Hi, I have a box with 5 old-style netgear (de) interfaces on it, one talking to the outside world, and 4 sending large quantities of data to a number of other machines on the same switch. At the moment, we're setting up a bunch of separate network addresses, one per card (de1-de4) and then use the application to bind to particular addresses when sending data to one machine. Now, what I'd like to do is to aggregate de1-de4 into a single virtual interface, with a simple round-robin setup, giving me a 400Mbit pipe to play with, and making the internal network setup a great deal easier. I first looked at Bill Paul's fec netgraph module, but this lacks a pure round-robin approach, and odd things happen when the data load is greater than a single interface. I also note that there are a number of places in the code where it's suggested that the code is not MP-safe. After a bit more investigation, I came across ng_one2many which appears to do exactly what I want, only it just refuses to work for me. The machine is running 4.3-STABLE as of a day or so, all appropriate modules have been loaded, viz: matrix 86# kldstat Id Refs Address Size Name 1 5 0xc0100000 1b143c kernel 2 1 0xc71d5000 c3000 vinum.ko 3 1 0xc72f8000 3000 ng_one2many.ko 4 2 0xc72fc000 8000 netgraph.ko 5 1 0xc7307000 3000 ng_socket.ko Yet when I try to perform the first part of the setup as documented in the manpage, I get the following: matrix 131# /usr/sbin/ngctl mkpeer de1: one2many upper one ngctl: send msg: No such file or directory matrix 132# and obviously, everything else fails to do anything. Any suggestions? I guess I could take the fec code, and rip it to bits with a pure round-robin approach, but that seems like reinventing the wheel given the existence of ng_one2many. What am I missing here?
