Chapter 6. Importing and Synchronizing

allowed_iss_slaves=

By default, no slave Satellites are specified to sync from the master server, so you must enter the
hostname of each slave Satellite server, separated by commas. For example:

allowed_iss_slaves=slave1.satellite.example.org,slave2.satellite.example.org

Once you finished configuring the 

rhn.conf

 file, restart the 

httpd

 service by issuing the following

command:

service httpd restart

6.4.3. Configuring the Slave RHN Satellite Servers

To configure RHN Satellite slave servers for Inter-Satellite Sync, ensure that you have the ORG-SSL
certificate from your master RHN Satellite server so you can securely transfer content. This can be
downloaded over http from the 

/pub/

 directory of any Satellite. The file is called 

RHN-ORG-TRUSTED-

SSL-CERT

, but can be renamed and placed anywhere on the slave Satellite, such as the 

/usr/

share/rhn/

 directory.

For information about SSL configuration for use with RHN Satellite, refer to Chapter 3, "SSL
Infrastructure" in the 

RHN Satellite Client Configuration Guide

Once the SSL certificate is placed on the slave server, you can see the list of channels available
to sync from the master Satellite server by running the following command (replacing the

master.satellite.example.com

 with the hostname of the master Satellite server):

satellite-sync --iss-parent=master.satellite.example.com --ca-cert=/usr/share/rhn/RHN-ORG-
TRUSTED-SSL-CERT --list-channels

This command lists both Red Hat Network Hosted channels as well as any custom channels available
on the master Satellite server.

6.5. Using Inter-Satellite Sync

Now that Inter-Satellite Sync is configured, you can now use it to synchronize channels from the
master Satellite to the slave servers.

On the slave servers, configure the Master server hostname and SSL certificate file path in the
following lines of the 

/etc/rhn/rhn.conf

 file:

iss_parent      = master.satellite.domain.com
iss_ca_chain    = /usr/share/rhn/RHN-ORG-TRUSTED-SSL-CERT

Then run the 

satellite-sync

 command by typing:

satellite-sync -c your-channel
