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 rx0, 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): http://home.t-online.de/home/hanewin/poet-e.htm Second test-part brought the server to crash. -----dmesg-output Copyright (c) 1992-2000 The FreeBSD Project.
