- Plesk Onyx for Linux
- Passive FTP connection does not work after enabling Plesk Firewall Tools & Settings > Firewall > Enable .
Cannot list directory when connecting in passive mode:
227 Entering Passive Mode (192,0,2,2,176,121).
ftp: connect: Connection timed out
ip_conntrack_ftp module is not loaded:
# lsmod | grep conntrack_ftp
The described behavior is expected if ip_conntrack_ftp module is not loaded.
This is Plesk bug with ID # PPPM-6187. The notification in Plesk UI will be added in future Plesk updates.
As a workaround, configure passive ports as described in the article How to configure a passive ports range for ProFTPd on a server behind a firewall .
