Using Putty and Exceed

[Matt]

Hey guys. I'm having some trouble accessing the Linux servers at my
University from my home PC which runs Windows XP.

Basically we have been told to use both Putty and Exceed (a link for
Putty and a Cd containing Exceed was given to me by my Univeristies IT
Helpdesk) on our home computers to access the Linux servers which we
use in our Computing Lab. Since these labs only run for a few hours a
week, I would like to put some more time in myself at home.

I had no problems with the installation of either program. What is
more, Putty has no problems with logging onto the server once I enable
X11 Forwarding. The problem is that when I run Exceed, nothing
happens! All I get is a small toolbar at the top of the screen. There
is no other activity, and certainty no Linux window popping up as
expected.

Every now and again, I get an error message in the Putty log file
which states:

"software caused connection abort"

This doesn't appear all the time, just usually when I've run the
programs for the first time since my last reboot.

Does anyone have any idea what I might be doing wrong?

If anyone wants any further information then don't hesistate to ask.

Kind Regards,

Matt

You could always run a LiveCD, no need to install anything on your computer,
but you get both X11 and ssh.

As I'm not a microsoft user and never used Exceed, not sure how it's supposed
to look, but you need to run the application on the Linux server and then the
X-Forward will see to that Exceed will display the application on your computer

When you logged in with putty, it will most likely look something like this:

Password:
Last login: Wed Feb 21 18:10:29 2007 from 192.168.0.1
username $

Say you want to run mathlab, then

username $ mathlab &

Using an '&' after the command, you tell that you want to run the program in
the background, which gives you the prompt back, otherwise you need to make a
connection per application you want to run on the remote machine.

If you don't have Exceed installed (or any other X11 environment), then you
can't run applications on the remote machine, as it's not possible to display
it on your machine.

If you type a program name in Putty, it will run on the XServer. Try
typing in "xterm &" or "xeyes &" or "icewm &". Okay, icewm may not be
installed, be "twm" should be. If they recommended Exceed, I'd assume
that means you have permission to run the programs. If "xterm"
doesn't work, report back the error you get in Putty.

I am not sure how this works when running over Putty, but if you were
just doing access via telnet here are a few more things that need to
be setup.
1) your xserver (on your PC -- here I assume Exceed) must be started
and ready to process requests. Check with your IT folks to see how
that is done.
2) Your xserver (Exceed) must have permissions set to allow other
hosts to access him. Depending on your level of paranoia you can just
allow access to all hosts. using a Linux distro (not Exceed) you would
say xhosts + I think.
3) Your DISPLAY variable on the lab linux box must be set to point to
your PC.
If you had just telneted in, and gotten the bash prompt, you could
just say, export DISPLAY=my.ip.add.ress
Now when you run xterm & or xeyes & etc. the code will run on the
Linux lab machine, and send its output to the destination specified by
DISPLAY.

Again not sure how the issue of Putty affects this. I expect not much.

The above aside I second the motion of using a Linux live distro on
your home PC. You can use ssh, instead of putty, and you will be using
proper X instead of eXceed. If you need to save files etc to your
local disk, (or a USB stick) that can be done even from a LiveCD.

Good luck.

Make sure your putty is setup for X11 forwarding also. (Connections,
ssh, tunnels)

With Exceed running, ssh to the host using putty. type "xterm". (without
the quotes.) An xterm should popup in exceed.
