[nzlug] FTP problem

[anru chen]

finally found what problem was, it was caused by firewall rules.

seems like firefox ftp client implementation is different than my
debain command line
ftp client which probably a BSD style ftp client.

the problem is , ftp has a feature called Passive FTP, we need to
allow it so some ftp clients will connect to FTP server without
problem.

the firewall rule as below:

iptables -A INPUT -i eth0 -p tcp -s any/0 --sport 1024:65535 --dport
1024:65535 -j ACCEPT

so to enable passive FTP, we must allow ftp server to listen on the
unprivileged port.

regards,

anru
