This is a simple setup guide to enabling Two Factor Authentication (2FA) on Linux SSH login. I this article I wont go deep into setup and issues that I have faced when implementing this. First thing is first Update your system first. I have used Ubuntu 20.04 and it is always up to date. To enable 2FA you need to install google authenticator modules sudo apt install libpam-google-authenticator Configuration for PAM and SSHD Add the the following line to /etc/pam.d/sshd and After adding this line please restart the sshd services. auth required pam_google_authenticator.so Go to /etc/ssh/sshd_config and check if the following line exist. Default value will be "no" so change it to "yes" to activate. ChallengeResponseAuthentication yes Configuration for Authenticator In the terminal run google authenticator command It will ask few things to acknowledge by user. Details you can see from the below video. Once this part is done you are ready to use the 2FA in ubuntu. T...
Today we planed to conduct as much as possible test runs before sunset so we did three successful missions. For today's test new gadget was introduced to record video from front of the boat. So i modified a key chain camera( which the battery is damaged) and fixed a 3.7V battery to power it and it was gooood. :). I gave a name to this mod as "Go puroa".
Conclusion: There few code fixing to be done while calculating the next way-point. This is not a big issue or effect any mission runs. Problem is it does a 360 degree turn when going to next way-point. which is not a problem but better ways are always there and testing will make perfect each and everyday.
Go puroa
All the three test was good but due to some technical issues an unattended guys the test was bit delayed. The boat traveled around 60 - 70 meters wider way-point locations.
Command center which uploads all mission way-points and manual override if any thing goes wrong (if the boat goes too from reach due to some error).
Few data result of the test . Even though the sea is not calm enough the boat tries its best to with the small waves.
videos will be uploaded soon once all videos are converted to up loadable format to YouTube.
