rns - Rust Network Scan

• Network scanning tool written in rust

Installation

• precompiled binaries are available for linux_amd64 and linux_arm64 architectures, inside the bin folder, otherwise you have to compile from source
• package pre-requisites for local compilation:

git
cargo
make

Install from Cargo

git clone https://github.com/ryzeon-dev/rns

• enter the rns directory

cd rns

• build the executable

make

• install (requires root)

sudo make install

Install precompiled

amd64

sudo make install-amd64

arm64

sudo make install-arm64

Usage

Scanning

• scan verb can be called by its initial too

rns s 192.168.1.0 mask 24 ports all

Network Scanning

• when scanning for IP addresses, rns will try to resolve the ip address into the host name, using the NetBIOS protocol
• you must provide an IP address, a network mask (ip address or CIDR form) and some ports to scan

rns scan 192.168.1.0 mask 24 ports std

• it is possible to set the timeout (in milliseconds) for both host scanning (checking if the host is up) and port scanning (checking if the ports is open), using the host-timeout and ports-timeout verbs

rns scan 192.168.1.0 mask 255.255.255.0 ports std host-timeout 1500 ports-timeout 500

• to scan certain ports, write them comma separated after the ports verb

rns scan 192.168.1.0 mask 24 ports 80,8080,8088,8808,8888 

• to scan a port range (e.g. from 0 to 999), write the starting port and the ending port (plus one) separated by -
  • remember that the ending port is a limit, and therefore excluded

rns scan 192.168.1.0 mask 24 ports 0-1000

• to scan the standard ports (you can get a description for them running rns explain) use std as argument for ports verb

rns scan 192.168.1.0 mask 24 ports std

• to scan both open ports and mac addresses add scan-mac verb at the end

rns scan 192.168.1.0 mask 24 ports std scan-mac

• only scan for mac addresses use mac-only verb instead of ports

rns scan 192.168.1.0 mask 24 mac-only

• to scan the nmap's standard 1000 ports, use nmap as argument for ports verb

rns scan 192.168.1.0 mask 24 ports nmap

• to export the scan into a Json file, use the --json or -j flag
  • by doing so, all the stdout-communications are suppressed

rns scan 192.168.1.0 mask 24 ports std -j > report.json

• to have a quiet execution, use the --quiet or -q flag, this will output only the final report

rns scan 192.168.1.0 mask 24 ports std -q

Single address scanning

• to scan only one IP address, use the single verb before the IP address
  • note that network mask is not required (and must not be provided)

rns scan single 192.168.1.16 ports std

• all the verbs shown above are valid for single-address scanning

Listing

• list verb can be called by its initial too

rns l interfaces

• to export the listing into a Json file, use the --json or -j flag

rns list ports -j > report.json

Locally open ports

• to list the ports openend on local machine, use the list ports verb, and both TCP and UDP open ports will be shown

rns list ports

• to only view TCP or UDP, pass tcp or udp after ports verb

rns list ports tcp

Local IP Addresses

• to list local machine's IP addresses use list addresses verb

rns list addresses

Local Network Interfaces

• to list local machine's network interfaces use list interfaces verb

rns list interfaces

All Local Machine Network Data

• lists network interface, and for each displays mac address, ipv4 and route(s)

rns list local

Monitoring

• to monitor an interface's activity use monitor verb, followed by the interface's name

rns monitor eth0

• activity is displayed in bytes by default, but using -b or --bit flag, activity gets displayed in bits

rns monitor eth0 -b

Setting

• to set an interface's status (such as up or down), use set verb
  • this operation requires root privilegies, and in some cases running with sudo might not be enough

rns set interface eth0 status up

Help

• run rns help to get help

Version

• version can be checked running rns version or rns v
