Bug#560044: net.ipv6.bindv6only=1 breaks java networking
Heikki Henriksen
Version: 6-17-1
Severity: important
Netbase has recently introduced the sysctl-setting
net.ipv6.bindv6only=1 in /etc/sysctl.d/bindv6only.conf and this setting
will probably be the default in squeeze.
This setting breaks networking in java, and any traffic will always
result in a "java.net.SocketException: Network is unreachable".
It should probably be an rc-bug, but setting as important for now, since
users can easily rectify the issue.
Quick fix for users hit by this:
sudo sed -i 's/net.ipv6.bindv6only\ =\ 1/net.ipv6.bindv6only\ =\ 0/' \
/etc/sysctl.d/bindv6only.conf && sudo invoke-rc.d procps restart
cheers,
Heikki
