Paulo Motta commented on CASSANDRA-9748:
----------------------------------------
Updated dtests to check if ports are bound, in addition to logs. I guess in
case log changes we can just update tests. Tested on Windows and works fine.
Let's wait [~RomanB]'s new patch results in his environment before marking this
as ready to commit.
> Can't see other nodes when using multiple network interfaces

> Key: CASSANDRA-9748
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9748
> Project: Cassandra
> Issue Type: Improvement
> Components: Streaming and Messaging
> Environment: Cassandra 2.0.16; multi-DC configuration
> Reporter: Roman Bielik
> Assignee: Paulo Motta
> Priority: Minor
> Labels: docs-impacting
> Fix For: 2.1.x, 2.2.x, 3.0.x
>
> Attachments: system_node1.log, system_node2.log

> The idea is to setup a multi-DC environment across 2 different networks based
> on the following configuration recommendations:
> http://docs.datastax.com/en/cassandra/2.0/cassandra/configuration/configMultiNetworks.html
> Each node has 2 network interfaces. One used as a private network (DC1:
> 10.0.1.x and DC2: 10.0.2.x). The second one a "public" network where all
> nodes can see each other (this one has a higher latency).
> Using the following settings in cassandra.yaml:
> *seeds:* public IP (same as used in broadcast_address)
> *listen_address:* private IP
> *broadcast_address:* public IP
> *rpc_address:* 0.0.0.0
> *endpoint_snitch:* GossipingPropertyFileSnitch
> _(tried different combinations with no luck)_
> No firewall and no SSL/encryption used.
> The problem is that nodes do not see each other (a gossip problem I guess).
> The nodetool ring/status shows only the local node but not the other ones
> (even from the same DC).
> When I set listen_address to public IP, then everything works fine, but that
> is not the required configuration.
> _Note: Not using EC2 cloud!_
> netstat -anp | grep -E "(7199|9160|9042|7000)"
