Your shell on remote host is not interactive.
So you can't interact with your program.


On localhost:

$ echo $-
himBH
 ^
 +--- interactive

$ ssh some.host.net 'echo $-'
hBc - noninteractive (there isn't `i')

And it's better to use -s instead of -run:

ssh node0 erl -setcookie cookie -name node -pa $FATHOM/lib -s master checkin
