           Summary: Tomcat uses hardcoded 127.0.0.1 for localhost
           Product: Tomcat 6
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


Tomcat uses IP 127.0.0.1 when talking to localhost. This will be correct in most
cases but will not work on special setups, e.g. linux vserver guests where
127.0.0.1 is the host machine, the guest machine "localhost IP" can be any other
(e.g. 127.0.0.2 or 10.0.0.1). Though unusual, such configuration seems to be ok
according to the IP RFCs. 

The problem is that tomcat ignores this possibility and does not ask the OS for
the localhost IP via getAddressByName("localhost"), it uses a hardcoded
127.0.0.1, e.g.

./java/org/apache/catalina/startup/Catalina.java:            Socket socket = new
Socket("127.0.0.1", server.getPort());
