How to send messages between computers?

[goude]

By the way, does anyone know how to send messages between computers?

I saw a guy doing it, he can type something and a window will come out on my computer with the text he wrote on his computer.

How does he do that? Can someone please tell me, if you know?

Thank you

We talking in linux or in Windows? In windows I know there is a service where you can type something to appear on another PC in a message box. If both PC's have that service enabled (which I think it's disabled by default now).

Linux Suse 10.1

He is typing something on a terminal and it appers on another machine. Do you know how to do that?

Have a look at the man page for wall
man wall

Thank you for your reply MIkeTbob,

wall command, works , but how can I send a message to a particular computer?

It doesn't say anything on man wall page about it.

Try looking at the man page for write
man write
*note* you may have to enable it, to work correctly.

yes the write command is locked.

I read the man write page and the only thing that mentions about permissions is the mesg(1) [ what's (1)? ]. But this command is only from preventing others sending messages to my machine.

Also can somebody, please tell me what is ttyname?

Thank youuu all!!!
