如何解决 SG 客户端的 ENOTFOUND 错误

Question

我将 Secure Gateway 的目标主机设置为 ssldemo 的主机名，而不是 IP 地址。我使用 '--net="host"' 选项启动 SG Client 以解析主机名。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 无法解析主机名并在执行 trx 时出现 "ENOTFOUND" 错误。我试图添加 '--net="host" --add-host "ssldemo:192.168.56.1"' 选项，但我得到了同样的错误。

你能教我如何解决 "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？

Answer 2

如果您在重新启动以前工作的安全网关连接时遇到 ENOTFOUND 错误，则可能是 Docker 服务本身的问题，因此可以通过重新启动 Docker 来解决您系统上的服务。

如果SG客户端容器还在运行ning，杀掉它：

sudo docker ps
sudo docker kill containerid

重启Docker:

sudo 服务docker重启

重新启动 SG 客户端容器：

sudo docker 运行 -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
