I like to have a separate virtual network interface on Mavericks, so I can have static IP between the Guest to Host setup of VirtualBox. In xUbuntu, i could do that by updating /etc/network/interfaces:
#The secondary network interface
auto eth1
iface eth1 inet static
address 10.88.12.4
netmask 255.0.0.0
How to do the same in Mac Mavericks? I did try using 'system preferences'->Networks->Actions Menu->Manage Virtual Network Interfaces->Add New VLAN, however, it is giving 'Status: Cable Unplugged'. How to make virtual network interface on Maverick? Thank You
The solution was letting VirtualBox create the virtual network interface by creating "Host Only Network" by going VirtualBox VM -> Preferences -> Network -> Host Only Networks -> Add New and set up the IP/Subnet at that time
Afterwards, check the new virtual network interface by typing "ifconfig" in the command line. It will desiplay something like:
vboxnet0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
ether 0a:00:27:00:00:00
inet 10.88.12.0 netmask 0xff000000 broadcast 10.255.255.255

My computer has a Windows 10 and I was following through Microsoft 98-366 Network Fundamentals book.
It had me to open Windows Powershell and type
New-NetIPAddress -InterfaceAlias "Local Area Network" -IPv4Address 192.168.1.101 -PrefixLength "24" -DefaultGateway 192.168.1.1
Then I got the error that it can't find a parameter with the name IPv4Address. It'ns not a typo though, because above was directly copied from the book.
So when I looked up the documentations on New-NetIPAddress it seemed -IPv4Address is not an option and instead I have to use IPAddress. So I tried the below
New-NetIPAddress -InterfaceAlias "Local Area Network" -IPAddress 192.168.1.101 -PrefixLength "24" -DefaultGateway 192.168.1.1
Then I got a new error saying
New-NetIPAddress : Invalid parameter InterfaceAlias Local Area Network
but InterfaceAlias does exist in the documentations, so I'm not sure what causes it to be invalid.
Thanks in advance for any kind of help.
Additionally, the documentation I looked up was this:
Net-NetIPAddress
I think the InterfaceAlias is not valid.
First look at all the network interfaces using the command Get-NetIPInterface. Here is the output in my PC:

Re-check by reading all properties with Get-NetIPInterface | Format-List * will help you identify which is the correct network interface you are looking for.
I have binded two ips with single nic (Network Interface Card) in debian this way.
step 1:
vim /etc/network/interfaces into the following format:
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.100
netmask 255.255.255.0
gateway 192.168.1.1
network 192.168.1.0
broadcast 192.168.1.255
auto eth0:1
iface eth0 inet static
address 192.168.1.101
netmask 255.255.255.0
gateway 192.168.1.1
network 192.168.1.0
broadcast 192.168.1.255
Now 192.168.1.100 and 192.168.1.100 are all binded with my local nic.
step2:
vim /etc/network/ifstate into the following format:
lo=lo
eth0=eth0
eth0:1=eth0:1
It is time to restart my network now.
/etc/init.d/networking restart
[....] Running /etc/init.d/networking restart is deprecated because it may not r[warnble some interfaces ... (warning).
[....] Reconfiguring network interfaces...RTNETLINK answers: File exists

done.
ifdown eth0 && ifup eth0
ifdown: interface eth0 not configured
RTNETLINK answers: File exists
Failed to bring up eth0.
The two ip have been binded with single NIC when to reboot my pc.
I want to know the proper way to restart networking not to reboot it.
Typically to stop/start/restart the network interface on Debian:
/etc/init.d/networking stop
/etc/init.d/networking start
/etc/init.d/networking restart
To verify changes after making changes and restarting:
ifconfig -a

I have a Ubuntu host and an Ubuntu guest. I want to achieve that my host traffic is tunnelled through my guest. Thus enabling me to do analysis on the host traffic from the guest. I am assigning two interfaces to the guest (in addition to the built in NAT interface which is provided by Vagrant). I am creating a bridge interface on the host called br0. One of the guest interfaces is connected via bridging to eth0 (the host interface which is connected to the Internet) and the other guest interface is connected via bridging to the host br0 interface. On the host I am deleting my default gateway and adding a new one with:
route del default
route add default dev br0
After that I can vagrant ssh into my guest and set up a bridge interface there as well with.
brctl addbr br0
brctl addif br0 eth1
brctl addif br0 eth2
After this setup the host traffic should be routed through the guest. If I run
tcpdump -vni br0
inside the guest I can see packets but I can't connect to the Internet. There is something missing. Any ideas?
I had to enable IPv4 forwarding in the guest.
Edit /etc/sysctl.conf to enable forwarding permanently:
net.ipv4.ip_forward = 1
Run this to activate the setting without a reboot:
sysctl -p /etc/sysctl.conf
I have win 7 OS on my laptop, and linux(debian 7) inside vmware. I have set the debian to have bridged connection with the network. I am connected by wifi, and if the wifi modem is being restarted the local ip address of the debian changes, e.g. from 192.168.0.106 to 192.168.0.102. Is there a way to set the local ip address, so it will always remain the same ?
Thanks
You have to change your /etc/network/interfaces like this
and after that remember to restart your service using
sudo service networking restart
ok, found the solution
here is the source
http://www.cyberciti.biz/tips/howto-ubuntu-linux-convert-dhcp-network-configuration-to-static-ip-configuration.html
basically for debian
1) vim /etc/network/interfaces
2) comment/delete this line iface eth0 inet dhcp
3) add this
iface eth0 inet static
address 192.168.1.106 # this is the ip address you want to assign
netmask 255.255.255.0
network 192.168.1.0
I'm trying to access my Tomcat instance on OSX with Windows 7 via VirtualBox.
My network settings on VirtualBox:
Adapater 1: Bridged Adapter
Name: en1: Wi-Fi (Airport)
Adapter 2: Host-only Adapter
Name: vboxnet0
my ifconfig -a from OSX:
vboxnet0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
ether 0a:00:27:00:00:00
inet 192.168.56.1 netmask 0xffffff00 broadcast 192.168.56.255
I can ping my OSX box from Windows 7, but when I try to visit http://192.168.56.1:8080 I simply get an error that looks like I'm not connected.
Any ideas? Am I missing something in my OSX settings?
edit:
netstat -lan |grep 8080:
tcp46 0 0 *.8080 *.* LISTEN
Problem solved.
Adapter 1: NAT
Adapter 2: Disabled
