ITO Installation Problems with Multi-homed Hosts

Installation of the ITO agent software includes distributing a

nodeinfo

file to the managed nodes. This file contains information about the
managed node, such as the parameter

OPC_IP_ADDRESS

, used by the

management server to identify the managed node in communication.
The

nodeinfo

file is automatically updated when the administrator

modifies the IP-address using the

Modify Node

window.

You need to follow these instructions when you specify an IP-address
using the

opcmsg(1)

command to send messages to the management

server.

Use the

netstat(1)

command to check if a host is multi-homed. An

example of the HP-UX output follows:

#

netstat -r

Routing tables

Problem

The installation script

inst.sh (1M)

prompts for a password in an

endless loop, even if the correct password has been specified.

Description

If no

.rhosts

entry is available for root on the managed node, the ITO

installation will prompt for the root password. If you have specified the
correct password and the message

rexec: Lost connection

is displayed, then possibly the management server is not yet known on
the managed node.

Solution

Add the management server entry to

/etc/hosts

and/or update your

Name Server if one is used.
