5.3 Validating RPM signatures (optional)
For security reasons, you might want to verify that the RPMs in the Insight Control for Linux ISO
image are properly signed by HP before installing them.
The RPMs for HP Insight Control for Linux are digitally signed with a private key. You have the
option to use the public key shipped on the Insight Control for Linux ISO image to validate and
verify the RPMs. Because you have downloaded the ISO from the Software download site, and
this site is SSL secured by HP, you can ultimately trust that the public key on the ISO is indeed from
HP.
Although this verification process is optional for you, it ensures that HP is the creator of the code
and that the code has not been modified since it was signed.
Determining which public keys are installed
To determine which public keys are installed, enter the following command:
# rpm -q gpg-pubkey
Where gpg-pubkey is the public key.
Alternatively, you can use the rpm -qi command to show more details about the certificates.
Installing the public key
To install the public key from an Insight Control for Linux ISO image, follow these steps:
1. Log in to the CMS with the superuser account (root).
2. Create a temporary mount point:
# mkdir /mnt/dirname
3. Mount the ISO image for HP Insight Control for Linux:
# mount -o loop IC-LX_release.iso /mnt/dirname
Where IC-LX_release.iso is the ISO image for HP Insight Control for Linux; the name of
your image will differ.
4. Navigate to the HP/public_keys directory on the mount point:
# cd /mnt/dirname/HP/public_keys
5. Install the public key:
# rpm --import rpm-hpPublicKey.pub
NOTE: If you do not install the HP public key, the install.sh installation script outputs the
messages shown in Section 9.1.3 (page 57). It is safe to ignore these messages, but you can avoid
them if you install the HP public key.
