Esistono connessioni di protocollo da tenere presente quando si effettuano connessioni FTP.
Queste connessioni rispondono alla visita dell'utente e sono abilitate quando l'utente corrente è autenticato.
In FTP otterrai questo errore se la modalità passiva non è attiva.
Il seguente file di configurazione è configurato secondo il software vsftpd e tutte le impostazioni sono configurate correttamente e allo stesso tempo non ci sono errori.
Modalità attiva, passiva e consente porte firewall. 2000 a 2500 / TCP
pasv_enable=Yes
pasv_max_port=2500

% 100 File di configurazione Vsftpd fisso: /etc/vsftpd/vsftpd.conf
# Example config file /etc/vsftpd/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=YES
#
# Uncomment this to allow local users to log in.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
#anon_upload_enable=YES
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# The target log file can be vsftpd_log_file or xferlog_file.
# This depends on setting xferlog_std_format parameter
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=NO
#
# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using "root" for uploaded files is not
# recommended!

Una volta che hai tutte queste impostazioni, ricorda di configurare le impostazioni del firewall.
- TCP in arrivo: dal 2000 al 2500 e 21
- TCP in uscita: da 2000 a 2500 e 21
