Aircraft
Uneventful takeoff in clear conditions.  During climb; a Flight Attendant called flight deck to describe foul smelling odors in the cabin.  Although there was a brief smell of odors on the flight deck during the initial climb; they were gone just as quickly; not to return for the rest of the flight.  Stopping the climb at FL310; we consulted the QRH and called Dispatch.  In a attempt to clear the cabin; we secured the #2 pack.  Initial cabin reports were that the situation improved so we continued toward our filed destination.  After a few moments the fumes resumed and conferring with Dispatch; we changed our destination to an enroute airport.  Again; consulting with Maintenance Control; we descended to 10;000 feet; secured the #1 pack and opened the ram air valve in order to further clear the cabin with ambient air.  Attendants advised that fumes were lingering and passengers were complaining so we diverted to a nearby airport and landed without incident.  The four flight attendants sought medical follow up from the urgent care clinic in the divert terminal; one flight attendant split off the trip; returning to her home base complaining of 'symptoms' and all others continued with the trip.  To my knowledge; no passengers sought or asked for medical treatment.
An A321 Flight Attendant crew reported a foul smelling odor and; after consulting with Maintenance; the #2 pack was secured. Then the flight descended to 10;000 feet and with both Packs OFF finally diverted to a nearby airport; where the flight attendants sought medical treatment.
