If you haven’t used mRemote, I strongly recommend you do. This is a great application that is a “one stop shop” remote server and device management tool. You can manage anything and everything which uses these protocols (RDP, VNC, ICA, SSH, Telnet, RAW, Rlogin and HTTP/S). So basically any UNIX, Linux, Windows server, any network switch or device that you are remotely administering – all through one application. The connections can be easily duplicated, and sorted as well as folders for organization.
All in all, a great tool for managing a mixed environment of OS and devices!
