Network Connection Problems on Linux

Network Connection Problems on Linux

On Linux machines you may have problems where JBoss fails to connect to a machine, the symptoms being visible in the log with messages like:

java.net.SocketException: Network is unreachable

This may be a symptom of an IPv6 network stack that takes precedence.

To solve this, add to the JBoss startup options in bin/run.conf or bin/run.bat the following:

-Djava.net.preferIPv4Stack=true

Please refer to http://wiki.jboss.org/wiki/IPv6 for information on a related problem that provides other solutions.
