[jboss-jira] [JBoss JIRA] (WFLY-6915) Mod cluster not working with non-root user

[Matias Rand (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-6915?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13320718#comment-13320718 ] 

Matias Rand commented on WFLY-6915:
-----------------------------------

Right, digging a bit deeper into the outbound-socket-binding there is an option to set Source Port. When creating an outbound-socket-binding in the web GUI (the pop-up) you don't see an option to set the source port. However, when hitting save and looking at the newly created settings the source port is actually set to 0. I initially thought that meant 0 as in undefined, but it seems indeed to be 0. There is a default outbound-socket-binding called "mail-smtp" that also has source port set to 0. When using jboss-cli to see the outbound-socket-binding settings the "mail-smtp" binding is showing "undefined" for the source port, but my newly created binding is indeed showing 0.
So, setting the source port in the binding to something above 1024 seems to work like a charm, running EAP as a non-root user.
Thank you for pointing me in the right direction.

> When I run wildfly with a non-root user(wildfly)  mod_cluster won't work. I got this error:
> 14:09:06,327 ERROR [org.jboss.modcluster] (UndertowEventHandlerAdapter - 1) MODCLUSTER000043: Failed to send INFO command to relatorios.sistemafieg.org.br/11.12.13.14:6666: Permission denied

> 1. Adding user

> 3. start wildfly and register proxy list and socket binding
