Thanks; good idea, that's certainly what the errors say, but it looks OK to me.
This is what I have (below) – does it look right?
I'm not sure why there are mixed permissions on the various rrd files, but
since ntop runs as itself ("ntop" user), it all seems OK.
I also get a lot of these, in /var/log/daemon.log:

Subject: R: [Ntop] debian ntop + rrd errors
It is likely that the user from witch you run ntop does not have read/write
permission upon the rrd directory or ntop installation directory, try checking
the permission of /usr/local/share/ntop (the usual install dir) and its subdirs.

Ogg: [Ntop] debian ntop + rrd errors
I installed the Debian ntop package, Version 3.3-11+b2, and it runs fine, but I
don’t get any of the rrd graphs.
In syslog I get the errors below, lots of them!!
Any ideas what is wrong? The rrd data files seem to all be there.
