Compilation

Windows

Non static

nim.exe c --stackTrace:off  --lineTrace:off --checks:off --assertions:off -d:release -d:windows AsyncPortScanner.nim

Static with size optimization

I recommend using this compilation if you don't know the system (and DLL installed on the system) where the scan will be lanched.

nim.exe c --passl:"-static -static-libgcc -static-libstdc++" --opt:size --stackTrace:off  --lineTrace:off --checks:off --assertions:off -d:release -d:windows AsyncPortScanner.nim

Linux

nim c --stackTrace:off  --lineTrace:off --checks:off --assertions:off -d:release -d:linux AsyncPortScanner.nim

Usages

Default scan

Without any arguments the scan will detect all of your network interfaces and scan all IP on it.

./scan

By default the scan is a TCP scan on all of this ports range:

• 21-25
• 135-139
• 80
• 443-445
• 3000
• 3389
• 5000-5357
• 8000-8888
• 30102

Custom scan policy

./scan -w=1000 192.168.56.1-50:tcp:21-25,135-139,80,443-445,3000,5000-5357,8000-8888,30102

Multiples policies

./scan -w=3000 192.168.0.1-192.168.56.255 192.168.0.1-192.168.56.255:udp:67-68

Note: the default protocole is icmp, it's equivalent of 192.168.0.1-192.168.56.255:icmp.

This scan performs a ICMP scan on the first IP range and UDP scan on the second IP range (on port 67 and 68).

Note: It's better for optimization to use a range of port instead of a list of port ranges (67-68 instead of 67,68).

Multiples IP range

./scan -w=100 192.168.0.1/24,192.168.56.1/255.255.255.240:tcp:1-1024

Options

Timeout

./scan -w=100 -t=3 192.168.0.1/24,192.168.56.1/255.255.255.240:tcp:1-1024

Set timeout to 3 seconds (instead of 1 second by default).

Workers

Workers should alway be set, it's necessary to adapt the value with your computer resources (by default 3000 on Windows, but on a VM Windows i needed set it to 100, by default on Linux is 1000).

./scan -w=1000 192.168.0.1/24,192.168.56.1/255.255.255.240:tcp:1-1024

Print

Print all (maximum verbosity):

./scan -w=100 -a 192.168.0.1/24,192.168.56.1/255.255.255.240:tcp:1-1024

Print filtered:

./scan -w=100 -f 192.168.0.1/24,192.168.56.1/255.255.255.240:tcp:1-1024

Print close:

./scan -w=100 -c 192.168.0.1/24,192.168.56.1/255.255.255.240:tcp:1-1024
