Install Guide

6. Verify that the RARP daemon is running:

ps-ax grep RARP (for BSD UNIX) or ps-ef grep RARP (for System V UNIX)

Otherwise, start the RARP daemon by typing:

/usr/etc/rarpd-a or /etc/rarpd-a

If successful, the SYS LED flashes five times per second until the 4711H resolves its IP address. Then it flashes once per second after address resolution.

Note: The IP address in this case is stored in RAM. Hence, if the MIL-4711H is powered off, the address will be lost and when the unit is powered on, the MIL-4711H will RARP again.

Setting the IP Address with BOOTP

BOOTP allows a diskless client machine to discover its own IP address. Unlike RARP, BOOTP is IP/UPD based and it can pass through routers.

To set the IP Address with BOOTP on a Sun system:

1.Verify that you have BOOTP (usually located in the /usr/etc directory).

2.Use a text editor to open the /etc/hosts file.

3.Add the host name and address, and then save the file. For example, for a MIL-4711H called alpha with an IP address 192.185.2.3, add this line:

192.185.2.3 alpha

4.Edit BOOTP in the /etc directory containing the hostname of the MIL-4711H, hardware type, hardware address, and the IP address. Format the entry:

<hostname of MIL-4711H>:ht=1:ha=<hardware address>:ip=<ip address>

For example, an entry named alpha, with a hardware address of 0040c8010203 and an IP address of 199.86.12.183:

alpha:ht=1:ha=0040c8010203:ip=199.86.12.183:

5.Start the BOOTP daemon by typing the command /usr/etc/BOOTPd. The MIL-4711H will broadcast BOOTP packets and will obtain a response from the server and will use the IP address specified in /etc/BOOTP file.

To set the IP Address with BOOTP on a HP/UX system:

1.Login as root on the system and start SAM, the System Administration Tool, by entering sam at the command line.
