I'm trying to play around with netgraph(4) for the first time and there seem to be some aspects of it that haven't "clicked" in my head just yet.
What I want to do seems like it should be pretty easy. I want to send some packets through a UDP tunnel. There is an /usr/share/examples/netgraph/udp.tunnel file that is close to what I want, but not quite. I want to send packets that have been divert(4)ed to the tunnel. I can make my two ng_ksocket(8) nodes via the ngctl(8) interface, + mkpeer ksocket d0 inet/dgram/udp + name d0 udptun + msg d0 bind inet/192.168.64.70:10000 + msg d0 connect inet/192.168.64.50:10000 + mkpeer ksocket d1 inet/raw/divert + name d1 divtun + msg d1 bind inet/0.0.0.0:8668 But how do I then connect the two of them up? I assume that I use 'connect' within ngctl(8), but I haven't figured out what the arguments need to be with the documentation and examples I've found. The other thing I suspect I should be doing, is actually running the 'mkpeer' through the first node I create in ngctl(8), but I can't seem to get that to work, + mkpeer ksocket d0 inet/dgram/udp + name d0 udptun + msg d0 bind inet/192.168.64.70:10000 + msg d0 connect inet/192.168.64.50:10000 + mkpeer d0 ksocket d1 inet/raw/divert ngctl: send msg: Socket is already connected I think it is actually complaining about the hook between my ngctl node and the udptun node and not the creation of the divert socket? Basically, I think my conceptual problem is with the fact that you start with the ngctl(8) node in the middle of everything. How do I create my new nodes and get the ngctl(8) node out of the middle? -- Crist J.
