Configuring HP-UX IPSec

Step 10: Creating Backup Copies of the Batch File and Configuration Database

Step 10: Creating Backup Copies of the Batch File and Configuration Database

Create backup copies of your batch file and the configuration database files on removable media and store them in a secure place. The configuration database file path is:

•/var/adm/ipsec/config.db (IPSec policies, IKE policies, IKE authentication records, bypass entries)

Baltimore Configuration Files

Create backup copies of the following additional files if you are using Baltimore certificates:

•/var/adm/ipsec/cainfo.txt

•/var/adm/ipsec/.Bcerts

•/var/adm/ipsec/.Bsec

VeriSign Configuration Files

Create backup copies of the following additional files if you are using VeriSign certificates:

•/var/adm/ipsec/cainfo.txt

•/var/adm/ipsec/certs.txt

•/var/adm/ipsec/javabeans.txt
