[jboss-jira] [JBoss JIRA] Reopened: (JBAS-8001) Greater flexibility in picking bind address

Greater flexibility in picking bind address ------------------------------------------- Key: JBAS-8001 URL: https://issues.jboss.org/browse/JBAS-8001 Project: Legacy JBoss Application Server 6 Issue Type: Feature Request Security Level: Public(Everyone can see) Reporter: Brian Stansberry Fix For: No Release Consider adding a capability to the AS along the lines of what Bela did in JGRP-1204. An explanatory comment re JGRP-1204 from Bela: > might be interesting for you if you want to make JGroups bind to a certain *type* of IP address, but don't know the exact address before startup. > > For example, in a cloud environment, you don't usually know the IP address assigned to you instance beforehand, unless you use elastic IPs and dyndns.org entries, for example. > > Since cloud provider often charge you for outgoing traffic on public IPs, you don't want replication or distribution traffic to go out over public IPs ! You rather want this type of traffic to use internal IP address, for > which some provider (e.g. GoGrid) don't charge. > > This can be done by setting bind_addr or -Djgroups.bind_addr to a keyword rather than a dotted decimal or symbolic IP address: > > * GLOBAL: pick a public IP address. You want to avoid this for > replication traffic > * SITE_LOCAL: use a private IP address, e.g. 192.168.x.x. This > avoids charges for bandwith from GoGrid, for example > * LINK_LOCAL: use a 169.x.x.x, 254.0.0.0 address. I've never used > this, but this would be for traffic only within 1 box > * NON_LOOPBACK: use the first address found on an interface (which > is up), which is not a 127.x.x.x address > > For my could mod-cluster demo, I set bind address to SITE_LOCAL. This works for GoGrid, need to see whether this is also true for EC2 and Rackspace This also has implications for the AS 7 domain model.
