[Gelöst] Probleme mit ProFTPd

[U-Tux]

Hey Leutz.

Ich verzweifle schon die letzten paar Tage an meinem kleinen VServerchen (Etch); vielleicht könnt ihr mir ja helfen.
Oder ich seh grad den Wald vor lauter Bäumen nicht.

Mein FTP (ProFTPd 1.3.0) lässt keine Connections zu - warum auch immer.
Das Starten bzw. Restarten kommt ohne Fehler:

Code:

root@HOST:/etc/proftpd# /etc/init.d/proftpd restart
Stopping ftp server: proftpd.
Starting ftp server: proftpd.

Er läuft auch, wie mein ps mir erzählt:

Code:

nobody   22406  0.0  0.0  53212  1748 ?        Ss   12:45   0:00 proftpd: (accepting connections)

Meine conf:

Code:

#
#       ispCP OMEGA ProFTPd config file
#
#
#
# Includes required DSO modules. This is mandatory in proftpd 1.3
#
Include /etc/proftpd/modules.conf

TLS ist aus

Wenn ich jetzt bspw. ne FTP-Verbindung von aussen aufmache, kommt:

Code:

421 Service not available, remote server has closed connection

Ein Telnet auf der Kiste selbst macht folgendes:

Code:

root@HOST:/etc/proftpd# telnet DOMAIN.TLD 21
Trying IP-ADRESS...
Connected to DOMAIN.TLD.
Escape character is '^]'.
Connection closed by foreign host.

ergo, fliege ich nach den connect direkt wieder raus, was nicht so toll ist.

Das Log spuckt keinen Fehler oder derartiges aus.

Irgendwer ne Idee, wo ich noch suchen kann bzw. was ich noch testen kann?
