4.1 Enabling or Disabling Slave Synchronization Support for a Spacewalk Server

By default, a Spacewalk server is configured so that it can act as a master server. Any slave servers that you configure for the master server will be able to synchronize from it. The following steps are not usually necessary unless you want to disable this feature on a Spacewalk server that acts only as a slave server.

Enable or disable support for slave synchronization on a Spacewalk server as follows:

To disable ISS support, edit /etc/rhn/rhn.conf and set the value of disable_iss to 1:
```
disable_iss=1
```
To enable ISS support, edit /etc/rhn/rhn.conf and set the value of disable_iss to 0:
```
disable_iss=0
```
Restart the httpd service.
For Oracle Linux 6, type the following command:
```
# service httpd restart
```
For Oracle Linux 7, type the following command:
```
# systemctl restart httpd
```
