I have some problems that seem to be related to the interoperation of ipv4
client programs and ipv6 servers or the other way round.
I'm running FreeBSD 6.1 RELEASE.
I have the following problems:
MySQL and JDBC client
--------------------------
I run MySQL 5.1 server at the FreeBSD machine.
The msyql jconnecter version is 5.0.4.
Via netstat I can see MySQL run as a tcp4 server only.
When connecting to mysql from the server running mysql via the mysql client
program everything works as expected.
When connecting from a remote machine running ipv4 via both the mysql clent
program and via JDBC again everything works as expected.
When connecting from the server running mysql via JDBC I get the exception:
com.mysql.jdbc.CommunicationsException: Communications link failure due
to underlying exception:
java.net.SocketException: java.netConnectionException: Connection
refused
Jetty (org.mortbay.org)
-----------------------
When running jetty as a servelet engine/web server at the FreeBSD machine. I
cannot connect to the server from a remote machine running IPv4. Via netstat
I can see that jetty runs as a tcp6 server only.
SVN (subversion.tigirs.org)
---------------------------
Originally I had a simular problem connecting to svn from a ipv4 machine,
when svn was running as a tcp6 server.
Via a strange startup option (--listen-host=0.0.0.0) I could force svn to
run as tcp4. And connection from the remote host worked fine.
Tomcat
--------
I installed tomcat 5.5.20 from the BSD port. Tomcat does not start. The log
files shows the following:

Has anyone got any ideas what is wrong and how to solve these problems?
Is there a way to force the server to only run ipv4 or to force some
programs to run ipv4?
Please help!
