Getting Started IP Address Configuration
3 - 3
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.
