I have now this in my server.xml: For IPv4: <Connector port="80"

With this setup I can connect to port 80 over Ipv4 And IPv6 to my
Linux box.
So, a recap:

* NIO/BIO connector binds to both IPv4 and IPv6 when no "address" is
specified

* APR connector binds only to IPv6 interface is IPv6 is available,
otherwise only IPv4

* Linux vs. Windows is not relevant

Do I have that all right? Or does Linux work as expected (bind to both
interfaces) and Windows does not?

Ideally, this should work everywhere:

<Connector port="80" protocol="HTTP/1.1" />

... and listen on both 0.0.0.0:80 and :::80

The only configuration shown by Zorro has two connectors and says that
works on Windows.

On a Windows Vista PC I have also installed Tomcat 7.0.32 and the
Windows installation set downloaded from tomcat.apache.org uses
per default the Native Library. I have not changed anything in the
configuration yet and on that PC a telnet 127.0.0.1 80 is ok while
a IPv6 telnet ::1 80 fails.
You mean using the above configuration?

So, you have 2 connectors on Windows and one of them doesn't work at
all? Please stop Tomcat, delete all log files, confirm your
(2-connector) configuration, start Tomcat, then re-post your
<Connector> configuration and the complete catalina.out log file, plus
versions of everything all at once.

Better yet, if you could provide a matrix of configurations that *do*
work versus *don't* work, that would be great, too. I'm specifically
interested in knowing if this is a generic APR problem, or only
APR-on-Windows. Jeffrey Janner has had problems on Windows (which may
be a win32 TCP/IP stack problem) but if it doesn't work on Linux,
either, then perhaps it really is a bug with APR or tcnative.

Maybe its worth it to include it in the documentation of the
native library.
Maybe it's worth filing a bug report. If I can get you to cough-up
full details, it will make it much easier.

Chris,

This is what I observed.
Tomcat 7.0.32

1. Linux (Fedora 14, gcc 4.5.1, OpenJDK IcedTea6 1.9.10 java version 1.6.0_20)

One connector for port 80 defined without the address attribute:

* NIO/BIO connector binds to both IPv4 and IPv6 when no "address" is specified * APR connector binds only to IPv6 interface if IPv6 is available, otherwise only IPv4

---------

2. Windows Vista (java version 1.7.0_09)

One connector for port 80 defined without the address attribute:

* NIO/BIO connector binds to both IPv4 and IPv6 when no "address" is specified
 * APR connector binds only to IPv4 interface (not to IPv6).


Regards,
Harm-Jan
