Hey, ich wollte meinen Raspberry Pi als FTP-Server nutzen.
Habe also proftdp installiert. Der Active-Mode klappt auch wunderbar.
Weil ich den Server allerdings von außen erreichen möchte bleibt ja nur der Passive-Mode. Habe die proftpd.conf so angepasst:
#
# /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes, reload proftpd after modifications, if
# it runs in daemon mode. It is not required in inetd/xinetd mode.
#
# Includes DSO modules
Include /etc/proftpd/modules.conf
# Set off to disable IPv6 support which is annoying on IPv4 only boxes.
UseIPv6 on
# If set on you can experience a longer connection delay in many cases.

# Use this directive to release that constrain.

# Port 21 is the standard FTP port.
Port 59999
# In some cases you have to specify passive ports range to by-pass
# firewall limitations. Ephemeral ports can be used for that, but
# feel free to use a more narrow range.
PassivePorts 60000 60100
# If your host was NATted, this option is useful in order to
# allow passive tranfers to work. You have to use your public
# address and opening the passive ports used on your firewall as well.

# refresh any configured MasqueradeAddress directives every 8 hours

# To prevent DoS attacks, set the maximum number of child processes
# to 30. If you need to allow more than 30 concurrent connections
# at once, simply increase this value. Note that this ONLY works
# in standalone mode, in inetd mode you should use an inetd server
# that allows you to limit maximum number of processes per service
# (such as xinetd)
MaxInstances 30
# Set the user and group that the server normally runs at.

Im Router habe ich die Ports 59999 - 60100 weitergeleitet. Irgendwas klappte da aber noch nicht mit der Weiterleitung deswegen hab ich es ohnhin erstmal intern probiert.
Allerdings habe ich da Probleme mit dem Passiven Modus. Die Portweiterleitung sollte ja erstmal keine Rolle spielen, da ich über die interne IP zugreife und somit kein wirkliches NAT dazwischenliegt.
Ich kann zwar eine Command-Verbindung auf Port 59999 herstellen, aber mit der Data-Verbindung scheint das nicht so ganz hinzuhauen. Sowohl in Filezilla als auch mit gFTP gibt es folgenden Fehler.
Status: Verbinde mit 192.168.2.140:59999...
Status: Verbindung hergestellt, warte auf Willkommensnachricht...

(Unter Linux). Unter Windows kommt ein ähnlicher Fehler, nur dass der letzte Befehl da "MLSD" ist anstatt "LIST".
Active-Mode klappt wie schon erwähnt einwandfrei.
Hoffe mir kann da jemand helfen. Hab schon viel gegoogelt und die conf Datei angepasst mit Sachen wie:
aber das hat alles nichts geholfen. Bin etwas am verzweifeln.
Grüße
