Spex uses a digi for communication to serial device at cass.
In hilo, we test using hilodigi1.

  	 hilodigi's (hilo)IP:  128.171.110.211
   spexdig's (summit) IP: 128.171.165.79

For centos 4.4, I need to do 'yum install rarpd', and the deamon is 'rarpd'.
The following example was perform using centos 4.4.

1. Edit /etc/ethers and add the appropriate information:
	0:40:9d:21:fb:bd  hilodigi 

2. Check the hosts table to make sure the host/IP is defined.

3. Run RARP daemon.

   # rarpd -A -v -d
    (the linux deamon has no feedback, tun on port server and ping to see that it worked).
	 use 'tail -f /var/log/messages' to see when the rarpd issued the IP.

4. Turn on the PortServer.

5. Is it alive? Note that the RARP setup is reset when the power is recycled on the PortServer.

# ping 128.171.110.211 
128.171.110.211 is alive

6. Telnet in to complete the configuration

# telnet 128.171.110.211
Connected to 128.171.110.211.
Escape character is '^]'.
