VSFTP Problems with Firewall

I was able to establish a connection, but directory listing failed. With a firewall (20,21) it is necessary to enable ip_conntrack_ftp. The following should work ...

$ modprobe -v ip_conntrack_ftp insmod /lib/modules/2.6.9-5.ELsmp/kernel/net/ipv4/netfilter/ip_conntrack_ftp.ko $vi /etc/sysconfig/iptables_config IPTABLES_MODULES="ip_conntrack_ftp"
