Hannah:  I think Dumbledore always knew, or strongly suspected it 
was Riddle the first time.  By the time Riddle had become Voldemort, 
it was confirmed to DD.  When the attacks began again, DD knew it 
must be LV behind it, as he is the heir, and has no children of his 
own.  But he doesn't know how LV is achieving it, as he says to 
McGonagall.  I always find it a bit hard to believe that DD couldn't 
have worked out a bit more than he did, given his supposed 
omniscience.  That's never sat easily with me.  If he was doing it 
to test Harry, it was a massive risk.  It was only luck that none of 
the students attacked actually looked the basilisk in the eye.  I 
suppose we have to accept that he really didn't know how to solve 
the problem, unless we subscribe to puppetmaster!DD.  And even for 
him, that would be a very large risk, which didn't pay off terribly 
well.

Hannah:  I reckon the Dursleys were trying it on, to see if the 
protection thing still applied.  I think they know at least 
something of the protection, but maybe not how long they need to 
carry on offering it.  They may well have assumed they no longer had 
to carry on with it now Harry was at Hogwarts.  I think Harry does 
have to go back every summer, as Dumbledore says.  If he skipped a 
year or two, they really would be forcing the definition of 'home.'  
I think the four-six weeks a year he spends there is the absolute 
minimum as it is.
