because Nesssus required Company email account ,but i not .so we can selected the free version only for home ,cna only scan you local home.the we shut down the nessus and use the command " /etc/init.d/nessusd stop。
after indtall the plung。we can use it to scan the web vulnerability but it only for home not for business
2、use the Scapy to find the live port
first let's we see the default configuration use function display() ，we can decide the ARP()=another
arp_request=ARP()
and then use the arp_request.pdst() to define the target ip address
for example " arp_request=ARP() arp_request.pdst="192.168.2.2" then you use the command sr1(arp_request)
also can use the brife command sr1(ARP(pdst="192.168.2.2"))
and then set the toimeout ,you can use the command sr1(ARP(pdst="192.168.2.2" ,timeout=1))
