The Paranoid Penguin Connection Another reason I wrote this book has to do with the fact that I write the monthly "Paranoid Penguin" security column in Linux Journal Magazine. Several years ago, I realized that all my pieces so far had something in common: each was about a different aspect of building bastion hosts with Linux.By then, the column had gained a certain amount of notoriety, and I realized that there was enough interest in this subject to warrant an entire book on Linux bastion hosts. Linux Journal generously granted me permission to adapt my columns for such a book, and under the foolish belief that writing one would amount mainly to knitting the columns together, updating them, and adding one or two new topics, I proposed this book to O'Reilly, and they accepted.Predictably, the book project was exponentially more work than I could have imagined. I spent a great deal of effort re-researching and expanding all of it, including retesting all examples and procedures. I added entire (lengthy) chapters on topics I hadn't yet covered at all in the magazine, and I more than doubled the size and scope of others. In short, I allowed this to become The Book That Ate My Life in the hope of reducing the number of ugly security surprises in my readers' lives. |
