使用 strongswan 进行公钥认证

使用 strongswan 进行公钥认证

我有两个系统 r1 和 r2，我想使用公钥认证通过 Strongswan 在它们之间建立 ESP 隧道。我已使用 openssl 在两个系统中生成公钥，分别存储在 r1-pub.pem 和 r2-pub.pem 中。

现在我的 ipsec.conf 文件在系统 r1 中如下所示

conn host-host-rsa

left=1.1.1.1
leftsubnet=192.168.10.0/24
[email protected]
leftauth=pubkey
leftrsasigkey=/root/r1-pub.pem
right=2.2.2.2
rightsubnet=192.168.20.0/24
[email protected]
rightauth=pubkey
rightrsasigkey=/root/r2-pub.pem
type=tunnel
auto=add

在系统 r2 中，配置为

conn host-host-rsa
left=2.2.2.2
leftsubnet=192.168.20.0/24
[email protected]
leftauth=pubkey
leftrsasigkey=/root/r2-pub.pem
right=1.1.1.1
rightsubnet=192.168.10.0/24
[email protected]
rightauth=pubkey
rightrsasigkey=/root/r1-pub.pem
type=tunnel
auto=add

现在，在 r1 上启动 ipsec 时，我收到此错误

我不知道为什么会发生此加载公钥错误。如能提供任何帮助，我将不胜感激。

你需要公钥插件使用原始公钥。如果您指定charon.load确保strongswan.conf将该插件包含在列表中。如果没有，则说明您没有构建该插件，或者您的发行版没有提供该插件。在这两种情况下，您都必须从源代码重建 strongSwan使用适当的./configure选项。
