Using packet papture software like Wireshark is a useful troubleshooting technique that can be used to examine packets and gather details to help find the root of a problem. In my previous post , I talked a little bit about how to use Wireshark and walked through some steps to run a simple packet capture from a PC. This time, I'm going to go a bit deeper into the how to for doing packet captures.
One of the features I've seen in newer small network routers is the inclusion
of a packet sniffer/capture/trace tool within the diagnostic menus of the device.
Routers I've recently tested with this functionality include the SonicWall TZ190W ,
D-Link DFLCPG310 , and Netgear's newly released
FVX538 and FVS336G .
In each case, these devices have the ability to capture packets on a specific
WAN port and/or on the LAN interface. Some of these routers have more sophisticated
filtering capabilities than the other, but they all seem to have the same basic
functionality of capturing packets.
In the final chapter, we find out about wireless and VPN and whether our hero gets the girl.
In Part 2, David Hawkins maintains peace and harmony between heavy and light parts of the network.
Atheros today announced that it is sampling a low-cost six port 10/100
Ethernet switch chip to key customers.
The company said the AR8216 will allow it to provide networking customers
with "all of the major silicon required for complete wire-to-wireless router
solutions". Atheros chose to produce a 10/100 switch instead of a gigabit
Ethernet version because it believes that is where the volume will be in the near
term.

InterWorking Labs today announced Mini Maxwell , a portable, low-cost network emulator.
The product is a Layer 2 network emulator with the ability to apply packet impairments including drop/lose, duplicate, delay and reordering to five user-defined traffic "bands" in both transmit and receive directions. A variety of packet filters can be applied including IPv4 source/destination address, Layer 3 source/destination port, protocol, MAC address and more.
The Mini Maxwell measures 6" x 6" x 1" weighs less than two pounds and is controlled via a web interface. Two 10/100 Ethernet ports are available for traffic and one for control.
The product is available now for $1,499 direct from InternetWorking Labs' website .
Readers share their stories about building their own home networks. We look at three systems, one of which takes an especially unique approach to component integration.
HomePlug "Turbo" technology prominently touts that it delivers data at "up to 85 Mbps" rates. But Tim Higgins found that the usual games that manufacturers play with throughput claims has been taken to new lows with these products.
Setting up a small LAN isn't always easy for the newbie. David Strom looks at two products that try and somewhat succeed at easing the pain of getting a small LAN up and running.
Tim Higgins is back with Part 2 of his new home network adventures. This time it's all about the connections - wall plates and patch panels, that is.
Designing a system to distribute communications and electronic entertainment services around a new home can be a daunting task. But with the right approach, you don't have to be a master of the home networking universe to do it, and you might even have fun! Tim Higgins recently did just that.
Chris Dickens' series has so far shown you how to organize a smooth-running LAN party and get it powered properly. This time he offers tips on choosing networking gear, installing it and handling the problems that come with the territory.
You can't have a LAN Party without a LAN and you shouldn't set up your party's LAN before reading the latest installment of our How To. Chris Dickens returns to step you through what it takes to set up a fast, robust LAN that can handle plenty of fraggin'.
