The first time I started up vagrant, the VM was running on 33.33.33.10. After a "vagrant destroy", every time I start up vagrant it runs on 127.0.0.1 even though my Vagrantfile has the following configuration:
config.vm.network :hostonly, "33.33.33.10"
How do I get vagrant to run on 33.33.33.10 again?
127.0.0.1 is loopback interface's home address. Your current machine is always 127.0.0.1.
When you're looking for the proper IP address, run command ifconfig (on UNIX), and look for eth interface.
I guess it's still running at the same address, you just missed the correct IP.
Would you please try running ifconfig eth0 on your virtual machine?
HTH.

When i run vagrant up i get the following error:
Vagrant cannot forward the specified ports on this VM, since they
would collide with another VirtualBox virtual machine's forwarded
ports! The forwarded port to 3306 is already in use on the host
machine.
To fix this, modify your current projects Vagrantfile to use another
port. Example, where '1234' would be replaced by a unique host port:
config.vm.forward_port 80, 1234
I checked and i don't have any processes using port 3306 locally.
I also tried vagrant destroy and vagrant up, didn't help.
vagrant suspend followed by vagrant resume didn't help as well.
What else could be the issue?
What's your command to find the port?
Maybe you can see this. Vagrant Port Collision on Port 80, but Port 80 is not Forwarded in the VagrantFile
Turns out there was a process on my machine running on port 3306.
Running lsof -i :3306 didn't show it, only when i used sudo it did.
Is it possible to dynamically change the MAC address of a VM, using Vagrant?
My host is MacOsX, my guest is Debian8,
and I want to test the following commands (learning about network):
/etc/init.d/networking stop
ifconfig eth0 down
ifconfig eth0 hw ether aa:aa:aa:aa:aa:aa
ifconfig eth0 up
dhclient eth0
The problem is that the first command (/etc/init.d/networking stop) freezes the ssh terminal, so I can't really go forward (I have to vagrant halt, and up again).
And if I remove the first command, then the networking system automatically assigns an IP address to the VM machine as soon as "ifconfig eth0 up" is executed, which defeats the purpose of testing the "dhclient eth0" command (which is actually the one I would like to test).
I'm aware that one can statically change the MAC address at startup (with config.vm.network "public_network" , :mac => "5CA1AB1E0001" for instance), but that's not what I want to do here.
So is dynamic update of the MAC address in a public network with Vagrant possible at all?
You cannot run this command from vagrant ssh as vagrant will use the NAT (eth0) interface to ssh into the VM so if you shut it down the interface, you're cutting your ssh connection.
If you want to run this command you will need to login to the VM directly from VirtualBox (or VMWare if you use this provider) and you will be able to run this command
As you know I use vagrant to manage one vm, when I login to the vm using vagrant ssh, the output shown that I was login from 10.0.2.2. So this IP was my host's IP . But why can not I see it with running ifconfig in my host? That confused me. (But I can found a record about 10.0.2.2 in the host route table)
Any clue will be appreciated!
10.0.2.2 always points to the local host when you are running emulator or vm. So in virtual machine , it refers to the local host (127.0.0.1) as 10.0.2.2. That is the reason you can't see it in ifconfig in your host.
You can find more info in this thread.
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.
I followed the instructions here and was able to succesfully (I think) install the gitlab vagrant virtual machine on OSX 10.8 using virtualbox.
I can do vagrant up to get the VM running, and everything seems to work fine. After that I can do vagrant ssh without a problem. Also, after sshing into the VM I was able to do bundle exec rake gitlab:test, which completed with results being 1584 examples, 0 failures.
I would like to see the gitlab web interface from my OSX host machine. I thought I could just direct my browser to the IP indicated in the VagrantFile (http://192.168.3.14), but that didn't work.
Any ideas?
Also any other usage tips for this setup would be appriciated (things like where the repositories are stored on my host machine so I can back them up, if anyone set the gitlab-vagrant-vm up for external access from either another computer on the network or a remote source, ect.)
You have to connect a second interface for vagrant. To do this you've to edit the VagrantFile.
For example if you want to conenct to the host wifi add the following line after 192.168.3.14
config.vm.network :bridged, bridge: "en0: Wi-Fi (AirPort)"
You also can bridge to the ethernet interface. Use ifconfig on the host machine to determine the right interface. After that the dyndns-server of the host network will assign an IP to the Vagrant-Box. Then you can access GitLab on that IP.
Did you actually start the server? You can do that with
bundle exec foreman start -p 3000
This will start the server on port 3000, you would then access it from the host with
http://192.168.3.14:3000/
Hope this helps,
