Thanks for this !!
Well, I can find the command 'Setprivgrp' requires 2 parameters (Group ID and preiviledges). But, how can I remove the previledges for a particular thing (i.e. Kernel).
Even, I do not want to remove all the previledges for that group. I want to remove the previledges only for Kernel.
Will the 'CHOWN' command work out, any idea ?

Thanks,
Rohit..

We are going back to the same question. Is the problem having anything to do with the permissions on /stand/vmunix? If the problem is with permissions on that file, then yes, the chown command will work.

No.. I was asking how to set the permission for only kernel with 'setprivgrp' command.
As per I know, we need to give the file or directory name to provide previledges, but as for 'setprivgrp' command, we do not have any option to provide only for one file/dir. So, I want to know how can I revoke the previledges only for kernel, not for rest of the files or options for that particular group.
It will be helpful if you can explain the answer with an example.

Thanks,
Rohit..

Since noone answered in 23 hours, I will ask : what kind of group control Kernel and what is your system ? Basically, you can alter kernel values, where applicable, only if you are root user.

I'm sorry, but I can't give examples (no access to any HP systems). You can get the existing privileges that a group has using getprivgrp. Then using setprivgrp, remove the permissions that are not required.

I can't get more specific than that, sorry.

Yes, I also think so.. Anyway, thanks a lot for your help.. Please let me know if you get any update regarding this.

Thanks,
Rohit..

The problem is one of the group ID is having kernel access. I do not know how the group is having previledges to kernel, whereas no other groups are having this kernel access ? I need to revoke the kernel access/previledges of that particular group.
The OS is HP-UX and version may be 11.0.
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 ? If you know any command for this, then please let me know in details with an example.

Thanks,
Rohit..
