JGroups diagnostics opens listening sockets on all interfaces on a multi-homed host ----------------------------------------------------------------------------------- Key: JGRP-1403 URL: https://issues.jboss.org/browse/JGRP-1403 Project: JGroups Issue Type: Bug Affects Versions: 2.8 Environment: Linux Reporter: Witold Wojciechowski Assignee: Bela Ban Netstat Linux utility reports that my application using JGroups opens sockets on all multicast-capable interfaces and subscribes to a multicast address specified for use by diagnostics (per documentation), despite explicit specification of the bind_addr property as Java system property. That is undocumented, and unexpected. (The setting of bind_addr has the expected effect for the regular, JGroups data sockets.) We tried to disable diagnostics altogether, by using the enable_diagnostics=false, but it makes no difference. We tried to set receive_on_all_interfaces=false, but it makes no difference, We also tried to set the the receive_interfaces=<our desired interface IP address> besides setting bind_addr, and it also makes no difference. Our application does not use the xml configuration file for the JGroups protocol stack, and we do it programmatically via setting appropriate Java system properties instead, before any JGroups functionality is invoked. This is done so, because the multicast addresses our application uses are not static (are determined at run time). I am not attaching any sample code, since any sample program when run on a multi-homed machine will reproduce the problem. Any comments on this behaviour would be greatly appreciated. -- This message is automatically generated by JIRA.
