1.3 Remote access

We connect to your personal computer by using the Secure Shell.

Find your PC

Your Personal Computer is starting and gets a new address from your home network. Give it a few minutes to come to life.

  • On your regular computer, open the Terminal (also known as "command line")

    • On Linux/macOS with a graphical interface, search on the application list, "Terminal" or press the keyboard shortcut Ctrl + Alt + T

    • On Windows, search on the application list cmd

  • Try to ping using the IP assigned to your MiniBolt in the before step

$ ping 192.168.x.xxx

Example of expected output:

PING ( 56(84) bytes of data.
64 bytes from icmp_seq=1 ttl=64 time=2.44 ms
64 bytes from icmp_seq=2 ttl=64 time=1.75 ms
64 bytes from icmp_seq=3 ttl=64 time=1.61 ms
64 bytes from icmp_seq=4 ttl=64 time=1.58 ms
  • If ping command fails or does not return anything, you need to manually look for your PC

  • You should now be able to reach your PC, with the IP address like 192.168.x.xxx

Access with Secure Shell

Now it’s time to connect to the MiniBolt via Secure Shell (SSH) and get to work. For that, we need an SSH client.

Install and start the SSH client for your operating system:

  • Windows, 2 options:

    • Download Putty 64-bit x86 or 32-bit x86 version depending on your OS architecture. Source

      • Start Putty, to the left tree, select "session", in the "Hostname (or IP address)" box, type [email protected], port 22 to the left box.

      • Press the button OPEN, when a "PuTTy security alert" banner appears, press the "Accept" button, and finally type your password [A].

    • Download the MobaXterm Portable Edition or Installer Edition version depending on whether you want to install it permanently or not.

      • Start MobaXterm, 2 options:

        • If you want to save the session for later: on the top menu, click on "Session" -> "New session" -> Select "SSH".

          • Enter MiniBolt IP address (192.168.x.xx), check "specify username" and enter to the right "temp", keep port "22" selected to the right.

          • Press the button OK, when a "Connexion to..." banner appears, press the "Accept" button, and finally type your password [A].

        • Otherwise, select on the dashboard the "Start local terminal" button and type directly on the terminal ssh [email protected].

  • MacOS and Linux:

    • From the native terminal, type: ssh [email protected]

    • Use Putty, simply from the native terminal type sudo apt install putty and start it by typing putty, follow the same Putty instructions as before for Windows.

Note, connection details:

> hostname: your MiniBolt IP address like: 192.168.x.xxx
> port: 22
> username: temp
> password: password [A]

The command line

We will work on the command line of the PC, which may be new to you. Find some basic information below. It will help you navigate and interact with your PC.

You enter commands and the PC answers by printing the results below your command. To clarify where a command begins, every command in this guide starts with the $ sign. The system response is marked with the > character.

Additional comments begin with # and must not be entered.

In the following example, just enter ls -la and press the enter/return key:

$ ls -la
> example system response
# This is a comment, don't enter this on the command line
  • Auto-complete commands: You can use the Tab key for auto-completion when you enter commands, i.e., for commands, directories, or filenames.

  • Command history: by pressing ⬆️ (arrow up) and ⬇️ (arrow down) on your keyboard, you can recall previously entered commands.

  • Use admin privileges: Our regular user has no direct admin privileges. If a command needs to edit the system configuration, we must use the sudo ("superuser do") command as a prefix. Instead of editing a system file with nano /etc/fstab, we use sudo nano /etc/fstab.

    For security reasons, service users like "bitcoin" cannot use the sudo command.

  • Using the Nano text editor: We use the Nano editor to create new text files or edit existing ones. It's not complicated, but saving and exiting are not intuitive.

    • Save: hit Ctrl-O (for Output), confirm the filename, and hit the Enter key

    • Exit: hit Ctrl-X

  • Copy / Paste: If you are using Windows and the PuTTY SSH client, you can copy text from the shell by selecting it with your mouse (no need to click anything), and paste stuff at the cursor position with a right-click anywhere in the ssh window.

    In other Terminal programs, copy/paste usually works with Ctrl-Shift-C and Ctrl-Shift-V.
