    Sorry for opening a thread on this, but solution I tried for 2 hours did not work.

    If find the following errors while trying to log in with FTP:
    Code:
    Sep 20 12:55:59 aerotronicvds proftpd[9079]: localhost.localdomain (::ffff:130.89.137.92[::ffff:130.89.137.92]) - FTP session opened. 
    Sep 20 12:55:59 aerotronicvds proftpd: PAM-listfile: Refused user ***user*** for service proftpd
    Sep 20 12:55:59 aerotronicvds proftpd(pam_unix)[9079]: authentication failure; logname= uid=0 euid=0 tty= ruser= rhost=::ffff:130.89.137.92  user=***user***
    Sep 20 12:56:01 aerotronicvds proftpd[9079]: localhost.localdomain (::ffff:130.89.137.92[::ffff:130.89.137.92]) - PAM(***user***): Authentication failure. 
    Sep 20 12:57:28 aerotronicvds proftpd[9145]: localhost.localdomain (::ffff:130.89.137.92[::ffff:130.89.137.92]) - FTP session opened. 
    Sep 20 12:57:28 aerotronicvds proftpd: PAM-listfile: Refused user ***user*** for service proftpd
    Sep 20 12:57:30 aerotronicvds proftpd[9145]: localhost.localdomain
    I have followed: http://www.howtoforge.com/perfect_setup_centos_4.4_p6

    So /etc/pam.d/ftp is as should

    passwd:
    ***user***:x:10018:10002: *** Information:/var/www/web2/:/dev/null

    Also tried:
    ***user***:x:10018:10002: *** Information:/var/www/web2/./:/bin/false
    ***user***:x:10018:10002: *** Information:/var/www/web2/./:/etc/shell

    Also changed the owner of the files, but that's not where the problem lies.

    No luck. I think I better send proftpd.conf per PM.

    Thanks so much in advance for your help!

    Can you post your proftpd.conf here?

    Can you comment out these two lines and restart ProFTPd?

    Code:
    AuthPAMConfig			proftpd
    AuthOrder			mod_auth_pam.c* mod_auth_unix.c
    Does it work then?

    Hi Falko,
    Thanks for your time, it works better now:
    Code:

    But other options of different topics don’t work (using web2_username does not work, passive mode does not work, firewall port 21 is open, proftpd is listening right, also web-ftp of ispconfig does not work)
    Code:

    There is also a problem with a double userId for that user (id ***user*** gives dkfilter), but another user that has a unique id can’t login also. Also:
    Code:
    -bash-3.00# proftpd -t

     - setting default address to 127.0.0.1
    Syntax check complete.
    I have no idea anymore…

    Can you check that your user is existing in /etc/passwd, and that there are only unique user IDs in /etc/passwd?

    It appeared that the user was accidentally in ftpusers, so that it's conn. was refused ;-) Afterwards I was having problems with 'directory listing', but that could be solved with passive connection.

    Thanks for your time!
