> 9000 CQL port?? Do you mean 9042? There are two address/ports - one is listen (internode communication) and second is CQL (rpc in YAML terms). Look at YAML explanation on listen_address and rpc_address
Actual configuration depends on how many network card each node have, is it NAT or not, etc. Can you give more detail about your network environment?

It means if I want to run Cassandra on multi instance environment I only have to change the listen address of each instance and the 9000 CQL port?? --- Mehdi Bada | Consultant Phone: +41 32 422 96 00 | Mobile: +41 79 928 75 48 | Fax: +41 32 422 96 15 dbi services, Rue de la Jeunesse 2, CH-2800 Delémont mehdi.b...@dbi-services.com www.dbi-services.com ⇒ dbi services is recruiting Oracle & SQL Server experts ! – Join the team ----- Original Message ----- From: Vladimir Yudovin <vla...@winguzone.com> To: user@cassandra.apache.org Sent: Tue, 04 Oct 2016 18:18:19 +0200 (CEST) Subject: Re: Cassandra listen port Actually the main port is 9042 - for client (CQL) connections and 7000 (7001 if SSL enabled) for inter node communications.
