An SSH server is a software program which uses the Secure Shell protocol to accept connections from remote computers. SFTP / SCP file transfers and remote terminal connections are popular use cases for an SSH server.
NAT passthrough: the ability to connect to the server behind a NAT without configuring the router's port forwarding rules. It offers an advantage when you can't reconfigure the router/firewall (for example in case it is on the Internet service provider's side), but is a serious security risk (unless the traffic is end-to-end encrypted), because ...
An SSH client is a software program which uses the secure shell protocol to connect to a remote computer. This article compares a selection of notable clients. This article compares a selection of notable clients.
It is possible, however, to run it over SSH-1 (and some implementations support this) or other data streams. Running an SFTP server over SSH-1 is not platform-independent as SSH-1 does not support the concept of subsystems. An SFTP client willing to connect to an SSH-1 server needs to know the path to the SFTP server binary on the server side.
Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).
OpenSSH includes the ability to set up a secured channel through which data sent to local, client-side Unix domain sockets or local, client-side TCP ports may be "forwarded" (sent across the secured channel) for routing on the server side; when this forwarding is set up, the server is instructed to send that forwarded data to some socket or TCP ...
SSH operates as a layered protocol suite comprising three principal hierarchical components: the transport layer provides server authentication, confidentiality, and integrity; the user authentication protocol validates the user to the server; and the connection protocol multiplexes the encrypted tunnel into multiple logical communication channels.
The control port is the port used for the dialogue of commands and status updates between client and server. The column "Assigned by IANA" indicates whether the port is listed in the Service Name and Transport Protocol Port Number Registry, which is curated by the Internet Assigned Numbers Authority (IANA).
