Solaris error messages "Not Owner"

Gotta love the Solaris 10 error messages

"unable to chroot to /opt/dns/dnsbl/: Not owner"
"unable to setuid(341:65534): Not owner"


What it actually meant was "You don't have the PROC_CHROOT privilege" and "You don't have the PROC_SETID privilege" but it wasn't exactly a straight forward google to find that out!

Not owner

I am new to solaris and i don't quite understand the 'privilege' your are talking about.
What should I do to make my "chroot" work?

Re: Not owner

Oliver,

I stopped working much with Solaris a few years ago, so I'm a little rusty.

Solaris allows you to assign parts of the root privileges to a user:
http://www.softpanorama.org/Solaris/Security/solaris_privilege_sets.shtml

Now the other thing to remember is that not only can you assign this to a user, you can also assign it when writing Solaris service manifests. Resulting in processes running as root, but without full root privileges, or running as non-root with the ability to chroot, bind to low ports, etc.
