httprobe

Take a list of domains and probe for working http and https servers.

Install

▶ go install github.com/TargetPackage/httprobe@latest

Basic Usage

httprobe accepts line-delimited domains on stdin:

▶ cat recon/example/domains.txt
example.com
example.edu
example.net
▶ cat recon/example/domains.txt | httprobe
http://example.com
http://example.net
http://example.edu
https://example.com
https://example.edu
https://example.net

Flags

Extra Probes

By default httprobe checks for HTTP on port 80 and HTTPS on port 443. You can add additional probes with the -p flag by specifying a protocol and a comma-delimited port list pair:

▶ cat domains.txt | httprobe -p http:81,8080,8081 -p https:8443

If you want to probe some ports on both HTTP and HTTPS, then you can omit the protocol:

▶ cat domains.txt | httprobe -p 1234,4321,8088

You can probe a pre-defined list of ports that are commonly used for HTTP(S) by using the keywords small, large, xlarge, and xxlarge:

▶ cat domains.txt | httprobe -p large
▶ cat domains.txt | httprobe -p https:large,1234 -p http:xlarge

Concurrency

You can set the concurrency level with the -c flag:

▶ cat domains.txt | httprobe -c 50

Timeout

You can change the timeout by using the -t flag and specifying a timeout in milliseconds:

▶ cat domains.txt | httprobe -t 20000

Skipping 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. You'll need to specify the probes you do want using the -p flag:

▶ cat domains.txt | httprobe -s -p https:8443

Prefer HTTPS

Sometimes you don't care about checking HTTP if HTTPS is working. You can do that with the --prefer-https flag:

▶ cat domains.txt | httprobe --prefer-https

Follow redirects

In case you want to apply a filter based on status code, you may also want to follow redirects to determine the final status code:

▶ cat domains.txt | httprobe --follow-redirect

Filter Cloudflare Errors

If you want to ignore hits where the page contains a Cloudflare error indicator:

▶ cat domains.txt | httprobe --filter-cf-errors

Docker

Build the docker container:

▶ docker build -t httprobe .

Run the container, passing the contents of a file into stdin of the process inside the container. -i is required to correctly map stdin into the container and to the httprobe binary.

▶ cat domains.txt | docker run -i httprobe <args>
