Hamachi
Hamachi by LogMeIn is a cloud‐based, professional‐level application that allows you to easily create a virtual private network (VPN) in minutes. A VPN seems complicated, but Hamachi is not. Unlike traditional software‐based VPNs, Hamachi is on‐demand, giving you secure access remotely to your business anywhere you have an Internet connection. Without protection, the information you send will be out in the open, and anyone interested in intercepting your data can capture it. Figure 6.4 shows an example of a laptop sending an email using VPN to secure transmission over the Internet.
Based on the fact that you are reading this book, I would probably bet you are the tech support for your friends and family. I've used Hamachi to help friends who are not technically savvy to install printers, troubleshoot issues, and share files and games with other friends around the globe. If you have remote computers that you would like to access, this software gives you access to that remote machine, imitating a local area network.
Using Hamachi, you can add friends, family, and mobile employees to a virtual network where you share resources. Your foundational network configuration does not change. With the VPN connection, information you send to your bank, business email, or other sensitive data is protected. When you use a VPN service, the data is encrypted when it gets to the Internet. The destination site sees the VPN server as the origin of the data. It is extremely difficult to identify the source of the data, what websites you visit, or money you are transferring. The data is encrypted, so even if it is intercepted, no one gets the raw data.
To use Hamachi to create a VPN, you must first download the executable file that will allow you to be a client. The term client refers to both the software and any device you've installed the software on. With the correct permission, your client can become a member of any network. The client can be used only with a LogMeIn ID that you create as part of your LogMeIn account when you open and power up the client for the first time. There is no obligation and no credit card required. This ID provides a single sign‐on login experience. Once you're logged in to Hamachi, as you see in Figure 6.5 , you have your IPv4 and IPv6 address.
Every client will have one IPv4 address in the 25.X.X.X range and one IPv6 address. This virtual IP address is globally unique and is used to access any other Hamachi network. As shown in Figure 6.6 , when you set up your network, you will have an option to choose Mesh, Hub‐And‐Spoke, or Gateway.
In a meshed network, every single member of the network is connected to every other member, which makes it easier to relay data. A mesh topology can handle high amounts of network traffic since every device is considered a node. Interconnected devices can transfer data at the same time, and data moves smoothly, which makes this an ideal choice for gaming. The hub‐and‐spoke topology provides more control than the meshed network topology. Hubs are connected to everyone, and you have spokes connected to hubs but not to each other. This is a typical choice for a corporate environment where you have workstations connecting to a server. A gateway network will integrate well with a physical network, giving members access to the physical network. There will be only one gateway, and there can many members.
You must sign up for a free account with LogMeIn to complete the install process, and you will need an email address. When you register, you have improved network management, administration, and the ability to create networks. When you have entered an email and password, you will need to create a client‐owned network. This will include a unique network ID and password so you can manage your new VPN. This peer‐to‐peer VPN is using AES 256‐bit encryption to secure your data. You can share the network ID with up to five people for free, and they can install the client, use the network ID you created, and join your network. If you need more than five members per network, you may want to look at standard or premium packages.
LogMeIn has been tested with many operating systems, and the most current version supports the following:
- Windows Vista (all versions)
- Windows Server 2008 R2 Standard, Business Editions
- Windows 7, 8.1, and 10
- Windows Server 2012
- Mac OS 10.6 (Snow Leopard) and above
- Ubuntu 16.04 and above
- CentOS 7.2 and above
Depending on the topology you have chosen, keep in mind that you cannot assign the Gateway Node functionality to a Mac or Small Business Server.
LAB 6.2: CREATING A CLIENT‐OWNED NETWORK
- From the LogMeIn Hamachi menu in Figure 6.5 , click Network and then Create Network.
- As you see in Figure 6.8 , create a unique network ID. This is the ID that others will use to join your network. An error message will be displayed if the network ID you've entered is already taken.
- Choose and confirm a password that others will use to access your network.
- Click Create. The new network will appear in your client.
LAB 6.3: CREATING A MANAGED NETWORK
- From the LogMeIn website, sign in with your ID.
- From the menu on the left in Figure 6.9 , choose My Networks.
- Click Add Network. Choose a network name, description, and type, and then click Continue. After you click Continue, you cannot change the network type—you will have to delete it.
- You have an option to accept or approve join requests as well as give the network a password.
- Click Continue.
- If you chose the hub‐and‐spoke topology, you will now choose the computer that will act as the hub, as shown in Figure 6.10 . If you chose a gateway topology, choose the computer that will act as the gateway computer. The gateway computer cannot be a member of any other VPN. It is typically a server on the physical network. You can change the gateway at any time.
- Under Add Network, step 3, you select the hub for your network. Click Continue, and on the next screen, step 4, choose the spokes of your network and then click Finish.
To join a network that has been created by someone else, from the Hamachi client, go to Network ➪ Join Network. You will need to know the network ID and the password if one was added.
One of the tools inside the Hamachi web interface gives you the ability to manage computers, files, and users and run reports on sessions occurring in the last 30 days. Under Computers in your web browser, you can add different computers by opening the Computers page and click Add Computer. To add the computer you're sitting at, just download the installer and follow the on‐screen instructions to download and install LogMeIn. To add a computer other than the one you are using, click Add Different Computer ➪ Generate Link. Follow the on‐screen instructions, but be aware this link does expire after 24 hours. This is where others can download and install the software for the client. With the Files menu, you can upload files, share links, and connect storage space for easy access. Figure 6.11 shows the Users section where you can choose to add users to an account and select which computers you want them to have access to.
