[jboss-jira] [JBoss JIRA] Resolved: (JGRP-1095) MPING: doesn't work with IPv6
[
https://jira.jboss.org/jira/browse/JGRP-1095?page=com.atlassian.jira.plug...
]
Bela Ban resolved JGRP-1095.
----------------------------
Resolution: Done
The reason for the dailure was that the bind_addr in TCP was link-local and scoped
(scope-id=3). This address was then multicast by MPING. The receiver tried to send a
response by connecting to the LL scoped IPv6 address, which failed, so the sender never
got a response.
The solution was to introduce a utility method Util.connect(), which checks if the
destination address is a LL scoped IPv6 address and - if yes - replaces it with an
unscoped one.
MPING: doesn't work with IPv6
-----------------------------
Key: JGRP-1095
URL: https://jira.jboss.org/jira/browse/JGRP-1095
Project: JGroups
Issue Type: Task
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 2.8
Running MPING with TCP works with IPv4, but not with IPv6 (members don't find each
other). The config is
<MPING mcast_addr="ff0e::8:8:5"
mcast_port="7200"
num_ping_requests="1"
timeout="3000"
num_initial_members="3"/>
