No, leave it to "inetd". Usually Proftpd is launched through Xinetd, so you
don't start it by running "/etc/init.d/proftpd start" but by running
"/etc/init.d/xinetd restart".
The "Socket operation on non-socket" probably happened because it was already
running through Xinetd when you tried to restart it in Standalone mode.
