Key Takeaway: Sshd is the daemon program for ssh. Sshd and ssh replace rlogin and rsh to provide secure encrypted communications between two untrusted hosts over an insecure network. sshd forks a new daemon for each incoming connection. The forked daemons handle key exchange, encryption, authentication, command execution, and data exchange.
