Vagrant port forwarding not working. Cups not accesible from host

问题

So I'm working with vagrant and I'm trying to use it as a printing server. I installed cups.

Internally everything works just fine. I can even make a quick curl to my localhost:631 (cups port inside my vagrant) and there's everything.

The thing is I cant access it in any way I try from the host machine.

Obviously I forwarded the port and I've tried with several ports. I've also tried with Debian squeeze and Ubuntu 12.04. Here is my current Vagrantfile

Vagrant.configure("2") do |config|                                              
  config.vm.box = "guruDebian"
  config.vm.network :forwarded_port, guest: 80, host: 8080
  config.vm.network :forwarded_port, guest: 631, host: 6363   ## HERE IS CUPS           
end

Any ideas?

回答1:

I think what you will find is that the default cups config file is locked down to only work from localhost for security reasons.

Inside your Vagrant VM open the /etc/cups/cupsd.conf file and change the following line:

Listen localhost:631

to

Listen 0.0.0.0:631

That should allow you to connect from any host.

Have you tried accessing port 8080 of guest to your host? if no, and the services inside guest are running. then its a firewall issue in guest.

Try to turn firewall temporarily

service iptables off

then try to access it again from host.
