Changing the Listening Address/Port
By default, Caido listens on the IP address 127.0.0.1
and port 8080
. This means that Caido will only be accessible from the same device it is running on.
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.
Caido CLI
To change the listening address/port with the Caido CLI, launch Caido with the -l <address:port>
