I have hosted Microstack, in my Macbook. Everything works fine, I am able to boot instances from the Microstack.
But on the Xenial Server instance I have booted from my Microstack has no internet. I am planning to install docker and create containers.

When I run ifconfig in my Xenial Server instance, this is the result I'm getting.
I am able to both ping router_gateway and router_interface from my xone(Xenial instance). Both 10.20.20.82 and 192.168.222.1.
But I am unable to ping 8.8.8.8 from xone instance. How best I can resolve this issue?
Thanks to https://bugs.launchpad.net/microstack/+bug/1812415.
I was able to resolve this issue by running the following commands in the host (OpenStack) instance:
sudo iptables -t nat -A POSTROUTING -s 10.20.20.1/24 ! -d 10.20.20.1/24 -j MASQUERADE
sudo sysctl net.ipv4.ip_forward=1

Please help me on creating the mgmt network.
This error messages causes from different API version at the keystone.
If your API version is 2? it's not correct, Domain feature is as of Version 3.
so you change your auth URL as follows
export OS_AUTH_URL=http://YOUR_KEYSTONE_IP:5000/v3
And neutron network is not appear as the Ethernet device.
You check the current network list as follow command,
$ openstack network list
And share type network is required Admin authorization.
I'm developing a WordPress site with Vagrant box "vccw-team/xenial64", which can be found at vccw.cc. The website was slow with waiting times that average around 5 seconds, did some googling and many people where pointing at Vagrants synced folder wich is slow in combination with Virtualbox. The solution: nfs. Nfs doesn't exist on Windows so that gave rise to the Vagrant plugin winnfsd.
I installed the plugin and changed the Vagrantfile as such:
config.vm.network :private_network, ip: "192.168.33.10"
config.vm.synced_folder _conf['synced_folder'],
_conf['document_root'], :create => "true", :mount_options => ['dmode=755', 'fmode=644'], type: "nfs"
On vagrant up, I receive this message:
==> vccw.dev: Mounting NFS shared folders...
The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!
mount -o vers=3,udp,dmode=755,fmode=644 192.168.33.1:/D/_projects/Vagrant/vccw/wordpress /var/www/html
Stdout from the command:
Stderr from the command:
mount.nfs: an incorrect mount option was specified
I guess the portion 192.168.33.1:/D/_projects/Vagrant/vccw/wordpress might be wrong because D/_projects/Vagrant/vccw/wordpress exist on the host and not on the guest (192.168.33.1).
Other people managed to get the plugin working. Does anyone know what I'm doing wrong?
Versions:
Vagrant: 2.0.0
vagrant-winnfsd: 1.3.1
Virtualbox: 5.1.26 r117224 (Qt5.6.2)
I enabled DHCP in Vagrantfile like so:
config.vm.network :private_network, ip: "192.168.33.11", type: "dhcp"
But that resulted in the error:
NFS requires a host-only network to be created. Please add a host-only network to the machine (with either DHCP or a static IP) for NFS to work
Then I read in another question on StackOverflow that one can configure a host-only network by using the code below in the Vagrantfile:
config.vm.network :private_network, ip: "192.168.33.11"
config.vm.network :public_network, ip: "192.168.44.12"
config.vm.synced_folder _conf['synced_folder'],
_conf['document_root'], type: "nfs"
I think 192.168.44.0 255.255.255.0 is now the hosted network, derived from ip: "192.168.44.12". It work's now and my WordPress site is faster with a loading time that averages around 3 seconds. I appreciate the improvement but I'll be hawking for other tweaks.

I created a vagrant environment where there is 2 VM's in the private network , i need this because i want them to be able to communicate with each other like application server and database server.So here is my vagrantfile:
Vagrant.configure("2") do |config|
config.vm.define "mac1" do |mac1|
mac1.vm.box = "kaorimatz/centos-6.8-x86_64"
mac1.vm.network :private_network, ip: "192.168.56.101"
mac1.vm.network "forwarded_port", guest: 80, host: 8080
end
config.vm.define "mac2" do |mac2|
mac2.vm.box = "fully-functional"
mac2.vm.network :private_network, ip: "192.168.56.102"
mac2.vm.network "forwarded_port", guest: 80, host: 8081
mac2.vm.synced_folder "./piwik", "/var/www/html"
end
end
now lets say i want to reach only mac2 VM via browser.but i am putting the url like http://localhost:8081 but it says site is not reachable.In that machine when i run the command ifconfig here is the result:

I also added that lines to apache conf :
<VirtualHost *:80>
ServerName mac2.com
DocumentRoot /var/www/html
</VirtualHost>
And i can also listen to the port 8081 like telnet localhost 8081
but i couldnt reach the webserver by any means however i can try.Pls help thank you in advance.
I had the same thing with two vagrant instances using the "kaorimatz/centos-6.8-x86_64" box (even after being fully updated during provisioning):
When I used a different box, I was then able to forward ports. The only change I made was with the Vagrantfile config.vm.box value. I suspect it's a "kaorimatz/centos-6.8-x86_64" issue but I'm not going to investigate the kaorimatz box as the alternative box worked.
(I used the "bmcgonigle/centos68" box.)
#config.vm.box = "kaorimatz/centos-6.8-x86_64"
config.vm.box = "bmcgonigle/centos68"
I had tried the same thing with the private network but had no success with it. I got suspicious of the kaorimatz box when I noticed that I had other vagrant dev configs that forwarded ports with no issues. Best of luck!
I'm new to centos.
When I'm at work I'm able to connect to my centos server from my mac, Now I'm trying to connect from home and I can't.
I've tried pinging google.com and recieved: unknown host google.com .
Maybe it's something with the ip I get from my home router?

P.S-
I'm not sure if it matters, but I'm using Nginx server. I can't restart it also.
Please checks your Centos server file
/etc/hosts.allow
It maybe only allowing certain IPs access to the Centos Box
Your work IP maybe in there but your home IP may not
I have a freedompop Ubee stick that I would like to connect to my beaglebone black (running angstrom with 3.2.0-54-generic kernel). After solving some issues with hotswapping (it's not possible apparently), I am seeing the the interface in using ifconfig. But when I try bringing it up nothing happens:
root#beaglebone:~# ifconfig eth1 up
root#beaglebone:~# udhcpc eth1
udhcpc (v1.20.2) started

Something also strange is that the interface initially has an address:
root#beaglebone:~# ifconfig eth1
eth1 Link encap:Ethernet HWaddr 00:1D:88:53:2F:52
inet addr:192.168.14.2 Bcast:192.168.14.255 Mask:255.255.255.0

RX bytes:2542 (2.4 KiB) TX bytes:9062 (8.8 KiB)
But a few moments ( < 1 minute) later, if I run the same command, eth1 no longer has an address, bcast, etc:
root#beaglebone:~# ifconfig eth1

Under no circumstance (before or after address is stripped in ifconfig) can I ever ping something.
I have tried re-assigning the address, mask, etc, but nothing helps. Bring the interface up or down does not help. I tried manually creating an interfaces file and that didn't help either.
To solve this problem, I had to:
Add an inet dhcp interface in /etc/network/interfaces:
iface eth1 inet dhcp
Add the freedompop as a nameserver in resolve.conf
nameserver 192.168.14.1
Bring up the interface
ifup eth1
