Hi,

I have configured ES (server) and client with ("network.host") to be able  
to work on a machine without internet access (no ip address) but that fails

Client

```
    // Configure Node Instance (= Client)
    NodeBuilder builder = nodeBuilder()
            .local(false)
            .data(false)
            .client(true)
            .clusterName("KARAF");

    Settings settings = settingsBuilder()
            .put("network.host", "127.0.0.1")
            .build();

    builder.settings(settings);

    // Get the Node and start it
    Node node = builder.node();

    Client client = node.client();

```

Server

```
    String settingsSource = getClass().getName().replace('.', '/') + 

```

".yml";  
Settings finalSettings = settingsBuilder()  
.loadFromClasspath(settingsSource)  
//.put(defaultSettings)  
//.put(settings)  
//.put("cluster.name", "test-cluster-" +  
NetworkUtils.getLocalAddress().getHostName())  
.put("cluster.name","KARAF")  
.put("http.enabled", "true")  
.put("node.data", true)  
.put("path.data", DEFAULT\_DATA\_DIRECTORY)  
.put("path.plugins",pluginDir.getAbsolutePath())  
.put("name", id)  
.put("discovery.type", "zen")  
.put("discovery.zen.multicast.enabled", false)  
.put("discovery.zen.ping.unicast.enabled", true)  
.put("discovery.zen.unicast.hosts", "127.0.0.1")  
.put("network.host","127.0.0.1")  
.build();

```
    if (finalSettings.get("gateway.type") == null) {
        // default to non gateway
        finalSettings = 

```

settingsBuilder().put(finalSettings).put("gateway.type", "none").build();  
}

```
    if (finalSettings.get("cluster.routing.schedule") != null) {
        // decrease the routing schedule so new nodes will be added 

```

quickly  
finalSettings =  
settingsBuilder().put(finalSettings).put("cluster.routing.schedule",  
"50ms").build();  
}

```
    Node node = nodeBuilder()
            .settings(finalSettings)
            .local(false)
            .build();

```

What should be the config in that case ?

Charles

Does it have a network adapter at all? You might need to install a loop  
back adapter so that you've got a network adapter to bind to 127.0.0.1  
(I've not done this with ES, but I have had to do this with other software  
on a machine with no network card).

If there is a lo0 interface, why does that not work ? Do we have to modify  
NettyTransport code of ES ?
