i just did
apt-get install proftpd
then as root i unchecked the proftpd service at startup, so i can just
proftpd -n
whenever i want to (because i only run it sometimes...when i need it). however i did not make many changes to my proftpd.conf file (just made it type=standalone)... i didn't change any permissions or anything... i figure this is secure enough for me since i only start it when i want to move some files and then end it when im finished... is this ok?
