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.

I have neo4j community server edition 3.4.5 and which will be giving me "WebSocket connection to 'ws://localhost:7687/' failed".
I found some solution to work in firefox, chrome, IE but those are temporary solutions which work. but I don't think that just by passing proxy would be a permanent solution.
It is not working if connected to VPN(office network), otherwise working. What could be a reason for this error within an office network? How to resolve this issue.
Any idea or suggestions, Please
There can be several reasons for this issue and I probably need to know more about your setup before I can pin point the problem.
1 check:
Disconnect from the VPN, and open a command prompt (Windows+R then write cmd and press enter)
Use either telnet or putty ( https://www.putty.org/ ) and connect to 127.0.0.1 port 7687:
telnet 127.0.0.1 7687
See if you a response like this:
GET / HTTP/1.0
2 check:
Go to you proxy settings and see if you have a proxy enabled:
Firefox: Preferences/Options > Advanced > Network > Settings
IE: Tools > Options > Connections > Lan Settings
Suggest to turn off your proxy and do the check in check 1 again.
3 check:
Connect to your VPN and do the check 1 part once again
Check for error messages (that you probably would get) and then write in the command prompt:
route print
It should show a line like this:
127.0.0.0 255.0.0.0 On-link 127.0.0.1 xxx
127.0.0.1 255.255.255.255 On-link 127.0.0.1 xxx
127.255.255.255 255.255.255.255 On-link 127.0.0.1 xxx
This ensure that you still have your loop back up and running (probably is ok).
4 check:
Turn off your local firewall with VPN connected (if allowed) and try the check 1 again.
Some firewall rules change connections to "localhost" while connected to a VPN, since the new connection is "corporate" or "public".
If that worked, you need to create a rule in your firewall to allow connection to port 7687 for all addresses, this will fix your problem.
5 check:
Check your neo4j community server to listen to "127.0.0.1" and not "0.0.0.0"
Check your ports open by using netstat
netstat -a -o
It should state something like this
Proto Local Address Foreign Address State PID
TCP 0.0.0.0:7687 machinename:0 LISTENING xxxx
or
TCP 127.0.0.1:7687 machinename:0 LISTENING xxxx
If the server is like the first line, it might be handled by a corporate firewall, but by using the 127.0.0.1 as address it should always be local.
Hopefully that will get you on the way :)
i had same problem, so Let me tell you what i came out with...
the company has a proxy server for all connections, so i change my request from IP to DNS by typing nslookup IP on command prompt terminal.
from: ws://180......:80/socket/test to: ws://mxjuppro22......:80/socket/test
then error gone and now is working like a charm!!!
hope it helps
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'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.
So I have a NGINX server listening on port 8080 with uwsgi on Vagrant box. The config.vm.forward_port 8080, 80 is not working for me. I know that it's recommended to forward on ports higher than 2000, but I need the 80. Is there any issue for that?
I'm using vagrant for development, but I need to make some tests from outside using my domain name on port 80.
Thanks for your help.
When trying to forward ports to less than 1025 vagrant gives me following message which you might have missed:
You are trying to forward to privileged ports (ports <= 1024). Most
operating systems restrict this to only privileged process (typically
processes running as an administrative user). This is a warning in case
the port forwarding doesn't work. If any problems occur, please try a
port higher than 1024.
I was using port forwarding to same port with following configuration:
config.vm.forward_port 80, 80
And then run vagrant up, but when trying curl localhost, it wasn't able to connect to host. But when running vagrant as sudo user sudo vagrant up, then I was able to access the port from my host.
is port 80 available i.e. if you run netstat -an | grep 80, does it show in the list as already being used by another process? Is uwsgi added to the module list of nginx (and did you run make/make install on it)? Have you tried checking if you need to use higher privilenges (perhaps try running as sudo).
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,
