Examples

Default

Initial ping and scan default 1000 ports

nerum --host scanme.nmap.org

Port scan

Scan default 1000 ports

nerum pscan scanme.nmap.org

Specify the ports

nerum pscan scanme.nmap.org --ports 22,80,443,5000,8080

Specify the range

nerum pscan scanme.nmap.org --range 20-100

Scan well-known ports

nerum pscan scanme.nmap.org --wellknown

Settings

By default, nerum determines the waiting time until packet reception (before concluding the scan task) based on the results of the initial PING.
The initial PING is executed in the order of ICMP Ping, UDP Ping, TCP Ping (on port 80), and if successful, proceeds to the next scan task.
If all PING attempts fail, nerum exits before executing the scan. This step can be skipped by setting the --noping flag.
For other settings, please refer to nerum pscan -h for details.

Host scan

nerum hscan 192.168.1.1/24

nerum hscan <path-to-host-list>

Ping

Default ICMP Ping

nerum ping 1.1.1.1

UDP Ping

nerum ping 1.1.1.1 -P UDP

TCP Ping

nerum ping 1.1.1.1:443 -P TCP

Traceroute

TCP Ping

nerum trace 8.8.8.8

You can specify the interval in milliseconds for faster trace.

nerum trace 8.8.8.8 --rate 500

Subdomain scan

nerum subdomain google.com

Neighbor (ARP/NDP)

nerum nei 192.168.1.1

Specify the network interface

nerum -i tun0 pscan 10.10.11.14

Privileges

nerum uses a raw socket which require elevated privileges. Execute with administrator privileges.

Note for Windows Users

If you are using Windows, please consider the following points before building and running the application:

• Npcap or WinPcap Installation:
  • Ensure that you have Npcap or WinPcap installed on your system.
  • You can check installation by nerum check command. Or Please install Npcap from https://npcap.com/#download
  • If using Npcap, make sure to install it with the "Install Npcap in WinPcap API-compatible Mode" option.
• Build Dependencies:
  • Place the Packet.lib file from the Npcap SDK or WinPcap Developers pack in a directory named lib at the root of this repository.
  • You can use any of the locations listed in the %LIB% or $Env:LIB environment variables.
  • For the 64-bit toolchain, the Packet.lib is located in /Lib/x64/Packet.lib.
  • For the 32-bit toolchain, the Packet.lib is located in /Lib/Packet.lib.
