UniTTY is a multi-faceted client that does much more than just standard SSH. This client provides the network administrator with the ability to connect to systems using SSH, SFTP, Telnet, Secure VNC and also provides sophisticated identity management facilities that help to cut down on repeated and unnecessary password entry.
