getting Cassandra to listen to eth0 for port 9042
Hello,
I installed version 2.1.3 on my AWS EC2. I installed by downloading the tar and copying it to /opt/ dir and then just ran the bin/cassandra executable. I am trying to access this instance from a Java client. But the problem I am having is that I can only get port 9042 to listen to the loopback interface (127.0.0.1). Regardless of what value I use for "listen_address:" or "listen_interface:". It seems like those properties do not affect port 9042, only port 7000 I think. Is there anyway I can get Cassandra to listen on the interface I want for port 9042? thanks jose

Ali,
Your script (https://gist.github.com/aliakhtar/3649e412787034156cbb) worked. Also, I notice what my problem was... didn't read the two lines above the "listen_address" property in the yaml file...
# Please note that the address on which the native transport is bound is the# same as the rpc_address. The port however is different and specified below.
When I set rpc_address to 0.0.0/0 it worked. Thank you for your help!!

Yeah I used the private IP, which is the IP configured on eth0.
...listen_address: 10.x.x.x
...ifconfig | grep inet inet addr:10.x.x.x Bcast:10.146.160.255 Mask:255.255.255.0
....tcp 0 0 10.x.x.x:7000 0.0.0.0:* LISTENtcp6 0 0 127.0.0.1:9042 :::* LISTEN

On AWS, I've had to use the 'private IP' of the ec2 instance as the listen_address in order to get things to work.
In your EC2 dashboard, there will be a private ip as well as public ip for the instance. Try using the private ip for the listen_address.
Also, you might have more luck installing via one of the packages than via the tar.gz .
