yeah, i good idea, i have hundreds of hits from a sympatico user also, tho
is a different city apparently (Toronto) , if it's the same one it implies
they went through severla hundred IP's in 4 days, possible, but i doubt
it, One thing to note tho, i also have a lot of lame server messages for
sympatico.ca looking up reverse, so do NOT trust the names, block by IP
number..

Lame server on '43.227.228.64.in-addr.arpa' 
(in '227.228.64.in-addr.arpa'?): [204.101.251.1].53 'dns1.sympatico.ca'

Yes, proftp can allow/deny based on client IP, tho with ip / vhost kludge
it gets a bit tricky


                <Limit LOGIN>
                        Order Allow,Deny
                        Allow 195.200.31.220
                        Allow 212.32.17.0/26
                        Deny ALL
                </Limit>
(this can be above virtual for server wide, or inside for IP specific
access restrictions)

You can also have a seperate one just for anonymous...
