Perhaps this can be useful to browse the FTP server tree (directory
names finish by '/', others are files):

def recursive_listing(ftp, path)
        liste_ftp = Array.new
        list = ftp.ls(path)
        if list.length == 0
                return []
        end
        if list[0].split[0] == 'total'
                list.delete_at(0)
        end
        if list[0].split[8] == '.'
                list.delete_at(0)
        end
        if list[0].split[8] == '..'
                list.delete_at(0)
        end
       list.each { |str|
               if str.split[0].index('d') == 0
                       liste_ftp += [path + "/" + str.split[8] + "/"]
                       liste_ftp += [recursive_listing(ftp,  path + "/"
+ str.split[8])]
               else
                       liste_ftp += [path + "/" + str.split[8]]
               end
       }
       return liste_ftp.flatten
end

ftp = Net::FTP.new('ftp_serveur')
ftp.login('login', 'passwd')
ftp_list = recursive_listing(ftp, 'starting_directory')
ftp.close


It might need some corrections depending your FTP server configuration.
