MacOS® has a feature that allows one or more folders to be shared with computers on the local network. It is also possible to use this function with your MyCrypNet network to perform secure, simple and fast exchanges between your different machines.

It is based on SMB.

We’ll see the different configuration steps to perform.

If you want more general informations on how does a file sharing works or how to install it on other operating systems, check this article.

You need to have a MyCrypNet network set up. Check this help page in order to create one.

Step 1/3: Create a user account

For security reasons, files sharing needs authentication, ie you have to enter a username and password when you accede to a shared directory.

The best way to do this is to create a local user account on the machine that will share a folder. This user account will be called by the one who wants to accede to this shared folder. Obviously it’s possible to create as many user accounts as you want to.

The first step is to accede the System Preferences and then “Users & Groups”.

You must click on the padlock at the bottom left to identify and unlock the user account add feature. Then you can click on the “+” button to create a new account.

All you have to do is enter the informations of this account and validate it.

We will call the created account ALICE and the password ALICE-PASSWORD (the naming convention in uppercase is explained here).

The identifiers of this new user account have to be communicated to the person who will, later on, accede to the shared folders. Always prefer a secure communication method (encrypted message, etc.).

Step 2/3: Enable the file sharing feature

Go to System Preferences and then “Sharing” to enable this feature.

You must check “File Sharing” in the left column, then access “Options”.

To set up a cross-platform files sharing, check “Share files and folders using SMB” and select the user(s) of the machine whom you will allow remote access to.

Step 3/3: Configure the files sharing

On the folder you want to share (we will call it SHARE-NAME), you must right-click and then “Get Info”. You also can do ctrl-click and then “Get Info”.

At this point we can check the box “Shared folder” which makes this folder available in a network share.

You also have to configure the permissions on this folder, at the bottom of this window.

It’s possible to add permissions to a user through the “+” button and configure its rights (read, write or both).

This makes it possible to use the built-in file-sharing feature of MacOS®, without installing third-party software and preserving all the advantages of your MyCrypNet private network: security, speed and simplicity.

Global structure

A MyCrypNet network is made of MyCrypNet accesses installed on different devices.

The MyCrypNet accesses identify the devices on the MyCrypNet network.

A devices can have several accesses. It can be used by several users with, each, his(her) own MyCrypNet access for him(her) alone. But also, a common access can be installed on the device, available for all the users of the device.

Accesses in a MyCrypNet network can be delegated.

How to install MyCrypNet

Here are the tutorials allowing to install a MyCrypNet access on the main operating systems:

This tutorial shows how to install MyCrypNet on Android™
This tutorial shows how to install MyCrypNet on IOS®
This tutorial shows how to install MyCrypNet on Linux®
This tutorial shows how to install MyCrypNet on Mac OS®
This tutorial shows how to install MyCrypNet on Windows®

Alternate configurations

If you want to adapt the accesses configuration to particular networks constraints (firewalls, routers…) You can edit the configurations with the help of the following tutorials:

Delegation

If you want to delegate parts of your MyCrypNet network, here is the tutorial showing you how to do:

How to delegate a MyCrypNet access

And here is the tutorial with the provided options to the delegated:

How to use the delegation for a MyCrypNet access ?

If you want to detach completely an access from the network, isolate it from its network to use it as a simple anonymous tunnel, here is the tutorial:

How to use a MyCrypNet access as a simple tunnel ?

Security

If one of your devices is compromised, lost or stolen, it is strongly recommended to revoke the access installed on it to avoid a potential intrusion on the network.

Here is the revocation tutorial:

What to do in case of theft or lost with MyCrypNet ?

If you want to reinforce, even more, the access security, you can add a two-factor authentication to it:

Also, if you want to reinforce the accesses management interface (available on Limawi) and your payment informations handled by Limawi as well, you can add a two-factor authentication too:
