Trying to access FTP Server from command line (shell), Error 530.

Question

_{Monday, April 22, 2019 10:43 AM}

Hello.

I'v configured a server ubuntu 18.04 in Azure, but when I try to access an external FTP server using a command line, I got this error:

Login failed.
Remote system type is Windows_NT.
ftp> 530 User cannot log in, home directory inaccessible

The credencial and address are correct, because I use the same informations in another Ubuntu 18.04 (local) and its work..

At shell,i'm doing

ftp     ftp.server.com.br

user  (ask)

password (ask)

Could someone help me ?

Thanks.

Hi,

I assume your FTP server is in Azure. 

If you get a prompt for User name and password, then Connectivity is there. Now, we need to look into other aspects. 

What mode are you using to connect? (Active or Passive)

Can you use FTP client such as FileZilla in Passive mode to connect?

Also make sure the Passive ports are open in NSG.

Hello,

Thanks for answer me.

Sorry, my FTP server is out azure...

I think the ports are closed, and its a security problem. 

How can I check passive ports are open in NSG ?

So you are trying to access FTP server from Azure VM. Correct?

If you use command line, it will not work. 

Reference: https://social.technet.microsoft.com/wiki/contents/articles/52553.azure-troubleshooting-active-ftp-client-cannot-access-a-public-ftp-server.aspx

Try using 3rd party FTP client from Azure VM. Also use Passive mode. By default Azure NSG allows outbound traffic. So no changes are required in NSG.

ah..

Well, and if I changed my external ftp server to inside azure (I'm thinking in created a ftp server in Linux Machine) it should work ?

It depends on the client from where you are accessing the FTP server. 

If it is an Azure FTP active client, it will not work. You can check the Wiki which I have mentioned for reference.

I don't know if only Azure FTP Active client has this limitation..

I installed other FTP Client and the same error. I'm very frustated, because in my Ubuntu local instalation work perfectly...

999_FluentFTP.FtpCommandException: User cannot log in, home directory inaccessible.
   at FluentFTP.FtpClient.Authenticate(String userName, String password)
   at FluentFTP.FtpClient.Connect()

You can take a packet capture in the client and check what's going on. Without which suggesting an action is not possible.
