Disclaimer: The following page is for my use, and the use of my students at the University of Delaware. It is not an authoritative reference about cygwin. If you find it useful, wonderful. But don't rely on it or consider it a definitive reference.
A Unix emulator for Windows. It makes your PC running Windows "act like" it is running Unix. It is open source, and it is freely downloadable.
If you want to be able to do all the things you do on "strauss.udel.edu" without actually being logged into strauss, such as editing, compiling, running C and C++ programs, etc. Cygwin might be for you. It can also help you connect to strauss "as if" you were on a Sun Ray (X Terminal.)
Go to www.cygwin.com, click on "install cygwin now", and take all the defaults. There are only two places you need to do anything special:
If you are enrolled in CISC105, CISC181 or CISC220, the most useful starting set of packages is:
You don't have to install all the packages the first time around. To install or update packages, you just re-run the installer and make different selections.
You may also want to come back later and get the entire X11 tree, but don't do that the first time around; it takes a long time. Once you do that, you can run Cygwin-X, and work just as you do on the Sun Rays (using the mouse in emacs, etc., running Firefox directly from strauss so that you can upload from strauss directly into WebCT, and so forth.)
If you are running in an xterm (i.e. you installed Cygwin-X), use:
ssh -X email@example.com
OR, if that causes some programs to crash, use
ssh -Y firstname.lastname@example.org
To copy from PC to your home directory strauss, use this command (don't forget the colon on the end; otherwise you end up with a file called "email@example.com" on your PC
scp localfile.txt firstname.lastname@example.org:
To copy from PC to another directory, say cisc105/lab03, use this command:
scp localfile.txt email@example.com:cisc105/lab03
This would copy the file AND rename it to foobarfum.txt at the same time:
scp localfile.txt firstname.lastname@example.org:cisc105/lab03/foobarfum.txt
To copy FROM strauss to your local directory, reverse the order of the arguments:
scp email@example.com:cisc105/lab03/foobarfum.txt localfile.txt
To copy a file into the current directory and keep the same name, use a dot as the target (signifying current directory on the local side):
scp firstname.lastname@example.org:cisc105/lab03/foobarfum.txt .
Here is the symptom:
emacs: Terminal type cygwin is not defined.
If that is not the actual type of terminal you have,
use the Bourne shell command `TERM=... export TERM' (C-shell:
`setenv TERM ...') to specify the correct type. It may be necessary
to do `unset TERMINFO' (C-shell: `unsetenv TERMINFO') as well.
Here is the solution:
infocmp -I -1 cygwin > cygwin.src
scp cygwin.src email@example.com:
tic -v cygwin.src
setenv TERMINFO ~/.terminfo
Steps 1-5 need to be done only once. Step 6 will have to be done everytime you log in, or else put it at the end of your .localenv file.
Symptom:You select Cygwin-X programs from the start menu (e.g. xterm) but nothing happens.
Solution:The X server must be running on your machine before X windows programs will run.
Look in the directory where you installed cygwin (typically
c:\cygwin). Under that directory, look in
/usr/X11R6/bin Sort that directory by file type. You should find a
file called startxwin.bat. Make a shortcut to that file, and put it
on your desktop. Always double click on that file once to start up the "X
Server" before you running any X programs. You should see an X in the
system tray when the X server is running.
Regarding the mouse functionality, there is an additional step you have to do: you have to install the X11 package. To install it, go back to the cygwin installer (the same one you used to install cygwin in the first place), and look through the list of packages until you find X11, and select that you want to install that.
After you install it, you need to go into the directory C:\cygwin\usr\X11R6\bin\ and find a file called startxwin.bat. Make a shortcut to this file and put it on your desktop. Double click that file to start up X11. That should bring up a terminal window; in _that_ terminal window, you should find that if you start emacs, it will work with the mouse just like it does with the SunRays.
