Hi I have Ubuntu 14.04 (upgraded from 12.04) with this: Server version: Apache/2.4.7 (Ubuntu) Server built: Apr 3 2014 12:20:25 Server's Module Magic Number: 20120211:27 Server loaded: APR 1.5.1-dev, APR-UTIL 1.5.3 Compiled using: APR 1.5.1-dev, APR-UTIL 1.5.3 Architecture: 32-bit Server MPM: prefork threaded: no forked: yes (variable process count) Server compiled with.... -D APR_HAS_SENDFILE -D APR_HAS_MMAP -D APR_HAVE_IPV6 (IPv4-mapped addresses enabled) -D APR_USE_SYSVSEM_SERIALIZE -D APR_USE_PTHREAD_SERIALIZE -D SINGLE_LISTEN_UNSERIALIZED_ACCEPT -D APR_HAS_OTHER_CHILD -D AP_HAVE_RELIABLE_PIPED_LOGS -D DYNAMIC_MODULE_LIMIT=256 -D HTTPD_ROOT="/etc/apache2" -D SUEXEC_BIN="/usr/lib/apache2/suexec" -D DEFAULT_PIDLOG="/var/run/apache2.pid" -D DEFAULT_SCOREBOARD="logs/apache_runtime_status" -D DEFAULT_ERRORLOG="logs/error_log" -D AP_TYPES_CONFIG_FILE="mime.types" -D SERVER_CONFIG_FILE="apache2.conf" Loaded Modules: core_module (static) so_module (static) watchdog_module (static) http_module (static) log_config_module (static) logio_module (static) version_module (static) unixd_module (static) access_compat_module (shared) alias_module (shared) apreq_module (shared) auth_basic_module (shared) authn_core_module (shared) authn_file_module (shared) authz_core_module (shared) authz_groupfile_module (shared) authz_host_module (shared) authz_user_module (shared) autoindex_module (shared) cgi_module (shared) deflate_module (shared) dir_module (shared) env_module (shared) filter_module (shared) headers_module (shared) mime_module (shared) mpm_prefork_module (shared) negotiation_module (shared) perl_module (shared) php5_module (shared) reqtimeout_module (shared) rewrite_module (shared) rpaf_module (shared) setenvif_module (shared) status_module (shared) This is from apache2.conf: RPAFproxy_ips 127.0.0.1 RPAFEnable On RPAFsethostname On RPAFheader X-Real-IP No error on startup, so mod_rpaf module surely loaded. Also, i have nginx as frontend which proxies requests to apache (backend) with php5. The problem is that apache recieves X-Real-IP with correct client IP and php can see it ($_SERVER["HTTP_X_REAL_IP"]) but mod_rpaf does not change $_SERVER['REMOTE_ADDR'] variable. Problem occured after upgrading my system from 12.04 to 14.04 directly using "do-release-upgrade -d" command. Does someone know, how to fix this? --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
