Using CYGWIN to get the mathlets
This document exists primarily to give an option to
who seek to run athena courseware, such as the mathlets
from their MSWindows desktops.
The overall strategy is to run them on athena and use cygwin on
MSWindows as the display.
I used to do this quite a lot at my former job, but I don't do it
here, so the instructions I am giving are from memory. If you find
that they work well enough for you, then
If these instructions are incomplete enough that something goes wrong,
but you want to try and work it out, then
email me and we will
try to get to the root of the problem, fix it, and modify this page
for everyone to benefit. Otherwise, don't bother me with
it just doesn't work because that isn't useful.
Another guide to this approach, using a different set
of programs is given
here. In principle, it does the same sort of thing. I haven't
tried this way. Maybe someone reading this could and give me feedback.
Go to the cygwin site and click on
the install or update now! link. You can also just try to use
this link here.
Say yes to the defaults.
At some point you will be given a list of sites to download from.
Pick one that looks close somehow.
Then, after some time, it will give you a list of optional packages
to install. There are three which you really should get (and their
dependencies will force the rest).
fvwm2: under XFree86
OpenSSH: under either Security or Network, I don't recall
vim: under Editors
OpenSSH will let you get a remote shell on an athena machine.
fvwm2 won't really be used, it is just there to pull in all the
XFree86 dependencies you need. vim will likely only be used
if there is some problem which needs fixing later.
Say yes to everything else after this and accept all defaults.
using cygwin for the first time
Depending on how your MSWindows is set up, when you first run cygwin
you will get a message at startup asking you to issue commands like:
mkpasswd blah blah blah
mkgroup blah blah blah
Type in each line (they take a few seconds to run sometimes).
If there is any place where things go wrong this is it.
One you are done with this, then kill the cygwin window.
If no such messages come up and you get a bash prompt,
then you're good to go.
using cygwin the next time
Assuming all went well the first time, the next time you start
up cygwin you will get a window which has just a prompt which looks
or something like that. The next step is to start up an X server.
There are a few ways to do this, but the way that is easiest, if
I recall correctly is,
If all goes well, then this command will cause two xterm
windows to pop up and a little X to appear in that
MSWindows system tray (right-clicking
on the little icon is the only way to shut X down).
This means the X server has started.
using cygwin as a remote display
If you have gotten this far, everything should just work.
Start cygwin up, then start the X server up, then go to
one of the newly popped up xterms (this won't work in the
original cygwin window) and type something like
yourname@yourmachine$ ssh -C -X email@example.com
If it asks you something about never having connected to this
host before, just say yes. You will be prompted for your
athena password, and proof, you get an athena prompt. Only
now your X display is routed to your local machine.
athena% attach 18.03
athena% cd /mit/18.03/tools/sunos/
And this should work.
