As with virtually all documentation, the writers fail to provide ALL the information needed by someone unfamiliar with the subject. In this case there is insufficient said about any config files except ppp.conf. eg what happens with r.conf, what IP addresses are to be assigned to the two NICs, what goes in resolv.conf / ppp.linkup / etc ?? According to the official docs, all that needs to be added to the kernel config file is "options NETGRAPH" ... however that is a sure way to get error messages on boot "module_register: module netgraph already exists! linker_file_sysinit "netgraph.ko" failed to register! 17" I found what looks like the solution to these messages at freebsddiary.org "The above netgraph message can be eliminated by adding the following to your kernel file, eliminating the need to load the netgraph ether module, which you will need for pppoe to function anyway. NETGRAPH_ETHER In other words, these are the options that you will need to obviate the need to load any modules. options NETGRAPH options NETGRAPH_ETHER options NETGRAPH_PPPOE options NETGRAPH_SOCKET That sounds like FUD to me; I've never had Netgraph problems except for: * when I was using it as a KLD, and I forgot to rebuild the module when I updated my kernel. * when it was broken briefly in -current due to SMPng locking changes If you have problems with it, you should be talking to the developers. I'm using PPPoE right now, and all it took to configure was to kldload the relevant modules or add them to my kernel configuration (and set up the PPP information per the documentation). > OpenBSD doesn't use it (possibly a security related issue) I doubt it; probably just because no-one has yet ported NetGraph to OpenBSD. Whilst OpenBSD mailing list archives are a dogs breakfast, I stumbled across a posting from Brian Somers that suggested the OpenBSD developers didn't want netgraph. There wasn't any further explanation but it sorta sounded like it was a security issue.
