Disable requirement for administrative privilege on a particular application.


I am running Fedora 2 on a laptop. Two users exist, beyond the administrator. When a user tries to launch kppp, he is told he lacks "sufficient administrative privileges" and asked for the root password. I want these two users to be able to access the modem without knowing the root password, that is one should not have to be a superuser to use kppp. As administrator, I've tried checking "execute" in the permissions of kppp for these two users but nothing changes. I've heard the solution is to create a group called "dialout" and place those users who have access to the modem in it, but how does this solve the problem of making use of the modem something a non-superuser can do?

Thanks in advance for all suggestions.

After creating the group, chmod kppp to 4750 owned by root with group dialout. What this dows is sets the permissions so that root had full permissions on the executeable and group dialout users can read and execute it. It also sets the SUID bit on the executable. What this means is that kppp will now run as root, regardless of who actually launches it. Needless to say, this can be a security risk, so you should not use SUID a lot. Another way to do this is configure sudo so users in group dialout can execute kppp as root,

Thank you for your prompt reply. Sounds like the second option configuring sudo so users in group dialout can execute kppp as root is better way to go. I'll look into that. Probably have to post again as new to all this (obviously.)
