DecWindows on a iMac

Zeni B. Schleter — Mon, 04 Jun 2007 08:55:57 GMT

Using steps from an article by Stephen Hoffman , I was able to connect Via X-11 window on my iMac to a remote OpenVMS Host. I was able to start the clock, the puzzle, and an editing window. The editing window (EVE) is a great help since it lets my bypass the issue of key definitions.

I could not get the Create/Terminal=DECterm [/DETACH] to work. It would just hang. Show Display gave expected results. Other DECWindow utilities worked as expected. This is not critical ; just curious.

Any ideas why a Decterm Window would not get created? TIA

A guess: DECterm is looking for some X Windows extension not available with Mac OS X, and is then not detecting and reporting the error?

Locally, there are (only) the BIG-REQUESTS, XC-MISC and LBX extensions available.

The other option is security; the xhost stuff.

Another option might have been that the detached process is not getting the connection context back to the Mac OS X box via SSH -- though I'm seeing this same behavior without /DETACH.

I'll head off and look at this; this is odd and interesting.

Got it. An update and a related comment) have been posted to the base Mac OS X article at http://64.223.189.234/node/134 -- short answer is to use ssh -Y from the Mac OS X client, not ssh -X. ssh -X does most of what is needed here, ssh -Y does what is needed for DECterm. Longer answer is over at the cited article, as well as some other trivia I learned chasing this. (Thanks for the error report, too.)
