Going through my assess-logs today, I found so many entries trying to access pages. (that were not present). Like

  • robots.txt (I know what this is used for)
  • apply
  • favicon.ico(I know what this is used for)
  • etc

So, obviously a 404 was returned but there was other 3 digit code(?) along with 404.

ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 312
ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 285
ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 286
ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 287
ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 288
ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 289
ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 290
ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 295
ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 296
ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 297
ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 298
ip-address - - [date & time] "GET /some/file_OR_folder HTTP/1.1" 404 301

A search gave me this: Samples of attacks detected by ossec - OSSEC Wiki: Which says it was a web scan detected by ossec (looking for Wordpress, xmlrpc and awstats) .

What the second status codes(286, 289) for in the above log?

They aren't status codes, they're the response length in bytes.

Thanks. If every request(from same ip) I saw was a 404 , then the same error page should be delivered back why is the change in the length? – ThinkingMonkey Jan 25 at 20:06

@ChrisS hmmm... gotta go through http headers a bit. Thanks. – ThinkingMonkey Jan 25 at 20:09

@ChrisS that is the length of the reply without the header. The length of the requested filename makes the difference. – ott-- Jan 25 at 20:14
