	=== NFS (Network File System) ===		== Setting up WLAN with Netplan ==
	==== Setting up an NFS Server ====		[https://netplan.io Netplan] is a network configuration system created by Canonical. YAML files are used to describe the desired network configurations. Netplan command-line tools are used to apply a given network configuration.
			<br />
			<br />
			To set up WLAN access using Netplan In the '''/etc/netplan''' folder, find the network configuration definition file (most likely '''50-cloud-init.yaml'''). Open the file in an editor. You should find an existing ethernet configuration:
			<pre class="code">
			network:
			ethernets:
			eth0:
			dhcp4: true
			optional: true
			version: 2
			</pre>
			where ''eth0'' is an example ethernet interface. To add a WiFi configuration, add the lines
			<pre class="code">
			wifis:
			<wlan>:
			optional: true
			access-points:
			"<ssid>":
			password: "<password>"
			dhcp4: true
			</pre>
			where ''<wlan>'' is usually ''wlan0'', and ''<ssid>'' and ''<password>'' need to be replaced with the actual WiFi SSID and password.
			<br/>
			<br/>
			As this is a YAML file, make sure that indentation levels are correct and only whitespace (no tab characters) is used.
			<br/>
			<br/>
			Now activate the new configuration via
			<pre class="terminal">
			sudo netplan generate
			sudo netplan apply
			</pre>
			and check with
			<pre class="terminal">
			ip a
			</pre>
			<br/>
			<br/>
