2. Linux Tips # Pure FTP fix for “failed to retrieve directory listing”.

I was setting up pure-ftpd on a system that needed FTP access for users. The users were using FileZilla. For firewall on the server (running RHEL5), I was using iptables. Was having a difficult time getting FTP with TLS to connect and when I was able to get it to connect I would get the error: “failed to retrieve directory listing”.

Error: Connection timed out
Error: Failed to retrieve directory listing

Here is the fix:

# cat /proc/sys/net/ipv4/ip_local_port_range

32768      61000

Make sure ports used do not fall within that range (used by the system). So pick 10000 to 20000, for example.

# iptables -I INPUT 2 -p tcp –dport 10000:20000 -j ACCEPT

# iptables -I OUTPUT 2 -p tcp –sport 10000:20000 -j ACCEPT

Also need port 21 (port 20 was not needed):

# iptables -I INPUT 2 -p tcp –dport 21 -j ACCEPT

# iptables -I OUTPUT 2 -p tcp –sport 21 -j ACCEPT

Save your iptables of course and then restart:

iptables-save > /etc/sysconfig/iptables

service iptables restart

Then in pure-ftpd, go to conf file (/etc/pure-ftpd.conf and set the following line:

PassivePortRange          10000 20000

service pure-ftpd restart
