Classically, if you can connect to a FTP server but you cannot do a 'dir', your command channel (port 21 classically) is fine but you're having problems with the <a href="http://www.allaboutjake.com/network/linksys/ftp/">data channel</a> (port 20). That your data channel hangs unless people go passive suggests it could be a firewall/networking issue.<br><br>
<i>Update:</i> As an example of the kinds of issues FTP generates, you cannot pass FTP traffic through an [wp://iptables] filter unless you turn on <a href="http://www.cyberciti.biz/faq/iptables-open-ftp-port-21/">ftp connection tracking</a>.<br><br>
