FProbe - Fast HTTP Probe

Installation

GO111MODULE=on go get -u github.com/theblackturtle/fprobe

Features

• Take a list of domains/subdomains and probe for working http/https server.
• Optimize RAM and CPU in runtime.
• Support special ports for each domain
• Verbose in JSON format with some additional headers, such as Status Code, Content Type, Location.

Usage

Usage of fprobe:
  -c int
        Concurrency (default 50)
  -i string
        Input file (default is stdin) (default "-")
  -l    Use ports in the same line (google.com,2087,2086)
  -p value
        add additional probe (proto:port)
  -s    skip the default probes (http:80 and https:443)
  -t int
        Timeout (seconds) (default 9)
  -v    Turn on verbose

Basic Usage
Stdin input

❯ cat domains.txt | fprobe

File input

❯ fprobe -i domains.txt

Concurrency

❯ cat domains.txt | fprobe -c 200

Use inline ports
If you want to use special ports for each domain, you can use the -l flag. You can parse Nmap/Masscan output and reformat it to use this feature.

Command

Timeout

❯ cat domains.txt | fprobe -t 10

Special ports

❯ cat domains.txt | fprobe -p http:8080 -p https:8443

Use to check working urls

❯ echo 'https://google.com/path1?param=1' | fprobe

https://google.com/path1?param=1

Use the built-in ports collection (Include 80, 443 by default)

• Medium: 8000, 8080, 8443
• Large: 81, 591, 2082, 2087, 2095, 2096, 3000, 8000, 8001, 8008, 8080, 8083, 8443, 8834, 8888
• XLarge: 81, 300, 591, 593, 832, 981, 1010, 1311, 2082, 2087, 2095, 2096, 2480, 3000, 3128, 3333, 4243, 4567, 4711, 4712, 4993, 5000, 5104, 5108, 5800, 6543, 7000, 7396, 7474, 8000, 8001, 8008, 8014, 8042, 8069, 8080, 8081, 8088, 8090, 8091, 8118, 8123, 8172, 8222, 8243, 8280, 8281, 8333, 8443, 8500, 8834, 8880, 8888, 8983, 9000, 9043, 9060, 9080, 9090, 9091, 9200, 9443, 9800, 9981, 12443, 16080, 18091, 18092, 20720, 28017

❯ cat domains.txt | fprobe -p medium/large/xlarge

Skip default probes
If you don't want to probe for HTTP on port 80 or HTTPS on port 443, you can use the -s flag.

❯ cat domains.txt | fprobe -s

Verbose
The verbose output will be format in JSON format with some additional headers, such as Status Code, Content Type, Location.

❯ cat domains.txt | fprobe -v

{"site":"http://google.com","status_code":301,"server":"gws","content_type":"text/html; charset=UTF-8","location":"http://www.google.com/"}
{"site":"https://google.com","status_code":301,"server":"gws","content_type":"text/html; charset=UTF-8","location":"https://www.google.com/"}
