Hi all,
I was wondering how to access files from an ftp server from within a supercomputer cluster.
The matlab code is simply:
ftpobj = ftp('ftp.ngdc.noaa.gov')
mget(ftpobj,'README.txt');
This runs and produces the output while running from the matlab window whereas while running on the cluster, it says Could not open a connection to "ftp.ngdc.noaa.gov", port "21" (attached is the screenshot - cluster.png). Is there a way to access files from ftp server by opening a connection from within a clsuter?
Thanks.

Hi Mahith
I understand that you are facing issues in establishing an FTP connection from the cluster.
The potential causes for the connection issue could be as follows:
  • Port restrictions: The cluster might have restrictions on specific ports, including port 21 used by FTP, which could be preventing the cluster from establishing an FTP connection.
  • Firewall restrictions: The cluster's firewall settings may be blocking outgoing FTP connections, preventing the person from accessing the FTP server.
For more detailed information on connecting to an FTP server using MATLAB, refer to the MathWorks documentation at the following link:
Hope this helps!
