how to make multiple port search on shodan

Question

First of all I'm sorry if this question should be on another forum but I had some difficulties to find out where to ask this and from the site I'm not getting any reply.

Can you tell me how can I search for devices which have 2 or more specific ports open simultaneously because I'm only able to search one at a time?

Answer 1

You can use use search.censys.io to do something like this:

services.port: 17 and services.port: 21

And Results

Alternatively if you are looking for either port 17 or port 21 you can use a set like this:

services.port: {17, 21}

Or Results
