Avoid cheap network adapters

"If you need high throughput and low impact on your server, you are better off buying a quality network adapter. Unfortunately, some name-brand adapters are not much better than the cheap adapters, and some potentially good adapters do not have accurate documentation available to write good drivers. Gigabit adapters often perform better than 10Mbps/100Mbps adapters, even when used on slower speed networks, due to superior buffering." (emphasis added)

Security scanner

'Nmap (Network Mapper) is a free utility for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, which operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.'
