If these are unix machines then I would use ssh/scp.

Use scp to copy the script to /tmp then run it and collect the output
with ssh (and os.popen/subprocess)

You can set ssh/scp up with keys too.

Number of RAM slots is reasonably hard to obtain.  You might want to
investigate dmidecode for unix which queries the bios.  It gives you
stuff like this showing my machine has 4 slots, with 2x512 MB in.
