Prevent access to certain webapps in Tomcat6

问题

I asked this on server fault but really havent had much luck, hoping that someone here would be able to offer some advice...

I have a Tomcat 6 server running just fine. I have external access working. I wanted to know how to prevent someone from seeing specific webapps, for example, I dont want external access to the ROOT tomcat page. How would I go about preventing some webapps while leaving other webapps visible to external users ?

Here's what I've tried: This denies everything even 127.0.0.1 requests

<Host name="localhost"  appBase="webapps"
                unpackWARs="true" autoDeploy="true"
                xmlValidation="false" xmlNamespaceAware="false">

    <Context path="/examples" docBase="" >
       <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127.0.0.1"/>
    </Context>
  </Host>

This denies everything as well.

<Host name="localhost"  appBase="webapps"
                    unpackWARs="true" autoDeploy="true"
                    xmlValidation="false" xmlNamespaceAware="false">

        <Context path="/examples" docBase="" >
           <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="*"/>
        </Context>
      </Host>

Basically I am trying to prevent access to the ROOT default tomcat page and the example apps....

Any ideas?

回答1:

You can't use a wild card for the allow attribute...on the other hand you can use one for the deny attribute.

<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="*"/>

This is why I was getting a 403 with the above code.

Also another way I handled this was I created a jsp that redirected traffic to wherever I wanted.

回答2:

take a look at the documentation. http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html

What you have seems to be correct. it says "If this attribute is specified, the remote address MUST match for this request to be accepted."

One thing you might look at is to see whether 127.0.0.1 is really the correct IP. You might be actually using the actual IP of the box. try adding that IP address after the localhost one.

回答3:

The value of the "allow" property must be defined using backslashes to escape the dots of the allowed IP address:

<Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127\.0\.0\.1"/>

回答4:

This could be an IPv6 issue. This is what my tomcat6/Catalina/myApp.xml looks like:

<!--<?xml version="1.0" encoding="UTF-8"?> -->
<Context path="/myApp" privileged="true">
     <Valve className="org.apache.catalina.valves.RemoteAddrValve" allow="127\.0\.0\.1,0:0:0:0:0:0:0:1"/>
</Context>

This can be tested by the following which would yield 403 if you're denied access

wget --inet4-only http://localhost:8080/myApp
