Attack on my reverse proxy server

Hi, all

We see some attack on our apache reverse proxy server.

180.211.101.213 - - [11/Jun/2012:11:30:00 -400] "POST / HTTP/1.0" 301 324
201.243.47.144 - - [11/Jun/2012:11:30:00 -400] "POST / HTTP/1.0" 400 226
113.162.230.163 - - [11/Jun/2012:11:30:00 -400] "POST / HTTP/1.0" 503 323

How can we block those activities on the apache server? Thanks.

Ryan Jiang

if your server is accessible from the internet, such attacks _will_ come.
you should make sure that such attacks won't affect its functionality.

you can watch logs for that kind of activities and e.g. block source
IPs in firewall (a.g. using fail2ban).

There apparently are apache modules that can to something similar
internally.
