what i get clear from that report is just about 3 of 1000 my port is open.
but what to do with "telnet" and "BusyBoxtelnetd" also "ISC BIND Hostmaster" ?
is that port need to open ? 
how to close it? on my router no port filter.

running :Linux 2.6.X | 3.X  
but i'am running zenmap on windows 7 64 bits.
