Issue with userspace pppoe-server (PADS not sent)

[murugav86]

Hi,

I am using CentOS release 5.4 (Final) in my x86_64 machine (Linux 2.6.18-164.el5 #1 SMP).
I try to connect my client machine (user: aluppp) with userspace pppoe-server.
pppoe-server fails to send out PADS frames back to client.

=============================
Client cfg (pppd/2.4.5/rp-pppoe.so):
=============================
lcp-echo-interval 50
user aluppp
password alutesyt
mtu 1492
idle 0
maxconnect 0


=============================
Server side config:
=============================
# cat /etc/ppp/options
lock
crtscts
nobsdcomp
nodeflate
nopcomp

# cat /etc/ppp/pppoe-server-options
# PPP options for the PPPoE server
# LIC: GPL
auth
require-chap
login
default-mru
default-asyncmap
lcp-echo-interval 50
lcp-echo-failure 5
ms-dns a.b.c.d
noipdefault
noipx
nodefaultroute
noproxyarp
noktune
netmask 255.255.255.255
logfile /var/log/ppp/pppd.log

# cat /etc/ppp/chap-secrets
# Secrets for authentication using CHAP
# client server secret IP addresses
"eagle" * "eaglepw" 192.168.100.3
"test" * "testpass" 192.168.100.11
"aluppp" * "alutesyt" 192.168.100.33

#pppoe-server -I eth0 -F
//cmd success - fails in PADR

# ifconfig

Moreover, no logs were logged in /var/log/ppp/pppd.log, while
tail -f /var/log/messages display only pppoe server termination message
(pppoe-server[16280]: Terminating on signal 2 -- killing all PPPoE sessions)

I have attached wireshark capture snapshot.
Please some one help to resolve this issue.

Thanks in advance
