The way to do this is to set php up on the remote server to have a web
page run that script.

e.g. on the machine2 that runs a script have a php file that does this

echo (exec('script.sh'));

and then on machine1 simply use curl to point not at the script, but at
the URL of the php file that actually runs that script.

Ineptocracy

(in-ep-toc’-ra-cy) – a system of government where the least capable to
lead are elected by the least capable of producing, and where the
members of society least likely to sustain themselves or succeed, are
rewarded with goods and services paid for by the confiscated wealth of a
diminishing number of producers.
