# Fail2Ban configuration file # # Author: Cyril Jaquier # # [INCLUDES] # Read common prefixes. If any customizations available -- read them from # common.local before = apache-common.conf [Definition] # This filter matches the authorization failures of Apache. It takes the log messages # from the modules in aaa that return HTTP_UNAUTHORIZED, HTTP_METHOD_NOT_ALLOWED or # HTTP_FORBIDDEN and not AUTH_GENERAL_ERROR or HTTP_INTERNAL_SERVER_ERROR. # # As an unauthorized response is the first step for a browser to instigate authentication # so don't set max retry too low. # # Source: # # By searching the code in http://svn.apache.org/viewvc/httpd/httpd/trunk/modules/aaa/* # for ap_log_rerror(APLOG_MARK, APLOG_ERR and examining resulting return code should get # all of these expressions. Lots of submodules like mod_authz_* return back to mod_authz_core # to return the actual failure. # # See also: http://wiki.apache.org/httpd/ListOfErrors # failregex = ^%(_apache_error_client)s (AH01797: )?client denied by server configuration: (uri )?\S*\s*$ ^%(_apache_error_client)s (AH01617: )?user .* authentication failure for "\S*": Password Mismatch$ ^%(_apache_error_client)s (AH01618: )?user .* not found: \S*\s*$ ^%(_apache_error_client)s (AH01614: )?client used wrong authentication scheme: \S*\s*$ ^%(_apache_error_client)s (AH\d+: )?Authorization of user \S+ to access \S* failed, reason: .*$ ^%(_apache_error_client)s (AH0179[24]: )?(Digest: )?user .*: password mismatch: \S*\s*$ ^%(_apache_error_client)s (AH0179[01]: )?(Digest: )?user `.*' in realm `.+' (not found|denied by provider): \S*\s*$ ^%(_apache_error_client)s (AH01631: )?user .* authorization failure for "\S*": \s*$ ^%(_apache_error_client)s (AH0177[56]: )?invalid nonce .* received - (length|hash) is not \S+\s*$ ^%(_apache_error_client)s (AH01788: )?realm mismatch - got `.*' but expected `.+'\s*$ ^%(_apache_error_client)s (AH01789: )?unknown algorithm `\S+' received: \S*\s*"$ ^%(_apache_error_client)s (AH01793: )?invalid qop `.*' received: \S*\s*"$ ^%(_apache_error_client)s (AH01777: )?invalid nonce .* received - user attempted time travel\s*$ ^%(_apache_error_client)s (AH01778: )?user .*: nonce expired \([\d.]+ seconds old - max lifetime [\d.]+\) - sending new nonce\s*$ ^%(_apache_error_client)s (AH01779: )?user .*: one-time-nonce mismatch - sending new nonce\s*$ # Option: ignoreregex # Notes.: regex to ignore.
