Hello Janko,

The Seaside people do not keep RFB running all the time. They only start
it up as necessary. They have a web interface to start it up. At least
that is my understanding.

I have had the opportunity to start into AIDA/Web yet. I am currently
reading the docs. But maybe something similar can be added to whatever
web based configuration interface is available.

Below is the text of an email conversation I had on the Seaside mailing
list. Message and thread available at:


Hope this helps.

Yes.  The standard range starts at 5900.

Yes, some versions of Seaside include WAVNCController which does
precisely that.

We have it not running, and in fact suspend the UI process, until
there's a problem.  WAVNCController lets us start up the VNC server
and resume the UI process so we can go in and take a look, and then
shut these off after we're done.

Suspending the UI process does help to conserve server resources.
