Hi,
We are using Apache 2.2 installed on Linux and I am trying to configure access logs to print real client IP and modified the LogFormat as follows but it doesn't seem to work.Help appreciated.
LogFormat "%{X-Forwarded-For}i %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
Thanks. |

| Are you behind a proxy or why you use X-Forwarded-For ? |

| Yes, we are behind a proxy. Want to trace the actual client IP for trouble shooting purposes. |

Hm a solution might be
| Code: |
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined
LogFormat "%{X-Forwarded-For}i %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" proxy
SetEnvIf X-Forwarded-For "^.*\..*\..*\..*" forwarded
CustomLog "logs/access_log" combined env=!forwarded
CustomLog "logs/access_log" proxy env=forwarded
|
found at http://www.techstacks.com/howto/log-client-ip-and-xforwardedfor-ip-in-apache.html
If the IP is still empty then you have to look into the proxy config since it might not forward the client's IP. |
