Dupa un stop & start ที่ 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] incoming - outgoing, desi in server aparea ca sunt logat, nu aveam acces la nimic.
Rezolvare-
root@server [~]# iptables -A INPUT -p tcp --dport 21 -j ACCEPT
root@server [~]# modprobe ip_conntrack_ftp“-” is your current location ;-)
