X server insecure (must use xauth-style authorization)
WJR - Just curious, what's the connection to Tcl/Tk? Are there specific issues with Tk on 3rd party X servers?
Tk's send command relies on xauth to provide basic remote access security -- it will throw the "X server insecure" error if it's not properly set up and it receives an incoming send. Maybe 3rd party X servers just don't come configured properly for remote access. See [L1 ] and [L2 ]
What happens when you bring up your X server?
I get a little window in the center of the screen asking me to log into the host computer.
I get an xterm on my favorite host, or I have to launch clients from menus or dialogs.
Here's instructions from Hummingbird about how to set up xauth between Exceed and a Unix machine: http://www.hummingbird.com/support/nc/exceed/xauth.html?searchType=Basic&searchText=xauth&rank=1 [LV} Alas, that URL no longer appears to be valid - at least, when I follow it, I get what appears to be the front page for hummingbird AND when I search the site for xauth, the search reports no hits found.
Note that one may encounter a variety of problems when trying to run Tk applications on a Unix platform and displaying back to the Exceed X server (at least through version 10.0.0.12) .
