According to Wikipedia:
- Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. Its most notable applications are remote login and command-line execution.
Examples of services that can use SSH are Git, rsync and X11 forwarding. Services that always use SSH are SCP and SFTP.
An SSH server, by default, listens on the standard TCP port 22. An SSH client program is typically used for establishing connections to an sshd daemon accepting remote connections. Both are commonly present on most modern operating systems, including macOS, GNU/Linux, Solaris and OpenVMS. Proprietary, freeware and open source versions of various levels of complexity and completeness exist.
Software
- Dropbear — Lightweight SSH server. The command-line ssh client is named dbclient(1).
- OpenSSH — Premier connectivity tool for remote login with the SSH protocol
Server only
- TinySSH — A minimalistic SSH server which implements only a subset of SSHv2 features; glibc as its single dependency.
Client only
- PuTTY — A terminal integrated SSH/Telnet client
Securing
