Question

I am trying to do ssh connection from Ubuntu machine to a pi. I am getting the following messages
Command:
ssh -vv PI_ipaddress -l pi

Note:
If I use ssh in my pi, it works. But from other systems, I am unable to access.
The password I entered is correct. No issues there.
I reinstalled ssh in pi, still it does not work.
I tried disabling GSSAPI from a windows machine(just cross-checking).Still no connection
I googled the issue and I could not arrive at a solution
Ping works from
any system to the pi.
Any help is appreciated.

Answer 1

So the solution is sort of intuitive. The keyboard layout between the Pi and ubuntu system were not the same and hence gave out error while giving password which was unknown to the user.
