Tunneling: Unlike most traditional, application based SSH clients, web-based SSH clients are unable to tunnel ("forward") TCP traffic. For example, running an X session over a web-based SSH session is not possible. However, the lack of ability is caused by implementation issues, and not inherent in some way.
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.
SecureCRT is a commercial SSH and Telnet client and terminal emulator by VanDyke Software. Originally a Windows product, VanDyke later added a Mac OS X version in 2010 with release v6.6 [ 3 ] [ 4 ] and a Linux version in 2011 with release v6.7.
Rsync is a tool for creating backups in Linux systems. It supports backing up local folders, SSH tunneling, [4] delta-only synchronization, and so on. Grsync adds the ability to use such purposes with a graphical user interface, without rsync's need to learn a complex set of command-line arguments.
Tunneling a TCP-encapsulating payload (such as PPP) over a TCP-based connection (such as SSH's port forwarding) is known as "TCP-over-TCP", and doing so can induce a dramatic loss in transmission performance due to the TCP meltdown problem, [26] [27] which is why virtual private network software may instead use for the tunnel connection a ...
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.
A typical configuration is a hardened Unix (or Unix-like) machine configured with SSH and a local firewall. An administrator connects to a target machine in the DMZ by making an SSH connection from the administrator's personal computer to the jump server and then using SSH forwarding to access the target machine.
Stunnel is an open-source multi-platform application used to provide a universal TLS/SSL tunneling service. Stunnel is used to provide secure encrypted connections for clients or servers that do not speak TLS or SSL natively. [4] It runs on a variety of operating systems, [5] including most Unix-like operating systems and Windows.
