> For example, you can't run `ping`, so good luck debugging your networking! Sending ICMP Echo in userspace (over UDP) is a thing on Linux. From experience, for public Internet, where possible, it is always better to rely on TLS connects (then TCP or UDP, and then ICMP) to ascertain connectivity (lest some middleware meddle with IP or Transport replies). |
