I have a user of name x in tty1 and y in tty2. Now x wants to write some message to y and vice-versa.
Now I typed in tty1 terminal write y tty2
It is showing
write:write:you have write permission turned off
write:y has messages disabled
Same thing is showing when y's sending message to x instead it is 'x' in the last line. What should I do?
