I have recently tested using NetView over a remote link using ssh. Not
by tunnelling X through ssh but by using VNC (Virtual Network Console)
over ssh through to my NetView server. This experiment was for a client
who had an ADSL connection but I actually tested it yesterday over a
dial-up (52Kb) and although performance obviously wasn't brilliant, it
was usable as an occasional thing and it didn't drop out / collapse or
do anything else nasty.
I was using public domain software - VNC server on my AIX NetView
server and VNC Viewer on win2K, plus OpenSSH 3.7.1.0 on my AIX 5.1
NetView Server and PuTTY for ssh on my Windows.
If you need more details, please feel free to contact me directly.
Cheers,
Jane

I never do anything but telnet to other lab boxes, because my job only
requires minimal interaction with the GUI. Usually I am concerned only
with nvevents. And it was not my decision to not support the native
NetView client-server on Linux. Linux poses its own challenges with
regard to GUIs and Window managers and having to support native
client-server would have delayed the Linux implementation of NetView
considerably. That was a strategic decision in marketing and
development. The view there, in marketing and development, is that
you should be looking at the web console to replace multiple X-windows
connections or learn to live with the overhead.
That's all I can tell you.

Subject: Re: [nv-l] Netview clients
Hi James, as i know (reading the manuals) i cannot
reduce the server load using X-Windows because the GUI
would be working on the server consuming CPU and
memory. I use this scenario (Linux connected to my AIX
box using X-Windows) but i want to reduce the server
work using several clients.
As you told me in another e-mail i think i cannot make
improvements on the performance of my server at least
i purchase another AIX or Solaris machine :o(
Some time ago i made a test using X-Windows over SSH
but it didn't work with the Netview GUI, but it works
fine for other applications for example Tivoli Desktop
and xterm, have you tried this configuration?
Thanks for your answer.
Regards
Oscar
