Powerful connection management is compatible with a variety of connection types. Using RDP, VNC, SSH-based terminals, S/FTP, or web-based interfaces? No worries, Royal TS got you covered! Built-in credential management. Safe team-sharing features. Share a list of connections, without sharing your personal credentials. Command tasks and key sequence tasks make it easy to quickly automate repetitive tasks. SSH-based tunneling (secure gateway) support is tightly integrated into Royal TS. Dynamic Folders allow you to dynamically import data from external sources. You can assign a credential to connections by specifying the name of the credential. This allows you to share a document containing only connections while your personal credential is stored in a private document, protected by your password. Royal TS can handle documents opened by multiple users at the same time and allows you to synchronize document changes without the need for a SQL database back-end!

PuTTY is a free implementation of SSH and Telnet for Windows and Unix platforms, along with an xterm terminal emulator. PuTTY is a client program for the SSH, Telnet, Rlogin, and SUPDUP network protocols. These protocols are all used to run a remote session on a computer, over a network. PuTTY implements the client end of that session, the end at which the session is displayed, rather than the end at which it runs. In really simple terms, you run PuTTY on a Windows machine, and tell it to connect to (for example) a Unix machine. PuTTY opens a window. Then, anything you type into that window is sent straight to the Unix machine, and everything the Unix machine sends back is displayed in the window. So you can work on the Unix machine as if you were sitting at its console, while actually sitting somewhere else. All of PuTTY's settings can be saved in named session profiles. You can also change the default settings that are used for new sessions.
