Host: Windows 7 – 32 Bit Virtual Box: 4.2.18 r88780 Guest: Solaris 10 2|P age [email protected] 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 age [email protected] You can see the IP address 192.168.56.1 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 age [email protected] 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 (192.168.56.2) with same IP range of default Ethernet adapter Virtual Box Host-Only Network (192.168.56.1) netmask 255.255.255.0, so that putty can connect to Solaris with IP ( 192.168.56.2 ). 5|P age [email protected] 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 2nd Host Only Network at VBox Manager Level From File -> Preferences Menu, You can see the default Ethernet adapter Virtual Box HostOnly Network in Virtual Box Manager as below which came as part of VBox installation. You see the 2nd Host Only Ethernet Adapter at VBox Manager Level (b) Modify the added 2nd adapter’s IP to (192.168.0.102) to be with range of Wi-Fi (192.168.0.101). 6|P age [email protected] (c) Add 2nd 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 age [email protected] 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 (192.168.0.103) for Guest Solaris for newly added network adapter (e1000g1) # dladm show-link e1000g0 type: non-vlan e1000g1 type: non-vlan 8|P age mtu: 1500 mtu: 1500 device: e1000g0 device: e1000g1 [email protected] # dladm show-dev e1000g0 link: up e1000g1 link: unknown ifconfig ifconfig ifconfig ifconfig speed: 1000 speed: 0 Mbps Mbps duplex: full duplex: half e1000g1 plumb up e1000g1 e1000g1 192.168.0.103 netmask 255.255.255.0 broadcast + up 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) 192.168.56.2 netmask 255.255.255.0 New ==== # vi /etc/hostname.e1000g1 192.168.0.103 netmask 255.255.255.0 # cat /etc/hostname.e1000g1 192.168.0.103 netmask 255.255.255.0 -------------------------------------------------------------------------(b) Add the new IP details to /etc/host and name as oranet or (any name) # cat /etc/hosts # # Internet host table # ::1 localhost 127.0.0.1 localhost 192.168.56.2 orasolaris1 loghost 192.168.0.103 oranet loghost -------------------------------------------------------------------------- 9|P age [email protected] (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: # # 128.32.0.0 255.255.255.0 # 192.168.56.0 255.255.255.0 192.168.0.0 255.255.255.0 -------------------------------------------------------------------------(d) Add the Wi-Fi router Default Gateway details to /etc/defaultrouter Follow any one =============== # vi /etc/defaultrouter 192.168.0.1 Default gateway mentioned above for the router OR # route -p add default 192.168.0.1 add net default: gateway 192.168.0.1 add persistent net default: gateway 192.168.0.1 # route -p show persistent: route add default 192.168.0.1 -------------------------------------------------------------------------(e) Add the Wi-Fi router Default Gateway details as nameserver to /etc/resolv.conf vi /etc/resolv.conf nameserver 192.168.0.1 # cat /etc/resolv.conf nameserver 192.168.0.1 -------------------------------------------------------------------------- 10 | P a g e [email protected] (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. # ping www.google.com www.google.com is alive # dig www.google.com ; <<>> DiG 9.6.1-P3 <<>> www.google.com ;; 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: ;www.google.com. ;; ANSWER SECTION: www.google.com. www.google.com. www.google.com. www.google.com. www.google.com. ;; ;; ;; ;; 292 292 292 292 292 IN IN IN IN IN Query time: 90 msec SERVER: 192.168.0.1#53(192.168.0.1) WHEN: Sun Oct 13 00:16:42 2013 MSG SIZE rcvd: 112 # nslookup www.google.com Server: 192.168.0.1 Address: 192.168.0.1#53 Non-authoritative answer: Name: www.google.com Address: 74.125.236.51 Name: www.google.com Address: 74.125.236.52 Name: www.google.com Address: 74.125.236.49 Name: www.google.com Address: 74.125.236.48 Name: www.google.com Address: 74.125.236.50 # ping www.yahoo.com www.yahoo.com is alive 11 | P a g e IN A A A A A A 74.125.236.49 74.125.236.48 74.125.236.50 74.125.236.51 74.125.236.52 [email protected] # nslookup www.yahoo.com Server: 192.168.0.1 Address: 192.168.0.1#53 Non-authoritative answer: www.yahoo.com canonical name = fd-fp3.wg1.b.yahoo.com. fd-fp3.wg1.b.yahoo.com canonical name = ds-fp3.wg1.b.yahoo.com. ds-fp3.wg1.b.yahoo.com canonical name = ds-sg-fp3-lfb.wg1.b.yahoo.com. ds-sg-fp3-lfb.wg1.b.yahoo.com canonical name = ds-sg-fp3.wg1.b.yahoo.com.
