Applicable to:

  • Plesk for Linux

Symptoms

  • Unable to connect to Plesk server over FTP with the following error is shown in an FTP client:

    CONFIG_TEXT: Error: Could not connect to server

  • The following error is found in the file /var/log/messages (/var/log/syslog on Debian and Ubuntu):

    CONFIG_TEXT: FAIL: ftp per_source_limit from=203.0.113.2

Cause

Connection limit per IP address is exceeded.

Resolution

  1. Connect to the server using SSH.

  2. Edit the configuration file /etc/xinetd.d/ftp_psa in the following way:

    • Before the change:

      CONFIG_TEXT: service ftp
      {
      flags = IPv6
      disable = no
      socket_type = stream
      protocol = tcp
      wait = no
      user = root
      instances = UNLIMITED
      server = /usr/sbin/in.proftpd
      server_args = -c /etc/proftpd.conf -S 0.0.0.0
      }

    • After the change:

      CONFIG_TEXT: service ftp
      {
      flags = IPv6
      disable = no
      socket_type = stream
      protocol = tcp
      wait = no
      user = root
      instances = UNLIMITED
      per_source = UNLIMITED
      server = /usr/sbin/in.proftpd
      server_args = -c /etc/proftpd.conf -S 0.0.0.0
      }

  3. Restart the service xinetd:

    # service xinetd restart
