How to display xterm windows on Openvms

[Srikanth Arunachalam]

Hi,

We are to setup new OpenVMS kit for itanium (v8.1-2). I have set the following
SET DISPLAY/CREATE/TRANSPORT=TCPIP/NODE=
while I execute the below command the display doesnt comeup.

Please advice.
RUN SYS$SYSTEM:DECW$CLOCK


thanks,
Srikanth

As with any x-window environment you have to open up your security on your display on "node1". Your "node1" must also be able to resolve via either hosts.local or DNS lookup.

Assuming TCPIP:
nslookup node1

tcpip show host node1

In Linux, the "xhost" command is used to allow a remote node access. There are menu choices in the Windows add on packages to configure a server trusted to open X windows sessions. You may also want to try adding /screen=0 to the SET DISPLAY command.

An excellent reference is: Linux & OpenVMS Interoperability: Tricks for Old Dogs, New Dogs, and Hot Dogs with Open Systems

What is "node1"?

What _does_ happen when you RUN ...?

In SYS$MANAGER:DECW$PRIVATE_SERVER_SETUP.COM,
does "decw$server_transports" include
"TCPIP"?

Hi,

Thanks everybody. Due to security reason, we cannot set the environment for xwindows. I will revoke the idea suggested by Oracle installation and will look for some other alternative.

Thanks,

I assume login to the VMS system from a terminal window on node1, and the security setup does not allow insecure X11 connections to node1.

One possibility is to use SSH with X11 port forwarding: then You have a secure X11 connection.

Another option is xauth/kerberos authentication instead xhost. I have no experience, but I think actual Decwindows/Motif supports that.

Your network security requirements may allow for a secure tunnel. You can use a VPN client/server to tunnel secure traffic. I've used X over a Cisco VPN session to send performance graphics from an Alphaserver in one state to a PC in another state.

Hi Srikanth,

what is your terminal software? Is it a Putty or reflection X? You may have to use something like eXcursion if you are using a Putty or Pathworks.

The eXcursion X server lets you run X applications from any supported operating system on your PC

Agin, if you are using a SSH connection, you should have the correct port forwarding. Otherwise, it wont work.
