sshuttle is an SSH tunneling proxy and user-space network router that forwards local network traffic to a remote network via an encrypted SSH connection. It serves as an alternative to traditional VPN installations for routing traffic and accessing private remote resources.
The project functions by redirecting network traffic through an SSH tunnel without requiring administrative privileges on the remote server. It utilizes a user-space TCP/IP stack to process packets, allowing it to operate without kernel-level administrative access.
Its capabilities cover remote network access, secure remote administration, and transparent proxying to reach internal servers or services.
