ATA over Ethernet (''AoE'') is a network protocol designed for accessing ATA storage devices over Ethernet networks.

This "How To" explains the process of using ATA over Ethernet protocol to intercept ATA commands from a Linux system (called Linux client) using [[Wireshark]] for diagnostic and testing purposes.

== Linux server - Linux client configuration ==

First, make sure that Linux server and Linux client are connected to the same network and can exchange packets with each other.

=== Server configuration ===

Make sure that your server has [http://packages.debian.org/en/lenny/vblade ''vblade''] tool installed. Then run the following command:

# vblade 0 0 eth0 /dev/sda

Where:
* eth0 - your network interface;
* /dev/sda - a block device you want to be accessible through a network.

=== Client configuration ===

Make sure that your Linux client has [http://packages.debian.org/en/lenny/aoetools ''aoe tools''] installed. Then run the following command:

# modprobe aoe

Make sure your vblade device is available on the client by running:

# aoe-stat

The following block devices would be available:

* /dev/etherd/e0.0 - the whole disk (corresponds to /dev/sda on the server);
* /dev/etherd/e0.0p1 - first partition on the disk (corresponds to /dev/sda1 on the server);
* /dev/etherd/e0.0p2 - second partition on the disk (corresponds to /dev/sda2 on the server).

== Intercepting ATA commands ==

Launch [[Wireshark]] on a client and start a capture on ''eth0''. You can apply the following display filter to analyse AoE packets only:

eth.type == 0x88a2

Here is a screenshot of [[grml]] client running in VirtualBox:
