    Have you checked the "FTP Access" checkbox in the site settings?
    Did you get any errors in the logfiles (auth.log)?

    user can login to web-FTP by checking "FTP Access"
    but
    can not login from remote FTP client. It's like I don't have home directory to login to.
    error
    #############
    530 Login incorrect.
    QUIT
    221 Goodbye.

    I tried the username and password to localhost and it works.

    Webftp is a normal FTP-Client that uses only FTP commands and connects to localhost. When you can login from localhost and not from a remote computer, it might be a firewall issue.

    i tried ftp from remote server that has no fireall restriction and i could not login either. So it seems the firewall is not the issue from my machine.

    I did not setup any firewall restriction on localhost server. I don't understand what's going on.


    Thank you for your help.

    iptables listing and /var/log/secure and /var/log/messages entries

    I am experiencing the same issue.
    I can login to SSH from a remote system using one of the user logins, but am unable to use that same username/password pair to login to FTP remotely, but I can login with that username password locally when I connect to localhost.

    Till: Regarding the question posed to Pete, here is my iptables output:

    # iptables -L -t filter
    Chain FORWARD (policy ACCEPT)
    target prot opt source destination

    Chain INPUT (policy ACCEPT)
    target prot opt source destination

    Chain OUTPUT (policy ACCEPT)
    target prot opt source destination

    # iptables -L -t nat
    Chain OUTPUT (policy ACCEPT)
    target prot opt source destination

    Chain POSTROUTING (policy ACCEPT)
    target prot opt source destination

    Chain PREROUTING (policy ACCEPT)
    target prot opt source destination

    # iptables -L -t mangle
    Chain FORWARD (policy ACCEPT)
    target prot opt source destination

    Chain INPUT (policy ACCEPT)
    target prot opt source destination

    Chain OUTPUT (policy ACCEPT)
    target prot opt source destination

    Chain POSTROUTING (policy ACCEPT)
    target prot opt source destination

    Chain PREROUTING (policy ACCEPT)
    target prot opt source destination


    This is very confusing to me. Here are the relevant messages from /var/log/secure:
    Aug 13 18:58:44 webhost sshd[28692]: Accepted password for web2_brandon from REMOTEHOST port 51960 ssh2
    Aug 13 19:04:05 webhost proftpd[28887]: webhost.mydomain.tld (127.0.0.1[127.0.0.1]) - USER web2_brandon: Login successful.
    Aug 13 19:04:40 webhost proftpd[28900]: webhost.mydomain.tld (REMOTEHOST[REMOTEHOST]) - USER web2_brandon (Login failed): Incorrect password.


    and if you can believe it, I used the same password for all three of those login attempts.

    Here are some entries from /var/log/messages:

    Aug 13 19:03:57 webhost proftpd[28887]: webhost.mydomain.tld (127.0.0.1[127.0.0.1]) - FTP session opened.

    successful remote ftp connection

    Wow, I got connected... I have been struggling with this for a few days.

    So I use Filezilla (http://filezilla.sourceforge.net/) as my ftp client.
    Since I was still having problems, and not getting anywhere with looking at my pam.d/proftpd file I decided to play around with my client for a few.
    First off... you HAVE to have puTTY installed on your windows PC.
    In Filezilla, add your ISPConfig server in Site Manager.
    Under Servertype: choose SFTP using SSH2
    Then use your ISPConfig user that is configured, e.g. webx_username and the password you assigned to this user.
    I got connected and am now happily using if to load files and remove them as well.

    Hi Brandon,

    this is another solution to upload files to your server but it does not solve the FTP problem because the proftpd daemon is not envolved at all when uploading files in sftp mode. Maybe falko has an idea what might be wrong with your proftpd installation.

    that worked

    Thanks a lot Falko. I thought I had looked all through the forums regarding this issue, but apparently not.

    Adding /etc/pam.d/ftp with those entries worked like a charm. Thanks again.
