    I rarely use proftpd but, it has been working fine for years on my ISPConfig2 box.
    Today I tried to connect and the connection times out.

    Here are results in /var/log/messages
    Code:
    Apr 22 00:02:05 mbshop2 proftpd[18652]: mbshop2.peachparts.com (::ffff:127.0.0.1[::ffff:127.0.0.1]) - FTP session opened.

    proftpd is running.

    Here's proftpd.conf:

    More info...

    I seem to be getting segfaults:
    Code:
    Apr 22 11:15:22 mbshop2 kernel: php[13394]: segfault at 00007fff3a6feff8 rip 0000000000670b30 rsp 00007fff3a6ff028 error 6
    Apr 22 11:17:33 mbshop2 kernel: php[14160]: segfault at 00007fffacfcbfd8 rip 000000000068f1eb rsp 00007fffacfcc028 error 6
    Possibly a hardware problem?

    In addition, I had to turn off my dkim and dk milters because they were unable to connect:
    Code:
    NOQUEUE: milter-reject: EHLO from localhost.localdomain[127.0.0.1]: 451 4.7.1 Service unavailable - try again later; proto=SMTP
     NOQUEUE: milter-reject: MAIL from localhost.localdomain[127.0.0.1]: 451 4.7.1 Service unavailable - try again later; proto=ESMTP helo=<localhost>
    I think all of these problems are related somehow.

    Port 21 not open?

    I just ran a port scan of my server and port-21 is showing closed even though it shows open in ISPConfig2.

    Here's the output from iptables -L

    ISPConfig not updating firewall

    Ok, if i stop the Bastille firewall ( /etc/init.d/bastille-firewall stop ) I can connect via FTP.
    The weird thing is that ISPConfig still shows the firewall "Online" even though it is stopped.
    When I restart the firewall ( /etc/init.d/bastille-firewall start) I cannot connect via FTP. Even though ISPConfig shows that FTP Port-21 is open.

    The problem appears to be that ISPConfig is not changing the status of the firewall. I can turn ports on or off and even turn the firewall off in ISPConfig and nothing really changes even though ISPConfig indicates that it did.

    ISPConfig not updating firewall

    I ran more tests and found that changing a port from active to not active in ISPConfig does indeed change the status in the ispconfigdb isp_firewall dienst_aktiv from ja to nein. So the MySQL updates are working.

    The problem is that the Bastille firewall never get updated. No iptables rules are being changed. If I run iptables -L before making a firewall change in ISPConfig and then again after the change, I get exactly the same result. No iptables change.

    How to fix???

    Do you see your changes in the Bastille configuration file /etc/Bastille/bastille-firewall.cfg?

    No.
    When I open Port-21 in ISPConfig, it never gets added to this line:
    Code:
    TCP_PUBLIC_SERVICES="22 25 53 80 81 110 443 587"

    Segmentation fault

    Falko-
    Running writeconf.php results in a segmentation fault:
    Code:
    [[email protected] ~]# /root/ispconfig/php/php -q /root/ispconfig/scripts/writeconf.php
    start
    Segmentation fault
    ispconfig.log only shows these entries:
    Code:

    The segfault appears to happen at this step in writeconf.php:
    Code:
    //Firewall-Konfiguration
    $isp_web->make_firewall();

    Fixed!

    A big thanks to crypted for his help!

    The solution was as follows:

    1) Make sure the permissions are correct on the folders bind uses:
    Code:
    chmod 755 /var/named/
    chmod 775 /var/named/chroot/
    chmod 775 /var/named/chroot/var/
    chmod 775 /var/named/chroot/var/named/
    chmod 775 /var/named/chroot/var/run/
    chmod 777 /var/named/chroot/var/run/named/
    cd /var/named/chroot/var/named/
    ln -s ../../ chroot
    2) Check the Server Settings in ISPConfig
    Go to Management > Server > Settings
    Click on the DNS tab
    These settings must be as follows:
    Code:
    named.conf: /var/named/chroot/etc/named.conf
    Zonefiles Dir.: /var/named/chroot/var/named
    Life is good again! [​IMG]
