The only way to know is actually printing out the exception, either to
stderr, or better using the logging facility, as I suggested.

FYI, your code above is (almost) exactly equivalent to the simpler

    try:
    	host = socket.gethostbyaddr( os.environ['REMOTE_ADDR'] )[0]
    except:
    	host = "Reverse DNS Failed"

ciao, lele.
