FTP: Data Socket Error: Connection failed [iptables]

Dupa un спрете & Започнете the iptables, am reusit performanta sa pierd toate conexiunile la ftp:

root@server [~]# service iptables stop 
Flushing firewall rules:                                   [  OK  ] 
Setting chains to policy ACCEPT: mangle filter             [  OK  ] 
Unloading iptables modules:                                [  OK  ] 
root@server [~]# service iptables start 
Flushing firewall rules:                                   [  OK  ] 
Setting chains to policy ACCEPT: filter                    [  OK  ] 
Unloading iptables modules:                                [  OK  ] 
Applying iptables firewall rules:                          [  OK  ] 
Loading additional iptables modules: ip_conntrack_netbios_n[  OK  ]

Consecinta: [R] Data Socket Error: Connection failed [FTP] входящо / / изходящи, desi in server aparea ca sunt logat, nu aveam acces la nimic.

Решаване:

root@server [~]# iptables -A INPUT -p tcp --dport 21 -j ACCEPT 
root@server [~]# modprobe ip_conntrack_ftp

“/ /” is your current location ;-)
