Try using 'ksh' or 'csh -bf' as the command interpreter.
It is not advisable to setuid on a script. Definate security issue.
