Linux passive ftp not working problem and solution

Posted by Vivek on Thursday January 4, 07 @6:36 pm

Q. My passive ftp is not working, what can do to fix this problem?

A. Make sure firewall is not blocking your FTP session. If ports are open make sure IPtables is allowing passive ftp. To solve this problem add ip_conntrack_ftp module. Type the following command to load this module:
# modprobe ip_conntrack_ftp

Add this module to your IPtables firewall script:
# firewall
iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
modprobe ip_conntrack
modprobe ip_conntrack_ftp

# Setting default filter policy
iptables -P INPUT DROP
iptables -P OUTPUT ACCEPT
# Rest of rules
