FAQ

Websubmit
I had a problem with the websubmit today in my Lab section. It would not let me log in to submit today's lab or the homeowork.
If you had an authentication problem (e.g. login screen did not accept username/password), then it is an issue with your university username/id -- and it might get fixed by just closing and restarting the browser.

If the problem was either that you never made it to the authentication screen, or else that you authenticated and then had an error, please let me know more specifically what happened -- maybe by taking a screenshot of it and emailing it to me.

Websubmit
I logged into Websubmit, and tried to upload my file, but it rejected it.
There is a file-size limit for submissions -- 500KB.

The most likely cause of this is that your file is too big, and this generally happens because your screen shots are huge (too high a resolution). Think about the number of pixels... Try editing your screen shot (e.g. in Microsoft Paint or ColorSync Utility on mac) to reduce its quality/number of pixels/size.

Working Remotely
How do I access my Z drive from home?
You can use FTP (file transfer protocol) to access your home directory. You'll need a secure version of FTP to connect to csa.bu.edu or csa2.bu.edu and I recommend this standalone version http://winscp.net/download/winscp407.exe (if you want multi-language, you'll need the installation version which can be found at http://winscp.net/eng/download.php)

Running winscp is a bit like putty, you enter a host (csa or csa2) and use your account to log in.

  • After you log in, you'll see your local drive on the left, and your home directory on the right.
  • Simply drag the files from right to left if you want to download, or from left to right if you want to upload.

It's also possible to mount your home directory as Z drive on your laptop, but it requires additional setup and I don't know how to do it. If you're interested, please ask the tech people at the computing lab.

Screen Shots
How do I take a screen shot on a Mac?
Try:
command-shift-4 --> this gives you cross-hairs to select an area to copy
command-shift-4, then space --> this will then take a picture of the "current" window.

You can then drag these pictures into a word document.
