Ethereal Packet Sniffing is the first book in Jay Beale’s new Open Source Security Series with Syngress. Ethereal is full of helpful tips and clear discussions that benefit newbies and wizards alike. The key to the new material is Ethereal’s development, from 0.2 in July 1998 to 0.10.3 this year. The many improvements lend themselves to the sort of explanations found in Ethereal. For example, my favorite material involved filters. For instance, I learned new ways to manipulate the packet search and display capabilities.”]
