ssl - syslog-ng 无法通过 tls 发送日志 - 握手错误

标签 ssl syslog syslog-ng

无法使用 TLS 将日志发送到 syslog-ng docker 容器 (6514) 日志正在成功传输，未在端口 601 上使用 TLS。

在端口 601 非 tls 上使用 loggen 生成系统日志消息

syslog 消息日志(601 conn)

当我使用 TLS 时，我收到以下错误

最佳答案

您已经使用 loggen --use-ssl 和 openssl s_client 测试了您的配置，但未指定客户端证书(loggen 不支持客户端证书，openssl s_client 可以)。

服务器端的错误消息是关于缺少客户端证书:peer did not return a certificate。

如果您不想使用相互身份验证，您可以通过在服务器配置中添加 peer-verify(optional-trusted) TLS 选项使其成为可选项:

source test2_s {
    network(
        port(6514)
        transport("tls")
        tls( key-file("/etc/syslog-ng/cert.d/serverkey.pem")
             cert-file("/etc/syslog-ng/cert.d/servercert.pem")
             ca-dir("/etc/syslog-ng/ca.d")
             peer-verify(optional-trusted)
        )
    );
};
