SSH (Secure Shell)
Description
SSH is a protocol for establishing an encrypted tunnel between two network hosts that can be used to provide secure network services, notably:
- secure login (by means of the
sshcommand), and - secure file transfer (by means of the
scpandsftpcommands), and - forwarding of X11 (X Window System) connections.
The most popular Open Source implementation of the SSH protocol is OpenSSH.
