whatportis

It's a common task to search the default port number of a service. Some ports are available in the /etc/services file, but the list is not complete and this solution is not portable.

Whatportis is a simple tool that downloads the Iana.org database and uses it to explore the official list of ports.

Usage

Whatportis allows you to find what port is associated with a service:

$ whatportis redis
+-------+------+----------+---------------------------------------+
| Name  | Port | Protocol | Description                           |
+-------+------+----------+---------------------------------------+
| redis | 6379 |   tcp    | An advanced key-value cache and store |
+-------+------+----------+---------------------------------------+

Or, conversely, what service is associated with a port number:

$ whatportis 5432
+------------+------+----------+---------------------+
| Name       | Port | Protocol | Description         |
+------------+------+----------+---------------------+
| postgresql | 5432 | tcp, udp | PostgreSQL Database |
+------------+------+----------+---------------------+

You can also search a pattern without knowing the exact name by adding the --like option:

$ whatportis mysql --like
+----------------+-------+----------+-----------------------------------+
| Name           |  Port | Protocol | Description                       |
+----------------+-------+----------+-----------------------------------+
| mysql-cluster  |  1186 | tcp, udp | MySQL Cluster Manager             |
| mysql-cm-agent |  1862 | tcp, udp | MySQL Cluster Manager Agent       |
| mysql-im       |  2273 | tcp, udp | MySQL Instance Manager            |
| mysql          |  3306 | tcp, udp | MySQL                             |
| mysql-proxy    |  6446 | tcp, udp | MySQL Proxy                       |
| mysqlx         | 33060 |   tcp    | MySQL Database Extended Interface |
+----------------+-------+----------+-----------------------------------+

Installation

$ pip install whatportis

Database Sync

Whatportis uses a local JSON file (~/.whatportis_db.json) to explore the list of ports. The first usage will create it for you, then you can use the --update option to synchronize it :

$ whatportis --update
Previous database will be updated, do you want to continue? [y/N]: y

Populating database...
14145 ports imported.

JSON output

You can display the results as JSON, using the --json option :

$ whatportis 5432 --json
[
    {
        "name": "postgresql",
        "port": "5432",
        "protocol": "tcp, udp",
        "description": "PostgreSQL Database"
    }
]

REST API

Whatportis can also be started as a RESTful API server. This feature is not enabled by default, you must install an extra package :

$ pip install whatportis[server]
$ whatportis --server localhost 8080
 * Serving Flask app "whatportis.server" (lazy loading)
 * Environment: prod
 * Debug mode: off
 * Running on http://127.0.0.1:8080/ (Press CTRL+C to quit)

The endpoints are /ports for the whole list (can be long) and /ports/<search> to search a specific port :

$ curl http://127.0.0.1:8080/ports/3306
{"ports":[{"description":"MySQL","name":"mysql","port":"3306","protocol":"tcp, udp"}]}

$ curl http://localhost:8080/ports/redis
{"ports":[{"description":"An advanced key-value cache and store","name":"redis","port":"6379","protocol":"tcp"}]}
