CustomLog for Apache

**MasterTH** · Jan 13th 2014

Hi there,

is it possible to define a customlog-format for the apache logger?? I know imscp uses an own logger-script and in the code or config i can't find a place to define it, so i hope you can help me.

i'de like to change the default log-format of one of our servers to display the X-Forwarded-For entry instead of the host-ip. We've got a WAF infront of that server.

Is there a possibility without opening a completly new log-file?

Kind regards
MasterTH

Hello ;

Look at the LogFormat directive into the /etc/apache2/sites-available/00_nameserver.conf file (Not recommended).

Look also at the libapache2-mod-rpaf module, which is a better alternative for that purpose (Recommended).

BTW: If you change the log format, awstats will be broken. You are warned.

Code

root@wheezy:/var/log/apache2/domain.tld# LANG=C aptitude show libapache2-mod-rpaf
Package: libapache2-mod-rpaf
State: not installed
Version: 0.6-7
Priority: extra
Section: httpd
Maintainer: Sergey B Kirpichev <skirpichev@gmail.com>
Architecture: amd64
Uncompressed Size: 67.6 k
Depends: apache2 | apache2-mpm, libc6 (>= 2.2.5)
Description: module for Apache2 which takes the last IP from the 'X-Forwarded-For' header
rpaf is short for reverse proxy add forward.
rpaf is for backend Apache servers what mod_proxy_add_forward is for frontend Apache servers. It does exactly the opposite of mod_proxy_add_forward written by Ask Bjorn Hansen.
It changes the remote address of the client visible to other Apache modules when two conditions are satisfied. First condition is that the remote client is actually a proxy that is defined in httpd.conf.
Secondly if there is an incoming X-Forwarded-For header and the proxy is in its list of known proxies it takes the last IP from the incoming X-Forwarded-For header and changes the remote address of the client
in the request structure.
