Yes, I understood that. > Any other way of doing this or reason i can find out whats causing this?

Or tell us where to get the code that you are using. > thanks for your help --- ~Randy - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
