Question related to wall,write, and talk
 

Friends,
I tried the above-said commands, but they are not working when I do the
following:

[root@station1~]#wall <message>

This will broadcast message only to the terminals in my localhost
but not to other users in the network. Similarly, if I type the
write command "write root tty3" it works but when i type write root@station2 tty1 or root@10.0.0.2 tty1 it wont work. Please let me know where I am going wrong...

I don't think that write or wall are designed to work with remote machines (at least there's nothing in the man pages indicating that they are and I've never seen them used in that capacity). The talk command will work with remote machines, but the ntalkd on the remote system must be configured to accept connections from the net, and ADAICT most aren't. I don't have ntalkd installed on any of my machines at the moment, but a reading of the man page should say something about how to configure it.

Thank u ....btmiller.
