Hi Leonardo,

This is not a direct answer and I need to ask you from the first step but: 1. What version of "NetFPGA base" do you have? The simplest way is to check "CHANGES" file in your netfpga installed directory.
2. I assume you have followed the following wiki for the installation:
http://www.openflow.org/wk/index.php/CentOS_NetFPGA_Install
3. Did you try the openflow regression test mentioned above to make sure your installation was successful? 4. When you mentioned running the commands, can you show me what exactly did you run (with arguments)?

Thank you,
Tatsuya Yabe

Hello everybody.
I am realizing some experiments with OpenFlow, but I feel that I am
doing something incorrect.
I wanted to use my NetFPGA cube as an OpenFlow Switch with 2 ports,
and trying to communicate with a pc with this configuration:
NetFPGA cube: controller localhost + switch port nf2c3 linked with
eth0 of the PC host, and nf2c2 connected with eth1 of the cube;
Pc host: eth0 connected with nf2c3.

This way, I run all the commands (controller, ofdatapath, ofprotocol)
and I wanted to ping the eth1 with the eth0 of pc host and vice versa.
Addresses are:
PC -> eth0:192.168.2.10
CUBE-> eht1:192.168.2.5

The problem is that when I try to ping each other, it says destination
unreachable.
Am I doing something wrong with this configuration? May be the other
"terminal" to ping can't stay in the same place of the switch, and so
I need to add another host?
Thank you.
