Функцията Point-to-point (MPPE) encryption е активна..

Здравейте!

Имам проблем с настройката на VPN Ubuntu 16.04. Просто отказва да се свърже по какъвто и да е повод. Предположих, че може да съм объркал конфигурацията но след толкова опити и неуспех се съмнявам проблема да е в това.

tail -f /var/log/syslog

ми дава:

Това което съм опитъл до момента е да спра IPv6 протокола както и да създам файл

/etc/modules-load.d/netfilter.conf

със следното съдържание

nf_nat_pptp
nf_conntrack_pptp
nf_conntrack_proto_gre

Re-install на Network-manager също не помогна.

Не, все още правя безуспещни опити...

И какъв е извода?

lsmod | grep ppp_mppe 

Нямаш вдигнат модула /или компилиран в кърнала.Може и да не ти трябва, но пък си сложил чафката

modprobe ppp_mppe и пробвай  с lsmod | grep ppp_mppe ако се появи тествай впн-а.

До колкото подразбирам явно има проблем с тази версия на Убунту и pptp.

drbrcho@drbrcho:~$ modprobe ppp_mppe
drbrcho@drbrcho:~$ lsmod | grep ppp_mppe
ppp_mppe               16384  0

PPP MPPE Compression module registered Аз това пак не го видях при теб.

lsmod | grep ppp_mppe 
lsmod | grep ppp_async 
lsmod | grep crc_ccitt

Това се получава..

root@drbrcho:/home/drbrcho# lsmod | grep ppp_async
ppp_async              20480  0

…
До колкото разбирам в Убунту са преименували /var/log/messages/ на /var/log/syslog/
…

Хе-хе Никсдорф връщаш ме само няколко години назад, когато и аз не знаех, за какво служат тези неща. Не е изненадващо, това са регистри ползвани от администраторите. Но всеки е администратор на собствената си машина и рано или късно опира до тяѝ.

С две думи, не е вярно, че са преименували съобщенията в сислог. Това са две различни неща. Първото е съобщения давани от ядрото, второто е регистър осигурен от централният регистратор в системата. Към него може да се свърже всяка услуга. Много от демоните там пренасочват изходите си за грешка.

Да възможно е информация да се дублира в двата регистъра с различно оформление, но тя стига по различни канали там.


п.п. Ъ-ъ-ъ да. Не съм голям специалист по VPN, но с nm никой не може да ти помогне. Това е пьотеринщина, която си прави, каквото иска. Щом си успял да се свържеш през нея дай курбан за здраве и остави някоя лепта в кварталната църква.

Заключението не го направих сам разбира се. Чичко гугъл така каза по-точно straight outta ubuntu 

The system log typically contains the greatest deal of information by default about your Ubuntu system. It is located at /var/log/syslog, and may contain information other logs do not. Consult the System Log when you can't locate the desired log information in another log. It also contains everything that used to be in /var/log/messages.

ЕДИТ: Някой друг network manager който мога да използвам ?

Опитах и по твоя начин колега... уви без успех.
До колкото разбирам в Убунту са преименували /var/log/messages/ на /var/log/syslog/ и това което копирах в началото на темата ми излиза само (освен ако аз бъркам нещо...)
 Едит: Проблема май е бил в мене относно даване на правилното инфо

Здравейте колеги!!!
Опитвам се от два дни да се свържа към vpn мрежата на работа.
Та ubuntu 16.04
Следвах тези стъпки:

Steps:

    1.Install “network-manager-pptp” package and dependencies
    2.Reboot computer (this is important, nothing will work until you reboot)
    3.Click on Network Manager icon, go to “VPN Connections” then “Configure VPN”
    4.Click “Add”, select “PPTP”, then click “Create”
    5.Fill in the following information:



VPN SETTINGS:
-- Add/Edit Main Dialog --
Connection name: [VPN Connection] *
Gateway: [vpn.example.com]
User name: [username] **
-- Advanced button --
PAP: UNcheck
CHAP: UNcheck
MSCHAP: UNcheck
MSCHAPv2: check
EAP: UNcheck
Use Point-to-Point Encryption (MPPE): check
Security: 128-bit
Allow stateful encryption: UNcheck
Allow BSD data compression: check
Allow Deflate data compression: check
Use TCP header compression: check
Send PPP echo packets: UNcheck

Пробвах всякъкви различни authentication методи без успех. Само един единствен път успях да се свържа с Ubuntu когато бях вързан за wi-fi мрежата на работа.
С Windows 7 нямам никъкви проблеми да се свържа от където и да е било.

sudo tail -f /var/log/syslog

Благодаря за помоща!
