I am no expert on apache conf files, but I am reasonably familiar with them. A security plugin I have installed on one of my wordpress sites (https://ithemes.com/security/) makes edits to an .htaccess files in order to enforce automated IP bans (for example, if you have too many failed login attempts in a short period of time). Here is the block that it generated: (xxx added by me for the IP address)
<IfModule mod_authz_core.c>
<RequireAll>
Require all granted
Require not env DenyAccess
Require not ip xxx.xxx.xxx.xxx
</RequireAll>
</IfModule>
<IfModule !mod_authz_core.c>
Order allow,deny
Deny from env=DenyAccess
Deny from xxx.xxx.xxx.xxx
Allow from all
</IfModule>
Now, this causes the site to bomb out with a 500 error. The error I get in my log is
Expected </RequireAll>> but saw </RequireAll>
(Note the extra trailing >). And, lo and behold, if I add an extra >, the site works again.
What syntax rule is at play here? Why on earth do I need the extra > in a closing tag? Why would the (popular and genreally respected) plugin be generating an invalid .htaccess? Since this looks so wrong to me I'm inclined to believe I have some obscure server setting or an outdated apache or something causing this. Any insight would be much appreciated.

I am setting up a WordPress site in a subdomain. The subdomain will be in a subdirectory of the main directory.
So http://dl.abc.com will be in the folder /public_html/dl/
Within there is going to be the wp-admin folder when WordPress is installed:
/public_html/dl/wp-admin/
That wp-admin folder we wanted to block anyone trying to access it (or any files/subdirectories contained within) except those users from Australia and Singapore.
Is this the correct way to go about it? (I suspect a caveat is any plugins that make ajax requests by calling admin-ajax.php won't work properly?)
<ifModule mod_geoip.c>
GeoIPEnable On
# Put countries to allow here
SetEnvIf GEOIP_COUNTRY_CODE NZ AllowCountry
SetEnvIf GEOIP_COUNTRY_CODE SG AllowCountry
Deny from all
Allow from env=AllowCountry
</ifModule>
Second question is how can we go about doing the same thing with the wp-login.php file that will be installed within the /public_html/dl/ folder?
Will this work if we put it in the .htaccess file within the /public_html/dl/ directory? Or is there a better way?
<Files "wp-login.php">
<ifModule mod_geoip.c>
GeoIPEnable On
# Put countries to allow here
SetEnvIf GEOIP_COUNTRY_CODE NZ AllowCountry
SetEnvIf GEOIP_COUNTRY_CODE SG AllowCountry
Deny from all
Allow from env=AllowCountry
</ifModule>
</Files>
?
And lastly, I'd like to have a bit of additional "security through obscurity" in that for both examples above I'd rather return the "404 not found" error instead of the denied error.
What's the best way to do that?
Unfortunately we don't have any sort of dev/test server to try things out with first, so want to get this as close to perfect as possible the first time through.
Thank you.

To answer your second question, according to this page:
https://www.askapache.com/htaccess/using-filesmatch-and-files-in-htaccess/
you can surround other directives with the <Files></Files> or <FilesMatch></FilesMatch> directive:
"The directive limits the scope of the enclosed directives by
filename. It should be matched with a directive. The
directives given within this section will be applied to any object
with a basename (last component of filename) matching the specified
filename. sections are processed in the order they appear in
the configuration file, after the sections and .htaccess
files are read, but before sections. Note that can
be nested inside sections to restrict the portion of the
filesystem they apply to."
So essentially it seems that what you have stated already should work.
I've tried everything. I read other how to threads here and elsewhere. I have the following in my apache2 site configuration file:
<Directory /var/www/html/site_root/>
AllowOverride All
</Directory>
</VirtualHost>
There is no other occurence of "AllowOverride" in the site conf file so it's not a case of something earlier in the file overriding this (don't even know if that's possible). I also tried '/var/www/html/site_root'.
If I try either of the following (or both) in my /var/www/html/site_root/.htaccess file:
<Files .htaccess>
Order Allow,Deny
Deny from all
</Files>
<Files "xmlrpc.php">
Order Allow,Deny
Deny from all
</Files>
I get 520s and the whole site is crashed. I also tried /xmlrpc.php or "xmlrpc.php" without "" and ./xmlrpc.php etc. No matter what I do my error log is full of:
[Thu Dec 03 18:05:25.628237 2015] [core:alert] [pid 6956] [client 192.168.0.1:56529] /var/www/html/site_root/.htaccess: order not allowed here
How can this be and why is this so difficult to do?
My purpose is to block access to /xmlrpc.php. This is an absolute Achilles heel for WordPress. It is very easy to crash and burn any site by just hitting this over and over and over again. For some reason WordPress leaves it wide open by default and Cloudflare is not able to detect or protect against these attacks. They happen all the time and it brings down the server completely.
Thanks.
The best answer I found is this:
If your server is an Apache, you can block access before WordPress is even reached with one line in your .htaccess:
Redirect 403 /xmlrpc.php
You can add another line to keep the response short:
ErrorDocument 403 "die"
That will send a very minimal response (three bytes plus HTTP headers), and it will save your resources for better traffic.

Please go vote up the answer at the wordpress stack, by user #toscho. I don't have enough reputation. Toscho's answer is is way better than the accepted answer because you can deny access in .htaccess and still burn up server resources loading the 404 in Wordpress. His answer actually saves you one byte over mine.
Well did you restart your server after you made changes to apache2.config? Secondly there is a difference between order allow,deny AND order deny,allow
Try using this
<Files xmlrpc.php>
order deny,allow
deny from all
</Files>
You can also disable the XML-RPC Feature, from the system itself. Just put this in your wp-config
add_filter('xmlrpc_enabled', '__return_false');
Update: Some clarification:
I agree with jason, blocking xmlrpc.php at the htaccess level is always a much better idea because even if you disable it through the filter, the site still goes through the whole request cycle. Here filters is just being used as a safeguard from someone getting in, but the site is still open to DDOS attacks. In short usage of filters is only for people who are using it for some other purposes and not finding an escape from DDOS attacks, for eg if someone doesn't have access to the htaccess file.
I have a domain I use for development purposes. In this domain I have several subdirectories with different wordpress installations.
To hide the whole area I made a simple htpasswd protection in the root.
Now I have one of this Wordpress in the domain that uses timthumb library to resize images, and due to the htpasswd, I get "NetworkError: 400 Bad Request" instead of the image.
This is an example of the request that gets the error
http://subdomain.domain.com/WP/wp-content/plugins/plugin-directory/timthumb.php?src=http%3A%2F%2Fsubdomain.domain.com%2FWP%2Fwp-content%2Fuploads%2F2015%2F01%2F012015_valentines_hp_budvase.jpg&w=300&h=620&zc=1
Is there a way to bypass the protection only for that file?
More details on my paths to better read my .htaccess snippets:
I'm in a subdomain pointed to a subdirectory called 'subdomain_folder'
.htaccess I'm working on is located in 'subdomain_folder'
WP is in a subdirectory called 'WP' inside 'subdomain_folder'
Complete Path to WP: '/home/some-folder/public_html/subdomain_folder/WP
Complete Path to Uploads: '/home/some-folder/public_html/subdomain_folder/WP/wp-content/uploads
I tried this:
SetEnvIf Request_URI "^/WP/wp-content/plugins/plugin-dir/timthumb\.php$" allow
AuthType Basic
AuthName "Restricted Area"
AuthUserFile "/home/some-folder/.htpasswds/public_html/subdomain_folder/passwd"
Require valid-user
Order allow,deny
Allow from env=allow
Satisfy any
UPDATE
Someone adviced me that allowing access to timthumb.php file it's pointless, instead I should allow him to make http requests, or allow full access to uploads folders so, I tried the following, allowing requests from localhost ip
AuthType Basic
AuthName "Reserverd Area"
AuthUserFile "/home/some-folder/.htpasswds/public_html/subdomain_folder/passwd"
Require valid-user
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Satisfy Any
Tried both localhost and 127.0.0.1
I even tried to add another .htaccess in the single WP upload folder (where timthumb asks for images) with rule to allow from any
Satisfy Any
Order Allow,Deny
Allow from all
Still I cant' get images shown, and I keep getting the NetworkError: 400 Bad Request" instead of the image.
Last Detail, the .htaccess in the WP directory is a standard wp htaccess --> pastebin.com/8PRqEYQ2
I Found the solution.
The right way is indeed allowing requests from the server itself, but the localhost IP (127.0.0.1) was not the right adress to allow.
I made a Reverse IP Lookup searching for the domain I'm on, and I used that IP.
This is the .htaccess that works
RewriteEngine On
<IfModule mod_authn_file.c>
AuthName "Restricted Area"
AuthUserFile "/home/path-to-passfile/passwd"
AuthType Basic
Require valid-user
Order Deny,Allow
Deny from all
# Use your server ip:
Allow from 111.111.111.11
Satisfy Any
</IfModule>
With this rules I can develop apps using timthumb.php in .htpasswd protected directory.
Criticisms and improvements are welcome :)
We've tried a few things that we found around Google for this, but can't seem to get anything to work.
The Problem
We have a server with around 500 Wordpress websites on it. We're trying to lock down all the wp-login.php pages for every instance to the IP address of our office using a global htaccess - but the individual Wordpress htaccess files are overriding this.
The Environment
We're hosted on an AWS Linux server running Plesk to manage each website / Wordpress instance.
The Question
Is there a way we can set one htaccess file on the server to lock down all of the Wordpress login pages without the individual htaccess files overriding this?
any help or suggestions for a good way to do this, would be appreciated.
Thanks in advance
I assume that you have read up on the RewriteOptions directive. As I explain in Tips for debugging .htaccess rewrite rules and as you have found with WP which generates its own .htaccess files, by default the current path is scanned for .htaccess and the rewrite rules in the lowest are applied unless a higher one specifies a RewriteOptions Inherit in which case it's rules are executed after rules specified in the child scope, and this is the catch-22 in that WP access file generates a [L] flag on all its execution paths preventing the parent rules from firing.
So the answer is to do this with an Apache mechanism other than rewrite and you can use the SetEnvIf directive:
SetEnvIf Remote_Addr "!^192\.168\." forbidden
<Files *>
Order allow,deny
Allow from all
Deny from env=forbidden
</Files>
or
SetEnvIf Remote_Addr "!^192\.168\." forbidden
<Directory /var/www/wproot>
Order allow,deny
Allow from all
Deny from env=forbidden
</Directory>
Clearly you'll need to change the Regexp to your local needs but this should do the biz. The Apache docs give other variants on this, but you should be able to find one which works in your case. Just put this in the a per-virtual server context -- within a Directory(Match) directive if necessary -- or in a common parent directory .htaccess file.
I ended up getting this to work with your first suggestion, but actually without the SetEnvIf line being required, so thanks very much! this was my .htaccess in the /var/www/vhosts folder for anyone else needing this:
<files wp-login.php>
order deny,allow
deny from all
Allow from xxx.xxx.xxx.xxx
</files>
Nice and simple and completely different from the previous routes I was trying to take for this.
I am having problems as some computer from an IP address is trying to access all the files on my server.
How should I change the .htaccess file so that IP address gets NO access at all to any files? And which .htaccess file do I change? It looks like I have one inside each folder.
The basic mod_access module should get you what you need
Order allow,deny
Allow from all
Deny from xxx.xxx.xxx.xxx
Something like that. I dont know the exact syntax. Keep in mind that depending on your exact version of Apache (1.3/2.0/2.2) then the module requirements might be different. I think in 2.2 you need the authz_host module, but in 1.3 its mod_access.
For simple cases, you can try http://wordpress.org/extend/plugins/wp-ban/, which can keep IP or IP range from visiting your blog.
If that's not enough, you can modify .htaccess as follows
Deny from xx.xx.xx.xx/xx
Allow from ALL
Another way, this time using mod_rewrite rules in a .htaccess file.
RewriteEngine on
RewriteCond %{HTTP_HOST} ^123.123.123.123$
RewriteRule ^(.*)$ blocked.html [L,F]
[L,F] means 'stop executing further rules, and return 403 Forbidden as the HTTP status'. blocked.html could contain a message indicating that they've been blocked.
