Configuring a Loopback System
On a non-networked system (no IP address) or for testing purposes, you may want to set
up the administration system in a loopback arrangement. This allows only a locally
running agent to communicate with the System Manager on the same system; no other
agent systems can be monitored.
To configure a loopback system
Step 1. On the administration system, become user ids:
$ su - ids
Step 2. Edit the agent configuration file; for example:
$ vi /etc/opt/ids/ids.cf
Step 3. Set the value of IDS_LISTEN_IFACE to:
IDS_LISTEN_IFACE 127.0.0.1
Step 4. Set the value of REMOTEHOST in ids.cf to:
REMOTEHOST 127.00.1
Step 5. Edit the System Manager script; for example:
$ vi /opt/ids/bin/idsgui
Step 6. Set the value of INTERFACE in idsgui to:
INTERFACE=127.0.0.1
Step 7. Start the System Manager (see “Starting the HP-UX HIDS System Manager” on
page 46).
Step 8. On the Host Manager screen, set up the administration system as an agent system,
using 127.0.0.1 as its IP address (see “Adding a New Host Manually” on page 87 or
“Modifying a Host” on page 91).
