This is a mind note, cause i always forgot the command to create a dinamic port forwarding through ssh. Suppose you want to navigate the web with your browser but you want that the browser connection is made by other machine that has sshd running. So you can access web pages as if from the other machine.
You need to create a connection to the sshd server with the parameter -D and the port number where the local machine will listen to forward the connections. Example:
command>ssh myuser@sshdserver -D 8080
Now you have to configure the web browser to use SOCK Host: localhost Port:8080
In windows you can use putty, and you have to configure
Option: Source Port = 8080
