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.
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.
