Reviews

[Michael Bond · Rating 4 out of 5]

Good coverage of a topic that system administrators usually don't have the time or inclination to learn.

It covers variations among various Linux distributions. Debugging is covered in pretty good detail.

It might have been nice to have a few more examples of complete configurations.
