This might be a better solution for your problem:
parallel -j0 w4it-for-port-open {} 22\; echo {}\;echo :::
example.com example.net | parallel -r --tty ssh
See http://ole.tange.dk/projekter/my_software/w4it-for-port-open
That will wait for port 22 to open on any of the machines and then ssh
to that machine.
