    I had problem with ftp(proftp), take long time to login and almost not login correctly, after searching I found to open port 20 in my firewall)(iptables)
    and its working and working so fast.
    but I am feeling this is not correct and good.
    I already opened port 21:confused:
    i install FC5 (perfect install+ispconfig)
    any recommendation?
    and what is better ftp active mode or passive ?

    many thanks

    Opening port 20 is fine if you want to use active FTP. Please have a look here for a detailed exolanation:


    I'am not sure if one can say active or passive FTP is better. One some internet connections I get better results with passive FTP, on others active FTP is more reliable and faster.

    hi till
    thanks for good information, I solved the problem by adding :
    modprobe ip_conntrack_ftp
    modprobe ip_nat_ftp

    to my iptables and its work great right now(local/outside) pasive and active
    one more question :
    what about open DNS?
    how to close it :p ?
    note I am running the dns in the same server dns1 an ddns2 :rolleyes:
