Display X windows

[nipun_2]

Hello all,
We have OpenVMS 7.3-2 (not the NEW Desktop Environment). Now if we generally login to the session we are able to run applications (X windows based...applications).

We currently have the main server housing the system disk and 3 other stations. There are also few accounts. Users often require to login to account 1 and then when they are in the account

often do a (in the terminal window)

$set host 0
username: ACcount2
pwd:XXXXXX

However, when the user now tries to access any of the applications that would basically open up in a new window (example running text editor applications etc. ) we get an error.

I believe the reason for this is because we need to setup the terminal

using

$display

command with some qualifiers but it is not clear what should they be.

Any help in this matter would be great.

Thanks in advance.

To create a remote display, use the SET DISPLAY command, e.g.
SET DISPLAY/NODE=node.here.there/trans=TCPIP,
see HELP SET DISPLAY.
Be sure to setup security to allow the remote client to open windows on your desktop.

Nipun,

In the workstation X-Session may require to set â Session Manager->Option->Securityâ then put "*" in Node, "*" in Username and TCPIP or DECNET what ever you are using.

In the server issue $SHOW DISPLAY, if the node name differs from the one the user has logged in from then set the display with e.g
SET DISP/NODE=nodename /TRANS=TCPIP

Now try your command.

Regards,

Shankar

This DECnet remote login construction is typically an indication of some form of accounting or auditing, or of some form of a site-specific access control issue.

If used for process accounting or auditing, there are (or were) tools around which implement charge-code accounting. Freeware tools such as HGLOGIN and GLOGIN can be solutions here, and commercial packages are (or were) available.

If this was used for access controls, there are mechanisms using access control lists and identifiers which can entirely eliminate the need for the DECnet network session. And that can maintain standard OpenVMS auditing and accountability.

Using ACLs and identifiers will allow the users to log in once, and it will not derail your X Windows DECW$DISPLAY setting, nor will it mask the symbols, logical names or other parts of the original login process context.
