A daemon might do some ocnfiguration etc. but you don't want it near the data. Examples of link-level protocols in netgraph modules include ppp (multilink ppp), frame relay, 802.1x, (or is that 11x) bluetooth, the cisco bonding (ng_nge from Bill Paul, though it doesn't really use netgraph properly) and the netgraph atm stack. > > On a side note, is there anything netgraph can't solve :) not good at level3 protocols as far as I can see. > > --don (don@sandvine.com www.sandvine.com) > To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
