## 8. Troubleshooting

There are several troubleshooting techniques that I used in the course of this project. I would expect people attempting this to be familiar with most or all of them. Here are a few:

1. tcpdump is your friend when attempting to prove that your traffic really is going over the VPN.
2. ldd is very helpful in finding out what libraries are missing when you have to install a package by hand.
3. qemu or another emulator is priceless when you don't wish to waste a bunch of physical CDs or the time it takes to burn and boot them.
