    We are in the process of setting up a new server and anytime we try to connect via FTP we get a message stating a successful login, but the connection can not get a directory listing.

    We have tried using the default cPanel user and tried setting up another test FTP account but all ends in the below Error Messsage.

    Code:

    You should follow the directions on cPanel's site for enabling Passive Mode FTP support on the server.

    How to Enable FTP Passive Mode - cPanel Knowledge Base - cPanel Documentation

    In case you don't want to read that, below is what I do.

    You'll want to make sure you have Passive Mode FTP support enabled by uncommenting the appropriate line in /etc/pureftpd.conf and then making sure those ports are open in your firewall.

    1. Edit /etc/pureftpd.conf

    Uncomment the below line and save /etc/pureftpd.conf

    PassivePortRange 30000 50000

    2. Run /scripts/restartsrv_pureftpd to restart pureftpd

    3. Make sure your firewall is allowing incoming connections in the PassivePortRange

    If you are using CSF, look in /etc/csf/csf.conf for a line starting with TCP_IN =

    TCP_IN = "20,21,22,25,26,53,80,110,113,143,443,465,587,967,993,995,2077,2078,2082,2083,2086,2087,2095,2096,30000:35000"

    Notice how the allowing of ranges of ports is set up in CSF - you use 30000:35000.

    4. Run csf -r to apply the CSF config change

    5. In your FTP client make sure you are using Passive mode FTP. I never do this. But I know my firewall on my PC will not block outbound connections from my FTP client. If you aren't sure, then on your PC you will want to force passive mode.

    Hello,

    Yes, as mentioned in the previous post, you should be able to follow the instructions on the following document to address the problem:

    How to Enable FTP Passive Mode - cPanel Knowledge Base - cPanel Documentation

    Starting with version 60, the cPanel installation process will automatically enable passive mode and ensure the required ports are open as part of the standard firewall configuration.

    Thank you.

    I am having these exact same problems. I have tried various things such as work with the firewall, and attempt to change to passive mode. When I am in the Cpanel, looking at etc. file I do not see the files I am supposed to be working with and editing (I read the above suggested documentation). After doing a wizard configuration in my FTP it says I MUST set FTP to passive mode, still having troubles as to how I do that.

    Thoughts?

    Hello @Ally,

    Do you have root access to the system? If so, you need to access the server via the command line as the "root" user in order to make the documented changes to the Pure-FTPd configuration file.

    Thank you.

    ports are opened in the firewall. Everything was working fine until the last update for cPanel.

    Hello,

    Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome.

    Thank you.

    Had the same issues, and this fixed it perfectly. Thank you for taking the time to type this out.

    The Passive Port range was there in pure-ftpd.conf from the start, though a slightly higher range.
    But the ports were NOT open in CSF's TCP_IN.

    I added them and it worked immediately. My only question is: was opening the ports some kind of security risk? If not, why were they not there (listed) in the first place?

    Any time you have to open a port for inbound/outbound access, the cost of doing so needs to be weighed. Because some admins might not allow FTP or some environments might not allow TCP 20 through corporate firewalls, and because people may set their own preference for passive ports, Chirpy probably figured it was best that the admin actually add the passive ports manually rather than have CSF actually try and guess. Just a hunch.

    If you are a server admin who allows FTP access, then you almost certainly will want to make sure that passive mode is supported.

    I'm glad the post helped you out!

    Hi @cPanelMichael , @mtindor ,

    I can still connect to FTP server "Pure-FTP", But I tried to look this and any tutorial won't help. I'd like to enable Pure-FTP firewall to allow IP. I checked in CSF Firewall TCP_IN: there is no for a port in FTP `49152 65534`. I'm confused so. I need to enable FTP firewall to allow IP well.

    You'd need to add the port range at the end of the existing TCP_IN line. For example:

    Code:
    49152:65534
    Thank you.

    Using from VPN test it, they will not let connect another IP from SSH/SFTP, FTP it's working now.

    You're very welcome. I'm glad to see that helped.

    Please open a new thread if you are facing a separate issue with the SSH/SFTP service.

    Thanks!

    Not really, any IP random will not allow connecting to our server. It's working on firewall added for port SFTP/FTP, SSH. You just helpfully me. ;)
