Squirrel is a high level imperative, object-oriented programming language, designed to be a light-weight scripting language that fits in the size, memory bandwidth, and real-time requirements of applications like video games.

AsyncSSH is a Python package which provides an asynchronous client and server implementation of the SSHv2 protocol on top of the Python 3.6+ asyncio framework.

Guile-SSH is a library that provides access to the SSH protocol for programs written in GNU Guile interpreter. It is a wrapper to the underlying libssh library.

Mosh is a remote terminal application that allows client roaming, supports intermittent connectivity, and provides intelligent local echo and line editing of user keystrokes. It's a replacement for SSH that's more robust and responsive, especially over Wi-Fi, cellular, and long-distance links.

codex11-ssh-askpass is an X11-based pass-phrase dialog for use with OpenSSH.

The SSH2 protocol implemented in OpenSSH is standardised by the IETF secsh working group and is specified in several RFCs and drafts. It is composed of three layered components:

The transport layer provides algorithm negotiation and a key exchange. The key exchange includes server authentication and results in a cryptographically secured connection: it provides integrity, confidentiality and optional compression.

The user authentication layer uses the established connection and relies on the services provided by the transport layer. It provides several mechanisms for user authentication. These include traditional password authentication as well as public-key or host-based authentication mechanisms.

The connection layer multiplexes many different concurrent channels over the authenticated connection and allows tunneling of login sessions and TCP-forwarding. It provides a flow control service for these channels. Additionally, various channel-specific options can be negotiated.

mock-ssh-server packs a Python context manager that implements an SSH server for testing purposes. It is built on top of paramiko, so it does not need OpenSSH binaries to be installed.

Guile-SSH is a library that provides access to the SSH protocol for programs written in GNU Guile interpreter. It is a wrapper to the underlying libssh library.

Liboop is a low-level event loop management library for POSIX-based operating systems. It supports the development of modular, multiplexed applications which may respond to events from several sources. It replaces the "select() loop" and allows the registration of event handlers for file and network I/O, timers and signals. Since processes use these mechanisms for almost all external communication, liboop can be used as the basis for almost any application.

HPN-SSH is a series of modifications to OpenSSH, the predominant implementation of the ssh protocol. It was originally developed to address performance issues when using ssh on high speed long distance networks.

Pdsh is a an efficient, multithreaded remote shell client which executes commands on multiple remote hosts in parallel. Pdsh implements dynamically loadable modules for extended functionality such as new remote shell services and remote host selection.

libssh2 is a library intended to allow software developers access to the SSH-2 protocol in an easy-to-use self-contained package. It can be built into an application to perform many different tasks when communicating with a server that supports the SSH-2 protocol.

Endlessh is an SSH tarpit that very slowly sends an endless, random SSH banner. It keeps SSH clients locked up for hours or even days at a time. The purpose is to put your real SSH server on another port and then let the script kiddies get stuck in this tarpit instead of bothering a real server.

Since the tarpit is in the banner before any cryptographic exchange occurs, this program doesn't depend on any cryptographic libraries. It's a simple, single-threaded, standalone C program. It uses poll() to trap multiple clients at a time.

sshpass is a tool for non-interactively performing password authentication with SSH's so-called interactive keyboard password authentication.

This package provides a web application to be used as an SSH client.

Features:

• SSH password authentication supported, including empty password.

• SSH public-key authentication supported, including DSA RSA ECDSA Ed25519 keys.

• Encrypted keys supported.

• Two-Factor Authentication (time-based one-time password) supported.

• Fullscreen terminal supported.

• Terminal window resizable.

• Auto detect the ssh server's default encoding.

• Modern browsers are supported.

Dropbear is a relatively small SSH server and client. It runs on a variety of POSIX-based platforms. Dropbear is particularly useful for embedded systems, such as wireless routers.

hss is an interactive SSH client for multiple servers. Commands are executed on all servers in parallel. Execution on one server does not need to wait for that on another server to finish before starting. One can run a command on hundreds of servers at the same time, with almost the same experience as a local Bash shell.

It supports:

• interactive input: based on GNU readline.

• history: responding to the C-r key.

• auto-completion: TAB-completion from remote servers for commands and file names.

ClusterShell is an event-driven Python framework, designed to run local or distant commands in parallel on server farms or on large GNU/Linux clusters. It will take care of common issues encountered on HPC clusters, such as operating on groups of nodes, running distributed commands using optimized execution algorithms, as well as gathering results and merging identical outputs, or retrieving return codes. ClusterShell takes advantage of existing remote shell facilities such as SSH.

libssh is a C library implementing the SSHv2 and SSHv1 protocol for client and server implementations. With libssh, you can remotely execute programs, transfer files, and use a secure and transparent tunnel for your remote applications.

This package provides an implementation of fsspec for the SFTP protocol using asyncssh, with the following features:

• A complete implementation of the fsspec protocol through SFTP

• Supports features outside of the SFTP

• Quite fast

• Builtin Channel Management

• Async

autossh is a program to start a copy of ssh and monitor it, restarting it as necessary should it die or stop passing traffic.
