NetWorx

NetWorx is a simple and free, yet powerful tool that helps you objectively evaluate your bandwidth situation. You can use it to collect bandwidth usage data and measure the speed of your Internet or any other network connection. NetWorx can help you identify possible sources of network problems, ensure that you do not exceed the bandwidth limits specified by your ISP, or track down suspicious network activity characteristic of Trojan horses and hacker attacks.

Right-click the NetWorx system tray icon (as shown in the image below) to bring up the program's menu. This menu lets you control the utility.

Wireshark

Wireshark (also known as Ethereal) is a network protocol analyzer that enables you to capture and examine data from a live network or from a capture file on disk. You can interactively browse the capture data and view summary and detail information for each packet. Wireshark has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session. It can read capture files from tcpdump (libpcap), NAI Sniffer (compressed and uncompressed), Sniffer Pro, NetXray, snoop, Shomiti Surveyor, AIX s iptrace, Microsoft Network Monitor, Novell s LANalyzer, RADCOM s WAN/LAN Analyzer, HP-UX nettl, ISDN4BSD, Cisco Secure IDS iplog, the pppd log (pppdump-format), and the AG Group s/Wildpacket Etherpeek. It can also read traces made from Lucent/Ascend WAN routers and Toshiba ISDN routers. Any of these files can be compressed with gzip and Wireshark will decompress them on the fly.

DynDNS Update Client

What is an update client?

An update client is a computer application or a feature in your router that keeps your hostname's IP address up-to-date. The update client periodically checks your network's IP address; if it sees that your IP address has changed, it sends (updates) the new IP address to your hostname in your DynDNS.com account.

Why do I need an update client?

If you're like most DynDNS.com customers, you have a dynamic IP address which changes periodically (monthly, weekly or even daily). This can make it difficult or impossible to connect to services at home, like remote desktop or FTP.

Using an update client with your Dynamic DNS or Custom DNS hostname allows you to make sure you can always reach your home network, because it makes sure that your hostname is always up-to-date with the latest IP address. The update client runs in the background, so once you have it properly configured you don't have to worry about it; you only need to remember your hostname to reach your files and services.

Which update clients can I use?

You can either use the update client in your router or download a software client to run on your computer. We highly recommend using software clients since they tend to be more reliable than many of the update clients used in routers.
