公司 VPN 的新证书，现在 openconnect 不起作用

  • 772

因此，感谢工作中的“升级”，我们获得了新的 VPN 证书。它是自签名的，不再有效。这是系统日志：

我看到未找到签名者错误，但它超越了“收到无效的 IP4 配置！” 这是怎么回事，我该如何解决？

或者更好的是，告诉 openconnect 信任自签名证书。

    连接时使用 --servercert 选项有一个解决方法：

    在终端输入

    sudo openconnect --protocol=gp <hostaddress>

    并得到消息：

    Certificate from VPN server "serverhost" failed verification. 
Reason:   signer not found To trust this server in future, perhaps
add this to your command line: --servercert pin-sha256:serverfingerprint 
Enter 'sì' to accept, 'no' to abort; anything else to view:

    然后最后在命令行选项中使用指纹：

    openconnect --servercert=sha1:26cfbcdefg... [usual arguments]

    或者 

    openconnect --servercert=sha256:a8cfbcdedeadbeefdeadbeeffg... [usual arguments]
