如何解决 SG 客户端的 ENOTFOUND 错误

Question

我将安全网关的目标主机设置为主机名ssldemo，而不是IP地址。我用'--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，SG Client无法解析主机名，在执行trx时出现"ENOTFOUND"错误。我试图添加'--net="host" --add-host "ssldemo:192.168.56.1"'选项，但我得到了相同的错误。

你能教我如何解决"ENOTFOUND"错误吗？

Answer 1

如果在重新启动以前工作的安全网关连接时出现ENOTFOUND错误，这可能是Docker服务本身的问题，因此可以通过在系统上重新启动Docker服务来解决。

如果SG客户端容器仍在运行，则终止它：

• sudo docker ps
• sudo docker kill 集装箱

重新启动Docker:

• sudo服务docker重启

重新启动SG客户端容器：

• sudodocker run-it ibmcom/secure gateway client clientid

不要更新您的访问控制列表：

• acl允许 主机：端口

安全网关服务无法识别DNS名称。你能试着用IP地址代替主机名吗？
