thanks for the replies,
after checking through your questions i had the permissions wrong, and trying to run the program using ./bin/ktest1 instead of /bin/ktest1
Is there any loopholes that i should be aware of when giving users access to this command i have heard that you can add a no breakout command is this wise? basically how do i ensure that the user cannot use this to gain more privilidges?
i am currently using
Kernel Linux 2.6.25-14.fc9.i686
