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.

Corkscrew tunnels SSH connections through most HTTP and HTTPS proxies. It supports proxy authentication through the HTTP basic authentication scheme with optional TLS to protect credentials.

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.

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.

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.

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.

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.

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

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.

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.

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.

GNU lsh is a free implementation of the SSH version 2 protocol. It is used to create a secure line of communication between two computers, providing shell access to the server system from the client. It provides both the server daemon and the client application, as well as tools for manipulating key files.

DING-LIBS (DING Is Not Glib) are a set of small, useful libraries that the System Security Services Daemon (SSSD) uses and makes available to other projects. They include: libdhash, an implementation of a dynamic hash table which will dynamically resize to achieve optimal storage and access time properties; ini_config, a library for parsing and managing INI files; path_utils, a library to manage UNIX paths and subsets of paths; collection, a generic, hierarchical grouping mechanism for complex data sets; ref_array, a dynamically-growing, reference-counted array; libbasicobjects, a set of fundamental object types for C.

SSSD is a system daemon. Its primary function is to provide access to identity and authentication remote resource through a common framework that can provide caching and offline support to the system. It provides PAM and NSS modules, and in the future will support D-BUS based interfaces for extended user information. It also provides a better database to store local users as well as extended user data.

adcli is a command‐line tool to join a computer to an Active Directory domain. It can also update the machine password and manage user, group and computer accounts for a domain.

This package finds the k nearest neighbours for every point in a given dataset in O(N log N) time using Arya and Mount's ANN library. Provides approximate, exact searches, fixed radius searches, bd and kb trees.

This package provides a tbl_df class that offers better checking and printing capabilities than traditional data frames.

This is a package to provide infrastructure for managing package parameters. Parameters are easy to get in relevant functions within a package, and rrror is thrown if a parameter is missing. Developers are able to register parameters and set their default value in a config file that is part of the package in YAML format, and users are able to override parameters using their own YAML. Users get an exception when trying to override a parameter that was not registered, and can load multiple parameters to the current environment.

This package provides utility functions useful when programming and developing R packages.

This package enables survival analysis in Python, including Kaplan Meier, Nelson Aalen and regression.

Similarity Weighted Nonnegative Embedding (SWNE) is a method for visualizing high dimensional datasets. SWNE uses Nonnegative Matrix Factorization to decompose datasets into latent factors, projects those factors onto 2 dimensions, and embeds samples and key features in 2 dimensions relative to the factors. SWNE can capture both the local and global dataset structure, and allows relevant features to be embedded directly onto the visualization, facilitating interpretation of the data.
