During the recent Double 11, Alibaba Cloud promotional activities are only for new users( 2018 Alibaba Cloud Double 11 New Player New Play ECS as low as 99 yuan per year )We old users can only look at envy. We started to hear from old Tang that we can use Alipay to verify that the new account can be used. When I went to test, this vulnerability was not realized. Although we know that every activity is a business routine, there is no denying that the server solution is relatively affordable, especially for users in need.
Lao Zuo saw a message from a netizen saying that after he bought an AliCloud ECS server, the server could work normally, and the port was OK after setting the security group. But during the ping test, he found that the results were all timeout problems. The problem is that ICMP settings are not added to the security group.
Here we can add the ICMP security group in the inbound direction to the security group.
Just add according to the figure above. After saving, we will see whether PING can be implemented. However, some netizens like to ban PING, so don't keep the default.
