Hello, I am setting up ProFTPd daemon (from EPEL repository) under CentOS 5.2 and I need encrypted connection. Daemon is configured perfectly, there is no problem - if iptables is off connection is smoothly established, but when iptables is on, connection in FTP client ends on command LIST without response. Last command with response (positive) is PASV. Thank you for your replies Martin Šťastný
