Hi Roger,
Thanks for nice information about remote operation of Linrad.
Maybe I will try it even if I don't like to have a Windows
machine at my remote site. Need reliable operation it's 6
hours trip to restore anything.
I have been using TeamSpeak as audio system and it have been
very nice during the 1.5 year I have been running remote operation.
For more information about my setup see http://sm7lcb.shacknet.nu
I'm running remote on 23/3cm over the internet.

Subject: [linrad] Linrad for Windows
Hello, All,
Those of you with a long memory will recall that several years ago [late
2002 or early 2003] I wanted to use Linrad [Linux version, of course]
remotely but was stymied by its use of svgalib for graphics. Svgalib is
a
local graphics solution, and so that meant that while one could run
Linrad
remotely, one couldn't see the screen at the remote location. A network
workaround was found and made a part of Linrad by Leif, but it was less
than ideal to use in practice. This was definitely NOT Leif's fault, but
just a consequence of the environment surrounding Linrad in Linux. The
problem was basically that if anything failed at the remote end or in the
link, since you couldn't see the remote Linrad screen on your monitor,
you
had to know the exact sequence of keystrokes that you needed to input to
blindly re-establish the Linrad network link and get Linrad running in
whatever mode you chose after restarting Linrad remotely with RealVNC.
And not all of the functions were available remotely. So it was usable,
but not an ideal solution when the remote site was several miles away.
There is nothing like driving 4 miles [times two] to do something that
just takes a few seconds to do when one can see the screen ;)
A moment's thought would indicate that the Windows version of Linrad,
which does not use svgalib, should work remotely with no problem as long
as the link has enough bandwidth, and this is in fact the case. I played
yesterday with running Linrad for Windows remotely over a 4 mile Wi-Fi
link and it worked fine. RealVNC did a good job of running Linrad for
Windows remotely, and I used TeamSpeak to send the audio across the link.
I let things run for several hours and there were no hangups or problems.
Even resizing Linrad screen objects remotely was no problem. There was
no
indication of any more audio latency over the wireless link with
TeamSpeak
than I experienced on the wired network at home, even though I also had
two video channels running across the link at the same time [constant
ipcamera monitoring for security].
So if you want to run Linrad remotely, Linrad for Windows makes it easy!
I also tried Speak Freely for the remote audio channel over the network
at
home, and it worked OK. But I didn't use it over the 4 mile link, and so
I can't comment on that. There may be better network audio solutions
than
the ones I tried, but TeamSpeak worked fine for me, and both TeamSpeak
and
Speak Freely were simple to install and get running.
The link is an 802.11b link using a Senao wireless bridge at each end.
It
has been running for about 14 months; before that I used some D-Link
hardware that was TERRIBLE and gave lousy link performance.
