General description: When PAR is run with the Turns Engine option (-m) it will fail if the command "ping" is not found in the user's path statement. The ping command is needed to verify that the nodes specified by the user for running remote jobs, are available on the network.
解决方案
PAR will be enhanced in version A2.1 so that if ping is not found in the user's path, it will assume /usr/sbin/ping for Solaris machines.
