>Description:
When compile proftpd-1.3.3c_1 with IPv6 support from ports, looks like it can't accure correct IPv6 adresses:
### proftpd -n -d9 ###

Sockstat shows proftpd is listening 21 port for v4 & v6 sockets, but FTP clients can't connect server.
>How-To-Repeat:
Compile proftpd-1.3.3c_1 with IPv6 support from ports, try to connect.
No matter what auth backend you are using.
>Fix:
Temporary solution: turn of IPv6 support at compilation.
