====== System Tips for CS Instructors ======


===== Creating Dropboxes =====

Before your students can use the ''submit###'' script with your course the following prerequisites must be met:

  -  A course account must exist.
  -  You need access to the course account.  
  -  Your students each need an account on our system.
  -  A link must exist or be made for your course number so that ''submit###'' exists.

If any of the above items need to be set up please let me know well in advance of your first lab!

To create the dropboxes:

=== -. Become the course user ===

  you@yourmachine:~$ ssh cs555@vnc

=== -. Deal with any existing dropboxes ===

From the home of the course user look for any existing directories called "dropbox", "Old" or "old".

If a dropbox directory exists from a previous semester and a directory called "Old" or "old" exists,  rename and move the dropbox into the this directory.((If **both** "Old" and "old" exist, use "Old".  It's my call and I'm going to make it.))  Please rename it to dropbox-YYYY-[spring|fall] 

  cs555@vnc:~/dropbox$ mv ~/dropbox ~/Old/dropbox-2007-fall
  
Otherwise if a dropbox directory exists from a previous semester and a directory called "Old" or "old" does not exist, please create the directory ~/Old and then move and rename the dropbox as above.

  cs555@vnc:~/dropbox$ mkdir ~/Old
  cs555@vnc:~/dropbox$ mv ~/dropbox ~/Old/dropbox-2007-fall


=== -. Create and populate the new dropbox ===

Make a new dropbox with modification bits of 750  

  cs555@vnc:~/dropbox$ mkdir -m 750 ~/dropbox

Decend into the new dropbox cd ~/dropbox. Make a directory with permision set to 730 for each student (mkdir can take all the names in one go) 

  cs555@vnc:~/dropbox$ cd ~/dropbox
  cs555@vnc:~/dropbox$ mkdir -m 733 frbaggin luskywal isnewton ajayer jostewar mifoucau stcolber jaderrid




=== -. Confirm all is good ===
Please take a moment to ensure group and permisions are set correctly,  your dropbox directory should look something like this:

    cs555@vnc:~/dropbox$ ls -la    
    total 8
    drwxr-xr-x  15 cs555    asprey2      512 Jan 29 09:20 .
    drwxr-x--x  15 cs555    asprey2     1024 Jan 29 09:16 ..
    drwx-wx-wx   2 cs555    asprey2      512 Jan 29 09:20 ajayer
    drwx-wx-wx   2 cs555    asprey2      512 Jan 29 09:19 frbaggin
    drwx-wx-wx   2 cs555    asprey2      512 Jan 29 09:19 isnewton
    drwx-wx-wx   2 cs555    asprey2      512 Jan 29 09:20 jaderrid
    drwx-wx-wx   2 cs555    asprey2      512 Jan 29 09:20 jostewar
    drwx-wx-wx   2 cs555    asprey2      512 Jan 29 09:19 luskywal
    drwx-wx-wx   2 cs555    asprey2      512 Jan 29 09:20 mifoucau
    drwx-wx-wx   2 cs555    asprey2      512 Jan 29 09:20 stcolber
    cs555@vnc:~/dropbox$


Check that the permisions on the directory itself and on the student dropboxes match these.
If they do not, use chmod to correct them:

   chmod 755 ~/dropbox
   chmod 733 ~/dropbox/*
   

Finaly, with the exception of cs101, check that the group is set to asprey2((for cs101 the group is cslab)), if not fix that with chgrp:

  chgrp -R asprey2 ~/dropbox
