Issue FTP Problem: 425 Unable to build data connection: Connection refused

Boris Ortega

New Pleskian
Since last update I'm ubale to connect to FTP, I have tried everything:

root@host2 /etc/apache2 # telnet localhost 21
Trying ::1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 ProFTPD 1.3.5d Server (ProFTPD) [::1]
USER cygtelsac
331 Password required for cygtelsac
PASS ********
230 User cygtelsac logged in
LIST
425 Unable to build data connection: Connection refused
450 LIST: Connection refused

A working proftpd.conf file would help a lot.
 
Please make sure that FTP data Port 20 is not firewalled.
 
hmm... Could you provide logs from FTP-client (e.g. FileZilla), not from telnet because FTP service does use not only 21/tcp port. That's why error "Unable to build data connection".
