If You Have IP Connectivity Problems<br />

To check IP connectivity, do the following:<br />

1. Use the ping(1M) command on the management server:<br />

<strong>HP</strong>-UX<br />

# ping 193.1.4.1<br />

Solaris<br />

# ping -s 193.1.4.1<br />

2. Press Ctrl-C.<br />

If you receive a message similar to the following, you have a<br />

connectivity problem:<br />

PING 193.1.4.1: 64 byte packets<br />

----193.1.4.1 PING Statistics----<br />

3 packets transmitted, 0 packets received, 100% packet<br />

loss<br />

Problem<br />

If the ping(1M) command returns nothing, you have an IP connectivity<br />

problem.<br />

Managed Node<br />

jacko.deu.hp.com<br />

lan1:15.136.120.2<br />

lan0:193.1.1.1 lan1:15.136.120.1<br />

Management Server<br />

arthur.deu.hp.com<br />

lan0:194.1.1.1<br />

In this example, both the managed node and management server have<br />

two LAN interfaces. But they are connected only through the 15.136.120<br />

subnet. There is no route from the management server to the managed<br />

node through the 193.1.1 subnet, or from the managed node to the<br />

management server through the 194.1.1 subnet respectively.<br />
