Here's what I found from /var/log/nginx/error.log file.
2012/02/23 04:28:32 [error] 1704#0: *2 open() "/usr/share/nginx/html/MyAdmin/scripts/setup.php" failed (2: No such file or directory), client: 116.255.168.108, server: localhost, request: "GET /MyAdmin/scripts/setup.php HTTP/1.1", host: "199.180.129.222"
is this a hacking attempt?
luckily, I wasn't smart enough to successfully set up the PHP environment...
also, something interesting:
2012/02/23 04:28:31 [error] 1704#0: *1 open() "/usr/share/nginx/html/w00tw00t.at.blackhats.romanian.anti-sec:)" failed (2: No such file or directory), client: 116.255.168.108, server: localhost, request: "GET /w00tw00t.at.blackhats.romanian.anti-sec:) HTTP/1.1", host: "199.180.129.222"
Any suggestions on preventing things like this?
