How To Fix pt-websocket-server: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu pt-websocket-server is provided by pt-websocket package.

pt-websocket is:

Pluggable transports are tools that transform a stream of application traffic into a different format on the network. This helps to bypass network-level censorship.

This package contains a server transport plugin that accepts connections transformed to look like the websocket protocol. This is typically used to enhance systems like Tor, to provide service even to censored users.

See flashproxy-client for a corresponding client transport plugin, meant for users to bypass censorship, that is compatible with the websocket protocol that this package expects.

(The source package also contains a websocket-client transport plugin, but this is just a demo that is less effective than flashproxy-client, and not meant to be used in real situations.)

sudo apt-get -y install pt-websocket

This command might take some time to finish depending on your machine internet connection.
