2 1) Host, Guest and VBox version. Host: Windows 7 32 Bit Virtual Box: r88780 Guest: Solaris 10 2 P a g e

3 2) Check your current Host and Guest Details Check your Internet / Wi-Fi Wireless Network IP ========================================== From File -> Preferences Menu, You can see the default Ethernet adapter Virtual Box Host-Only Network in Virtual Box Manager as below which came as part of VBox installation. 3 P a g e

4 You can see the IP address which is default from VBox installation on Windows 7. Below DHCP Server details may not be required, you can disable, I kept as it is. 4 P a g e

5 Check the Guest Machine (Solaris) Network Adapter1 to be as below. Connect to Guest VM machine (Solaris) and verify the details as below, Keep IP of Guest Solaris ( ) with same IP range of default Ethernet adapter Virtual Box Host-Only Network ( ) netmask , so that putty can connect to Solaris with IP ( ). 5 P a g e

6 3) Now let s start to configure to enable Internet in Guest Solaris. As I do not want to chance the existing network for Host and Guest. I followed below two steps. (a) Add 2 nd Host Only Network at VBox Manager Level From File -> Preferences Menu, You can see the default Ethernet adapter Virtual Box Host- Only Network in Virtual Box Manager as below which came as part of VBox installation. You see the 2 nd Host Only Ethernet Adapter at VBox Manager Level (b) Modify the added 2 nd adapter s IP to ( ) to be with range of Wi-Fi ( ). 6 P a g e

7 (c) Add 2 nd Network adapter to Guest Solaris VM and Bridge the network with Wi-Fi. Click on your Solaris Guest VM machine then click on network as below 7 P a g e

8 Change the options as per highlighted/shown below. Start the Guest VM Solaris and login with putty to check the added Network Adapter 4) Configure New IP ( ) for Guest Solaris for newly added network adapter (e1000g1) dladm show-link e1000g0 type: non-vlan mtu: 1500 device: e1000g0 e1000g1 type: non-vlan mtu: 1500 device: e1000g1 8 P a g e

9 dladm show-dev e1000g0 link: up speed: 1000 Mbps duplex: full e1000g1 link: unknown speed: 0 Mbps duplex: half ifconfig e1000g1 plumb up ifconfig e1000g1 ifconfig e1000g netmask broadcast + up ifconfig e1000g1 (a) Create a file for new interface (e1000g1) as below, so that IP persist the reboot. ls -ltr /etc/hostname.* -rw-r--r-- 1 root root 38 Oct 12 20:26 /etc/hostname.e1000g0 cat /etc/hostname.e1000g0 (This is existing interface file) netmask New ==== vi /etc/hostname.e1000g netmask cat /etc/hostname.e1000g netmask (b) Add the new IP details to /etc/host and name as oranet or (any name) cat /etc/hosts Internet host table ::1 localhost localhost orasolaris1 loghost oranet loghost P a g e

10 (c) Add the new net mask to /etc/netmasks file vi /etc/netmasks The netmasks file associates Internet Protocol (IP) address masks with IP network numbers. network-number netmask The term network-number refers to a number obtained from the Internet Network Information Center. Both the network-number and the netmasks are specified in "decimal dot" notation, e.g: (d) Add the Wi-Fi router Default Gateway details to /etc/defaultrouter Follow any one =============== vi /etc/defaultrouter Default gateway mentioned above for the router OR route -p add default add net default: gateway add persistent net default: gateway route -p show persistent: route add default (e) Add the Wi-Fi router Default Gateway details as nameserver to /etc/resolv.conf vi /etc/resolv.conf nameserver cat /etc/resolv.conf nameserver P a g e

11 (f) Add dns after file keyword to /etc/nsswitch.conf cat /etc/nsswitch.conf grep hosts: "hosts:" and "services:" in this file are used only if the hosts: files vi /etc/nsswitch.conf. hosts: files dns. cat /etc/nsswitch.conf grep dns hosts: files dns (g) Shutdown the Guest VM Solaris and start again. init 0 (h) Test DNS using dig if website is responding with address. 11 P a g e ping is alive dig ; <<>> DiG P3 <<>> ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 255 ;; flags: qr rd ra; QUERY: 1, ANSWER: 5, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ; IN A ;; ANSWER SECTION: IN A IN A IN A IN A IN A ;; Query time: 90 msec ;; SERVER: ( ) ;; WHEN: Sun Oct 13 00:16: ;; MSG SIZE rcvd: 112 nslookup Server: Address: Non-authoritative answer: Name: Address: Name: Address: Name: Address: Name: Address: Name: Address: ping is alive

13 REF ==== $ ping ping: unknown host The point here is that dig bypasses the host file and goes directly to the dns servers, while ping will obey the Name Service Switch settings as defined in /etc/nsswitch.conf. The solution is simply to edit the file and add the word dns to the line ipnodes: files ipnodes: files dns 13 P a g e
