∟Test FTP Access Locally on CentOS

This section provides a tutorial example on how to use the 'ftp' client program to access the 'vsftpd' server locally on the same CentOS computer.

After updating vsftpd configuration and setting up my "ftp" home directory, now I am ready to test my FTP access locally on the same CentOS computer as the vsftpd server.

1. Make sure the "ftp" client program is available.
