NET-scan

.NET cli multi threaded host discovery tool (and port scanner ... at some point ..eventually).

scans a subnet range for a specific port and report hosts having that port open

simple exemple commands:

net-scan.exe hosts -r 192.168.1.1-254 -p 445

net-scan.exe ports -h 192.168.1.5 -p 5000 

port scanner :

net-scan.exe ports -h 192.168.1.5 -p 5000 -th 300 -t 1

=> scans ports on 192.168.1.5:
    first 5000 ports
    with 300 threads
    1s timeout

host discovery / scanner:

exemple :

net-scan.exe hosts -r 192.168.1-2.1-254 -p 445 -th 100 -t 5

=> scans from 192.168.1.1 to 192.168.2.254:
    with 100 threads
    from 192.168.135.1 to 168.235.254 
    port 445
    5 seconds timeout

less threads , more timeout = more accurate results

release and usage :

drop the net-scan.exe on a machine you have a shell on and use the args above to start the scan.

i highly recommand compiling your own executables from code in VS :

compile with NET 3.5 for windows 7 and NET 4.5 for windows 10

BUT .. as some are lazy enough to not do that and willing to run a random .exe from the internet there's the release folder.

todo list:

• clean the ugliness (made in few minutes in a hurry so sorry xD)
• scan from CIDR
