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)
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 -A
 
at 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)
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.
