我必须连接到 Cisco Meraki VPN。

  • 我正在使用全新安装的 Kubuntu 18.04 LTS。
  • 我得到了一个公共 IP、一个 VPN 用户、它的密码和一个预共享密钥。
  • 我打开网络管理器并创建了一个新的 VPN，选择第 2 层隧道协议 (L2TP) -与 L2TP VPN 服务器兼容-。我在各自的字段中填写了数据。

我能够在 16.04 年前连接到这些类型的 VPN，但是当我连接到这个时，我得到了错误，因为我是这个主题的新手，所以我不能很好地理解错误消息。这是系统日志（XXX.XXX.XXX.XXX 表示我必须连接到的公共 IP）：

然后我尝试连接xl2tpd停止的服务。无法绑定到端口 1701的消息消失了，但出现了新的错误，实际上我认为结果更糟，因为我什至无法在任何消息中看到我必须连接到的公共 IP。

我也尝试填写 IPsec 设置的Phase 1和Phase 2字段，正如我在几个论坛中阅读的那样，但我什至不知道该写什么，我只是复制了其他答案，所以这是废话。

谁能帮我理解发生了什么？

我试图在服务器中进行备份，但出现错误：

pg_dump command not found

我认为如果您安装了 postgres，它就可以工作。我必须做什么才能安装此命令？我不认为这是可能的apt-get或能力。

我是这个主题的新手，有人告诉我从运行 Kubuntu 13.10 的计算机连接到 VPN。我还获得了要连接的服务器 (vpn.server_x.com:81)、一个用户及其密码。我拥有的最后数据是这是 Linux 上的 openconnect。

我阅读了几个教程并尝试使用vpnc,openvpn和pptp-linux，因为我不知道我必须使用哪个。我总是出错，阅读 /var/log/syslog 也不是很有用，因为我不知道我是否在做愚蠢的事情。

例如，一开始我认为我必须使用vpnc，所以我安装了它，然后通过网络设置创建了一个新连接，但它要求我输入网关、用户名、用户密码、组名和组密码。在我写的网关vpn.server_x.com:81中，但我没有足够的数据来填写其余部分。

我是否在创建正确的 VPN 连接？
