Belier reaches the final computer through intermediate machines.You can execute commands with any account available on the remote computer.It is possible to switch account on intermediate computers before accessing the final computer.You can open a data tunnel through every host you cross to the final host.Belier generates one script for each final computer to reach.
Belier aims to give a single system administrator a tool to work independently, without requiring to modify the computers he has to cross, just using the current configurations of every machines he has to work with.
