--Sig_/jCUKN6pPgzU2BtZuu4XsnS3 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable For a small SoC based system, I use a highly customised static kernel and b= uild 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=20 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/optiona= l to provide the correct module statically. The same is for many other NETGRAPH_XXX features. Starting from man page "m= an 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 in= stance 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 p= roperly, as ppp - but I can't find any hints for "options NETGRAPH_ETHER" or "options N= ETGRAPH_PPPOE" in the manpages (looked at ppp, pppoed).=20 Thanks in advance, kind regards Oliver --Sig_/jCUKN6pPgzU2BtZuu4XsnS3 Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iLUEARMKAB0WIQQZVZMzAtwC2T/86TrS528fyFhYlAUCWWvRIgAKCRDS528fyFhY lKVuAf9ttIIywpjg0Vnrj6Awh5DlAwLOnB54ovZ9PguWbDdq/iFqQTc6hx3Th02g dyn/9wFlvJ0kF7bCSG/qeuKCnmyZAf4otoEFsVPS4374Efq5wqQimilXas0+QVkb KiSfuL6gROt7KJ2ql08HkDTGTB6CmN7M8FU3Rjo9WgSC6aWchFjk =88Sv -----END PGP SIGNATURE----- --Sig_/jCUKN6pPgzU2BtZuu4XsnS3--
