ping
----

Check if server is running on given host/port. Result reported to standard output.
Usage:
  --ping --host=mach --port=3144  # Check if server alive on host mach & port 3144
  --ping --host=fred              # Check if server alive on host fred and port ECF_PORT,
                                  # otherwise default port of 3141
  --ping                          # Check if server alive by using environment variables
                                  # ECF_HOST and ECF_PORT
If ECF_HOST not defined uses 'localhost', if ECF_PORT not defined assumes 3141

The client considers, for both user and child commands, the following environment variables:

  ECF_HOST <string> [mandatory*]
    The main server hostname; default value is 'localhost'
  ECF_PORT <int> [mandatory*]
    The main server port; default value is '3141'
  ECF_SSL <any> [optional*]
    Enable secure communication between client and server.
  ECF_HOSTFILE <string> [optional]
    File that lists alternate hosts to try, if connection to main host fails
  ECF_HOSTFILE_POLICY <string> [optional]
    The policy ('task' or 'all') to define which commands consider using alternate hosts.

The options marked with (*) must be specified in order for the client to communicate
with the server, either by setting the environment variables or by specifying the
command line options.
