Troubleshoot network problems via network analysis or sniffing

If you are a systems administrator, network engineer, or security engineer, you constantly field questions like "Why is the network slow?" "Why is my computer acting strange?" or "Why can't I get to the shared drive?" Thus begins the complex and sometimes tedious or painful journey of troubleshooting. In this sample chapter from Ethereal Packet Sniffing, study network analysis or sniffing, the process of capturing network traffic and inspecting it closely to determine what is happening on the network. Chapter coverage includes:

• What is network analysis and sniffing?
• Who uses network analysis?
• How does network analysis work?
• Detecting sniffers
• Protecting against sniffers
• Network analysis and policy
