Using httprobe with custom ports — how to format input correctly?

[clarabennettdev]

I want to probe specific ports beyond the default 80/443. The README mentions you can append ports but I'm getting inconsistent results.

For example, if I have:

example.com
test.org

And I want to check ports 8080 and 8443 in addition to the defaults, what's the correct way to do this? Do I need to format my input list differently, or is there a flag for additional ports?

Also curious if there's a way to only check custom ports and skip 80/443 entirely.

You can use the -p flag to add custom ports! Here's how it works:

cat subs.txt | httprobe -p http:8080 -p https:8443

This will check the default ports (80/443) plus your custom ones. The format is protocol:port.

If you want to only check custom ports and skip the defaults, use the -s (skip default) flag:

cat subs.txt | httprobe -s -p http:8080 -p https:8443

You can also combine multiple -p flags:

cat subs.txt | httprobe -p http:8080 -p http:8000 -p https:8443 -p https:4443

One thing to note: the input list should just be clean hostnames (one per line), no protocol prefixes. httprobe handles the protocol/port combinations itself.

The -s flag is super useful when you're specifically hunting for dev servers or non-standard deployments.
