is "Pythonic Ubiquitous SSH" - a command line wrapper script for
sending commands to multiple machines in parallel, i.e. in *real time*,
with options for controlling the degree of parallelism, timeouts, and
node selections. At present, PuSSH is composed of two Python modules,
one of which is called explicitly by the other, but this "construct"
may change in future versions. PuSSH was designed for usage on networks
/ machine farms with lots, or multiple hosts (or indeed over the entire
internet, for that matter), ideally wherein SSH is configured with
Kerberos or RSA/DSA keys in such a way as to avoid any password
authentication. Using PUSSH, you can send the same command via SSH to a
range of machines of practically any size, and IN PARALLEL - if the
abovementioned conditions for SSH password authentication are met. If
not, then some nifty capabilities are also on offer for purely
sequential command execution on your target machines.
Haven't played with this, but it definitely sounds both interesting and useful.
