Network Troubleshooting Cookbook in Linux servers?

[networkloser]

There are various network issues that are pretty common.
Things like "No route to host"....bla bla.
Is there a cookbook for troubleshooting these issues in Linux? The problem is it's not possible exactly to tell what's happening sometimes. So, having a cookbook reference (example bash cookbook by oreilly) would help imo. Troubleshooting guide kinda thing.

This also depends on what's doing the routing for the Linux box. Most of the time, it's everything out the one network interface and it's a vendor device that's doing routing and switching work. But if the Linux box has to do the layer 2/ layer 3 work, then checking those iptables is going to be needed to resolve issues...
