Lantronix MSS100, 1-T2 manual 1Entering ARP and Ping Unix

Getting Started

IP Address Configuration

NOTE: The ARP/ping method only works during the first two minutes of MSS operation. After two minutes, an alternate method must be used or the MSS must be rebooted.

On a UNIX host, create an entry in the hostÕs ARP table and substitute the intended IP address and the hardware address of the server, then ping the server (see Figure 3-1). This process typically requires superuser privileges.

Figure 3-1:Entering ARP and Ping (UNIX)

#arp -s 192.0.1.228 00:80:a3:xx:xx:xx % ping 192.0.1.228

In order for the ARP command to work on Windows, the ARP table on the PC must have at least one IP address deÞned other than its own. Type ARP -Aat the DOS command prompt to verify that there is at least one entry in the ARP table.

If there is no other entry beside the local machine, ping another IP machine on your network to build the ARP table. This has to be a host other than the machine that you're working on. Once there is at least one entry in the ARP table, use the following commands to ARP the IP address to the MSS and make the MSS acknowledge the IP assignment.

Figure 3-2:Entering ARP and Ping (Windows)

C:\ ARP -S 192.0.1.228 00-80-A3-XX-XX-XX

C:\ PING 192.0.1.228

NOTE: There should be replies from the IP address if the ARP command worked.

When the MSS receives the ping packet, it will notice that its IP address is not set and will send out broadcasts to see if another node is using the speciÞed address. If no duplicate is found, the server will use the IP address and will respond to the ping packet.

The MSS will not save the learned IP address permanently; this procedure is intended as a temporary measure to enable EZWebCon to communicate with the server, or allow an administrator to Telnet into the MSS. Once logged in, the administrator can enter the Change IPaddress command to make the address permanent.
