Yes.. csshx seems to work – and point is well taken about multiple sessions. Fortunately, I have only 4 nodes to control.

I have used clusterssh many times. (should be in the ubuntu repository).
It is dependent on xwindows, as it just spawns xterms and copies the input stream to all the windows simultaneously. csshx on the mac works similarly, but with the osx terminal app instead.
It sounds like clusterssh will do what you are looking for.
Be careful how many you do, your screen can get quite cluttered once you get over 10 sessions going.

What I would like is to have the console output from the N ssh sessions return to separate windows..
Pdsh does a nice job of bringing it all back to one place, but it would be nice to have it divided up.. Say you’re doing pdsh to fire off a sequence of apt-get, or ls or something like that which returns multiple lines.. – since each node runs at a different rate, the lines come back randomly interspersed.
$pdsh -w b0[1-4] “ls -al /tmp/*”
$pdsh -w b0[1-4] “echo temppwd | sudo -S apt-get update package”
I happen to be on a Mac, so there are apps like iTerm2 that apparently do this, but I’d like a bit more generic (any *nix)
I see ClusterSSH in a google search, but haven’t tried it yet. Apparently there’s a flavor called csshX for Mac OS X
