[comp.windows.x] X-window applications vanish when gateway is rebooted

jmd@ursa.UUCP (Josh Diamond) (09/27/89)

Greetings:

     I have noticed the following behavior on out network of sun,
hp and convex machines.  If a gateway machine between my X server
and the host on which the X-Window appliction is running is rebooted,
then the  X-Window appliction goes away.  I do not see this behavior 
with rlogins.

     Here is a simplified picture of our network:

	[fis-backbone]
	|
	|			[rupert-net]
	|-rupert------------------------------------------
	|                |           |          |
	|	       sun-a       sun-b     convex-a
	|
	|-share
	|
	|			[breezly-net]
	|-breezly-----------------------------------------
	|                |           |          |
	|	       sun-c       sun-d     hp835-a
	|

      So suppose my X-server is runnibg on sun-a (DISPLAY=sun-a:0.0).  I 
start up an xterm running on sun-d, displaying on sun-a:0.0, and an rlogin
from sun-a to sun-d.  Now, if rupert or breezly go down, both the xterm
and the rlogin hang.  When the gateway machine comes back up, however,
the xterm vanishes, while the rlogin returns to normal.

     I have also noted that the xterm usually will disappear if the
ethernet cable is disconnected and then reconnected, while the rlogin
remains.

     Any help on this problem would be most appreciated, as we are
in the process of switching to X-Windows, and this is causing major
problems for us.  We do not want our X-based application running on
our convex to suddenly die just because the gateway was rebooted...

			Thanks in advance...

I will post a summary to the net...
