I have brought a VM using vagrant.In the config vagrant file, I have given
config.vm.network "forwarded_port", guest: 830, host: 8300.
I'm able to ssh in to the VM by
ssh -p 2223 vagrant#localhost
What if i want to spawn multiple VMs of same kind.How to configure the forwarding ports
You can use auto_correct parameter (see https://www.vagrantup.com/docs/networking/forwarded_ports.html); in case of port collision vagrant can assign another port
config.vm.network "forwarded_port", guest: 830, host: 8300, auto_correct: true
you can check vagrant port to displays information about guest port mappings. The command makes a warning about the value
The forwarded ports for the machine are listed below. Please note that
these values may differ from values configured in the Vagrantfile if
the provider supports automatic port collision detection and
resolution.
just use vagrant ssh to ssh-in into the VM, vagrant will know which port to use.

I am using vagrant with virtualbox as provider. Within my guest system I have nginx installed and configured.
nginx is serving some static files from a folder and exposing them on port 80. That works fine. If I call curl localhost within the guest machine I get the answer I was supposed to receive.
I have a very simple vagrantfile, which you can see below. I forward port 80 to port 8080, but from the host machine I cant access that page via localhost:8080.
I already disabled the firewall in the guest machine without any success.
Vagrant.configure("2") do |config|
# VirtualBox Settings: Give it a little bit more memory
config.vm.provider :virtualbox do |vb|
vb.customize ["modifyvm", :id, "--memory", "768"]
end
# Base Image: CentOS 7.0 x86_64
config.vm.box = "jayunit100/centos7"
# Use Vagrant's default insecure key (~/.vagrant.d/insecure_private_key)
config.ssh.insert_key = false
# Add port forwarding for node-inspector
config.vm.network :forwarded_port, guest: 80, host: 8080 # node-inspector
# Map project directory
config.vm.synced_folder ".", "/server/"
# Provisioning Shell Script
config.vm.provision :shell, :path => "vagrant-setup/base.sh"
end
If I call curl -v 'http://localhost:8080' from the host system I get told that the connection got refused. Any idea what I could do?
I had to disable my firewall on the host machine with iptables -F
I'm using vagrant with multiple machine, it's ever worked normally, but then it just doesn't work again.
My part of Vagrantfile that defining the network:
config.vm.define "app" do |layer|
layer.vm.provision "chef_solo", id:"chef" do |chef|
.....
end
# Forward port 80 so we can see our work
layer.vm.network "forwarded_port", guest: 80, host: 9999
layer.vm.network "private_network", ip: "10.10.10.10"
end
It's a standar configuration and I only have that vm. But when I tried to vagrant up, it shows error:
Vagrant::Errors::NetworkCollision: The specified host network collides with a non-hostonly network!
This will cause your specified IP to be inaccessible. Please change
the IP or name of your host only network so that it no longer matches that of
a bridged or non-hostonly network
How to fix it?
Apparently my office just changed the network configuration. By changing 10.10.10.10. to other blok (e.g 10.0.0.100), it workedagain. Sorry.
I have Vagrant in use for one box profile. Now I want to use Vagrant for another box (b2), but it says that bioiq's instance is consuming the forwarded port 2222 (which it is).
Now, if I configure b2 with the below, Vagrant still tries to use 2222.
Vagrant.configure("2") do |config|
config.vm.box = 'precise32'
config.vm.box_url = 'http://files.vagrantup.com/precise32.box'
config.vm.network :forwarded_port, guest: 22, host: 2323
# Neither of these fix my problem
# config.vm.network :private_network, type: :dhcp
# config.vm.network :private_network, ip: "10.0.0.200"
end
I've tried various ways from other SO questions to set the :forwarded_port (see here and here). I also tried this Google Group post, to no avail. I keep getting this message.
Vagrant cannot forward the specified ports on this VM, since they
would collide with some other application that is already listening
on these ports. The forwarded port to 2222 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.network :forwarded_port, guest: 22, host: 1234
Sometimes, Vagrant will attempt to auto-correct this for you. In this
case, Vagrant was unable to. This is usually because the guest machine
is in a state which doesn't allow modifying port forwarding.
I don't know why Vagrant consistently ignores my directives. The posted configuration doesn't work. Has anyone overcome this?
In case of ssh port, Vagrant solves port collisions by itself:
==> ubuntu64: Fixed port collision for 22 => 2222. Now on port 2200.
However, you still can create unavoidable collision by:
Creating first vagrant env (it will get port 2222 for ssh)
Suspend that env (vagrant suspend)
Create second vagrant env (it will again get port 2222, since it is now unused)
Try bringing first environment up again by vagrant up
You will get the error message you are getting now.
The solution is to use vagrant reload, to let vagrant discard virtual machine state (which means it will shut it down the hard way - so be careful if you have any unsaved work there) and start the environment again, solving any ssh port collisions on the way by itself.
I've just run into a problem on current versions of Mac OSX (10.9.4) and VirtualBox (4.3.14) where the default ssh port 2222 is both unused and unbound by vagrant up. It was causing the sanity check ssh connection to timeout indefinitely.
This isn't the exact same problem, but an explicit forward resolved it:
config.vm.network :forwarded_port, guest: 22, host: 2201, id: "ssh", auto_correct: true
This suggestion comes from a comment on the Vagrant GitHub issue 1740.
It's not clear whether the port forwarded to 22 is being detected or if the ID is used, but it's working for me.
My computer is Windows 10, and I solved this problem by disabling the 8080 port. because it is said that "the forwarded port 8080 is already in use on the host machine."
So I edit the Vagrantfile and comment the port 8080.
We use vagrant to setup a VirtualBox image with Ubuntu Linux. It has private network enabled, and a number of ports are forwarded - here are some snippets from our Vagrantfile:
config.vm.network :private_network, ip: "192.168.33.10"
config.vm.network "forwarded_port", guest: 3306, host: 3306 #mysql
...
config.vm.network "forwarded_port", guest: 8098, host: 8098 #riak http
config.vm.network "forwarded_port", guest: 8087, host: 8087 #riak pb
This works allright when the VM is started.
But after the host machine has been suspended for a while (more than a brief period) and resumes, then the port forwarding does not work any more.
Everything responds fine on the allocated private network address, 192.168.33.10, but not on localhost where the attempt just hangs.
Any ideas for a solution?
Specs:
Host OS: Mac OS X, version 10.9 "Mavericks"
Guest OS: Ubuntu 12.04, precise64 (standard box from vagrantup.com)
Vagrant 1.4.0
VirtualBox version: VirtualBox 4.3.4 r91027
Virtual Box > Machine Settings > Network
Adapter 1:
Attached to: NAT
Cable Connected : True
Port Forwarding:
TCP, HostIP=, HostPort=3306, GuestIP=, GuestPort=3306
TCP, HostIP=, HostPort=8098, GuestIP=, GuestPort=8098
TCP, HostIP=, HostPort=8087, GuestIP=, GuestPort=8087
TCP, HostIP=127.0.0.1, HostPort=2222, GuestIP=, GuestPort=22
I found a similar question, but can not seem to use the same answer: VirtualBox port forwarding not working with NAT adapter
I have installed Vagrant in my Window XP, and in my Vagrantfile I have:
Vagrant::Config.run do |config|
# Setup the box
config.vm.box = "lucid32"
config.vm.forward_port 80, 8080
config.vm.network :hostonly, "192.168.10.200"
end
But I see no sign of my vagrant box when I type "http://192.168.10.200:8080" in browser.
IP address of the virtual box is correct, because from within the vbox, I have:
vagrant#lucid32:~$ ifconfig
....
eth1 Link encap:Ethernet HWaddr 08:00:27:79:c5:4b
inet addr:192.168.10.200 Bcast:192.168.10.255 Mask:255.255.255.0
There seem to be no firewall problem because if I type
vagrant#lucid32:~$ curl 'http://google.com'
it works fine.
I have read Vagrant's port forwarding not working
and tried:
vagrant#lucid32:~$ curl 'http://localhost:80'
curl: (7) couldn't connect to host
and also
vagrant#lucid32:~$ curl 'http://localhost:8080'
curl: (7) couldn't connect to host
So, looks like port forward is not working...
If you know what I can do so I can access my vbox from host browser, can you help me?
Thanks in advance
If you just started a Vagrant box with this Vagrantfile, there is nothing more than an empty Ubuntu Lucid, which does not run any service yet. So there is nothing served on port 80, this is why there is nothing to see either from inside the box on port 80 or the host machine on 8080.
For you Vagrant machine to provide some services (such as a web server on port 80), you have to do some provisioning. You can do it manually or using Chef or Puppet which are hooked into Vagrant's up process.
I had a similar problem. Sometimes using port forwarding for ports below 2000 is a problem. What worked for me is choosing ports that are above 2000. So my vagrantfile now looks like:
config.vm.network :forwarded_port, host: 4500, guest: 9000
Typing localhost:4500 on my host machine now just works fine. It seems like you are on an older version of vagrant than mine, so you can edit your vagrant file to something like
config.vm.forward_port 9000, 4500
Now typing localhost:4500 on your host machine should work fine.
Good luck,
