Hi everyone, I’ve deployed a server for rsync public mirror,and I use nginx as web server to display some html for visitors. Now the problem is, too many 400 errors. I paste “only a small amount of them” below: # ================================= 216.216.33.242 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 174.128.254.98 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 216.216.33.242 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 207.99.82.229 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 173.255.246.181 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 206.53.187.66 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 173.255.246.181 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 216.40.205.154 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 67.222.104.104 - - [21/Aug/2012:03:02:05 -0700] “GET /centos/5.8/extras/x86\_64/repodata/repomd.xml HTTP/1.1” 200 2146 “-” “urlgrabber/3.1.0 yum/3.2.22” “-” 75.125.106.50 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 75.125.106.50 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 64.28.85.10 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 38.107.176.34 - - [21/Aug/2012:03:02:05 -0700] “GET /centos/5.8/os/i386/repodata/repomd.xml HTTP/1.1” 200 1140 “-” “urlgrabber/3.1.0 yum/3.2.22” “-” 174.36.195.24 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 132.239.242.24 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 64.156.195.66 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 199.180.132.136 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 173.228.120.18 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 209.119.87.126 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 174.137.174.201 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” 208.70.208.200 - - [21/Aug/2012:03:02:05 -0700] “-” 400 0 “-” “-” “-” Well,this really make me confused.And I’ve asked other mirror admins who use nginx,they all have this problem.

It’s just a way how nginx logs connections which are just opened and then closed. Confusing part is that some other web servers doesn’t seem to log anything in this case. Maxim D. ---
