docker - 如何解决SG客户的ENOTFOUND错误

Question

我将安全网关的目标主机设置为ssldemo而不是IP地址的主机名。我使用'--net="host"'选项启动了SG Client，以便解析主机名。当然，主机操作系统可以解析主机名。请查看 ping 主机名的日志。但是，执行trx时，SG Client无法解析主机名并出现"ENOTFOUND"错误。我试图添加'--net="host" --add-host "ssldemo:192.168.56.1"'选项，但是出现了同样的错误。

您能教我如何解决"ENOTFOUND"错误吗？

Answer 1

安全网关服务无法识别DNS名称。您可以尝试使用IP地址代替主机名吗？
