How do I access the host from the guest in vagrant? - vagrant

I have a Ubuntu 14.10 64-bit box running in vagrant on a Windows 8.1 64-bit host.
In this book it is said that if I set a host-only network, I should be able to access the host with the same ip address as the guest if I change the last octet to 1:
config.vm.network "hostonly", "192.168.33.10"
In the latest vagrant, hostonly is not available any more, so I tried setting it to private_network.
However, I am not able to ping 192.138.33.1 from my guest.
How do I access the host from the guest when using vagrant?

Ping doesn't work. You can connect your host server by this way
ssh user#192.138.33.1
If your host server has ssh service enabled.

Virtualbox and host connection problem: unable to ping and ssh connection from host to VM, but VM to Host ping and ssh connections working

I have been searched many resources, but I can't solve this problem.
Firstly, I want to clarify that, my windows 10 all firewall options are turned off (also turned off ubuntu server 16.04)
Windows firewall settings
this is my host machine ip configuration (windows 10)
Host machine IP
this is my NatNetwork configuration in Virtualbox
NatNetwork configuration in Virtualbox
this is my port forwarding configuration in NatNetwork
Port Forwarding configuration
I want to mention that when I use 127.0.0.1 Ip address as a port forwarding HOST IP address. this is not working also, but I can ping from my host to 127.0.0.1 IP address.
this is my ubuntu_server 16.04 ip configuration
Ubuntu_server 16.04 IP configuration
When I ping from ubuntu_server to my HOST (from 172.31.0.4 to 192.168.0.110), I can ping
from VM to HOST ping
But I can't ping from HOST to VM (from 192.168.0.110 to 172.31.0.4), I get the request timed out.
enter image description here
So, I can't ping from HOST to VM, please help me solving this problem
I have a problem VM and HOST connection.

How do I access an Oracle VM in my local network from another device?

I have following setup:
Windows 10 desktop with VirtualBox Oracle VM running
MacBook M1 which needs access to the Oracle VM
Windows desktop and MacBook are on the same local network
From my MacBook i'm able to ping my windows desktop's IP, but not the IP of the VirtualBox VM.
On the Oracle VM's settings I have a bridget adapter configured.
Is there a way to connect from my MacBook to the Oracle VM hosted on my Windows desktop in the same network?
Thanks in advance!
It depends on what type of network adapter you defined to the VM. In order to access from other machines on your LAN, you will need a BRIDGED adapter. Further, you will need to configure it (in the guest OS) with a manually assigned IP address in the same subnet as your other machines. My guess is you just took defaults and have only a NAT adapter.
I've built scores of VM's under VBox, and always create two adapters. The first is a NAT adapter, which allows my vm to access the internet - critical for downloading and installing packages with 'yum'. The second adapter is either HOSTONLY or BRIDGED. I use HOSTONLY if I want the VM to be totally isolated from the LAN and only accessible by the host or other vm's on the host. I used BRIDGED if I want to access the vm from other machines on the LAN. Either way, the BRIDGED or HOSTONLY need to be configured with a manually assigned ipv4 address in the same subnet as the host os.
I always create the NAT as the first adapter, and the BRIDGED or HOSTONLY as the second. On the os, the first (NAT) shows up as 'enps03' and the second as 'enps08'. I then configure enps08 with the following:
First, run the command below to set up the IP address. (substitute your chosen IP, but keep the '/24')
$ nmcli con mod enp0s8 ipv4.addresses 192.168.0.200/24
Next, configure the default gateway as shown - again, the first three octets of your subnet.
$ nmcli con mod enp0s8 ipv4.gateway 192.168.0.1
Next , set the addressing to static.
$ nmcli con mod enp0s8 ipv4.method manual
Set to start on boot
$ nmcli con mod enp0s8 connection.autoconnect yes
To save the changes, run the command
$ nmcli con up enp0s8
Reboot and check with ‘ifconfig’.

Ubuntu - vagrant access from another computer

I have recently learned how to setup a virtual machine using vagrant (virtualbox), and I know how to access it from a web browser via the local adress such as 192.168.x.x:9292 since 9292 is the default gate. But I would like to access the server from another computer locally.
My question is if I could access it via cmd as I connect to it on my own with the command vagrant ssh but from another computer via a command like vagrant ssh 192.168.x.x?
As far as I understand you have to use external programs or setup something inside the vagrant environment? Is there a simple way to access the server or is it password protected? If I setup a website I can access that for example from another local machine but can I access files on the server (from another computer)?
I found how to connect to another computer locally by entering the vagrant environment, vagrant up --> vagrant ssh. And connected to another computer by typing in ssh vagrant#192.168.x.x where 192.168.x.x is the local address to the computer. The vagrant asks for a password and you type in the default password which I believe is vagrant and then you are connected to the other vagrant instance.
Assuming you have virtualbox provider for Vagrant you can achieve this by doing bridging the VBox network interface with Host.
Use this in Vagratfile (for public/private)
For Public
Vagrant.configure("2") do |config|
config.vm.network "public_network",
use_dhcp_assigned_default_route: true
end
For Private
Vagrant.configure("2") do |config|
config.vm.network "private_network", type: "dhcp"
end
above code will create IP in the range of Host network and using this you can access the file server from another machine.

How to bind external ip to Vagrant VM?

I have external IP address. I added it to my eth0 interface of host machine. I can successfully ping it. I want to run VM using Vagrant and set my external IP to it (I want to call my VM just like a simple VPS using this external IP address). I have next line in Vagrantfile for this:
node.vm.network "public_network", ip: myExternalIP
After my machine start I see eth2 interface inside my VM with my external IP as inet addr. But I can't get access to any open port on my vm using this IP address. Maybe I don't understand idea of public_network in Vagrant. How to bind external ip to my Vagrant VM?
Update: As I understood vagrant set default gateway of VM to interface under NAT. Due to NAT packages cant be sent from VM to external world through bridged interface.
I got it working this way:
config.vm.network "public_network", ip: "192.168.0.17"

How can I access a vagrant guest from another virtualbox guest?

The scenario is that my dev environment is on a Vagrant box on my laptop (host) and I would like to do browser testing in a vitualbox vm, so I need to see one vm from another.
The vagrant box's port is :8080 which is forwarded to the host on the same port :8080. So I can see the server from the host at localhost:8080
Which address should I be using for the browser testing vm?
The testing vm's default gateway?
The vagrant vm's ip?
The host's virtual network ip?
And should I be using a NAT or host only adapter on the browser testing vm?
That makes for a lot of combinations, all of which I believe I have tried. What else do I need to understand here?
In your use case, you should be using Bridged networking (Public Network in Vagrant). If the VMs reside on the same host, you can even use internal (Private Network in Vagrant).
If using Public Network, the VM's 2nd NIC will be able to obtain an IP address from the DHCP server in your network (e.g. your home router).
Simply add the following code block in your Vagrantfile and do a vagrant reload
Vagrant.configure("2") do |config|
config.vm.network "public_network"
end
You should be able to get the IP address by using vagrant ssh and ifconfig / ip addr show.
In case you don't want to go with public_network just like me then you should do the steps below using private_network:
Open Vagrantfile from your project root
Search for config.vm.network
Add this line config.vm.network "private_network", ip: "192.168.33.10". Remember this is not the IP of your base machine it's a virtual-box IP address and your machine IP should be different. You can say it's a fake IP address so change it to anything else like 192.168.30.20.
Reload your vagrant using vagrant reload.
Now go to your other virtual guest in my case it's the Windows Guest 2. My base is Linux Mint Vagrant box is on Ubuntu Guest 1. Open C:\Windows\System32\drivers\etc\hosts file as admin and do the above IP's entry in there like 192.168.33.10 local.youralias.com. And save the file, after that you can now browse the site now at http://local.youralias.com/.
In case your guest 2 is also Linux just edit this file sudo vi /etc/hosts, and add this line at top of it 192.168.33.10 local.youralias.com. Now save and exit and browse the URL :)
Enjoy! Happy coding.
Adding to accepted answer, you can actually set IP and specify which network interface to use.
My setup on linux box via wifi and static IP:
You can find your wifi interface name by running ifconfig command.
Vagrant.configure("2") do |config|
config.vm.network "public_network", :bridge => 'wlp8s0', ip: "192.168.1.199"
end
This may have many source cause. In my case, I use vagrant fedora boxe.
I tried:
First using the private_network that I attached to a host only adapter and launched httpd service to test the connection between guest and host
config.vm.network "private_network", type: "dhcp", name: "vboxnet2"
config.vm.network "forwarded_port", guest:80, host:7070
but I was not able to ping my guest machine from the host and could no telnet the httpd service opened
Second using public_network and launched httpd service to test connectivity
config.vm.network "public_network", bridge: "en0: Wi-Fi (AirPort)", use_dhcp_assigned_default_route: true
I could ping my guest from my host but I could not telnet the httpd service.
For this two use case, the issue was that the port 80 on the fedora guest host was blocked by the firewall. Here is what fixed the issue and get all working for both privat_network and public_ntwork:
firewall-cmd --permanent --add-port 80/tcp #open the port permanently
firewall-cmd --zone=public --permanent --add-service=http
firewall-cmd --list-port # list to check if the port was opened
systemctl stop firewalld # stop and open the firewall service
systemctl start firewalld
Old question, new answer: [disclaimer: i am not a vagrant expert]
both solutions might work but the solution in the "vagrant way of thinking" is that some component in your guest (rinetd?) should forward any requests to unknown ports to the host. From the host the request could then be mapped (via vagrant port forwarding) to a services that is running in the other guest.
So, to resume:
1.in guest-1 we do localhost:1234. Guest-1 will detect that this port is not available and forward to host
2. the host will check the vagrant port forwarding and forward to guest-2
3. in guest-2 we have some nice service listening to post 1234
4. done.
