I am considering proposing to a local college that they use GRASS to set up
a GIS program.
The idea is to use Linux as an application server with GRASS installed, but
for the students, through Virtual Network Computing (VNC) actually use the
GRASS on Windows 95/98 boxes.
Does anyone have any experience with this; particularly with respect to
demands upon network performance and upon the Linux box, but also with
respect to any other topics as well.
I would appreciate any advice, warnings, or comments.
You can set GRASS up on a linux server and use a X-terminal emulation
package such as Xvision or Hummingbird to link the linux and Windows 98
machines. Ideally, your linux box should be as close as possible to
your Win boxes. We have a lab set up like this and everything is on
the same hub on the same side of a bridge. Performance is great.
Any other questions on our specifics, email me.

Price is an object. Is there a GNU X Server or something like that?

I used Linux server with GRASS.
This server was connected to Windows (95/98)
network. MIX server was used as a X server
under Windows. Yhis is a free X server.
Additionally Samba server was insaled.
So each user could use Microsoft software
with GRASS statistics.
I had some problems with screen refreshing
but I have this problem with GRASS monitor
on each computer (server and X terminal).

Yea, and TNTMips is great. If only I had $10,000 to get the full
version (instead of the free TNTLite). By the way, isn't that MI/X for
the name of the X server?

The two I know of are free. Microimages (www.microimages.com I think) has
one that works very well, and very fast, but there is the isssue of fonts
(which they tell you how to solve in the documentation). I haven't tried
GRASS on it yet, but if I do I'll try to let you know how it looks.
Microimages now charges $25 for its version. (Apparently a very recent
development)
What is the other free X server you know of? (I need to run it on a Windows
box.)

I apologize for being stupid, it's the heat and a hangover, but I can't
remember the other...I could find it again. Check the earlier responses
to your question...someone mentioned it (I erased them it seems). I just
sent you a gif, but I forgot to mention I could send you the Microimages
server as a zip file, it is self-contained in a single directory. I
could also put it on my ftp site if you don't want big attachments. I
could also send you the qvt stuff if you can't get it. It has an ftp
client and a web server and ftp server for Win32 also. Very nice
programs to have around.
Xserver caveat:
You would have to start it with the tntstart program and not the xserver
program to get the window manager (TWM) which gives you placement
control over the startup windows, but other than that it is pretty
simple.
I had trouble with overlapping dialogue windows blacking out regions of the
image in the monitor, but no font errors.
I also experienced this problem with the MicroImage demo version
Is there anything that can be done about this.
Alternatively, where can I find information about X servers generally.

Spend the money on Hummingbird's Exceed X server - it is a very robust
product, and probably the best of the bunch. We've used it for about
five years now. As a bonus, it includes a very nice ftp client.

Try Starnet's Xwin32 before shelling out for eXceed. When I compared them a
couple of years ago, I found we had stuff that ran on Xwin but not eXceed. Xwin
is fast, cheap (especially for education) and easy to use. It's 'Pseudocolor
support in truecolor mode' option lets you run 8-bit GRASS monitors on 16- or
24-bit PC screens. We've been using Xwin and Xwin32 for about 4 years on about
20 different PCs (Windows 3.x 95, 98 and NT) running applications on SGI, Sun
and Linux with no problems.
If you want the ftp client (and some other goodies) buy the Hummingbird stuff.
If all you want is a good X-server, then XWin is the business. Starnet's WWW
site is www.starnet.com (I think) where they have a demo version.

PS - Malcolm, I have a sense of 'deja-vue' about this email - have we had this
conversation before?
I am considering proposing to a local college that they use GRASS to set up
a GIS program.
I tried this also but is it ain't MS they have a hard time getting
interested.
The idea is to use Linux as an application server with GRASS installed, but
for the students, through Virtual Network Computing (VNC) actually use the
GRASS on Windows 95/98 boxes.
Now with GRASS but I use it to connect to the Win95 box I use at work to
run applications on other networked boxes over a 33.6kbps modem (but the
phomne lines usually only get me a 24.4kbps connection) and am not unhappy
with the response. Given a choice of $$$ and slower performance I'd lean
toward the slow performance. Besides we should click then reflect on the
actions instead of the manic click-a-thons I see from most MS users.
I also have vncserver running on my Linux box at home and it dialds in
every hour. Since I have applications on it that I can't get on the Win
platform I can do some work that would normally require me to go home or
work at night. Again I'm not un-happy with the preformance over the phome
lines.

I, too, have been very pleased with X-Win32. It is much better at
giving
proper colors than other X programs I have used with PC's. They have
a very generous site license program so that when a Physics lab on our
campus bought the site license, the program was licensed for the entire
campus network.
