How to ping server address? In view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

After purchasing the elastic CVM of the elastic public network IP, it is not possible to ping the elastic public network IP, or the elastic CVM ping is not connected to the public network. How should we solve the problem at this time? we can start from the following aspects.

1. Check security group rules

Check whether the security group corresponding to the ENI of the elastic CVM has allowed the "ICMP" rule of "inbound direction".

two。 Check the "Network ACL" rule

If the host is in East China or South China, you need to check whether the "network ACL" is open. Check whether the ENI bound to "Elastic Public Network IP" is under the subnet associated with "Network ACL". If "Network ACL" is "enabled", you need to add ICMP opening rules to allow traffic.

3. Confirm whether the default route exists in the CVM

Log in to the elastic CVM and execute the ip route command to see if there is a default route. If there is no such route, execute the ip route add default via XXXX dev eth0 command to add the default route.

4. Hosts in the same area perform ping testing

There is no ping-connected elastic public network IP for elastic CVM in the same region to ping. If ping is available, the virtual network is normal. Contact customer service for technical support.

5. Internal troubleshooting of elastic CVM

Confirm whether the elastic CVM is multiple network cards. If it is multiple network cards and the elastic public network IP is bound to a non-primary network card, you need to configure policy routing inside the elastic cloud server.

Log in to the elastic CVM to check whether the Nic has been created and whether the Nic has obtained a private IP address. If you cannot log in to the elastic cloud server with the password set by the user, contact the technical support personnel to obtain the default password to log in.
