Synchronizing Errata and Packages Directly via RHN451. Connects over SSL to central RHN Servers, authenticates itself as an RHN Satellite, and triggersan export of RHN data — unless a local mount point for RHN-exported data is specified, in whichcase no connection is necessary. Refer to Section 6.3.2, “Synchronizing Errata and Packages viaLocal Media” for an explanation.2. Examines the export and identifies differences between the RHN Satellite data set and theexported RHN data set. For a particular channel, the following information is analyzed:• Channel metadata• Metadata of all packages in that channel• Metadata for all Errata that affect that channelNoteAll analysis is performed on the RHN Satellite; the central RHN Servers deliver onlyan export of its channel information and remain ignorant of any details regarding theRHN Satellite.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, animport 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 RHNFor customers who want to sync data as frequently as possible and who can initiate connectionsoutside of their own environments, the satellite sync can be run over the Internet through SSL. This isthe default setting for the satellite sync script. For example:satellite-sync -c rhel-i386-as-3This 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 channelson the Satellite will be refreshed.6.3.2. Synchronizing Errata and Packages via Local MediaFor customers who cannot connect their Satellite directly to RHN, Red Hat recommends downloadingChannel Content ISOs to a separate, Internet-connected system and then transferring them to theSatellite. Refer to Section 6.2.2.1, “Preparing Channel Content ISOs” for instructions on downloadingthe ISOs. For ease of import, we recommend that the data be copied from media directly into acommon repository through a command such as the following:cp -rv /mnt/cdrom/* /var/rhn-sat-sync/Then, the following command:
