Listening on Multiple Ports

To listen for traffic on additional ports launch the Caido CLI with the --ui-listen <address:port> and multiple --proxy-listen <address:port> arguments.

INFO

Specifying different listening ports for the user-interface GraphQL API calls and traffic bypasses Caido's default traffic splitting algorithm.

WARNING

Please note that if you change the listening address to something other than 127.0.0.1, Caido will be accessible from any device on the network, so it is important to consider the security implications of doing so.

For example, to listen for traffic on two ports, enter:

caido-cli --ui-listen 127.0.0.1:8080 --proxy-listen 127.0.0.1:8081 --proxy-listen 127.0.0.1:8082

The user-interface will launch in a browser window at 127.0.0.1:8080.

The browser user-interface.

You can then configure proxy settings to listen for traffic on 127.0.0.1:8081 and 127.0.0.1:8082.
