You can not execute scripts via ftp on other machines, no matter which OS you are on. For this you should look into setting up SSH. Ftp is just a File Transfer Protocoll and a client named like it, using just that protocoll to simply transfer files, but not for executing remote scripts.

Check if rexec command works for you.

man rexec
