Have set up on my P2P network, which is predominatelty Windows, four more
computers.

RS6000 with AIX 4.3.3.11
RS6000 with AIX 5.2.10
Sun Sparc with Solaris 9
Sun X86 with Solaris 8

Each Unix computer has its own browser and can connect to the internet and
also receive and send emails.
Each Unix computer can ping one another okay and the router.
Each Unix computer can do print outs on the one network printer.
For ease of use, no Unix computer needs a password.
There is only one user called root on each computer.

I am now at the stage of my learning, trying to communicate between the four
Unix computers.

With all the four Unix computers turned on and the P2P Workgroup TCP/IP
network going
Entering #who in each computer does not show its other three Unix mates on
the network.
Entering #write root <host name > or
Entering #write root <IP Address >  does not work either
Have tried mail , Mail and sendmail with every address I can think of, but
all this does is lock up the computers, forcing me to restart them.

Sorry guys, I kow this is something pretty basic, but I need a helping hand
to get over a  simple step.
Of the dozens of articles I have read, I just cannot seem to connect with
anything to see what I am missing.

Regards
Basil

Are you saying you are working on a root-account without
a password...you are either pretty brave, or you're
tickleing the devil at his tail.

The "who" command only shows users logged onto the local machine.
It's not designed to show users logged on elsewhere.

man write ...
SYNOPSIS
write user [ttyname]

Are you sure you use the "write" command in the correct way?

The mail system needs to be configured correctly before
it will work. ... Nevertheless, a restart shouldn't be
required. Why don't you log on with a second terminal/session
and see whats going on?

Basil, no offence meant, but you seem to lack some basic
knowledge about unix systems in general.
