# vi /etc/vsftpd/vsftpd.conf ●Line 12 : No anonymous login (confirmed) anonymous_enable=NO ●Line 39：Log transfer records (confirmation) xferlog_enable=YES ●Line 82,83 : Uncomment ( Allow transfer in ASCII mode ) ascii_upload_enable=YES ascii_download_enable=YES ●Line 100,101：Uncomment ( chrootenable ) chroot_local_user=YES chroot_list_enable=YES ●Line 103 : Uncomment (chroot list file specification ) chroot_list_file=/etc/vsftpd/chroot_list ●Line 109 : Uncomment ( Enable batch transfer by directory ) ls_recurse_enable=YES ●Line 114 : Change ( IPv4 enable ) listen=YES ●Line 123 : Change ( IPv6 disable ) listen_ipv6=NO ### Add to last line ### # Use local time use_localtime=YES |
②Add users to allow directory access to upper level
|
1 2 |
# echo "huong" >> /etc/vsftpd/chroot_list In my case I wrote huong |
③ Specify IP addresses to allow connections in /etc/hosts.allow
|
1 2 |
# echo "vsftpd:192.168.11.0/24" >> /etc/hosts.allow 192.168.11.0/24 is the setting that allows all local IP addresses in my environment. |
Write vsftpd:ALL (deny all connections) in /etc/hosts.deny
|
1 |
# echo "vsftpd:ALL" >> /etc/hosts.deny |
This setting overrides hosts.allow. That is, everything is denied, and IP addresses specified in hosts.allow are allowed.
④Enable vsftpd autostart and start it
|
1 2 |
# systemctl enable vsftpd Created symlink /etc/systemd/system/multi-user.target.wants/vsftpd.service → /usr/lib/systemd/system/vsftpd.service. |
|

# systemctl start vsftpd |
⑤From windows side, check if you can connect with FileZilla.
Open the ftp port with firewall before connecting
|
1 2 |
# firewall-cmd --permanent --add-service=ftp # firewall-cmd --reload |
Start FileZilla and select "Site Manager" from the "File" menu.
