# LIC: GPLRP-PPPoE now supports kernel-mode PPPoE on Linux kernels 2.4 or newer.However, the default "./go" build procedure does not make kernel-modesupport.Here's what you need to do:0) Make sure you are running kernel 2.4 or newer on the machine youwill build rp-pppoe on.  You must have the following kernelconfiguration settings:	CONFIG_PPP=m          or CONFIG_PPP=y	CONFIG_PPP_ASYNC=m    or CONFIG_PPP_ASYNC=y	CONFIG_PPP_SYNC_TTY=m or CONFIG_PPP_SYNC_TTY=y	CONFIG_PPP_DEFLATE=m  or CONFIG_PPP_DEFLATE=y	CONFIG_PPP_BSDCOMP=m  or CONFIG_PPP_BSDCOMP=y	CONFIG_PPPOE=m        or CONFIG_PPPOE=y	CONFIG_N_HDLC=m       or CONFIG_N_HDLC=y	CONFIG_UNIX98_PTYS=yYou also need a /dev/ppp file:	mknod --mode=664 /dev/ppp c 108 0You might want to add these lines to /etc/modules.conf:	alias char-major-108 ppp_generic	alias tty-ldisc-3 ppp_async	alias tty-ldisc-13 n_hdlc	alias tty-ldisc-14 ppp_synctty	alias net-pf-24 pppoe1) If you are running pppd older than 2.4.0, check out the latestversion of the PPP software from the CVS repository at cvs.samba.org.Here's how to do this:	cvs -d :pserver:cvs@pserver.samba.org:/cvsroot login	# When prompted for a password, type "cvs"	# Change to the directory in which you want to store the PPP source	# code.	cd /path/to/checked/out/sources	# Check out the source	cvs -z5 -d :pserver:cvs@pserver.samba.org:/cvsroot co pppIf you are running pppd 2.4.0 or newer, and have the pppd developmentheaders installed, you can skip steps 1 and 2.2) The source gets checked out into a subdirectory called ppp.  Ifthe source ends up in /path/to/checked/out/sources/ppp, then callthat path $PPPDIR.Build and install the checked-out ppp code according to its instructions.3) Unpack rp-pppoe.4) In the rp-pppoe directory, change to src/ and type:	./configure --enable-plugin=$PPPDIRwhere $PPPDIR, of course, refers to the checked-out "ppp" directoryfrom cvs.samba.org.If you didn't check out the PPP software from cvs.samba.org, use:	./configure --enable-pluginThis will work if the header pppd/pppd.h is located in /usr/includeor /usr/local/include.4) Type make; make install5) Edit /etc/ppp/pppoe.conf to include this line:	LINUX_PLUGIN=/etc/ppp/plugins/rp-pppoe.soAfter that, pppoe-start should use kernel-mode PPPoE.The rp-pppoe.so plugin adds the following command-line options to pppd:ethXXX                          -- Use interface ethXXX as Ethernet interfacebrXXX                           -- Use interface brXXX as Ethernet interfacenic-XXXX                        -- Use interface XXXX as the Ethernet interfacerp_pppoe_service SERVICE_NAME   -- Specify desired service namerp_pppoe_ac NAME                -- Specify desired access concentrator namerp_pppoe_verbose 0|1            -- Print names of access concentratorsrp_pppoe_sess nnnn:aa:bb:cc:dd:ee:ff -- Attach to existing session 'nnnn'                                on AC with Ethernet address aa:bb:cc:dd:ee:ff                                This skips the discovery phase.--David F.
