The forwarding of data is bidirectional, meaning that any return communication is itself forwarded back to the client-side in the same manner; this is known as an "SSH tunnel", [23] and it can be used to multiplex additional TCP connections over a single SSH connection since 2004, [24] to conceal connections, to encrypt protocols that are ...
A single SSH connection can be multiplexed into multiple logical channels simultaneously, each transferring data bidirectionally. Channel requests are used to relay out-of-band channel-specific data, such as the changed size of a terminal window, or the exit code of a server-side process.
This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
Web-based SSH clients are applications that allow users to access Secure Shell (SSH) servers through a web browser. They consist of two main parts: a client-side component, which is typically implemented using JavaScript and dynamic HTML , and a server-side or web application component, which is typically implemented on an application server .
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.
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.
In computer networking, port knocking is a method of externally opening ports on a firewall by generating a connection attempt on a set of prespecified closed ports. Once a correct sequence of connection attempts is received, the firewall rules are dynamically modified to allow the host which sent the connection attempts to connect over specific port(s).
Port forwarding via NAT router. In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.
