2. suSSHi Architecture

suSSHi functions as a so-called non-transparent proxy between an SSH client and an SSH server, i.e. the servers are protected by suSSHi by preventing direct access, e.g. by a network or host-based firewall or a corresponding host configuration.

For better understanding, the following diagram illustrates the individual components and their relationships:

Next, we will briefly discuss the components and their roles.
