Uploading files (e.g., Studio Designs) to your web space

Using Windows Explorer from the CS lab machines

1. Log into one of the CS lab machines ("Log on to:" should be set to "CSEPCLAB"), and open Windows Explorer.
   
   
   
2. In the address bar of the Windows Explorer window, type O:\unix\projects\instr\09wi\cse441\students\[username] where [username] is your CS Net ID, and hit Enter.

3. You can now drag files/folders into here to structure your web page as you wish. Make sure you have the index.html file set up to link to all of your relevant contents.

Using SFTP from the CS lab machines

1. Log into one of the CS lab machines ("Log on to:" should be set to "CSEPCLAB"), and open an SFTP connection to attu.cs.washington.edu.

2. Set the destination directory to /projects/instr/09wi/cse441/students/[username] where [username] is your CS Net ID, and hit Enter.

Using SSH from your own computer

1. ssh to attu.cs.washington.edu using your CS Net ID and password.
2. cd to /projects/instr/09wi/cse441/students/[username] where [username] is your CS Net ID.
3. You can now edit files/folders in here to structure your web page as you wish. Make sure you have the index.html file set up to link to all of your relevant contents.

Uploading files to your project group web space

Each project group has been assigned a web directory, similar to the individual personal web directory described above. You can view these directories under the Projects section of the class website. You can access the content of your web directory from one of the CS lab machines (using Windows Explorer or SFTP), or from your own computer (using ssh), as described above. The only difference will be that wherever you had "students/[username]", you would replace it with "projects/[projectname]" where [projectname] is the initial name that was given to your project.

***Make sure to follow the instructions in the section below to ensure your group members can access your files properly!***

Making sure your group members can modify your files

Each project group has been assigned a Unix group (e.g., cse441z), and all members of your project group has been added to be members of this group. You can find out which group you belong to by issuing the command "groups" in your Unix account.

Whenever one of your group member creates a file or a directory in the project web space, you have to ensure that the file/directory has the permission set to "group writable" (and readable of course). You can check what the permission is for a particular file or a directory by issuing the command 'ls -l' in a directory. Here's an example of what that might look like:

The stuff on the left column show the permissions (e.g., "-rw-r--r--"). What you're looking for are the 5th and 6th characters in that string. You want it to say "rw" instead of "r-". If the file or directory you created (which you can verify by looking at the 3rd column and seeing your username there) shows "r-" for the 5th and 6th permission characters, you need to add the group write permission to it by issuing the following command:

Or alternatively, you can recursively set the group write permission on all the files you've created in the directory by issuing:

In order to make sure that future files that you create automatically have the group write permission set, you need to either issue the command "umask 002" each time you log in, or add that command at the end of your .cshrc file in your home directory.

Using Subversion for version control of your project files

Thanks to Jim George, here's a starter for those wishing to use a version control system for their project files:

A bit of background, SVN stands for Subversion and it's one of a few popular Version Control systems. Version Control makes it easy to keep your source code safe and share it among multiple people.

Read up more in the following links if you want more background:

• Wikipedia article on Subversion
• Wikipedia article on revision control
• Subversion homepage
• Subversion book (online documentation)
• TortoiseSVN (Windows graphical Subversion client) homepage
• TortoiseSVN online documentation

First thing to do is through a terminal log onto the attu server using SSH.

From here you can do step at step 2 through 5 of this tutorial, which has you create a repo, edit a few files, make user accounts, etc.

Step 6 will be a little different because we need to use svn+ssh to import the source (assuming it is on your local machine).

So run this command from your computer (requires SVN to be installed):

If this is successful, you will see a bunch of lines starting with Adding <some file> and then at the end "committed revision 1".

From this point you and your team can all access the source by:

And you're set!

Hope this helps somebody =)
