[-- Attachment #1 --] For a small SoC based system, I use a highly customised static kernel and build the system via NanoBSD with no kernel modules. Tyring to track down some network issues with recent CURRENT I figured out, that when using the ppp client to connect via modem to the ISP and there is no options NETGRAPH_ETHER options NETGRAPH_PPPOE in the kernel configuration, the resulting system fails to establish a ppp session. The man page states, that a netgraph node is established, but as hard as I look, I can not find any(!) information in the man pages what options are necessary/optional to provide the correct module statically. The same is for many other NETGRAPH_XXX features. Starting from man page "man 4 netgraph", section "SEE ALSO", I started tweaking the kernel with NETGRAPH_XXX, i.e. ng_vlan -> NETGRAPH_VLAN until the compiler bails out with an error, for instance ng_car -> NETGRAPH_CAR. I tried to find out what options cover which netgraph module but there is - right, nothing I can find on a direct route. Since netgraph isn't so brand new (I guess ~ 2000 from the PDFs I found on the network), there must be some documentation other than "reading the source code". Please give me some hints where to find the entry point for the appropriate documented options for netgraph modules. Obviously, some ng_xxx modules are prerequisite for some services to work properly, as ppp - but I can't find any hints for "options NETGRAPH_ETHER" or "options NETGRAPH_PPPOE" in the manpages (looked at ppp, pppoed). Thanks in advance, kind regards Oliver [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- iLUEARMKAB0WIQQZVZMzAtwC2T/86TrS528fyFhYlAUCWWvRIgAKCRDS528fyFhY lKVuAf9ttIIywpjg0Vnrj6Awh5DlAwLOnB54ovZ9PguWbDdq/iFqQTc6hx3Th02g dyn/9wFlvJ0kF7bCSG/qeuKCnmyZAf4otoEFsVPS4374Efq5wqQimilXas0+QVkb KiSfuL6gROt7KJ2ql08HkDTGTB6CmN7M8FU3Rjo9WgSC6aWchFjk =88Sv -----END PGP SIGNATURE-----help
