2: Introduction

Addresses and Port Numbers

Hardware Address

The hardware address is also referred to as the Ethernet address, physical address, or MAC address. Sample hardware address:

00---14-1B-18

00:::14:1B:18

IP Address

Every device connected to an IP network must have a unique IP address. This address references the specific unit.

Port Numbers

Every TCP connection and every UDP datagram is defined by a destination and source IP address, and a destination and source port number. For example, a Telnet server commonly uses TCP port number 23.

The following is a list of the default server port numbers running on the xSenso:

TCP Port 22: SSH Server (Command Mode configuration)

TCP Port 23: Telnet Server (Command Mode configuration)

TCP Port 80: HTTP (Web Manager configuration)

TCP Port 21: FTP

UDP Port 30718: LDP (Lantronix Discovery Protocol) port

TCP/UDP Port 10001: Tunnel 1 (see note below)

UDP Port 1900 and TCP Port 30179: UPnP

Note: Additional TCP/UDP ports and tunnels will be available, depending on the product type. The default numbering of each additional TCP/UDP port and corresponding tunnel will increase sequentially (i.e., TCP/UDP Port 1000X: Tunnel X).

Product Information Label

The product information label on the unit contains the following information about the specific unit:

Bar code

Note: The hardware address on the label is also the product serial number. The hardware address on the label is the address for the Ethernet (eth0) interface.
