7. System administration#
This chapter covers low-level configuration tasks for technical administrators managing Nubus for UCS systems. It addresses the components that underpin every running system: the kernel, the boot process, network connectivity, and outbound proxy access.
- Kernel
Manage kernel packages, kernel versions, and kernel modules. This includes loading additional drivers, blacklisting unwanted modules, and integrating external drivers through Dynamic Kernel Module Support (DKMS). See Kernel.
- Boot manager
Configure GRUB, the boot manager in Nubus for UCS. Control the boot timeout, screen resolution, kernel options, and which kernel the system boots by default. See Boot manager.
- Network configuration
Configure network interfaces and advanced network setups such as bridging for virtual machines, bonding for failover redundancy, and VLANs for logical traffic separation. See Network configuration.
- Proxy settings
Route outbound traffic from command-line tools and Nubus for UCS update utilities through a proxy server using UCR variables. See Configure proxy settings through UCR variables.
