### Modifying your `hosts` file

After a while, Mail-in-a-Box will be available at `192.168.50.4` (unless you changed that in your `Vagrantfile`). To be able to use the web-based bits, we recommend to add a hostname to your `hosts` file:

After a while, Mail-in-a-Box will be available at `192.168.50.4` (unless you changed that in your `Vagrantfile`). To be able to use the web-based bits, we recommend adding a hostname to your `hosts` file:
|
||||
|
||||
$ echo "192.168.50.4 mailinabox.lan" | sudo tee -a /etc/hosts
|
||||
$ echo -e "192.168.50.4\tmailinabox.lan" | sudo tee -a /etc/hosts
|
||||
or
|
||||
$ sudo sed -i "s/^127.0.1.1.*/192.168.50.4\tmailinabox.lan/" /etc/hosts
|
||||
|
||||
You should now be able to navigate to https://mailinabox.lan/admin using your browser. There should be an initial admin user with the name `me@mailinabox.lan` and the password `12345678`.
