- 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.
Opening port "21" to an ftp server from a cluster

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:
For more detailed information on connecting to an FTP server using MATLAB, refer to the MathWorks documentation at the following link:
Hope this helps!
