Wireshark and EtherIP Packets

Sat, 04 Jun 2011 00:00:00 +0000

I got a call from our Systems and Security guys today to talk about a Wireshark capture they had done from a user VLAN. They had noticed two frames that were destined for some seemingly random host in the same network as they were in, but the source and destination IP addresses reported by Wireshark made no sense. The frames were from a web server to an IP address on our wireless network. The web server is on the other side of the firewall, and the wireless network is on the other side of the controller; there was no reason at all that a packet with that source and destination would show up here.

I’m way behind in talking about this, but Jeremy Stretch over at Packetlife.net has a community lab that is free to use. This is a great resource for those of us who are too poor to have their own physical devices for Cisco studies. All you need is an account on the site and a sense of community.

There are two labs to reserve, and each contains a firewall, routers, and switches. This is plenty of stuff to get your feet wet with the gear, let you research some functionality that Cisco promised is great, and to lab out something you’re looking to implement. The lab is offered for free, but Jeremy is giving his time and money for this lab. I think it would be a great idea to drop a few dollars to him via his donate link if you use his stuff. If you’re a regular user and don’t donate, I ask that you do a moral inventory on yourself so you might see just how bad you are being.
