Can't `ssh` onto Private Network

Question

Given the following Vagrantfile:

# -*- mode: ruby -*-
# vi: set ft=ruby :

VAGRANTFILE_API_VERSION = "2"

Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
  config.vm.box = "centos_64"
  config.vm.host_name = 'web'
  config.vm.network "private_network", ip: "192.168.50.4"
end

Why can't I ssh onto the guest from the host?

$ ssh vagrant@web -p 22
ssh: connect to host web port 22: Connection timed out

But using vagrant ssh works:

$ vagrant ssh
Last login: Tue Mar  4 21:29:24 2014 from 10.0.2.2
[vagrant@web ~]$

As expected, I can ping the IP Address from the guest. But I can't ping from the host.

I'm confused as to why it's happening since my setup does not look different from this configuration.

Answer 1

First, vagrant ssh uses the forwarded port and not the private network address. You can get the configuration with vagrant ssh-config.

Is the name "web" really resolving to the specified IP? Can you ping/connect using the IP instead of the name? If not, verify that you don't have other VMs or external networks with the same address. Also some VPN products mess up the routing.
