I am not able to get perfect solution from any of the previously posted question so I am asking this again as I am a newbie to elastic. Here what all I have done 1. Installed elasticsearch on linux using git clone. 2. Running elastic using /bin/elasticsearch 3. Runs successfully when there in no change in elasticsearch.yml file 4. When I am changing the network.host: 192.168.0.1 to #network.host: 10.182.XX.XX it is not able to start. ## Linux Installed cat /proc/version Linux version 2.6.32-696.23.1.el6.x86\_64 ([mockbuild@x86-027.build.eng.bos.redhat.com](mailto:mockbuild@x86-027.build.eng.bos.redhat.com)) ## Console snapshot [2018-07-24T19:52:49,248][WARN][o.e.b.ElasticsearchUncaughtExceptionHandler] [] uncaught exception in thread [main] org.elasticsearch.bootstrap.StartupException: BindTransportException[Failed to bind to [9300-9400]]; nested: BindException[Cannot assign requested address]; at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:140) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:127) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:86) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:124) ~[elasticsearch-cli-6.3.1.jar:6.3.1] at org.elasticsearch.cli.Command.main(Command.java:90) ~[elasticsearch-cli-6.3.1.jar:6.3.1] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:93) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:86) ~[elasticsearch-6.3.1.jar:6.3.1] Caused by: org.elasticsearch.transport.BindTransportException: Failed to bind to [9300-9400] at org.elasticsearch.transport.TcpTransport.bindToPort(TcpTransport.java:809) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.transport.TcpTransport.bindServer(TcpTransport.java:774) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.transport.netty4.Netty4Transport.doStart(Netty4Transport.java:135) ~[?:?] at org.elasticsearch.xpack.core.security.transport.netty4.SecurityNetty4Transport.doStart(SecurityNetty4Transport.java:85) ~[?:?] at org.elasticsearch.xpack.security.transport.netty4.SecurityNetty4ServerTransport.doStart(SecurityNetty4ServerTransport.java:41) ~[?:?] at org.elasticsearch.common.component.AbstractLifecycleComponent.start(AbstractLifecycleComponent.java:66) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.transport.TransportService.doStart(TransportService.java:213) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.common.component.AbstractLifecycleComponent.start(AbstractLifecycleComponent.java:66) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.node.Node.start(Node.java:652) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.bootstrap.Bootstrap.start(Bootstrap.java:265) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:335) ~[elasticsearch-6.3.1.jar:6.3.1] at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:136) ~[elasticsearch-6.3.1.jar:6.3.1] ... 6 more Caused by: java.net.BindException: Cannot assign requested address at sun.nio.ch.Net.bind0(Native Method) ~[?:?] at sun.nio.ch.Net.bind(Net.java:433) ~[?:?] at sun.nio.ch.Net.bind(Net.java:425) ~[?:?] at sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:223) ~[?:?] ---

Hi dhananjay, This seems that you are assigning an IP to elasticsearch that doesn't seem to allotted to the machine. Could change the `network.host` value to the IP address of the machine? What is the o/p of `ip addr`? ---

Thanks for replying. I am assigning the host address (ssh ip) in network.host. ---

Are you sure that is the actual IP of the host and not a NAT/PAT IP? What is the output of `ip addr` on the remote machine? ---

I think you are right. Please see the ip addr output 1: lo: \ mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid\_lft forever preferred\_lft forever 2: eth0: \ mtu 1450 qdisc pfifo\_fast state UP qlen 1000 link/ether fa:16:3e:81:4d:e8 brd ff:ff:ff:ff:ff:ff inet 192.168.0.41/24 brd 192.168.0.255 scope global eth0 I should give the IP 192.168.0.41 in network.host right ? ---

Since you are behind a NAT IP, you will have to keep the IP as localhost. What is the use case? Are you planning to use Kibana as well or just elasticsearch? ---

I want to get the server details (like CPU load, Memory size etc) using Elasticsearch and display it on Microsoft Bi dashboard. ---

You could either do a port opening or set up elasticsearch behind a reverse proxy. Please note that there are some security issues with exposing elasticsearch directly without authentication and authorization. See xpack for more details. ---

Port opening - do you mean open the port 9200 in firewall ? Can you please share a link for more information so that I can explore. ---
