Explizit Authentication Problem 530 with pure-ftpd and FTP-Connection

I put on a new Virtual-Server from HostEurope with the Ubuntu 18.04 HowTo and 2 other Add-Ons:

1. https://www.howtoforge.com/tutorial...l-pureftpd-bind-postfix-doveot-and-ispconfig/
2. https://www.howtoforge.com/tutorial/securing-ispconfig-3-with-a-free-lets-encrypt-ssl-certificate/
3. https://www.goover.de/article/7-installieren-mehrerer-php-versionen-mit-ispconfig3-und-ubuntu-18-04/

and except for 1-2 smaller issues (pureftpd.conf existed), everything is running fine. The only problem I have, is when I try to connect to the server over FileZilla, it will not connect anymore. It worked, but now, after putting on another FTP-User for another Web (and maybe after some other system-updates - not shure, when this problem started), it will not connect anymore. I already tried with and without certificate, renewed the certificate, configured pure-ftpd without TLS, but nothing seems to help:

Code:

Apr 14 11:25:59 mail pure-ftpd-mysql[3810]: Starting ftp server: Running: /usr/sbin/pure-ftpd-mysql-virtualchroot -l mysql:/etc/pure-ftpd/db/mysql.conf -l pam -O clf:/var/log/pure-ftpd/transfer.log

Already configured/tried (connect to mysql-db via console -> works):

Code:

PassivePortRange -> 40110 40210
DontResolve -> yes

ForcePassiveIP -> doesn't work
IPV4Only -> doesn't work
TLS -> with or without, doesn't matter

MySQLServer: 127.0.0.1 (syslog) ->

auth.log:

Apr 14 11:42:53 mail pure-ftpd: pam_unix(pure-ftpd:auth): authentication failure; logname= uid=0 euid=0 tty=pure-ftpd ruser=xxx_web2_cms rhost=

Any idea, what else I could check or could be responsible for this behavior?

 

Hi Till,
would have been nice, but even with cyberduck I'm getting the same message. I also have another Server, running Ubuntu 16.04, that works with FileZilla without any problems.

 

More or less, my setup went through these standard steps:

Code:

1. apt-get update, apt-get upgrade, apt-get dist-upgrade
2. apt-get install update-inetd
3. Für VPS-Server:
   ln -s /aquota.group /quota.group
   ln -s /aquota.user /quota.user
4. dpkg-reconfigure locales
   dpkg-reconfigure tzdata
5. apt-get install localepurge
   localepurge
6. apt-get install ssh openssh-server
7. dpkg-reconfigure dash (-> Use dash as default system shell: Nein)
8. Für VPS-Server (HostEurope):
   Hostnamen anpassen nach Anleitung
9. https://www.howtoforge.com/tutorial/perfect-server-ubuntu-18.04-with-apache-php-myqsl-pureftpd-bind-postfix-doveot-and-ispconfig/

-> phpmyadmin weglassen (manuell einrichten)
-> apt-get install aspell-de
-> Für Pure-FTPd (vor "openssl req -x509 ..."):
   openssl dhparam -out /etc/ssl/private/pure-ftpd-dhparams.pem 2048

-> Für VPS-Server:
   Anpassung der /fstab überspringen

-> neue Version 2.21 von jailkit verwenden
-> roudcube weglassen (manuell einrichten)

10. https://www.howtoforge.com/tutorial/securing-ispconfig-3-with-a-free-lets-encrypt-ssl-certificate/

-> openssl dhparam -out /etc/ssl/private/pure-ftpd-dhparams.pem 2048
-> service pure-ftpd-mysql restart

-> apt-get install nano
-> update-alternatives --config editor (nano auswählen)
-> incrontab -e
-> /etc/letsencrypt/archive/mail.xxxxx.de/ IN_MODIFY ./etc/init.d/le_ispc_pem.sh
-> STRG + O / STRG + X

13. https://www.howtoforge.com/perfect-server-debian-10-buster-apache-bind-dovecot-ispconfig-3-1/#-install-phpmyadmin-database-administration-tool
14. https://www.goover.de/article/7-installieren-mehrerer-php-versionen-mit-ispconfig3-und-ubuntu-18-04/
    nachträglich kontrollieren (Ubuntu 18.04 nutzt PHP 7.2):
    update-alternatives --config php
    update-alternatives --config php-cgi
15. Nur Abhängigkeiten installieren (php, ffmpeg, etc.):
    https://www.allerstorfer.at/install-nextcloud-15-on-ubuntu-18-04-with-ispconfig-31/
16. vhost.conf.master anpassen (sonst funktionieren die typo3-links nicht)
    Kopie in /conf-custom erstellen und "Options +SymlinksIfOwnerMatch" in
    "Options +FollowSymLinks" ändern
17. apt-get install graphicsmagick

These steps are already working on my dedicated Hetzner Server for Ubuntu 16.04 and have been partly corrected for the VPS-Setup. In my opinion, everything should be ok, but...I'm a bit helpless now. Any chance, maybe to order some help from you or Florian to check the setup?

 

No shell user.

I don't know, maybe I will cancel the VPS-Server again. I'm not that satisfied with HostEurope and their virtual Servers anymore...so maybe it's not worth it to put too much time in this rather than getting a real dedicated server again. Thanks for your help, I will keep the business support in mind, when I need it
