Seaside Hosting question

Hello,

I just got this message from tech support at Webfaction. We are trying to get Seaside available as an option.

But I am woefully inadequate to answer his questions well.

Below is the email he sent me.

Any help and answers greatly appreciated. I would love to enable them to get Seaside hosting going.

Thanks.

Jimmie

I start my images like this:

    squeak \
        -mmap 256m \
        -vm-sound-null \
        -vm-display-null \
        "$IMAGE" \
        -- PORT "$PORT"

I am using VNC (the Squeak implementation) to connect to the image.

Do you still supply the port as above?
-- PORT 8888

Webfaction has several plans at various mb of RAM allowed.
Does passing -mmap 40mb constrain the image to 40mb?
Would it crash if it attempted to go higher?

I'm pretty sure they don't have or allow VNC. Everything would have to
be done via web browser or command line (ssh).

Are there any problems running a development style image, squeak-dev
with Seaside and running it headless? Other than extra memory and space
requirements.

Eventually I would love to have a kernel image with current Seaside/Pier
loaded, and do OmniBrowser and Monticello via web browser.

Thanks. And thanks to Isaiah also for his reply.

I think the VNC Lukas is talking about is something Webfaction will have no
problem with. It's not VNC as you first think of it. It's just a function of
Seaside that allows a System Browser to open in a Web Browser. This means
that once your image is uploaded you can access the image in the same way as
on your desktop -- except in a browser.

Mm, no - he's talking about the RFBServer implementation from Ian.  We
use that extensively too.  It is indeed VNC (the Chicken of the VNC
client works well), but it requires no special server support (beyond
any firewalls letting port 5900 through).

Yikes, I'm wrong on this one. Thanks for pointing that out. I've found some
great stuff on it:

Is the port configurable?

What kind of impact does it have on server resources? CPU usage?
I'm not sure that a hosting provider will allow such if the resource use
is above the plans limits.

I presume one can write a method which can be called via a web browser
to start or stop service from the RFBServer.

Can one operate something like this:

Have the RFBServer running but no client connected.
Such would hopefully have little resource usage. Just a guess?
Then if you encounter a debug situation, you can possibly have a client
connect, debug, disconnect. ?

Thanks for any additional information.

Correct.

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.
