Konsole SSH Multiplexer is a very simple but efficient script, that runs Konsole and starts a number of sessions, each with an SSH connection attached to it.
Additionally the first Session serves as a command multiplexer as every command you enter there is fanned out to the other sessions.
Configuration is basic and straight forward:
Edit the variables located at the top of the script. The example setting would start 8 SSH sessions to servers called project-app-, project-db- and project-web- + 1 command multiplexer session.
SERVERS=([app]=4 [db]=2 [web]=2)
