I want to disable reverse DNS in Apache 2. I have done the following steps:
HostnameLookups is set as
Tcpdump session confirmed thatApache was doing double reverse lookups even though the HostnameLookupsdirective was clearly turned off.
No hostnames insites-available. The problem still remains.
UPD: version of apache is
dpkg -l | grep apache2 ii apache2-mpm-prefork 2.2.16-6+squeeze4 Apache HTTP Server - traditional non-threaded model ii apache2-utils 2.2.16-6+squeeze4 utility programs for webservers ii apache2.2-bin 2.2.16-6+squeeze4 Apache HTTP Server common binary files ii apache2.2-common 2.2.16-6+squeeze4 Apache HTTP Server common files apache2 -l Compiled in modules: core.c mod_log_config.c mod_logio.c prefork.c http_core.c mod_so.c
I think mod_security is not present.
