Re: ipset: how to run non-root

I never used ipset, but you could use a generic trick:
 Set the owner of the ipset binary back to root and set the suid bit
 which will result in the ability for everyone who can execute the
 binary to do this "as root".

You might want to think about an execution restriction (e.g. via the group)
to prevent people who should no fiddle with ipset from doing so.

I hope you have some access control via your web application...
