ipset: how to run non-root

ipset: how to run non-root

[Mike Wright]

Hi all,

I'm trying to use ipset from a php script on an apache server.

ipset requires root user in order to execute, but the webserver is 
running as apache.  suexec is not a possibility because it won't execute 
programs with root permissions.  It is possible to have a cron job 
perform the task but that introduces a time delay.

I've tried changing ownership of ipset to apache:apache but that didn't 
work.  Still received the "must be root" warning.

I looked into the source of ipset.c but it seems like the socket() call 
must be done as root, and I don't know how to hack around that.

Does anybody know how I might accomplish this?

Thanks,
Mike Wright

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...

Excellent!  Worked out of the box with no problems.

Done!  As a paranoid I really like that advice.

You can also try sudo

better advice would be to leave the bits alone and think of perhaps 
allowing sudo access if really required, but it should be seriously 
considered from a security context.
