For now let's move on. What about routing table and DNS settings? We will need them when configuring our interfaces in manual mode. Note the warning in the resolv. There are some changes in DNS configuration in Solaris 11, we'll talk about them later.
Now, just write down your default router IP address Check again if you can access the Internet again, replace oracle. Most likely, the reason for this error message is that we can't access any DNS servers or they are not configured at all. Routing is not configured. OK, the default gateway was Let's try it:. First ping failure tells us that most likely DNS is not avalable.
Second ping shows that we can at least access our default gateway.

Let's continue moving further and ping our DNS server. We can reach our DNS server, but our system is not configured to use it. That means that in Solaris 11 name service configuration is different from what you used before. Yes, it's a little bit more complicated, but it's more robust and manageable. It's a general direction in Solaris: most of the services are configured via SMF framework, not via config files. Here are the commands:.
Network Configuration for Solaris 11 in VirtualBox
New names. Do you remember the days when you were a junior Solaris system administrator and wondered why all network interfaces in Solaris have these funny names? Now, as you can see, they all are called net0 , net1 , net2 , Much simpler, right? Even more than that: you can give your interfaces your own names. Here is the example.

Imagine we want to use our network interfaces for different services on our Solaris box. We have web server, application server etc. We can name our network interfaces web1 , app0 , db1 etc. Start by deleting the net0 IP interface. One word of advice: having this kind of freedom, please try to avoid long discussions about network interface naming, similar to what you have already had regarding host naming policies. You want to build and manage your application's network infrastructure completely inside the box for development and testing purposes.
First we show the links. Links can be physical or virtual. Note that for physical NICs, we use a new naming scheme net0 , net1 , etc. I assume that the current system has a public network interface with the name net0. I assumeas well that this is the only network interface. IP-forwarding is most likely disabled in this case. It needs to be enabled. The following command enables the IP forwarding through the interfaces net0 and vgb0 :.
The IP-forwarding can be disable after the private virtual network isn't needed anymore. This happens with the following commands:. The zones which will work through the private virtual network will find their way out of the system as well without NAT. The problem arises for IP packets on their back. Systems outside of the PVN will not know about this sub-net and they will not have routes to communicate back. The public interface of the global zone has to act as a proxy and it will have to know how to relay packets back.
This is being done by the ipfilter service which is disabled by default.

The commands below enable the network address translation for the internal network There are chances that you will have to stop the ipfilter service one day. The service can be stopped with this command:. This script will swipe out the configuration which has been configured. It's simple and brutal I expect the virtual switch and the global zone configuration steps already being solved at this point of time. See below:. A bit of planning is required in order to have all data for configure the zone. The following information is needed.
The names which I'm going to use in my commands are already entered:. The zone will have one interface. The zone is now running. The network configuration isn't complete and it takes a login through the zones console with a sys-config dialog. This will lead you into a sysconfig dialog. Choose a manual network configuration and provide the remaining information from the table above and configure the IP address and the default router.
The configuration of name services and NIS is optional. Repeat the same steps for a second zone and you end up with a private virtual network with multiple zones. Accessing the private virtual network is no different to access any lab network through a gate way system.
The global zone can be configured to run an Apache web server as reverse proxy. This allows to direct a browser to web port of the global zone public network interface and work with a specific web server of the internal private virtual network.

The following example assumes that zone1 offers a http service through port 80 at the internal IP address The proxy server gets configured through the httpd. The three directives avoid that the Apache server acts as a regular proxy ProxyRequests Off. The ending slashes matter! The svcadm command starts the Apache server on Solaris as a service. This command assures that the service is up even after a reboot of the system.
This is all it takes on the proxy side! Warning : The web server in the private network may have to know that it's http service is getting exposed by a reverse proxy. Some web applications generate URLs on the fly. This post configuration is however completly application specific.
