Well, assuming you don't want to create a *SHELL* on another node's
monitor, it's pretty easy. From Aegis, getting the display manager to
create an interactive shell is difficult or impossible (at least, I never
figured it out :-)
But. back to the question at hand. One-line messages can be sent via
send_alarm, assuming the receiving node is running an alarm server. The
format is
/com/send_alarm "message here" -n //node_name
/com/send_alarm "message here" -u user_name
/com/send_alarm "message here" -alln {all-nodes}
If your message is too long, or if the recipient isn't running an alarm
server, you can still cheat, by creating a remote process on the node (crp)
and then using the create_pad (crpad) command. For instance
crp -on //recipient_node -me
<press the [HOLD] button to lock scrolling>
crpad
Type in your multi-line
message here. Note that the [HOLD] key
prevents it from being acted on yet.
*** EOF *** (press cntl-Z)
<press the [HOLD button lo unlock scrolling>
logout
I always enter it with the scroll-lock held, to prevent the recipient-node
from creating the pad until AFTER I type in the message. Otherwise, the
user on the receiving end may close off the window before you get to type
in it.
You can re-direct input to the CRPAD command, so it should be do-able from
a script as follows
crp -on //node_name -me "/com/sh -c '/com/crpad < mess_file'"
Hope this helps...

I've been writing about this under the topic "Processes in GPR_$borrow mode.". Can anyone from apollo.com listening in send a APR or CRUCR for me on this? I would like root/sys_admin and only these two to have the capability to break into a borrow mode process. Many thanks in advance. fclim --- gbopoly1 % nusvm.bitnet @ cunyvm.cuny.edu computer centre singapore polytechnic dover road singapore 0513.
