4 Using the DS-L1 via a Network

 

 

Limiting connectable IPs

If you want to limit the IP addresses connectable to the DS-L1, select the “IP Authority” check box. To register the IP addresses that are allowed to connect to the DS-L1, follow the procedure described below.

Method for registering the IP addresses that are allowed to connect

1)Insert a CF card into the card slot of your computer.

NOTE: A card adapter may be needed depending on your computer.

2)Create a directory named \NET in the CF card.

3)Create a text file that contains a list of the IP addresses that are allowed to connect to the DS-L1.

Description example 192.168.10.1 192.168.10.10 192.168.10.36 192.168.21.*

A wildcard (*) can be used. In the above example, 1 to 254 are effective.

4)Add an extension “.ip” to the text file and save it in the \NET directory or a directory hierarchically below it.

(Example: Autho.ip)

5)Insert the CF card into the DS-L1.

6)Connect to the DS-L1 from the PC by Telnet and run the command “w_IPA” to register the IP addresses. (Refer to “4.5 Using Telnet Commands to Operate on the DS-L1” in Chapter VI.)

Saving logs of connected users (NETLOG function)

A record can be kept of the IP addresses of the machines that accessed the DS-L1 and of time information. When accessed from a WEB browser, access logs are kept only when the user IDs have been set in the Internal Server on the DS-L1 side. However, these logs disappear when the DS-L1 is powered off.

Run the Telnet command “w_NLGON,” and the initial settings can be changed to display

NETLOG.

To get the data contained in the logs, access the DS-L1 using an FTP command, and get and read the file labeled NETLOG.txt that is stored in the RAMIBOX directory or a directory hierarchically below it.

To get the data contained in the logs, access the DS-L1 using an FTP command, and get and read the file labeled NETLOG.txt that is stored in the RAMIBOX directory or a directory hierarchically below it.

NETLOG.txt is up to 64 Kbytes in size. If the buffer is filled, the content is automatically erased and new logs are written to the file beginning with the 0 byte. However, if transfers to an external server have been set by the w_NLFTON command, the log data is transferred to the external server before being erased. The file name of this log data consists of the letters NL, the date (months, days and hours), and the extension “.txt.” (When transferred at 12 o’clock on April 1, the file name would be NL040112.txt.)
