I might have read this wrong, but, it looks like the GW for 10.11.19.54
is 10.11.19.52, because of the second last route. However, 10.11.19.52
doesn't look to be a local network (because there is no "link#..."
route), so the GW is invalid. Hence, when ping calls the sendto()
system call, it returns "Invalid argument", because the GW is
invalid.
