Networking Tools

netstat

• -i interface config info (use ifconfig -a on Linux for verbose interface info)
• -a all ports(listening and non-listening)
• -l all listening ports
• -t listening TCP ports
• -p display PID and program names
• -c it's like watch
• -rn list routes but don't resolve ip
• -n numeric ports

* `apt` cannot be followed by module name directory, have to use `name` option
* `import_playbook` is not a task, do not put under tasks
* Don't use `copy`, it is slow, use `synchronize` instead
* `shell` doesn't handle symlink chdir correctly, it's gonna chdir you to resolved path.

Django-REST-Framework

Serializers
	* Notice that we're using hyperlinked relations in this case, with HyperlinkedModelSerializer. You can also use primary key and various other relationships, but hyperlinking is good RESTful design
	
	* HyperlinkedModelSerializer:
		class UserSerializer(serializers.HyperlinkedModelSerializer):
			class Meta:
				model = User
				fields = ('url', 'username', 'email', 'groups')
