Try using 'commands' instead


	import commands

	status, output = commands.getstatusoutput ("ping...")


status will hold the exit status of the ping command.

I use it with '-c 1' to just ping once and return and status will hold a
0 if suceess.  output holds a string of pings output that I guess you
could parse.
