Network configuration - connection to your MinIT
The MinIT has two interfaces that we support for data transfer. These are the:
- Ethernet port - direct to interface or LAN
- Wi-Fi - direct to interface
Networking with MinIT. Blue lines indicate a connection via the internet. The black line indicates a wired connection. The curved waves indicate a wireless connection. The computer on the LAN (B.) can be used to update MinIT - this is the supported method. You can configure MinIT using the Wi-Fi connected device (A.), however, network compatibility issues may inhibit the updating of your MinIT.
Internet connection:
The suggested update method considers a configuration that requires an ethernet connection to the Local Area Network (LAN) from the MinIT. The LAN is connected to the internet, which enables updating of MinKNOW on the MinIT.
Interface connection:
An interface, such as a laptop/mobile device/computer, can be wirelessly connected to the MinIT (i.e. MinIT in Hotspot mode). Alternatively, the MinIT may be accessed and controlled by a computer on the LAN.
Note: Other configurations exist:
- Ethernet-desktop/laptop computer to control the MinIT - no internet
- MinIT Wi-Fi (Client) to a router and desktop/laptop Wi-Fi to a router, which is itself connected to the internet
- It is possible to adapt other data connections through the USB 2.0/3.0 ports, however, Oxford Nanopore Technologies cannot advise or support this use.
The latter three suggestions are not supported uses of MinIT's technology by Oxford Nanopore Technologies.

Secure Shell (SSH) on a MinIT
If you need to do configure your device, using parameters that are not available through the Admin interface, you will need to connect via an SSH terminal:
- Connect to the MinIT using the instructions that are specific for your operating system. e.g. The Wi-Fi Single Sign-on (SS)ID is the MinIT serial number e.g. mt-100007 and the password for the access point is WarmButterflyWings98.
- Connect to the MinIT using an SSH client. The Hostname is the serial number of the MinIT or IP address by which the MinIT is connected to your device e.g. Wi-Fi or Ethernet.
If you have a Linux computer, then an SSH client, called SSH, is already available. For Windows, we recommend Bitvise for SSH and data transfer or PuTTY to just SSH. A program called Terminal is already installed on macOS that can be used for SSH access.
To SSH in using a terminal, you should:
1 - Enter default username and password in the terminal or Bitvise/PuTTY GUI. These are:
Username:
minit
Password:minit
Note: You will be prompted for these in the terminal.
2 - To access the MinIT by the terminal, you must enter the command:
ssh [username]@[MinIT serial number]
or
ssh [username]@[IP address of MinIT]
Note: The
username
isminit
and you can enter the hostname as
1. the MinIT serial number e.g.mt-100007
or
2. the Wi-Fi/Ethernet connection IP address e.g.10.42.0.1
for a Wi-Fi link or as indicated by the IP address shown in the Admin interface (as of MinKNOW 19.12)Note: Also, if using Bitvise or PuTTY, you will already be using SSH, once you have logged in via the software's GUI.

Static vs dynamic IP addresses - SSH
If you want to enable static IP addressing on the Ethernet port, then:
sudo nmcli c down dhcp sudo nmcli c up static
If you want to enable dynamic IP addressing on the Ethernet port, then:
sudo nmcli c down static sudo nmcli c up dhcp
The default IP address for the static profile is
192.168.0.1/24
. The IP address can be changed along with any other parameter of the connection using the editor:sudo nmcli c edit static
-
Changing the default password
The default password should be changed at the earliest possibility to ensure the security of your MinIT.
To change the password.
1. Login to the minit using username and passwordminit
in the SSH/Terminal.
2. Use the commandpasswd
to provide the necessary options for changing the default passsword.
3. The existing password isminit
; however, please record your new password safely, as if it is forgotten the user will have to perform a factory reset and risk losing data or risk losing access to the device.
