how to make icfb resumable after a unexpected terminal disco

[walala]

Dear all,

I need your help.

I am a student who do research using Exceed to access Sun workstation in our
school to use Cadence EDA software. Due to Microsoft's security hole, they
frequently roll-out new security updates.

The system manager at our school has a software to automatically download
and push those new updates to our computer. The problem is: it auto-restarts
my PC... while I am running Cadence software remotely using Exceed...

This month I have a bunch jobs killed in this way by the new security
updates automatical restart! One of them I had runned for 6 days and it was
killed. I am very angry about this!

I know "nohup" can make sure that the process is running even if logout. But
how about Cadence software which has graphical output.

Imagine I use "nohup icfb", where "icfb" is the Cadence EDA software that I
am using, it has a graphical output. Then my computer was restarted, and
then I relogin, restart my Exceed, the "icfb" process is still there, but
with no owner, it is dead process, and its graphical interface is gone...

By the way, "icfb" is strange that it cannot be used "nohup icfb &"...it
will hang after several seconds....

What can I do now? Please help me!

hi

We have started to use Xvnc which allows you to re-connect to your
original xwindows session after disconnection.

Citrix's ICA, and also Sun's SunRay product also handles disconnects nicely. If
the XServer goes away, most tools will die, because the file descriptor that
that they were writing goes away.

For these frame buffer type tools (like VNC, Citrix and SunRay), the X server stays connected,
but there is a layer between the X server and what you see, and that is what handles the
disconnects (a rather simplistic description). These then give the facility to take your display
with you (if you like).
