Quick and portable TCP scanner

Eagle

Overview

Eagle is a quick and portable TCP scanner written in Go. It provides some basic functionality like reading a list of hosts, saving the results to a file, and adjusting the timeout and number of hosts to scan concurrently.

Requirements

Eagle is written in Go and only uses the standard library. Once Go is installed, you can build the binary using Make.

Example:

make linux

Examples

Eagle requires you to provide either a host or file containing hosts to scan, and which ports to scan for.

./eagle-Linux64.bin 
  -iL string
    	Input file containing a list of hosts to scan
  -ip string
    	Single host or CIDR address to scan
  -open
    	Only output open ports (default false)
  -output string
    	File to save the results
  -p string
    	Ports to scan (comma separated)
  -threads int
    	Number of hosts to scan concurrently (default 20)
  -timeout int
    	Timeout in seconds for each scanned port (default 5)

You must provide either a host to scan or list of hosts

Below is an example of scanning a /24 subnet and only showing hosts with port 22 open.

./eagle-Linux64.bin -p 22 -open -ip 10.10.1.0/24
Eagle started scan at 2022-03-26 09:43:05
10.10.1.5:22 Open
10.10.1.2:22 Open
10.10.1.1:22 Open
10.10.1.102:22 Open
10.10.1.100:22 Open
Completed scan in 39.93 seconds

The same scan with the number of concurrent IPs increased from 20 to 50 and timeout decreased from 5 to 3.

./eagle-Linux64.bin -p 22 -open -ip 10.10.1.0/24 -threads 50 -timeout 3
Eagle started scan at 2022-03-26 09:46:04
10.10.1.5:22 Open
10.10.1.2:22 Open
10.10.1.1:22 Open
10.10.1.102:22 Open
10.10.1.100:22 Open
Completed scan in 15.01 seconds
