command-line

I read here that this should work, but it doesn't:

//usage: wall [file] root@sys:~> mesg is y root@sys:~> wall "who's out there" wall: can't read who's out there.

If mesg is set to y, what's preventing me from broadcasting a string? Note, I did confirm that the file option works:

root@sys:~> wall test
Broadcast Message from root@sys (/dev/pts/1) at 15:23 ...
Who's out there?

Teach me knowledge please.
