Occasionally, my students loose their network connection when copying their virtual machines. This article shows you how to rebuild your Internet connection.
The first step requires you to identify the port number on your host operating system, which is typically Windows OS or Mac OS X. You can find that by running the following search from a Mac OS X Terminal session or Windows OS Command session.
If you’re on the Mac OS X, you launch a Terminal session and then use the
sudo command to open a shell as the
root super user, like this:
root super user on Mac OS X , you run the
netstat command like this:
sh-3.2# netstat -a | grep 1.ntp | grep -v grep udp4 0 0 192.168.147.1.ntp *.*
VMware uses the same subdomain with one difference for the gateway, it uses node 2:
The alternate syntax to find Vmware’s subdomain requires you to use an Administrator account on Windows, like this:
C:\> netstat -a | findstr /C:.ntp
After you determine the subdomain, you need to ensure VMware is configured correctly. You navigate to the menu and choose Virtual Machine and then Settings from the dropdown menu. The software shows you the following:
Then, click on the Network Adapter under the Removable Devices, and you see the following screen:
You need to make sure that you’re using Internet Sharing, or Share with my Mac. If you’re not using it select it now.
Launch the hosted Linux OS and open a Terminal seesion. Inside the Terminal, you should find the machine’s address as the root address with the
ifconfig utility. The technique follows:
[student@localhost ~]$ sudo sh [sudo] password for student: sh-4.2# ifconfig eno16777736: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 ether 00:0c:29:70:77:64 txqueuelen 1000 (Ethernet) RX packets 34 bytes 4190 (4.0 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 0 (Local Loopback) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Next, you need to edit some files, they assume the VMware Network Gateway is
192.168.147.2 and the machine’s address is “
00:0c:29:70:77:64“. The first file you need to edit is the
/etc/resolv.conf file, and it should look like this:
domain localdomain search localdomain nameserver 192.168.147.2
The second file you need to edit is the
/etc/sysconfig/network file. It should look like this:
# Created by anaconda NETWORKING=yes HOSTNAME=localhost.localdomain GATEWAY=192.168.147.2
The third file you need to edit is the
/etc/sysconfig/network-scripts/ifcfg-eth0 file. It should look like this:
DEVICE=eth0 HWADDR=00:0c:29:70:77:64 ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=dhcp TYPE=Ethernet DNS1=192.168.147.2 USERCTL=no PEERDNS=yes IPV6INIT=no
The last step requires that you reboot the machine or run the
/etc/rc.d/init.d/network to restart the network. I hope this helps those trying to restore their VMware hosted operating systems network connection.
