The Question is: I want to send a message in a text file that appears in the screen of another terminal in other network node. I was trying it with the copy command, the text file and the terminal's id, it works, like this: $ copy/log file.txt TNA8090: but the problem is when i want to send the message to a terminal in another node, could you tell me if there is some format command that can let me do this? Thanks. The Answer is :
When posing questions, please always indicate the general problem that
is to be solved, in addition to the specific question(s) you might have.
This background greatly assists the OpenVMS Wizard is providing you with
an appropriate answer for your question -- various alternatives may well
be available.
The requested task requires a server, a package or process or application
on the remote end that assists in servicing the request to display the
information on the remote terminal. Further, in OpenVMS, the basic task
involved here itself requires enhanced privileges, when there is a user
logged in on the target terminal.
You could potentially use the DECnet File Access Listener (FAL) as the
remote server:
$ COPY/LOG file.txt node::TXA4:
FAL is how DECnet systems can perform remote file operations, including
record-level file sharing and device-level access.
The TNA8090: device is a Telnet device, which indicates the network is
at least partially based on IP networking. IP does not include a direct
analog to FAL, the closest equivilent to FAL is the FTP server.
If the target system is OpenVMS, tools such as DECnet task-to-task
(possible from DCL) as well as tools such as rexec can often be of
assistance with performing specific tasks on remote nodes. Using DECnet
task-to-task, a client and a server -- possibly written entirely in DCL
-- are in communication, and can perform most any task that a local
application or DCL command procedure can itself perform.
There are various books and manuals available on this topic, and there
is an example of DCL task-to-task on the OpenVMS Freeware, specifically
see the [SRH_EXAMPLES]XQTYPE.COM procedure.
There are also IRC, SEND amd similar tools available for OpenVMS from
various sources, as well as for other platforms obviously.
