Net::SSH is a pure-Ruby implementation of the SSH2 client protocol. It supports the following features: - User authentication via explicit username/password, or using a public-key/private-key pair. - Port forwarding, both from the local host to a remote computer via the remote host, and from the remote host to the local host. - Execute processes on the remote machine, both interactively and non-interactively ("batch").
