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 task 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.
