Question

我们有1TB容量的EC2 Redhat实例。将卷修改为2TB后，当我们尝试通过SSH访问服务器时，它会抛出错误Network Error : Request time out。

我们按照Requesting Modifications to Your EBS Volumes - Amazon Elastic Compute Cloud修改了音量。

有人可以帮助我解决此问题吗？

调试日志：

OpenSSH_for_Windows_7.6p1, LibreSSL 2.6.4
debug3: Failed to open file:C:\\Users\\Max-Asset-03/.ssh/config error:2
debug3: Failed to open file:C:\\ProgramData\\ssh/ssh_config error:2
debug2: resolving "<ip>" port 22

debug3: finish_connect - ERROR: async io completed with error: 10060, io:000001B6073FB750
debug1: connect to address <ip> port 22: Connection timed out
ssh: connect to host <ip> port 22: Connection timed out

Answer 1

这是我要采取的方法：

 1. Try doing a Telnet to port 22 from your env and see if it connects
 2. If it does not connect then you should look at your security group first and see if you have open inbound rule to port 22
 3. If you think you have the sec group open then i would look at NACL layer.
 4. If you think that is also not the issue, you should see are you in the public subnet

这应该使您对什么地方出了错

Answer 2

基本上，与网络相关的问题会出现“网络错误：请求超时”错误。

您可以进行故障排除的可能性如下：

确保您的NACL规则没有障碍。
您的IP地址可能会被列入黑名单。

[访问spamhaus.org，检查您的IP地址是否已列入黑名单”。如果是，则将IP列入白名单，然后尝试再次登录。

此外，当EC2实例处于“运行”状态时，可能由于E2实例上的活动而损坏了EBS卷。如果是，请尝试使用快照恢复EBS卷（以防万一）。

希望这会有所帮助。
