Default Network Managers: Netplan (Ubuntu) vs. Wicked (OpenSUSE)

Default Network Managers: Netplan on Ubuntu vs. Wicked on openSUSE

In the world of Linux, where flexibility and configurability reign supreme, even network management tools vary significantly between distributions. Two notables among the myriad of network configuration managers available in the Linux ecosystem are Netplan and Wicked. While both tools serve the primary role of managing network settings, they originate from and are default options in different distributions—Netplan for Ubuntu and Wicked for openSUSE. Let’s dive deep into both, comparing their features, usage, and which might suit various user needs better.

What is Netplan?

Introduced in Ubuntu 17.10 as a default networking configuration tool, Netplan is a simple and easy-to-use utility to configure networks. It uses YAML (Yet Another Markup Language) configuration files to describe network interfaces and, as such, replaces the older, more traditional /etc/network/interfaces system.

Netplan processes these YAML files and generates configurations for a backend of your choice – either NetworkManager or systemd-networkd. This capability makes it highly versatile in both desktop and server environments. It posts simplicity and clear syntax, making it accessible for newcomers while still robust for professional use.

Pros of Netplan:

Simple YAML Syntax: Easy for humans to read and write.
Consistent Across Flavors: Works the same way across different Ubuntu flavors and derivatives.
Backend Agnostic: Users can switch between different network backends (NetworkManager or systemd-networkd) as they see fit.

Cons of Netplan:

Learning Curve: Some users accustomed to traditional Linux networking configurations might find the YAML syntax unusual or limiting.
Limited to Ubuntu and Its Derivatives: Not as universally usable across other Linux distributions.

What is Wicked?

Wicked is an open-source network management tool developed by the openSUSE community. It came as a part of the initiative to improve the network setup capabilities on both desktops and servers, particularly focusing on complex networking features like bridging, bonding, and virtual LANs. Wicked manages network configuration and can handle both static and dynamic (DHCP/DHCPv6) addresses.

It operates through a series of XML configuration files and a command-line interface (wicked), which offers a comprehensive set of commands to manage networking. Wicked is particularly proficient in environments that require elaborate network configurations and integrations.

Pros of Wicked:

Rich Feature Set: Supports advanced networking functions, including bridging, tunneling, and VLANs.
Integration with openSUSE: Tailored closely to work flawlessly within the openSUSE infrastructure.
Support for Legacy Scripts: Compatibility with older ifcfg scripts, which is a boon for users migrating from older systems or other SUSE-based distributions.

Cons of Wicked:

Complexity: More intricate than Netplan, which might deter newer users or simpler deployment needs.
Less Intuitive Command-Line Interface: The operations require a good understanding of its command structure and options.
Primarily for openSUSE: Like Netplan, its default integration is tied specifically to one family of Linux distributions.

Usage Scenarios

Ideal Use for Netplan:

Suitable for Ubuntu users or environments that need simple, clear network settings.
Enterprises deploying Ubuntu at scale, benefiting from YAML’s straightforward deployment and maintenance.

Ideal Use for Wicked:

Best for openSUSE users dealing with complex network setups.
Large openSUSE deployments or network admins who need to heavily customise their network configurations.

Conclusion

Choosing between Netplan and Wicked ultimately boils down to the user’s specific needs, environment, and distribution choice. Those who favor Ubuntu will find Netplan perfectly aligned with their systems, offering ease and simplicity. In contrast, users who handle more intricate network setups might lean towards Wicked on openSUSE for its robust capabilities and detailed configuration options.

Both network managers demonstrate the versatility and user-centric philosophy of the Linux ecosystem, catering to a diverse range of scenarios and preferences. Thus, whether you're a novice looking to set up a home network or an experienced system administrator managing enterprise infrastructure, understanding and selecting the right tool is pivotal to managing Linux network configurations effectively.
