4: Using Setup Mode for Configuration

Encryption only applies to the port selected for tunneling (default 10001), regardless of whether you are using TCP or UDP.

Generally, one of two situations applies.

‹Encrypted XPort-to-XPort communication (and in the future, XPort communication to other Lantronix device servers) is supported without extra effort.

‹The XPort uses standard AES encryption protocols. To communicate successfully, products and applications on the peer side must use the same protocols and the same shared key as the XPort. To ease the development process, Lantronix provides an AES encryption DLL for Windows and protocol source code samples. See the document entitled Encryption Enabling Your Serial Device on the Lantronix web site (www.lantronix.com) for more instructions and sample code.

The following export agreement is required for the optional encryption:

I agree that I will not export or re-export this software file to a national resident of Cuba, Iran, Iraq, Libya, North Korea, Sudan, Syria or any other country to which the United States has embargoed goods; or to anyone on the US Treasury Department's list of Specially Designated Nationals and Blocked Persons, US Commerce Department's Table of Denial Orders and Entitles List, or the US State Department's Debarred List. By receiving this software, I am agreeing to the foregoing and I am representing and warranting that I am not located in, under the control of, or a national or resident of any such country or on any such list.

Encryption Tutorial

Rijndael is the block cipher algorithm chosen by the National Institute of Science and Technology (NIST) as the Advanced Encryption Standard (AES) to be used by the US government. The XPort supports 128, 192 and 256 bit encryption key lengths.

Follow the steps below to configure AES encryption on the XPort.

Note: Configuring encryption should be done through a local connection to the serial port of the XPort, or via a secured network connection. Initial configuration information including the encryption key is sent in clear text over the network.

1.Telnet to the configuration port on the XPort (Port 9999).

Example Telnet command syntax is shown below. In the command examples below, replace the x's with the IP address of the XPort.

Microsoft Windows command syntax: telnet xxx.xxx.xxx.xxx 9999 Unix

command syntax: telnet xxx.xxx.xxx.xxx:9999

2.When prompted, press Enter to go into Setup Mode.

3.At the Change Setup menu, select option 6 for security.

4.When prompted to enable encryption, press Y.

5.Enter the encryption key length when prompted. XPort supports 128-, 192- and 256-bit encryption key lengths.
