UNIX for Dummies Questions & Answers

Hi,

I need to know how to revoke the access/permission of Kernel for a group. In details, one of the group 'X' is having kernel access/permission and this group can control the Kernel at anytime. How can we revoke this permission/access ?

Thanks,
Rohit..

What do you mean by kernel access permission? By default, the kernel will run as root. And no one can access the kernel directly, but only through defined access points. Perhaps you could let us know exactly what your problem is.

Also, please let us know your OS and its version.

Sorry for any confusion. The problem is one of the group ID is having kernel access. I do not know how the group is having access to kernel, whereas no other groups are having this kernel access ? I need to revoke the kernel access/permission of that particular group.

Hope it's cleasr now !!

You haven't answered my question.

a. What is your OS?
b. What do you mean by "is having kernel access"? Access to do what?

Okie !! The OS is HP-UX and version may be 11.0.
To answer your second question, the root wrongly provided the kernel previledges to one of the group. I do not know how and where the root has given these previledges ? The particular group is having all the previledges to access the kernel. Now, I need to revoke the previledges for that group, which I donot know where and how to change in the system ?

Thanks,

On HP-UX, the closest thing that I could find to a kernel privilege is the setprivgrp command. You can lookup the man page of that command for more information.
