SSH Console¶ A workstation (Mac, Linux, Window), on the same wifi network as the OVMS module, can use the ssh protocol to connect. In Windows you can use the free PUTTY ssh client. In Linux and OSX ssh is built-in. The syntax is simply. In the AWS EC2 Management Console, click on Instances in the left menu (1) under EC2 Dashboard. Click on the Connect button (2) to open the Connect To Your Instance window.; You will copy and paste information from this window to your Mac Terminal window later. Next, open a Terminal window on your Mac and navigate using the cd (change directory) command to the folder containing the private.
Console Connections¶
OVMS v3 includes a powerful command line console that can be accessed in various ways:
- Using a micro USB cable to a host computer.
If the OVMS is not recognised via USB download the driver from SILABS website). You will also need a suitable terminal emulator. The baud rate is 115200, and you should not enable hardware flow control.
- TELNET (over wifi).
Note that for security reasons, the telnet server component is not enabled in the default production firmware (but may be available in custom builds). If Telnet is available telnet to the IP address of the module (or <vehicleid>.local MDNS address).

- SSH (over wifi).
SSH to the IP address of the module (or <vehicleid>.local MDNS address). Note that when first booted with a network connection, the module takes a minute or so to generate server side keys (which are stored in the config store).
- Web Console SHELL tab.

Use a web browser to connect to the IP address of the module (or <vehicleid>.local MDNS address). A SHELL tab is available for direct command line console access.
- Remote Apps.
The OVMS Android App currently includes a shell screen that can be used to issue command line console commands via the OVMS server v2. This functionality is not currently available in the iPhone/iPad App.
- SMS.
USB Console¶
Our recommendations for the USB console are as follows:
- You can use a Windows, Linux, Mac OSX workstation or an Android device with a USB OTG adapter cable.
- If your operating system does not have the SILABS USB driver, you can download the driver from SILABS website. If you use Linux and your distribution includes the braille display driver “brltty”, you may need to uninstall that, as it claims any CP2102 device to be a braille device. This applies e.g. to openSuSE 15.0.
- Plug in the module to your PC/laptop, using a micro USB cable. Check to ensure a serial port appears (using the SILABS driver). For OSX and Linux this will normally appear as /dev/tty.SLAB_USBtoUART or /dev/ttyUSB0 (or 1/2/… if other serial devices are connected). List your devices using “ls /dev/*USB*”.
- Once the serial port is available you will need a terminal emulator.
- For OSX, the simplest is the built-in SCREEN utility. You run this as
screen-L/dev/tty.SLAB_USBtoUART115200
But note that the device path may be different for you - check with ‘ls /dev/*USB*’. You can use ‘control-a control-y’ or ‘control-a k y’ (three key sequences) to exit the screen. The “-L” option tells screen to capture a log of your session into the file “screenlog.<n>”. - For Linux, the SCREEN utility is also simple to get. If it is not included with your distribution, you can simply yum install screen, or apt-get install screen (depending on your distribution). From there, the command is the same as for OSX. Alternatively, you can use minicom (which is included with many linux distributions).
- For Windows, a simple approach is to download the free PUTTY terminal emulator. This supports both direct ASYNC (over USB) connections, as well as SSH (network). You can download putty using this link.
- For Android, there are multiple USB serial Apps in the Play store. A good recommendation is Serial USB Terminal by Kai Morich.
- Once you have established the connection, press ENTER to see the “OVMS>” prompt.
SSH Console¶
A workstation (Mac, Linux, Window), on the same wifi network as the OVMS module, can use the ssh protocol to connect. In Windows you can use the free PUTTY ssh client. In Linux and OSX ssh is built-in.
The syntax is simply:
Where ‘user’ is the username (normally ‘ovms’) and ‘ip’ is the IP address of the OVMS v3 module. In environments supporting mDNS networking, you should also be able to connect using the mDNS name <vehicleid>.local. The password you enter is the module password.
If you use ssh public/private key pairs, you can store your public key on the OVMS v3 module, to take advantage of passwordless login.
OVMS#configsetssh.keys<user><public-key>
In this case, ‘user’ is the username you use to ssh, and the public key is your RSA public key (the long base64 blob of text you find in id-rsa.pub between ‘ssh-rsa’ and your username/comment).

You can also use SCP to copy files to and from the OVMS v3 VFS.

has been disabled by default andneeds to be enabled manually, either on the command line:…or by adding a host entry to your

file:Console Basics¶
Free Ssh Tools For Mac
Let’s use SSH to demonstrate this:
When first connecting using USB, the console will be in non-secure mode (as indicated by the “OVMS>” prompt). Here, only a limited number of commands are available (such as viewing network status, modem status, or system time). To get to secure mode, enter the command ‘enable’, and provide the module password. The prompt will then change to “OVMS#”:
Ssh Console For Mac Windows 10
You can enter the ‘disable’ command to get out of secure mode, and ‘exit’ to exit the console completely.
When connecting via a pre-authenticated protocol such as SSH, you will be in secure mode automatically.
At any time, you can use “?” to show the available commands. For example:
You can also use “?” as part of a command to expand on the available options within that command root:

The TAB key can also be used to expand on commands or parameter options:
