Hi Guys, Can some tell what number represents what protocol in "listening_ports" table. For example here protocols value is 6. what does it mean? TCP/UDP or any other protocol if any. Here state "ESTABLISHED" suggest TCP connection. But I would to know if protocol number can be mapped to protocol name. Can anyone please either give reference to a document or list its type.

{
  "family": 2,
  "fd": 3,
  "local_address": "45.55.41.97",
  "local_port": 22,
  "net_namespace": 4026531957,
  "path": "",
  "pid": 29831,
  "protocol": 6,
  "remote_address": "128.199.169.146",
  "remote_port": 42266,
  "socket": 32357509,
  "state": "ESTABLISHED"
}

Thanks for your help.

Thanks a lot. 🙂
