Comments on: Apache IPv6 Configuration: Dual Stacked IPv4 & IPv6 Virtual Hosts

The correct way to do this is

……

That’s a space after the ipv4 address and then encase in square brackets your IPv6 address

ensure your namevirtualhost setting is defined for both
NameVirtualHost 74.86.48.99
NameVirtualHost [dead:beef:::1]

and to Scott, you could just use Listen *:80, but I cant see why it would complain for two separate statements

Making two ‘Listen’ statements gives an error that port 80 is already in use. Any ideas, anyone?

$ sudo /etc/init.d/apache2 start
* Starting web server apache2
(98)Address already in use: make_sock: could not bind to address [2600:3c01::f03c:91ff:fe96:edba]:80

Vivek;

I just read through your article on Dual Stack setup for Apache looking for a clue to solve a problem I have here. I’m trying to set up a Tomcat over Java to run in a IPv6 only test network with no luck. I can’t get the ports 8080, 8081 and 8082 to bind to IPv6. I’ve dug around in both Tomcat and Java and found what I thought were some promising fixes like Java’s java.net.preferIPv4Stack=false and java.net.preferIPv6Addresses=true. I can’t quite figure out what I need to do to get the 8080 ports to bin to IPv6. I’d be happy if I could get the ports to bind with both IPv6 and IPv4.

The Tomcat configuration works fine under IPv4. When I attempt to connect to the website using IPv6 the connection request is reset by the server, I’m guessing because the port isn’t available on IPv6.

Any thoughts? I’m searching for clues…..

Thanks…
