General question about writting packet to sent via Ethernet to WARP

We'd like to try sending controlled packet instead of random broadcast or ping packet to the WARP board through the ethernet interface.

I wonder if there is any Matlab module or other software that would let me initialize/specific a custom packet to be sent via HOST PC ethernet to the WARP's EMAC. In a way that we can specify the destination address, content of the packet and the socket type.

Thanks in advance.

Re: General question about writting packet to sent via Ethernet to WARP

There are a few tools that make this easy:

1) ping can generate traffic with arbitrary packet sizes and rates; on Unix systems, the -i and -s flags enable this

2) iperf is a network performance measurement tool that also allows arbitrary rates and sizes using either UDP or TCP

3) The free TCP/UDP/IP toolbox for MATLAB lets you create and send arbitrary packets from the MATLAB command line. We use this toolbox for our PHY prototyping framework.
