/**
* Determines if services are running on the IBM i system.
*
*
* JPing can be run as a command line program, as follows:
*
* java com.ibm.as400.util.JPing systemName [ options ]
*
* Options:
*
*
*
* -help
* - Displays the help text.
* The -help option may be abbreviated to -h.
*
*
-service serviceName
* - Specifies the specific service to ping.
* The -service option may be abbreviated to -s. The valid
* services include: as-file, as-netprt, as-rmtcmd, as-dtaq,
* as-database, as-ddm, as-central, and as-signon. If this
* option is not specified, by default, all of the services
* will be pinged.
*
*
-ssl
* - Specifies whether or not to ping the SSL port(s).
* The default setting will not ping the SSL port(s).
*
*
-timeout
* - Specifies the timeout period in milliseconds.
* The -timeout option may be abbreviated to -t. The default
* setting is 20000 (20 sec).
*
*
-verbose
* - Specifies verbose output.
* The -verbose option may be abbreviated to -v. The default
* setting is non-verbose.
*
*
*
* Here is an example of calling JPing from the command line:
*
*
* java com.ibm.as400.util.JPing myServer -service as-signon -ssl -timeout 10000
*
* The JPing output will look something like the following:
*
* Verifying connections to system myServer...
*
* Successfully connected to server application: as-signon-s
* Connection Verified
*
*
* To determine from within a program, if the services are running, use
* {@link com.ibm.as400.access.AS400JPing AS400JPing}.
*
