Attacktive Directory Notes
Attacktive Directory fping  Just like ping , fping  uses Internet Control Message Protocol (ICMP) requests to determine if a host is live or not. However, with fping , we can specify any number of targets, including a subnet, making it more versatile than the ping  command. Instead of sending a packet to one target until it replies or times out, fping  will move to the next target after each request.  We can run the following command to discover live hosts in our target network:                             Terminal                             user@tryhackme $  fping -agq  10.211 .11.0/24  10.211.11.1 10.211.11.10 10.211.11.20 10.211.11.250                  -a : shows systems that are alive. -g : generates a target list from a supplied IP netmask. -q : quiet mode, doesn't show per-probe results or ICMP error messages.     Nmap  We can also use Nmap  in ping scan mode ( -sn ) to probe the entire subnet:  nmap -sn 10.211.11.0/24  -sn : Ping scan to determine which hosts are up wi...
