    When FTPing into my box (redhat fc2) there is a long pause at the connecting data channel.

    Running Plesk 7.5.2 and after seaching the forums here I did the follow but still no fix.

    1. Made sure
    UseReverseDNS off
    IdentLookups off
    were in my proftpd.conf

    2. made sure -Rt0 was in my

    3. restarted xintd
    service xinetd restart

    still the same slowness.

    Any help or suggestions would be great.

    Thanks in advance.

    No one has any suggestions??

    I even tried configuring proftpd in standalone instead of through xinetd but its still the same long wait.

    service smtp
    socket_type = stream
    protocol = tcp
    wait = no
    disable = no
    user = root
    instances = UNLIMITED
    server = /var/qmail/bin/tcp-env
    server_args = -Rt0 /var/qmail/bin/relaylock /var/qmail/bin/qmail-smtpd /var/qmail/bin/smtp_auth /var/qmail/bin/true /var/qmail/bin/cmd5checkpw /var/qmail/bin/true

    your smtp_psa file looks just fine ...... hmmm that's what did the trick for me....

    Also remember to do the same for smtps_psa .......

    Anyone out there have any ideas?? I'm stumped :(

    Try updating to 7.5.3, but I doubt that will fix the problem. It is now safe to upgrade to 7.5.3, not the 7.5.4 beta :)

    I tried that but I get an error during the upgrade.

    error: Failed dependencies:
    psa-api-common = 7.5.2 is needed by (installed) psa-api-rpc-7.5.2-rh9.build75050128.10

    How are you upgrading? RPM? or autoinstaller? Is this a VPS?

    I posted this in an earlier thread today:

    Is your firewall limiting any of the ports between 1024-65534 (incoming or outgoing)?

    See the proftpd docs on passive port ranges.


    I believe the 'default' is for it to try to allocate ports:

    PassivePorts 49152 65534

    If it cannot allocate, then it has to do additional processing to get kernel allocated ports to use which could be contributing to a delay.

    I was attempting the autoinstaller, because I am not super familar with the rpm method steps.

    Thanks I think that worked.

    Here is what I did.

    I used the PassivePorts line in my proftpd.conf file and set it to a small range of about 30 starting from 49152
    (since you have to open each port 1 by 1 in plesk firewall.) :(

    Then opened that range in the firewall.

    It seems like it is responding better now. I'll see if the customers stop complaining and then I'll know for sure.
