To fine-tune your network protocol these tools are invaluable TCP optimize - The TCP Optimizer is a free, easy Windows program that provides an intuitive interface for tuning and optimizing your Internet connection http://www.speedguide.net/files/TCPOptimizer.exe TCP port half open - Half-open limit fix is a program designed to change the maximum number of concurrent half-open outbound TCP connections (connection attempts) in the Windows system tcpip.sys file. http://half-open.com/Half-open_limit_fix_4.1.exe
Mpegmaster, thank you for your post, some very useful stuff there. Another tip... If you are a Windows user, go for Windows 7 Release Candidate which is on a year's free trial from Microsoft. No HO limit changes needed, very fast and stable even on most older hardware. Better TCP stack, newer congestion control algorithm built in. Compulsive Nagging Mode has been removed. If you're running Vista especially on a laptop, you'll find it such an improvement you'll probably have a heart attack. See also TCP-Z for a useful utility.

Network Exploration & Security Audits http://nmap.org/ :thumbup: Nmap - Free Security Scanner For Network Exploration & Security Audits.:thumbups: Nmap ("Network Mapper") is a free and open source (license) utility for network exploration or 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, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are avalable for Linux, Windows, and Mac OS X. http://bitaudit.com/ :thumbup: BitAudit: The Tool You Don't Want Anti-Pirates To Have | TorrentFreakoke: bitAudit is a free security tool that logs key interactions in a bittorrent swarm.

ipv6mon - by... SI6 Networks' Address Monitoring Daemon http://www.si6networks.com/tools/ipv6mon/ ipv6mon is a tool meant for monitoring IPv6 address usage on a local network. It is meant to be particularly useful in networks that employ IPv6 Stateless Address Auto-Configuration (as opposed to DHCPv6), where address assignment is decentralized and there is no central server that records which IPv6 addresses have been assigned to which nodes during which period of time. ipv6mon employs active probing to discover IPv6 addresses in use, and determine whether such addresses remain active.
