Logging into the Amazon Cloud
-
These instructions will ONLY be relevant in class, as the Cloud will not be accessible from home in advance of the class.
-
On the cloud, we’re going to use the default username: ubuntu
Logging in with ssh (Mac/Linux)
Logging in
- Make sure the permissions on your certificate are secure. Use chmod on your downloaded certificate:
chmod 600 CBWCG.pem
- To log in to the node, use the -i command line argument to specify your certificate:
ssh -i CBWCG.pem ubuntu@cbw##.dyndns.info
(where ## is your assigned student number. Your student number is the number on your name badge. If your number is less than 10, please add 0 in front of it.)
Copying files to your computer
- To copy files from an instance, use scp in a similar fashion:
scp -i CBWCG.pem ubuntu@cbw##.dyndns.info:<file name> .
- Everything created in your workspace on the cloud is also available by a web server on your cloud instance. Simply go to the following in your browser:
http://cbw##.dyndns.info/ http://cbw#.dyndns.info/
Logging in with Putty (Windows)

File System Layout
When you log in, you’ll notice that you have two directories: CourseData and workspace.
-
The CourseData directory will contain the files that you’ll need to complete your lab assignments.
-
The workspace directory is where we will keep our temporary files. By default, we have around 40 GB available for our output files in the workspace directory. If you run out of space, you may need to delete some files from this directory.
