If you only have ftp access to a server, you can use ncftp command to transfer the files.

Install in ncftp

 yum install epel-release
 yum install ncftp

Now to transfer files

ncftpget -T -R -v -u "ftpuser" -p "yourpass" ftp-server-name.net /full/destination/path/in/server /source-folder

Above command will transfer contents from source-folder in your remote server to /full/destination/path/in/server/ in your host server. Folder source-folder will be recreated in the host server. For eg. after executing the above command, you can find the contents in the following location in your host server.

/full/destination/path/in/server/source-folder
