To create a host-based firewall on Linux, the appropriate command line application to use is **iptables**.

### Explanation:
1. **iptables**: This is a powerful utility that allows a system administrator to configure the IP packet filter rules of the Linux kernel firewall. It provides a framework for filtering and manipulating network traffic on a host.

2. **fwtables**: This is a newer framework that is designed to replace iptables, but it may not be available in all distributions or be the default for host-based setups.

3. **conntrack**: This tool is used for tracking the state of network connections. It is not a firewall creation tool but rather a utility that interacts with connection tracking in iptables.

In summary, when it comes to creating a host-based firewall, **iptables** is the most widely used and supported command line application.
