IP address Assignment problem

[Ayoub Raffoul <ar...@hotmail.com>]

Hello,

I'm running Apache Tomcat ver. 4.1 on a Windows 2000 server. The machine has 
multipe IP addresses. I have configured Apache Tomcat in server.xml to run 
on a specific IP address port 80 as follows (fake IP address):

    <Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
port="80"               minProcessors="5" maxProcessors="75"
               enableLookups="true" redirectPort="8443"
               acceptCount="100" debug="0" connectionTimeout="20000"
               useURIValidationHack="false" disableUploadTimeout="true" 
address="205.200.21.30"/>

I also need to run IIS on the same machine though on a different IP IE: 
205.200.21.31 and port 80. Each time I try to launch IIS I get an error 
message saying port is in use. If I shut down Tomcat then the port get 
released and I'm able to launch Tomcat. It seems that Tomcat is reserving 
all ports # 80 for all IP addresses on this machine. This configuration was 
working correctly in an older version of Tomcat.
Even though Tomcat seems to be reserving all port 80 for all IP addresses it 
is only responding to 205.200.21.30.

Vice Versa is also a problem. If I shut down Tomcat and start IIS on 
205.200.21.31:80, Tomcat will no longer launch on 205.200.21.30:80. It will 
report that the port is in use.

Has anybody encountered a similar issue? Your help is highly appreciated.

Thank you

A port denotes an application, so i'm suprised you were previously able 
to have 2 applications on the same machine on the same port. In other 
words, the OS needs be aware and support different-IP-same-port 
distinction. I don't know if Win or others do that.
