> Is there an easy way for me to send packets to a ethernet interface? Certainly the easiest way is to use one of the supported higher level protocols. If you need to generate ethernet frames for some random ethernet/IEEE 802.3 protocol, then you ought to look at perhaps using bpf(4) as a way to send packets. According to the man page, this is supported on ethernet and slip interfaces. I believe there's also a way to do this with raw sockets. > On VMS, we had the capability of issuing a qio to the ethernet interface so > I am wondering if we have an ioctl or something that would allow me > to talk the ethernet interface. Any more details on the sort of traffic you're trying to generate? That might help narrow down a good approach to puruse. louie
