Hello folks! I'm trying to use a Linux box as a packet traffic generator. It has two NICs configured with fixed IP addresses, 192.168.2.100/101. For testing purposes, I connected the two NICs to each other with a crossed network cable (hardware loopback). For what it's worth, they can both be pinged from the host and the ifconfig output looks fine.
Later, the crossed cable will be replaced by a radio link (which relates to the purpose of all this). To carry out the packet generation, I downloaded and built the iperf program (http://sourceforge.net/forum/forum.php?forum_id=808751). I'd like to sent stuff from .100 to .101 using the client and server instances of iperf in two console sessions and (later) monitor what's happening with tcpdump from a third session. For various reasons, it's not working. (I have successfully done it using two machines on either side of the radio link, which is the "standard" method.) Has anyone on the list done this (using iperf or something similar) using a single box with two NICs? Regards, Daniel P.S. I'll supply further background material if there is interest in this subject.
