HP-UX IPSec version A.02.00 Administrator's Guide

Configuring HP-UX IPSec
Using ipsec_config
Chapter 3 65
Multihomed Nodes with Private Interfaces If the local system is
multihomed with one public IP interface and one or more private IP
interfaces, you may want to secure only the one public IP interface. In
this case, you can set the default source parameter value to the address
of the public IP interface in the HostPolicy-Defaults, GWPolicy-Defaults,
and TunnelPolicy-Defaults sections of the profile file.
Dynamic Configuration Updates
The ipsec_config utility dynamically updates the configuration
database. If HP-UX IPSec is running, ipsec_config also updates the
runtime IPSec policy database, and runtime IKE configuration data
(IKE policies and authentication records).
Dynamic Deletions
If you delete an object while HP-UX IPSec is running, HP-UX IPSec
deletes it from its runtime database. If you delete an IPSec policy,
HP-UX IPSec deletes any associated IPSec/QM SAs. If you delete an IKE
policy, HP-UX deletes any associated ISAKMP/MM SAs. IPSec/QM SAs
negotiated using the ISAKMP/MM SAs may continue to operate, but IKE
peers will be unable to send control messages for the affected IPSec/QM
SAs.
nocommit Argument
The nocommit argument validates entries but does not update the
configuration and runtime databases. The nocommit argument is illegal
inside batch files (you cannot specify the nocommit argument as part of a
statement inside a batch file). You can specify the nocommit argument as
part of the ipsec_config batch command line and ipsec_config will
apply it to all entries in the batch file. Refer to the ipsec_config (1M)
manpage for more information.
