Hi ppl.
Использовал ли кто на FreeBSD PPTP туннели?
Есть необходимость стандартными средствами Windows прокинуть VPN до
FreeBSD. Какие подводные камни меня ожидают?
Попробовав поднять туннель с Win получил сообщение о невозможности подобрать
протокол (я уже бросал сюда подробные логи этой попытки).
Сейчас решил попробовать поднять PPTP между двумя FreeBSD.
PPTP client - ver 1.0.2
PPTP server - ver 1.0.0
И вот получил следующее:
PPTP client:
/etc/ppp/ppp.conf
myserver:
set authname test
set authkey test
set timeout 0
set ifaddr 0 0
add 192.168.0.0/16 HISADDR
alias enable yes
После запуска pptp наблюдаю:
Mar 16 15:20:51 client (unknown)[76830]: log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:531]: Client connection established.
Mar 16 15:20:52 client ppp[76828]: Warning: No available tunnel devices found (Device busy)
Mar 16 15:20:52 client (unknown)[76830]: log[pptp_dispatch_ctrl_packet:pptp_ctrl.c:637]: Outgoing call established.
Mar 16 15:21:52 client (unknown)[76830]: log[pptp_read_some:pptp_ctrl.c:368]: read error: Connection reset by peer
Mar 16 15:21:52 client (unknown)[76830]: log[pptp_conn_close:pptp_ctrl.c:275]: Closing PPTP connection
Mar 16 15:21:52 client /kernel: pid 76830 (pptp), uid 0: exited on signal 10 (core dumped)
Как это нет доступных tunnel device?
tun0: flags=8151<UP,POINTOPOINT,RUNNING,PROMISC,MULTICAST> mtu 1480
inet x.x.x.x --> x.x.x.y netmask 0xffffffff
tun1: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
tun2: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
tun3: flags=8010<POINTOPOINT,MULTICAST> mtu 1500
На стороне PPTP сервера это выглядит так:
/etc/ppp/ppp.conf
pptp:
set speed sync
enable pap
enable chap
set dns w.w.w.w
accept dns

Может кто-то уже пробовал поднимать PPTP under FreeBSD - поделитесь
своими соображениями.
