Thank you, this work around works, but i would really like to turn off ssh on my public ip address, but i know the tailscale  approach is not usual (yet).

hi,

Thanks for thenprompt response and sorry for my delay.I tried to see how I could open up Tailscale to you but it requires that you create a Tailscale account and install it on your box  to do it, so I will just use a private key file, which I know will work. If you do want to investigate i am happy to give you access to my ubuntu box via Tailscale to try it out but it’s not a requirement for me.

Gruss

Graham
