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

[Palasamudram, Chaitra (NSN - IN/Bangalore)]

Hi Adrian,

One more point in my environment is : I will not be directly running on the same platform. I am using a cross compiler to compile on some build server. My actual target or the machine is different. 

Would it make any difference for building the plugin. Because in the below procedure you are mentioning the path for the PPPD binary. 

Thanks again.

Regards
Chaitra

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.
