Appendix B. Host Management Without Goferd
From Satellite 6.2.11 onward, errata and package management via remote execution is available using a yum plugin. This allows the goferd service daemon to be disabled, thereby reducing memory and CPU load on content hosts.
The yum plugin is included with the katello-host-tools. This shipped with the Satellite 6.2.11 client update.
B.1. Prerequisites Copy linkLink copied to clipboard!
The following must be made on all content hosts to allow host management by remote execution.
- Ensure katello-agent is installed on the content host by following Section 3.5.3, “Installing the Katello Agent”.
Stop the goferd service:
systemctl stop goferd.service
# systemctl stop goferd.serviceCopy to Clipboard Copied! Toggle word wrap Toggle overflow Disable the goferd service:

B.2. Configuring Host Management Without Goferd as the System Default Copy linkLink copied to clipboard!
These steps configure host management to use remote execution as the system default for future package deployments.
To Configure Host Management Without Goferd as the System Default:
- Log in to the Satellite web UI.
- Navigate to Administer > Settings.
- Select the Content tab.
- Set the Use remote execution by default parameter to Yes.
The Satellite server now uses host management by remote execution instead of goferd.
B.3. Limitations with Hammer Copy linkLink copied to clipboard!
The following applies if you are using the hammer command to push errata. The hammer command is dependent on goferd to manage errata on content hosts. As a workaround, use Satellite’s remote execution feature to apply errata.
To Use Hammer Remote Execution Commands:
For example, perform a yum -y update on host123.example.org:
