Running Commands On all ACL Machines Simultaneously
To run a command on all the acls, there is a script on tauon: aclexec. It works on top of pssh, try looking at the manpages for pssh if you need more details.
The syntax for aclexec is as follows (you need to be in gods for this to work):
sudo aclexec <command>
If you want to see any output (after the commands have finished), you can pass the -i option to pssh to enable output echoing:
sudo aclexec -i <command>
