Re: How to retrieve IP address of incoming packets in text file using httpd source code

[Bhavna Saini <bhavnasaini10@xxxxxxxxx>]

Thanks for the info.

I have gone through customlog and i understand that it is used to log the IP and other parameters,

But I want to compare the IP address of incoming requests with IP address present in a pre-built data structure. After comparing, the request will be served accordingly.
Therefore, I need the source code file of apache which accepts requests and through which I can get the IP at the initial stage.

It would be really helpful if you could provide me this info.

Thanks,

-Bhavna

Eric is saying that normally only root can write to the root file
system directory '/', and therefore a child process, typically running
as apache or www, would not be able to write to it.

Why would you want to edit source code to do that?

CustomLog logs/ip_request.log "%a %U"

http://httpd.apache.org/docs/2.2/mod/mod_log_config.html#customlog

This would create a file at $SERVER_ROOT/logs/ip_request.log with
contents like so:

192.168.1.1 /index.html
192.168.1.10 /favicon.ico
