Download FTP directory and files in remote Ubuntu server via SSH

I want to download the files listed in a FTP directory, ftp://. On my WINDOWS laptop when I put this link in the address bar of file explorer, I am able to view and download its content as shown below,

But I want to download these files in a remote UBUNTU server via ssh and have tried the following with corresponding error message,

1. Both wget -r ftp:// and wget -m ftp:// gives the following error

--2021-08-24 09:18:07-- ftp:// => ‘

Retrying.

A more detailed error report using wget -r -v -d ftp:// gives the following error report,

2. I even tried ftp and sftp and they also do not work.

Interestingly if I execute it on Google Colab I am able to download the ftp directory. But for my remote Ubuntu system I get the above-mentioned errors. Note that one does not require username or password to access it.

If ssh is enabled, and you know the path then it should be simple to do from either of the hosts.

scp :/ftp_root_folder/NAMA3DS1_COSPAD1/Avi_videos/HRC_00_Reference/. /home/someUser/DestinationFolder/

If scp is not available.

ftp
open ftp.ivc.polytech.univ-nantes.fr
cd /NAMA3DS1_COSPAD1/Avi_videos/HRC_00_Reference/
lcd ~/MyLocalPath/
pull *

I just tried this on your host, and it worked You might need to enable passive mode with pasv
