In a remote shell, how can I find the domain name of the computer from which I logged into the remote machine?
Example: My local machine is
mi.pona.com. On this machine I run
to login into the remote machine
sina.pona.com. In the shell which opens (running on the remote machine) I want to find out from which computer I logged in, so I want to get the result "mi.pona.com". Is there a command for this?
