- Agent and System Manager cannot communicate with each other
- Agent complains that idds has not been enabled, yet lsdev shows /dev/idds is present
- Agent does not start on system boot
- Agent halts abnormally, leaving ids_* files and message queues
- Agent host appears to hang and/or you see message disk full
- Agent needs further troubleshooting
- Agent does not start after installation

1. Create the X.509 Certificates
To create a certificate for the HP-UX HIDS System Manager process, first generate the ids
user locally on the HP-UX HIDS administration system. Only then can the certificates for
each of the agent nodes be signed by the HP-UX HIDS administration system. The
administration system holds the Root Certification Authority (Root CA) that endorses all
other certificates.
a. On the administration system, log in as follows:
$su - ids
b. Change your directory to /opt/ids/bin, as follows:
$cd /opt/ids/bin
c. Generate the following administration keys:
$IDS_genAdminKeys install
This creates the Root CA and the administration certificate. They are stored in the /etc/
opt/ids/certs/admin directory. The keyword install is optional.
If you need to regenerate the administration certificate later, for example, if the current
certificate has expired without invalidating the agent certificates you make in step d,
enter the command again with the update option. For example:
$IDS_genAdminKeys update
If you do not use the update option, the command also recreates the Root CA, making
the existing agent certificates no longer trusted by the administration system. Repeat
step d and steps 2 and 3.
Following is an example of the installation process run on the administration host,
adminsys:
$ IDS_genAdminKeys
==> Be sure to run this script on the IDS
Administration host.

************************************************************
* Successfully created certificates for IDS
Root CA and for
* the HP-UX Host IDS System Manager.
* Certificate public keys are valid for 700
days and are
* 1024 bits in size.
*
* Now you need to create keys for each of the
hosts on which
* the Agent software is installed by running
the script
* 'IDS_genAgentCerts'.

d. Generate the keys for each agent, one bundle of keys per agent system, as follows:
