b) For IP Address, enter the desired IP address to use for this ETS. The IP
address should be on the same subnet as the PC running EZWebCon.
c) For Subnet Mask, change the values provided only if you wish to use a mask
other than the default. The default value should be correct in most cases.
d) For Loadhost, enter the IP address of the loadhost where you intend to store
your operating code.
3. Click OK.
4. Reboot the ETS. EZWebCon will let you know whether the configuration was
successful.
Note:
If you have an older version of EZWebCon, refer to the ReadMe that was
included with it.
Using a Directed Ping Packet
The ARP/ping method is available under UNIX and Windows-based systems. If the
ETS has no IP address, it will set its address from the first directed IP packet it
receives.
On a UNIX host, create an entry in the host’s ARP table and substitute the intended
IP address and the hardware address of the ETS, then ping the ETS. This process
typically requires superuser privileges. The IP address should be on the same subnet
as the PC running EZWebCon.
Figure 3-3. ARP and Ping on 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 95, the ARP table on the PC
must have at least one IP address defined other than its own. If the ARP table is
empty, the command will return an error message. Type
ARP -A
at the DOS
command prompt to verify that there is at least one entry in the ARP table.
Figure 3-4. ARP and Ping on 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 ETS 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 specified address. If no
duplicate is found, the ETS will use the IP address and will respond to the ping
packet.
The ETS will not save the learned IP address permanently; this procedure is intended
as a temporary measure to enable EZWebCon to establish communication and allow
an administrator to Telnet into the ETS. Once logged in, the administrator can enter
the
Define Server IPaddress
command to make the address permanent.
