Synchronizing Errata and Packages Directly via RHN

3. After the analysis of the export data, any differences are imported into the RHN Satellite database.

Please note that importing new packages may take variable lengths of time. For a large update, an

import can take many hours.

The satellite-sync command can be used in two modes: via RHN and via local media.

6.3.1. Synchronizing Errata and Packages Directly via RHN

For customers who want to sync data as frequently as possible and who can initiate connections

outside of their own environments, the satellite sync can be run over the Internet through SSL. This is

the default setting for the satellite sync script. For example:

satellite-sync -c rhel-i386-as-3

This connects to central Red Hat Network Servers and performs the process described above.

Multiple channels can be included by repeating the option. If no channels are specified, all channels

on the Satellite will be refreshed.

6.3.2. Synchronizing Errata and Packages via Local Media

For customers who cannot connect their Satellite directly to RHN, Red Hat recommends downloading

Channel Content ISOs to a separate, Internet-connected system and then transferring them to the

Satellite. Refer to Section 6.2.2.1, “Preparing Channel Content ISOs” for instructions on downloading

the ISOs. For ease of import, we recommend that the data be copied from media directly into a

common repository through a command such as the following:

cp -rv /mnt/cdrom/* /var/rhn-sat-sync/

Then, the following command:

satellite-sync -c rhel-i386-as-3 --mount-point /var/rhn-sat-sync

This can be used to perform the sync process described above, using the dump files in /var/rhn-

sat-sync to perform the necessary comparisons and imports. See Section 6.2.3, “Running the

Import” for precise steps.

6.4. Inter-Satellite Sync

RHN Satellite 5.3 or greater supports synchronization between two Satellites. This synchronization,

also called Inter-Satellite Sync, allows administrators to simplify the process of coordinating content

from one RHN Satellite source to another or several others.

The following are the basic requirements for Inter-satellite Sync.

• At least two RHN Satellite 5.3 or greater servers

• At least one RHN Satellite populated with at least one channel

• Master RHN Satellite SSL certificate available on each of the slave RHN Satellites for secure

connection
