I suspect that you may not get this to work as I doubt that Terminator will accept synthetic events and I don't think that multiple terminal per window model is compatible, but If you want to try the best source is the README.Debian.gz from the debian package. I have included the relevant portion below, but It would probably be much simpler to just use Terminator's grouping option
Super+g: Group all terminals so that any input sent to one of them, goes to all of them. (from the man page)
Clusterssh no longer allows the use of just any Debian terminal
emulator that provides x-terminal-emulator, since a number of them
don't support the XSendEvents resource. By default, clusterssh will
invoke xterm. To change this, create or modify your config file to
contain the line:
terminal = /path/to/my/favorite/terminal-emulator
Note that this terminal emulator must accept the "-xrm" command line
switch to set XTerm.VT100.allowSendEvents:true (or something that does
the same thing). If your terminal emulator provides equivalent
functionality with a different switch, or provides it implicitly, you
can set this with the parameter "terminal_allow_send_events" in the
If you are having trouble getting clusterssh to work with uxterm, you
should either delete the "terminal_allow_send_events" option from
your config file, or update the value to:
Older versions of clusterssh would create the .csshrc file with the
class set to "XTerm" which prevents the uxterm from receiving events.
The terminal emulator must also accept:
System-wide configure changes can be made by editing /etc/csshrc.
