openvpn工具箱使用教程

發布時間:2022-12-30 11:29:39

⑴ Centos7使用docker搭建openvpn

執行完命令後可在目錄 /data/openvpn 中看到相應的配置文件;

執行過程中需要先設置ca密碼(如123456),Common Name可不設置直接按回車繼續,接著需要輸入ca密碼更新密鑰庫以及生成crl文件;

其中 openvpn-client 為自定義名稱,生成的過程需要輸入ca密碼;

注意 openvpn-client 名稱需與第三步生成時命名一致,此時生成的配置文件 openvpn-client.ovpn 即可用於客戶端連接;

需要注意防火牆規則,其中1194為udp埠,可在其他機器上通過nc命令測試是否可連接

修改配置文件 /etc/sysconfig/iptables ,在*filter中的COMMIT命令前增加以下配置

重啟iptables, systemctl restart iptables ,如未生效需重啟docker

安裝好客戶端後,導入openvpn客戶端配置文件即可,ccip.cc檢查當前ip;

⑵ 如何使用OpenVPN和PrivacyIDEA搭建雙因素認證的遠程接入

第一種,使用PAM的privacyidea_pam.py模塊。OpneVPN使用PAM認證,PAM調用privacyidea_pam.py模塊和PrivacyIDEA做驗證。
第二種,直接集成OpenVPN和FreeRADIUS。OpenVPN使用radius認證,FreeRADIUS向PrivacyIDEA驗證。
第三種,在OpenVPN中使用RADIUS的PAM模塊。

⑶ Openvpn構建線上區域網

參考大佬鏈接,搭建沒有問題,在調試階段不對 CentOS 7 搭建OpenVPN伺服器_Centos7搭建vpn | abcdocker運維博客 (i4t.com)

每一個登陸的VPN客戶端需要有一個證書,每個證書在同一時刻只可以一個客戶端連接(可以修改配置文件)

生成過程比較慢,在此期間不要去中斷它

啟動成功會多一個 tun0的虛擬網卡

要導出對應的client端key 根證書 ca.crt , client.crt , client.key , ta.key

安裝client http://down.i4t.com/openvpn-install-2.4.7-I606-Win10.exe

配置如下

如果一直鏈接不上請確認

我是在安全組卡了很久,這兩只是client 與服務端鏈接成功,說明我們搭建openvpn已經完成了
這時已經可以直接登錄到server端;

到這我們搭建openvpn已經完成了
這時已經可以直接登錄到server端,但是無法登錄區域網內的其他機器,因為server端未開轉發
開轉發還會遇到安全組問題,因此要使用SNAT替換訪問的ip

參考鏈接 基礎知識Iptables - (jianshu.com)

工具使用tcpmp 監聽網卡 參考鏈接 tcpmp詳細教程 - (jianshu.com)
#監聽tun0網卡上訪問 192.168.10.118數據
tcpmp -n -i tun0 host 192.168.10.118

在客戶端ping ,發現有去無會,一看ip都是10.8.x.x 肯定無法過安全組,因此用iptables替換ip,整個服務就可用了

⑷ openvpn設置clientopenwrt

方法如下:
1、將OP的路由通過無線client模式連接到上級無線路由器(inter)端,網路介面中的wwan(無線client介面)使用DHCP或者PPPOE認證到上級路由,設置完畢保存應用。
2、將OP的路由通過無線client模式鏈接到上級無線路由器(inter)端,無線設置中將介面選擇為lan,進行橋接,網路介面中的br-lan關閉DHCP配置,防火牆轉發開啟、出入開啟請自行測試。

⑸ 如何在Windows環境下安裝並配置OpenVPN

Step 1 OpenVPN安裝配置
1.1 下載openvpn 並安裝
· 下載openvpn-2.0.5-gui-1.0.3版,地址 http://openvpn.se/files/install_packages/openvpn-2.0.5-gui-1.0.3-install.exe,安裝。(例如:安裝到F:\OPENVPN目錄下,下文舉例都用此目錄)
· 安裝完成後生成一個新網卡,並在網路連接里出現本地連接[X],把tcp/ip屬性改成手動配置,192.168.10.1(根據實際情況更改) ,255.255.255.0,其餘不填。
1.2 生成證書
· 修改F:\OpenVPN\easy-rsa\vars.bat.sample的以下部分
CODE:
set HOME=%ProgramFiles%\OpenVPN\easy-rsa
set KEY_COUNTRY=US
set KEY_PROVINCE=CA
set KEY_CITY=SanFrancisco
set KEY_ORG=FortFunston
set [email protected]
(請根據自身情況修改)改為
CODE:
set HOME=F:\OpenVPN\easy-rsa
set KEY_COUNTRY=CN
set KEY_PROVINCE=Hubei
set KEY_CITY=Wuhan
set KEY_ORG=51NB
set [email protected]
· 生成證書
o OpenVPN 有兩種安全模式,一種基於使用 RSA 證書和密鑰的 SSL/TLS,一種使用預先分享的靜態密鑰。本文採用SSL/TLS 模式。TLS模式的優點是安全,而且便於管理用戶。默認情況下證書和用戶是一對一的,多個用戶使用同一證書會被踢出。

生成多個客戶端密鑰,執行build-key client1 …… build-key xyz。

復制證書文件
剛才生成的證書文件在F:\OpenVPN\easy-rsa\keys下,伺服器端需要的文件為ca.crt,dh1024.pem,server.crt,server.key ,客戶端需要的文件為:ca.crt client.crt client.key(xxx.crt xxx.key),配置.ovpn文件時需要用到。
1.3 配置server.ovpn文件
· 在\OpenVPN\config目錄下創建server.ovpn文件將ca.crt,dh1024.pem,server.crt,server.key復制到F:\OpenVPN\config目錄下
· 伺服器端文件示例:
server.ovpn
CODE:

port 1198
proto tcp-server
dev tun
server 192.168.10.0 255.255.255.0
keepalive 20 180
ca ca.crt

⑹ open-vpn參數參考

1、open-vpn路由設置
主要由 route-nopull、vpn_gateway、net_gateway 三個參數決定
route-nopull :當客戶端加入這個參數後,openvpn 連接後不會添加路由,也就是不會有任何網路請求走 openvpn.
vpn_gateway:指定需要走vpn的路由;
net_gateway:指定不需要走vpn的路由; max-routes 參數表示可以添加路由的條數,默認只允許添加100條路由,如果少於100條路由可不加這個參數.
route-nopull
route 139.9.114.177 255.255.255.255 vpn_gateway
route 192.168.6.0 255.255.255.0 vpn_gateway
route 192.168.5.0 255.255.255.0 vpn_gateway
route 192.168.1.0 255.255.255.0 net_gateway

⑺ 使用花生殼怎樣搭建Openvpn

Openvpn是虛擬專用通道,簡單來說就是一個虛擬區域網。Openvpn部署在內網,但是Openvpn 伺服器端的網路並沒有公網ip地址,要怎樣才能在外網連接呢?沒有固定公網IP,需要藉助一些網路輔助實現VPN的搭建和訪問,類似應用有花生殼、nat123、dnspod等等。通過使用花生殼主機映射功能,達到外網連接Openvpn,詳細操作過程如下:
1.搭建Openvpn伺服器端和訪問端.

2.修改OpenVPN伺服器端的server.ovpn文件,將proto udp 更改為proto tcp;
3.在服務端安裝並設置埠映射.
應用名稱:Openvpn(可自定義)。
內網主機:填寫伺服器內網的ip地址或者計算機名稱(不支持中文);選擇主機映射。
4.在訪問端上安裝花生殼訪問者,然後填寫域名,點擊診斷。
5.修改Openvpn 客戶端的client文件,將proto udp更改為tcp;將remote my-server-1 1194更改為remote 域名(設置埠映射的域名)1194。運行Openvpn 客戶端,出現綠色代表連接成功。
6.搭建Openvpn成功後,可以檢驗一下。就以搭建一個遠程桌面為例:
伺服器端獲取虛擬ip地址為10.0.0.1,客戶端獲取虛擬ip地址為10.0.0.6。在訪問端開啟遠程桌面,在伺服器端點擊運行——mstsc——輸入客戶端虛擬ip地址10.0.0.6 進行連接,出現如下界面代表連接成功。

⑼ Windows 7上OpenVPN怎麼設置使用

從問題來看只是安裝了OpenVPN,但是沒有對其進行配置。此外OpenVPN分伺服器端和客戶端(安裝程序一樣,只是配置文件不一樣)。
OpenVPN客戶端不是安裝了就能用,需要伺服器端才能起作用。比如OpenVPN客戶端裝在Windows 7筆記本上,伺服器端用的是Windows2003 VPS。
需要進行的操作為:
(1)對伺服器端進行設置
(2)在伺服器端並生成相應的文件(包括server.ovpn, ca.crt, client.key, client.crt),確保配置正確後啟動伺服器端。
(3)復制客戶端需要的文件(ca.crt, client.key, client.crt)到客戶端,製作client.ovpn,啟動客戶端連接伺服器端。

⑽ Windows 7上OpenVPN怎麼設置使用

將解壓出來的文件夾config內的配置文件覆蓋openvpn安裝目錄下的config內的文件。
在config文件夾下有一個文本mypass.txt,請將VPN帳號和密碼輸入:第一行VPN用戶名,第二行VPN密碼。
上面的搞定後,點擊桌面上的「OpenVPN GUI」【Vista或Win 7/8必須右鍵,以管理員身份運行】右下角會出現一個像電腦的小圖標,右鍵就可選擇VPN伺服器。
