Plesk Enabling Passive FTP Ports (Linux)

To enable users to connect to your Plesk for Linux server via FTP in the passive mode, you need to manually edit the ProFTPD configuration file and make changes to your firewall policy to let the passive FTP connections through.

First, log in to your server via SSH as the root user. Open the

/etc/proftpd.conf

file for editing and add the following line anywhere in the "Global" section:

PassivePorts 10000 20000

Alternatively, to avoid the config file being overwritten by Plesk or updates create an additional conf file:

vi /etc/proftpd.d/55-passive-ports.conf

and add the lines:

<Global>
PassivePorts 10000 20000
</Global>

Save the changes and restart the xinetd service for the changes to take effect:

systemctl restart xinetd
