Title: Windx connection fails to execute Linux program
Post by: Lawrence_Leavell on August 09, 2018, 06:11:45 PM

Linux system, Windx emulators, 40+ users, SSH or telnet connections.
Attempting to SYS("dv") and the system immediately returns to the "-}" prompt without running the program. Why is this and how to stop this behavior?

dv = Doublevision http://itivity.net/doublevision/

How about sys("dv 2>/some/errorfile")?

I'm amazed DoubleVision is still available.  I'd be more amazed if it could tap into a WindX connection and do anything meaningful with it, unless it's become a graphical tool.  They used to just map character mode devices, depending on the server side to just be sending out ansi or similar terminal escape sequences.  WindX has its own protocol for transmission (just think about those FIN packets mentioned earlier).

What about using web meeting software, like teamviewer or gotomeeting?

Allen,
We use "dv" to manage processes which are running independently on their own "terminals" in the event of a error or some other issue. There is no operator on such terminals.

DoubleVision cannot handle the WindX protocol.  We suggest if you wish to continue to use DoubeVision that you use it on standard text mode terminals that DoubleVision does support otherwise use one of any number of Windows desktop sharing programs or Windows RDP which comes standard with the Professional version of Windows 10.
