You can restrict access to the management console of your product by binding the management console with selected IP addresses. Note that you can either restrict access to the management console only, or you can restrict access to all web applications in your server as explained below. To control access only to the management console, add the IP addresses to the <PRODUCT_HOME>/repository/conf/tomcat/carbon/META-INF/context.xml file as follows:
| Code Block |
|---|
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="<IP-address-01>|<IP-address-02>|<IP-address-03>"/> |
The RemoteAddrValve Tomcat valve defined in this file will only apply to the Carbon management console, and thereby all outside requests to the management console will be blocked. To control access to all web applications deployed in your server, add the IP addresses to the <PRODUCT_HOME>/repository/conf/context.xml file as follows:
| Code Block |
|---|
<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="<IP-address-01>|<IP-address-02>|<IP-address-03>"/> |
The RemoteAddrValve Tomcat valve defined in this file will apply to each web application hosted on the Carbon server. Therefore, all outside requests to any web application will be blocked.
You can also restrict access to particular servlets in a web application by adding a Remote Address Filter to the web.xml file (stored in the <PRODUCT_HOME>/repository/conf/tomcat/ directory), and by mapping that filter to the servlet url. In the Remote Address Filter that you add, you can specify the IP addresses that should be allowed to access the servlet. The following example from a web.xml file illustrates how access to the management page (/carbon/admin/login.jsp) is granted only to one IP address:| Code Block |
|---|
<filter>
<filter-name>Remote Address Filter</filter-name>
<filter-class>org.apache.catalina.filters.RemoteAddrFilter</filter-class>
<init-param>
<param-name>allow</param-name>
<param-value>127.0.01</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Remote Address Filter</filter-name>
<url-pattern>/carbon/admin/login.jsp</url-pattern>
</filter-mapping> |
Note: Any configurations (including valves) defined in the <PRODUCT_HOME>/repository/conf/tomcat/catalina-server.xml file applies to all web applications and is globally available across server, regardless of host or cluster. See the official Tomcat documentation for more information about using remote host filters. |
