Bei der Konfiguration von vsftpd auf meiner ec2-Instanz ist ein sehr seltsames Problem aufgetreten: Ich habe den FTP-Server so konfiguriert, dass er FTP über TLS verwendet, und bei Filezilla hat es problemlos funktioniert. Allerdings konnte ich mit keinem FTP-Modul eines Texteditors eine Verbindung herstellen (ich habe es mit Notepad++ und Webstorm versucht). Ich dachte, das Problem liege vielleicht beim SSL, also habe ich es zunächst auf einfaches, unsicheres FTP geändert und versucht, es zum Laufen zu bringen. Jetzt funktionieren die FTP-Clients wieder einwandfrei (Filezilla, Total Commander), aber die oben genannten Texteditoren geben mir nach erfolgreicher Verbindung den folgenden Fehler aus:
Failure retrieving contents of directory /
Ich habe alles versucht, aber im Moment habe ich keine Ahnung, was das Problem sein könnte. Hier sind meine vsftp-Konfigurationen:
listen=NO
listen_ipv6=YES
local_enable=YES
write_enable=YES
dirmessage_enable=YES
use_localtime=YES
xferlog_enable=YES
connect_from_port_20=YES
chroot_local_user=YES
chroot_list_enable=NO
secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=ftp
ssl_enable=NO
pasv_enable=YES
pasv_min_port=1024
pasv_max_port=1048
port_enable=YES
pasv_address=[EC2_PUBLIC_DOMAIN]
pasv_addr_resolve=YES
Hat jemand eine Idee, wo das Problem liegen könnte? Jede Hilfe ist willkommen. Danke.

Sa 14. Jan 20:01:38 2017 [pid 8103] [dev_back] FTP-Antwort: Client "::ffff:178.48.165.229", "227 Entering Passive Mode (0,0,0,0,4,2)."
Dies sieht nach einem Fehler des vsftpd-FTP-Servers aus, wenn die Öffentlichkeit pasv_addressfestgelegt ist und der Server eine (lokale) IPv6-Adresse hat (was bei EC2 der Fall ist).
Ich habe mehr über den Fehler in der Frage zu Serverfehlern gepostet.Passive Vsftpd-Antwort mit 0,0,0,0-Adresse, sogar mit korrekter Pasv-Adresse.
FileZilla kann die ungültige IP-Adresse ignorieren:
14.01.2017 21:27:42 4856 1 Antwort: 227 Wechsel in den passiven Modus (0,0,0,0,4,12).
14.01.2017 21:27:42 4856 1 Status: Der Server hat eine passive Antwort mit einer nicht routbaren Adresse gesendet. Stattdessen wird die Serveradresse verwendet.
Aber Notepad++ kann das nicht.
