    I installed ISPConfig in November 2006 (Mandrake 2006 - perfect setup).
    Well - some mail and DNS related issues but this has been solved manually ;-)

    Then I decided to install a CRON-job to look for updates automatically....and here began the trouble: I cannot login into FTP more (neither via ISPConfig-Admin nor with a FTP-Client).
    It has something to do with the "auto-update" (I have it disabled now).
    Well, it looks like if I have to downgrade the ProFTP.

    My question is: HOW to downgrade without to break the ISPConfig - configuration ?

    I think its not nescessary to downgrade proftpd as all proftpd versions should be compatible with ISPConfig.

    Please have a look if your last proftpd update has replaced the proftpd.conf file and left a copy of the old configuration in the same directory which you can compare to the new config.

    Please post the output of:

    netstat -tap | grep ftp


    ps aux | grep ftp

    Hi Till,

    thanks for your answer.
    The outputs are:
    --------------- cut -----------------
    > netstat -tap | grep ftp
    tcp 0 0 *:ftp *:* LISTEN 29701/proftpd: (acc


    > ps aux | grep ftp
    nobody 29701 0.0 0.5 5660 2580 ? Ss Apr08 0:00 proftpd: (accepting connections)
    root 11928 0.0 0.2 2204 1024 ? R 09:05 0:00 sh -c (ps aux | grep ftp) 2>&1
    root 11929 0.0 0.2 2204 1040 ? R 09:05 0:00 sh -c (ps aux | grep ftp) 2>&1

    ------------- cut ------------------

    It seems, that the command netstat -tap | grep ftp outputs incomplete data ..

    That's normal.
    FTP seems to be running.
    Is FTP allowed in the firewall? What's the output of
    iptables -L
    ? Are there any errors in your logs?

    Output of Iptables -L
    --------------------- cut ----------------------
    > iptables -L
    Chain INPUT (policy ACCEPT)
    target prot opt source destination

    Chain FORWARD (policy ACCEPT)
    target prot opt source destination

    Chain OUTPUT (policy ACCEPT)
    target prot opt source destination
    ------------------------ cut ------------------------------

    and yes. ftp is allowed in the firewall ... and it was running before very well, but now I cannot more access FTP neither outside nor locally (and this has something to do with the auto-update..).

    Sometimes I have a strange log in syslog:
    -------------- cut --------------------
    Apr 10 10:30:00 mail proftpd[8538]: mail.myname.net (mail.myname.net []) - FTP session opened.
    Apr 10 10:30:00 mail proftpd[8538]: mail.myname.net (mail.myname.net []) - invalid CommandBufferSize size (0) given, resetting to default buffer size (512)

    What's in /etc/proftpd.conf?

    Hi Falko,

    here is the output of /etc/proftpd.conf

    The configuration looks ok, so it must be a problem with ProFTPd itself. :(

    ..Hi falko,

    ..yes.. I think so. I will guard the proftp.conf and downgrade to the original version of the Mandriva 2006 CD ..

    A cue for you - the log cheated

    I've just experienced similar thing as you.

    I failed to run "urpmi" with message after updated proftpd.conf:
    But I overlooked the "access denied" and went to check log message, which showed the same strange triplet as you:

    I started snort to check the packets and found it's indeed some "Permission denied" condition.

    So I suggest that you check again the error message in your ftp client. It's quite probable an access permission problem.

    FTP - the solucion ?

    Well, as I wrote before I deleted the FTP and installed it again (of course with the config-fies backed up).

    AND YES .. I could access the sites with the built-in FTP-access in the administration-panel. BUT .. ftp-access via Kbear didnt run (OS Linux).

    I gave it a try and installed GFTP .. and YESSS .. it runs ok.

    I did not test it with windows-FTP-clients .. but if there is a connecting-problem I think its worth to try another FTP-client.
