    Ports open even though they should be closed

    Hey guys,

    I don't understand whats going on with my rootserver...
    I have reset iptables and just opened the port for ssh.
    Now suddenly over night I see that there are a various of ports open:
    21,80, 135, 139, 445, 3128

    Could it be that vsftpd for example put rules in automatically to allow input on port 21?

    I also tried disabling iptables with this command:

    Code:
    # iptables -X
    # iptables -t nat -F
    # iptables -t nat -X
    # iptables -t mangle -F
    # iptables -t mangle -X
    # iptables -P INPUT ACCEPT
    # iptables -P FORWARD ACCEPT
    # iptables -P OUTPUT ACCEPT
    after this i did a port scan with shields up! but still there seem to be rules I can not change. Most ports are still closed and the ones mentioned above are open...

    I experimented with firestarter and ufw but uninstalled both... could it be that they still control the firewall?

    services i have installed on my root server are ftp, openvpn, apache and vnc
