I've installed ProFTPD on Debian Wheezy and everything works fine, except it won't start up on boot.
I've tried the following after a lot of Googling:
update-rc.d proftpd defaults
insserv proftpd
ln -s /etc/init.d/proftpd /etc/rc5.d/
Nothing works.
In some setups you have to set
RUN=yes
in/etc/default/proftpd
manually in order run this service at boot.
