For example, to forbid to visualize a directory files which hasn't got any index (e.g.: .html, .php), add the code:
Protection by provenance
Authorize only two IP to read the directory:
<Directory /usr/share/phpmyadmin/> <IfModule mod_authz_core.c> <RequireAny> Require all denied Require ip 127.0.0.1 Require ip 127.0.0.2 </RequireAny> </IfModule> </Directory>
whitelist with allow (obsolete in Apache 2.4)
<Directory /usr/share/phpmyadmin/> <IfModule mod_access_compat.c> deny from all allow from 127.0.0.1 allow from 127.0.0.2 </IfModule> </Directory>
If the authorization ranges have some addresses in common with the prohibited ranges, it's better to specify their precedence (the lines order in the .htaccess file doesn't change anything):
order allow, deny
- begin by the authorizations and then start the interdictions, by risking to ban what was previously allowed.
order deny, allow
- the contrary is less restrictive.
<Directory /usr/share/phpmyadmin/> <IfModule mod_authz_core.c> Require all granted Require not ip 127.0.0.1 </IfModule> </Directory>
blacklist avec deny (obsolete in Apache 2.4)
<Directory /usr/share/phpmyadmin/> <IfModule mod_access_compat.c> order allow,deny allow from all deny from 127.0.0.1 </IfModule> </Directory>
Protection by password
It's imperative to allow the authentication parameters modifications in the Apache settings.
The directive AllowOverride of a parent directory must contain the option
The directives to place in the
- authentication type communally adopted but poorly secured.
AuthName "My message"
- the text as an invite in the dialog box.
- the passwords file path.
- specifies that a valid account is needed to accede to the folder.
We can also use
Require user toto sasa to authorize only the two accounts toto & sasa.
The authentication type basic uses not crypted passwords.
Some other more secured types exist, like digest, which is recommended to combine with HTTPS.
The first request is addressed to the protected directory and provokes the displaying of the dialog box, from which the user should identify (with login and password):
- If the password is invalid, the dialog will be displayed again.
- If it's valid, the navigator can record it, and never ask it again until the next relaunching.
The following command creates a passwords file called with one user toto:
htpasswd -c /home/user/www/.htpasswd toto
To add or modify a user:
htpasswd /home/user/www/.htpasswd sasa
Then, tell to .htaccess the .htpasswd path with:
AuthName "Protected page" AuthType Basic AuthUserFile "/home/user/www/.htpasswd" Require valid-user
