    Anyone know why the connection to our ProFTP server (in cPanel) will seem to hang for 10 to 15 seconds for our customers if we have our IPCHAINS firewall enabled? We have port 21 (UDP and TCP open).

    Any ideas?

    Do you have proftpd doing a reverse lookup? I think by default this is the case, try disabling this and see if it works.

    How do you disabled reverse lookup in ProFTP?

    The word 'UseReverseDNS' does not exist in our proftpd.conf. Do I need to add it, if so, like this?:

    UseReverseDNS Off

    I believe that it should exist by default, can't immagine why it's not there. In any case in my proftpd.conf this voice is just under the setting for Anonymous access ...something like this :

    bla bla
    bla bla

    &/Anonymous&


    UseReverseDNS off


    bla bla
    bla bla

    note : between the word UseReverseDNS and the word off there are 16 spaces, don't know if this has any importance, but I'm saying it in case it is important ;) , just trying to help, forgive my ignorance.
