ubuntu - I bought a VPS and can connect via SSH, but cannot ping?

Question

The system is ubuntu. I turned off the firewall but can't ping;
The server can ping Baidu;;;; Thank you all, there is another question: I opened an interface with node, and the IP access has always been ERR_CONNECTION_TIMED_OUT?

Answer 1

In addition to system-level problems, the computer room may also prevent external pings from the hardware firewall, which is normal

Answer 2

Whether the system allows Ping is determined by two factors: A. Kernel parameters, B. Firewall. Ping needs to be allowed at the same time if both factors are allowed. Ping cannot be allowed if either of the two factors is disabled.

Answer 3

Some merchants prohibit ping by default.
