Hi,
Fred, I think you may be confusing IPFilter (the Solaris-specific
package) with a generic IP filter.  I might be misunderstanding Mladen
myself, but I think he meant a simple configuration of Tomcat's Remote
Address Valve (http://tomcat.apache.org/tomcat-5.5-doc/config/valve.html)
or a similar component at the javax.servlet.Filter level.

Hi Mladen,

<my apologies for the reply format>

I am curious about your last statement.
I understant that an ip filter is more secure. However, if I am not
mistaken, to setup IPFilter you need to be a sysadmin (aka Root) and you can
lock yourself out if you do not have physical access to the server(s), right
?

So why not a secret word ? It is easy to set and correct. If the file access
permissions are applied properly you can then be certain that the tomcat
will only communicate with the proper Apache(s).  I am sure that the
security gurus would like to see SSL, but that is another thread:)

Thanks - Fred

(Interesting, I just saw that IPFilter is now bundled in Solaris 10, but
many Linux ship with IPTables :(
