KeyBox is a Web-based SSH console for executing commands and managing multiple systems simultaneously. It allows you to share terminal commands and upload files to all your systems. Once the sessions have been opened you can select a single system or any combination on which to run your commands. Also, additional system administrators can be added and their terminal sessions and history can be audited.
PAC provides a GUI to configure SSH and Telnet connections, including usernames, passwords, EXPECT regular expressions, and macros. It is similar in function to SecureCRT or Putty. It is intended for people who connect to many servers through SSH. It can automate logins and command executions.
nassh-relay implements a relay server used with the Secure Shell (hterm) plugin for the Chromium Web browser. It tunnels ssh traffic through an HTTP xhr or websockets connection. It could be used as a gateway to route traffic to an internal network (it supports authentication on the HTTP endpoint) or simply as an ssh-over-HTTP proxy.
Window Switch is a tool that allows you to move applications between networked computers. The windows appear where you need them, as they were. You no longer need to save and send documents to move them around; simply move the view of the application to the machine where you need it.
skd is a tool for the simple distribution of SSH keys in a growing environment. It allow you to create hosts, group them, and link that group a group of users with keys to easily distribute all affected keys. skd generates a DSA or RSA keypair, which is saved to its database and used as the authentication source for skd itself. This keypair can (and should be) additionally be encrypted using a passphrase. This allows you to simply add a user with their key and press one button to grant (and revoke!) the user's access to all needed hosts.
The X2Go Client allows you to connect to and control a remote machine running the X2Go Server. You can simulate a complete desktop session or run individual remote applications as if they were running on your local machine. The protocol is secure (via SSH) and very responsive, even over a very slow connection.
