Is there any way to keep users from running daemons?
: Is there any way to keep users from running daemons?
No (if by a daemon, you mean a program that forks and returns while
the child detaches from the terminal).
Yes (if by a daemon, you mean things like sendmail and so on). Don't
give them execute permission on your copy. Doesn't stop them compiling
their own copy, though.
There's no way of killing a program that tries to access a network
socket (actually, there is, but you don't want to know). Or nobody
would be able to run telnet. What you might want to do is firewall
off all ports except official ones.

1. give them a restricted shell.
2. chroot them.
3. do not let them log in.
4. have your own daemon that kills theirs.
5. halt the machine, and tell them that their daemons crashed it.
6. throw the server off a tall building and tell them that their
daemons drove the machine to suicide.
7. use windows (who needs daemons, when you can have satan himself).
8. use mac os (that damned second button confuses users anyhow).
9. convince them that the pacman machine at the laundromat down
the street is really a dumb terminal (tell them the ghosts are
10. threaten them, let them know that big brother is watching
(xsublim is good for convincing them of this).
11. kill the users. make them account for every bit they
send over the network, make them give you od -c'ed script files,
and tell them to file it in your cylindrical inbox on the floor.
12. users need wedgies (helps clear their mind).
Only take the first couple seriously, please!

I need to restrict users doing a su to a selected group of users. Like user1
should be able to su to user2 but not user3 and user4.Iam sure one needs to
use sudo to achieve this. Is there any other way other than role based
access control lists and sudo. iam running Solaris 8.0
I tried to configure this in suo but somehow it doesntseem to work. Any
Thanks in advance
