/PPPOESERV i386
>Description:
We want to install a WLAN on our campus. The decision for authentication is pppoe.
We started pppoed with following option:
/usr/libexec/pppoed -dF -e "/usr/sbin/ppp -direct server" xl1
For the ppp we use the following configuration (/etc/ppp/ppp.conf):
default:
set device PPPoE:xl1
set speed sync
set mtu 1492
set mru 1492
server:
set cd
set login
enable proxy
set ifaddr 192.168.35.1
set radius /etc/radius.conf
enable PAP
After starting the pppoed everything is fine. clients are able to connect and communicate with the network.
But a windows pppoe-test-programm shows the dark side - kernel panic:
Fatal trap 12: page fault while in kernel mode
fault virtaul address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc19ca36d
stack pointer = 0x10:0xcc2cbee0
frame pointer = 0x10:0xcc2cbef4
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 165 (ppp)
interrupt mask =
trap number = 12
panic: page fault
syncing disk... 15 15
The trigger for this phenomenon was Poet 1.6 on a Windows-client (pppoe-test-programm):

Second test-part brought the server to crash.
