ubuntu 16.04のVPN PPTPは機能しませんか?

this answerのように詳細を記入します。しかし、接続しようとすると、次のようになります。

VPN Connection Failed '...because the VPN service stopped'

次の手順を使用して、ターミナルからpptp VPNサーバーとクライアントを構成できます。

VPNサーバーのセットアップ:

VPNサーバーとクライアントパッケージをインストールして更新します。

$ Sudo apt-get install pptpd ppp pptp-linux

サーバー用に4つのファイルを設定する必要があります:

  • /etc/pptpd.conf
  • / etc/ppp/pptpd-options
  • / etc/ppp/options
  • / etc/chat-secrets)

/ etc/pptpd.conf:

 option /etc/ppp/pptpd-options
logwtmp
localip 192.168.23.20 
 remoteip 192.168.23.30-39 

/ etc/ppp/pptpd-options:

 name pptpd 
 refuse-pap 
 refuse-chap 
 refuse-mschap 
 require-mschap-v​​2 
 require-mppe- 128 
 proxyarp 
 nodefaultroute 
 lock 
 nobsdcomp 
 noipx ## IPX 
 mtu 1490 ##は不要かもしれませんLinuxクライアントの切断
 mru 1490 ##は、Linuxクライアントの切断を助ける

/ etc/ppp/options:

lock

/ etc/ppp/chap-secrets:

#CHAPを使用した認証の秘密
#クライアントサーバーの秘密IPアドレス
 
 [ユーザー名] pptpd [userpass] * 

([username]と[userpass]は角括弧なしのエントリです。)

今すぐサーバーを再起動:

$ Sudo service pptpd restart

VPNクライアントのセットアップ:

4つの構成ファイルが関係します:

  • / etc/ppp/peers/myvpn
  • /etc/ppp/options.pptp
  • / etc/ppp/chap-secrets
  • /etc/ppp/ip-up.local

/ etc/ppp/peers/myvpn:

#ブラケットパラメータをVPNサーバーのホスト名およびVPNユーザーに置き換えます。
リモート名myvpn 
 linkname myvpn 
 ipparam myvpn 
 pty "pptp [vpnサーバー] --nolaunchpppd "
 name [username] 
 usepeerdns 
 require-mppe 
 refuse-eap 
 noauth 
 
#pptp-linuxパッケージ
 file /etc/ppp/options.pptp
からデフォルトを採用

/ etc/ppp/options.pptp:

 lock 
 noauth 
 refuse-pap 
 refuse-eap 
 refuse-chap 
 refuse-mschap 
 nobsdcomp 
 nodeflate 

/ etc/ppp/chap-secrets:

#CHAPを使用した認証の秘密
#クライアントサーバーの秘密IPアドレス
ユーザー名myvpnパスワード* 

/ etc/ppp/ip-up.local:

#!/ bin/sh 
 network = `echo $ IPREMOTE | awk -F \。 '{print $ 1 "。" $ 2 "。" $ 3 ".0/24"}' `
 route add -net $ network $ IFNAME 

VPNクライアントを次のもので接続します

$ Sudo pon myvpn

VPN接続を終了するには:

$ Sudo poff myvpn

@ L.D.Jamesソリューションから変更

Ubuntu 16.04

VPNクライアントのセットアップ:

4つの構成ファイルが含まれます:

  • / etc/ppp/peers/myvpn
  • /etc/ppp/options.pptp
  • / etc/ppp/chap-secrets
  • /etc/ppp/ip-up.local

/ etc/ppp/peers/myvpn:

#ブラケットパラメータをVPNサーバーのホスト名およびVPNユーザーに置き換えます。
リモート名myvpn 
 linkname myvpn 
 ipparam myvpn 
 pty "pptp 1.2.3.4 --nolaunchpppd --loglevel 0 "
 lock 
 nodeflate 
 name LoginName 
 usepeerdns 
 require-mppe 
 noauth 
 require-mppe-128 
  1. 1.2.3.4をVPNホストIPアドレスに変更します。そして
  2. LoginNameをログイン名に変更します

/ etc/ppp/options.pptp:

 lock 
 noauth 
 refuse-pap 
 refuse-eap 
 refuse-chap 
 refuse-mschap 
 nobsdcomp 
 nodeflate 
 name LoginName 
 require-mppe-128 
 ipparam myvpn 
  1. LoginNameをログイン名に変更します

/ etc/ppp/chap-secrets:

#CHAPを使用した認証の秘密
#クライアントサーバーの秘密IPアドレス
 LoginName myvpn LoginPassword * 
  1. LoginNameをログイン名に変更します
  2. LoginPasswordをログインパスワードに変更します

/ etc/ppp/ip-up.local:

#!/ bin/sh 
 network = `echo $ IPREMOTE | awk -F \。 '{print $ 1 "。" $ 2 "。" $ 3 ".0/24"}' `
 route add -net $ network $ IFNAME 

でVPNクライアントを起動します:

$ Sudo pon vicomvpn dump logfd 2 nodetach
pppd options in effect:
nodetach        # (from command line)
logfd 2     # (from command line)

local  IP address 192.168.1.142
remote IP address 192.168.1.1

VPN接続を終了するには:

$ Sudo poff myvpn
