Media Server User’s Guide

The following table describes the labels in this screen. 

The media server application allows you to share media files with media clients.

Applications > FTP

FTP

Enable FTP

You can use FTP to send files to the NSA or get files from the NSA. Select this check box 
to allow users to connect to the NSA via FTP; otherwise clear the check box.

Connection Limit Enter the maximum number of concurrent FTP connections allowed on the NSA in this 

field. See your screen for your model’s connection limit.

Idle Timeout

Enter the length of time that an FTP connection can be idle before timing out. The 
timeout limit is 300 minutes.

Port Number

This is the port number used by the NSA for FTP traffic.

Enable Anonymous 
FTP Access

Select this check box to allow any user to log into the NSA using ‘FTP’ or ‘anonymous’ 
as a username and no password. Any other name is considered a username, so must be 
valid and have a corresponding correct password.

Customize the port 
range for data 
transfer

Select this check box to assign a port range for FTP clients to use when downloading 
files from the NSA using passive mode.

The connection limit is restricted to half of the port numbers within the range if this 
value is smaller than the one configured in the Connection Limit field. For example, 
you specified a port range from 1024 to 1029 and configured 10 in the Connection 
Limit field. The FTP connection limit will only be 3 (6 ports in the range divided by 2) 
because it is the smaller value.

Starting Port

Enter the first port number in the range. Choose from 1024 to 65535.

Ending Port

Enter the last port number in the range. Choose from 1024 to 65535.

Character Set

The NSA uses UTF-8 (8-bit UCS/Unicode Transformation Format) format for FTP by 
default. If the NSA’s folders, or file names do not display correctly in your FTP client, 
select the appropriate language encoding here. 

This setting applies to all FTP client connections to the NSA. It does not affect your 
Windows/CIFS connections (it will not correct the character display in Windows 
Explorer).
