HOWTO use cunix and its software

It is a tutorial for my friends, who have be asking me for a while.

As many of you know, that you can access the Linux server if you are a student in CU. And there are a few softwares you can access via that.

1. download and install putty (assume you are using windows, otherwise you probably knew this already), which is a ssh client.
2. install Xming, which is X-server for putty, or you may wanna call it graphic support.
3. open putty, and click session tab on the right, enter the server's name: cunix.columbia.edu. use SSH, and then on your left again: connection->SSH->X11 click enable X11 forwarding.
4. go back to session tab, save your session setting and load. Now you are on your way to use cunix~
5. you can also use sftp to manipulate the files on the server. Notice everything we put in the public_html is accessible for anyone, unless you change the permission setting.
(This is also the place you can hold and publish your own website, though the storage is tiny....)
6a. okey, okey, now software. but all you need to do is just type "matlab" or "mathematica" after the cursor. wait for a few seconds, and your familiar software interface will pop out.
6b. i f you are fine with terminal and dont need the graphic interface of those software, just don't check " enable X11 forwarding" in step 3.

Have fun with it, my friends~
