FTP 550 Error with Pure FTP

[msklut]

We recently added virtual users to Pure FTP that are able to connect seamlessly to the server. However, now we are seeing 550 errors for 'real' FTP users (not virtual). Thoughts? The folder permissions are set to 0750 and user:nobody for public_html. Anything else we should look at?

FileZilla 550 error
Status: Retrieving directory listing...
Command: PWD
Response: 257 "/" is your current location
Command: TYPE I
Response: 200 TYPE is now 8-bit binary
Command: PASV
Response: 227 Entering Passive Mode (IP_ADDRESS)
Command: MLSD
Response: 550 Can't check for file existence
Error: Failed to retrieve directory listing

These are the steps we followed to enable virtual users for Pure FTP.

Thank you for any suggestions!

Hey there! cPanel doesn't support that type of virtual user creation, so I can't say for sure if that is related to the problem or not. My recommendation would be removing those users and creating additional users through cPanel >> User Manager >> Add User, as that would grant additional FTP user access.

You'll also likely want to ensure that Passive Mode is properly configured in FTP and the server's firewall to ensure the port range is open:

How to Enable FTP Passive Mode | cPanel & WHM Documentation

This document explains how to use the active or passive mode to connect to a File Transfer Protocol (FTP) server.

When I look at the status for Pure FTP, it shows the 'real' user logged in, but in FileZilla I still see a 550 Can't check for file existence error.

While we don't recommend using Filezilla, their team's official response for that error is the user not having permission to access the target directory. Details on that can be found here:

[msklut]

[~]# ls -l /home/admin_user/public_html
drwxr-x--- 19 admin_user nobody 4096 Apr 14 21:07 public_html

These are the target directory permissions. Anything look wrong here?

I don't think the directory permissions would be an issue, but it's how the virtual FTP users were created that is the problem.

Kind of OT, but can you elaborate on why you don't recommend using Filezilla, Rex? It's like the most popular FTP program out there.

Create users through cPanel >> User Manager >> Add User, as that would grant additional FTP user access and check if the issue persists.
I agree with @cPRex that directory permissions wouldn't be an issue, but it's how the virtual FTP users were created that is the problem.

@mtindor - there were some security issues with it a while back as it was distributing malware. We have some additional details here but we leave it a bit vague on purpose: https://support.cpanel.net/hc/en-us/articles/360051892214-How-to-Enable-the-Debug-Log-in-Filezilla
