[RP-PPPoE] rp-pppoe.so in kernel mode

[Adrian Ban]

On Debian GNU Linux for example:

root at RouterFW:/home/adrian# dpkg -l | grep ppp
ii  ppp                               2.4.5-5.2 amd64        
Point-to-Point Protocol (PPP) - daemon
ii  ppp-dev                           2.4.5-5.2 all          
Point-to-Point Protocol (PPP) - development files
root at RouterFW:/home/adrian#

Which has already the rp-pppoe plugin compiled:

root at RouterFW:/home/adrian# ls  -1 /usr/lib/pppd/2.4.5/
minconn.so
openl2tp.so
passprompt.so
passwordfd.so
pppoatm.so
pppol2tp.so
radattr.so
radius.so
radrealms.so
rp-pppoe.so
winbind.so
root at RouterFW:/home/adrian#

As you can see already has the rp-pppoe.so.
So far so good.

Now:
root at RouterFW:/opt/pppoe/rp-pppoe-3.11/src# PPPD=/usr/sbin/pppd 
./configure --enable-plugin
checking for gcc... gcc
...
checking for id... /usr/bin/id
checking for Linux 2.4.X kernel-mode PPPoE support... yes
checking packing order of bit fields... reversed
...
On this platform, the following targets will be built:
pppoe pppoe-server pppoe-sniff pppoe-relay rp-pppoe.so
Type 'make' to compile the software.
root at RouterFW:/opt/pppoe/rp-pppoe-3.11-debian/src# make

If you are using Debian package builder change the line:

         test -f src/Makefile || (cd src && PPPD=/usr/sbin/pppd ./configure)

in

         test -f src/Makefile || (cd src && PPPD=/usr/sbin/pppd 
./configure --enable-plugin)

And do a:

dpkg-buildpackage -us -uc

root at RouterFW:/opt/pppoe/rp-pppoe-3.11/src# ./pppoe-server -h
Usage: ./pppoe-server [options]
Options:
    -I if_name     -- Specify interface (default eth0.)
..
    -k             -- Use kernel-mode PPPoE.
..
    -h             -- Print usage information.

After this start the pppoe-server with:

/usr/sbin/pppoe-server -k -L 10.0.0.1 -R 10.0.0.10 -N 256 -o 0 -I eth2  
-O /etc/ppp/pppoe-server-options

Which will listen to interface eth2 with a maximum 256 sessions and 
offset starting from 0.
If you start another pppoe-server for another interface be careful to 
set offest starting from 256 not from 0 like first one.

I've attached an option file.

Hope this will help you.
