I have two VM's running on Ubuntu box.Their name and IP addresses are give below.

nas 192.168.129.153
home_user 192.168.129.152

I establish a ppp connection between the two machines

#nas (server)
sudo pppd noauth local lock defaultroute persist nodetach 10.1.1.2:10.1.1.3 pty “nc -l 3333”

#home_user(client)
sudo pppd noauth local lock nodetach passive pty “nc 192.168.129.153 3333”


Once I do the above I can see a ppp connection established between the two machines (from ifconfig )

#nas (server)

ppp0 Link encap:Point-to-Point Protocol
inet addr:10.1.1.2 P-t-P:10.1.1.3 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1

TX packets:5 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:78 (78.0 B) TX bytes:72 (72.0 B)

#home_user (client)

ppp0 Link encap:Point-to-Point Protocol
inet addr:10.1.1.3 P-t-P:10.1.1.2 Mask:255.255.255.255

TX packets:5 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:72 (72.0 B) TX bytes:78 (78.0 B)


My next aim is to use PPPoE for transport.I install pppoe package on the server

sudo apt-get install pppoe

sudo pppoe-server -I eth0 -L 192.168.129.153 -R 192.168.129.152 -O /etc/ppp/options

I have edited the options file to enable chap and pap authentication.I have also edited chap and pap secret files.

Now my question how do I use the ppp daemon pppd to connect to the server above?
It seems that I have to use the /usr/lib/ppp/version/rp-pppoe.so (part of ppp daemon).How do I make the ppp daemon act as a pppoe client that supports authentication?Any help is appreciated.

Add to the pppd options, either :

plugin rp-pppoe.so ethX

or :

pty "/usr/sbin/pppoe -I ethX"
