ProFTP(D) – listen on single ip

I don’t use ftp, but wordpress comes with this nice feature to upgrade plugins automatically from the web admin interface that needs ftp.

the problem is I don’t want to enable the ftp service and make it available to the rest of the world just for that.

So I needs the following two options in proftpd.conf:

SocketBindTight on

Now restart proftpd and you’re done.
