Lately I've been seeing a ton of these in the apache access logs:

70.85.51.20 - - [26/Jan/2006:02:26:43 -0600] "GET /blogs/xmlsrv/xmlrpc.php HTTP/1.1" 404 -

70.85.51.20 - - [26/Jan/2006:02:26:43 -0600] "GET /html/xmlrpc.php HTTP/1.1" 404 -


I take it that the "404" means that the target of the hunt was not found, but I am sure that this spiking bandwidth like crazy. I am wondering if there is a way to tweak, or add a new rule to the BFD package, or maybe PortSentry that would stop this after only a few seeks. Anyone?


P.S. What the heck are these about:

210.196.127.184 - - [25/Jan/2006:23:25:02 -0600] "-" 408 -
210.196.127.184 - - [25/Jan/2006:23:25:02 -0600] "-" 408 -
