[jira] [Created] (ARTEMIS-2792) Wrong default network pinger command for linux

Domenico Bruscino created ARTEMIS-2792:
------------------------------------------

             Summary: Wrong default network pinger command for linux
                 Key: ARTEMIS-2792
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-2792
             Project: ActiveMQ Artemis
          Issue Type: Bug
            Reporter: Domenico Bruscino


The network pinger uses a network timeout as an argument for -t in the ping command.

The linux man page for ping says -t sets TTL, which is "The TTL value of an IP packet represents the maximum number of IP routers that the packet can go through before being thrown away. In current practice you can expect each router in the Internet to decrement the TTL field by exactly one."

It looks like the intent was to use -w timeout, in seconds, before ping exits regardless of how many packets have been sent or received.
