Hello together I'm a little bit confused about manipulation ssl_access_log to get the X-Forward-For IP but not the "WAF/Proxy" IP. (sorry for that long text...) # Settings: rhel 7.3 apache 2.4.6 Redirect: apache redirect (nearly) everthing to https - Apache is behind a Web Application Firewall (WAF). The WAF acts like a reverse proxy I think. - the WAF do only https but let pass through X-Forward-For information - The WAF (or some server via the WAF) do health checks and I don't whant to log them. - The Health checks "source" IP's are WAF IPs (maybe a Cluster): WAF-IP1: 1.2.3.1 WAF-IP2: 1.2.3.2 # apache ssl.conf: <VirtualHost _default_:443> ... LogLevel info ssl:warn #part 1: LogFormat "%l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined LogFormat "%{X-Forwarded-For}i %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" proxy SetEnvIf X-Forwarded-For "^.*\..*\..*\..*" forwarded CustomLog "logs/ssl_access_log" combined env=!forwarded CustomLog "logs/ssl_access_log" proxy env=forwarded #part 2: SetEnvIf Remote_addr ("1\.2\.3\.1"|"1\.2\.2\.2") waf CustomLog "logs/ssl_access_log" proxy env=!waf ... </VirtualHost> # ssl_acces_log: -> part 1. is ok (your see the X-Forward-IP and WAF IP) 78.51.212.20 1.2.3.1 - - [05/Oct/2017:10:58:05 +0200] "GET /asdf/authorize?response_type=code&dddcasdf1&scope=oertz&redirect_uri=https://www.somethere.de/customers/83483227272 HTTP/1.1" 200 1576 "https://www.somethere.de/" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0" -> part 2. is not ok. I can't stop the logging of health checks coming from 1.2.3.1/1.2.3.2. Allthough they are logged twice. 1.2.3.1 - - [05/Oct/2017:10:58:07 +0200] "HEAD / HTTP/1.0" 301 - "-" "-" - 1.2.3.1 - - [05/Oct/2017:10:58:07 +0200] "HEAD / HTTP/1.0" 301 - "-" "-" 1.2.3.2 - - [05/Oct/2017:10:58:08 +0200] "HEAD / HTTP/1.0" 301 - "-" "-" - 1.2.3.2 - - [05/Oct/2017:10:58:08 +0200] "HEAD / HTTP/1.0" 301 - "-" "-" 1.2.3.1 - - [05/Oct/2017:10:58:12 +0200] "HEAD / HTTP/1.0" 301 - "-" "-" - 1.2.3.1 - - [05/Oct/2017:10:58:12 +0200] "HEAD / HTTP/1.0" 301 - "-" "-" 1.2.3.2 - - [05/Oct/2017:10:58:13 +0200] "HEAD / HTTP/1.0" 301 - "-" "-" - 1.2.3.2 - - [05/Oct/2017:10:58:13 +0200] "HEAD / HTTP/1.0" 301 - "-" "-" Hopfully sombody can see the problem / find a solution many thanks marc --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
