ClusterSSH is a tool to manage simultaneous interactive sessions across multiple SSH-accessible hosts. It opens one master terminal and many child terminal windows (or tabs), sending the same keystrokes to all clients while allowing isolated input per host. This is useful when orchestrating repetitive tasks—such as rolling updates or diagnosing distributed systems—without copying and pasting into each window.
ClusterSSH controls a number of xterm windows via a single graphical console window to allow commands to be interactively run on multiple servers over an ssh connection.
