First of all there is pdsh which is essentially a parallel distributed shell which may execute commands on a list of given hosts. However, I find myself in an IPv6 only problem setting. It seems that pdsh is not able to use IPv6, as I am getting error messages:

pdsh -w ^hostnames my_command
pdsh@myhost: gethostbyname("foobar") failed

I also tried to use IPv6 addresses only, which also didn't work. So how do you run a single shell script for administrative purpose (no SGE stuff, or similar) on a bunch of hosts that is IPv6 reachable only?
