I have installed a software that can create multiple daemons that users can use for script caching. But, I`m looking for a way to restrict user access for it`s own daemon. So, basically, x user won`t be able to access y user`s daemon. Also, I would need a way to be able to restrict a user to use multiple daemons. Is this possible ? I saw that grsec patched kernel has this ability and several other security enhancements, but I read some topics about it, and some said it really lacks performance. Is there any other viable solutions ?

PS. I`m using CentOS, so would appreciat some solution that works on it.

for the user x cannot access user y daemon if you can put it in there home dir and chmod 700 to all home dirs.

for the multiple user daemon create a group and add the users to it and chown rootnew group) daemonname
and chmod 770 daemonname


as far as grsec i would recommend staying away from it unless you are really paranoid about security. like me =)

grsecurity is very nice but it takes alot of time to get running exactly how you want it and if you add programs to the system you get to change your policy again and again.

if you want to try out grsec i have a my distro that is almost done and it has grsec built in.

How can one chown a process ? The soft can create multiple streams, a sort of local http server ( but on different ports ) that users can access. So I can`t just chown the file. Waiting for reply. Thanks

sorry bout that. i thought that the certain users just needed to stop/start the daemon. off the top of my head i can not think of a way beside grsecurity or selinux

Luckly, the daemon was made with a -u username command, so only those users can access the daemon, and it works No more need for grsec.

Thanks though for the suggestions
