--------------------------------------------------------------------------------
Добрый день.
Появилась такая проблема: после апгрейда (даунгрейда) системы с 4.8Stable до
4.8Release-p13 и установки свежего pptpd сервера (PoPToP v1.1.4-b3) у
клиентов вместо соединения с сервером стало выскакивать следующее сообщение:
"Локальный компьютер не поддерживает требуемый тип шифрования", причем с
теми же настройками на другой тачке (4.8Stable + PoPToP v1.1.3) - все ок...
(причем в конфиг pptpd.conf - даже не лазил, все есть в /etc/ppp/ppp.conf)
less /etc/ppp.conf
default:
set log Phase Chat LCP IPCP CCP tun command
set mtu 1496
set timeout 0
set reconnect 3 0
enable lqr
set lqrperiod 5
disable ipv6cp
disable pap
deny pap
set dns Ip-dns1 Ip-dns2
accept dns
enable tcpmssfixup
# Запрещаем сжатие CCP/Predictor type 1
disable pred1
deny pred1
pptp:
enable MSChapV2
set mppe * stateless
set ifaddr 10.10.0.1 10.10.0.2-10.10.1.254 255.255.255.255
В логах при включенном дебаге пишет вот что:

И еще пара маленьких вопросов:
Вот устанавливаю в /etc/ppp/ppp.conf mtu = 1496
а на деле вижу такое:
tun3: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1498
inet 10.10.0.1 --> 212.220.xxx.150 netmask 0xffffffff
Opened by PID 8932
tun5: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1494
inet 10.10.0.1 --> 212.220.xxx.155 netmask 0xffffffff
Opened by PID 9803
И еще - кто то говорил, что mpd починили насчет связки WinXP+mpd (Unix) =
trouble _MTU - поставил свежий mpd-3.15 - а там все по-старому.
mtu у WinXP выставляется 1396 ...
