Guten Tag liebe Community,
ich hoffe, ihr könnt mir bei meinem Problem weiterhelfen:
Seit dem letzten Update (Debian GNU/Linux), scheitert der Aufbau einer FTP-Verbindung häufig beim ersten Versuch bzw. bei anderen Verbindungsversuchen auch.
[16:28]root@server2:~$ ftp ftp -d ftp://vts_backup:passwort@viathinksoft.de/mysql.zip -o /daten/backup/web/mysql.bak.zip_
isipv6addr: got 0 for ftp://vts_backup:passwort@viathinksoft.de/mysql.zip
parse_url: user `vts_backup' pass `passwort' host viathinksoft.de port ftp(21) path `mysql.zip'
fetch_ftp: user `vts_backup' pass `passwort' host viathinksoft.de port ftp path `mysql.zip' dir `<null>' file `mysql.zip'
Connected to viathinksoft.de.

ftp_login: user `vts_backup' pass `passwort' host `viathinksoft.de'

331 Password required for vts_backup.
---> PASS XXXX
421 Service not available, remote server has closed connection.
ftp: Login failed.

2ter Versuch (direkt danach):

Beim 2ten Versuch würde der Datentransfer natürlich weiter laufen, ich habe ihn nur abgebrochen.
Ein Debug-Lauf von ProFTPD gab folgendes Ergebnis:1ste, gescheiterte Verbindung:
