Warning
titleRemote server access requirements
Tip

Since you are attending this class remotely, you will need to use the UT VPN service or create a public/private key pair in order to access the shared compute environment.

How to set up a public/private key pair is cescribed here:  POD Resources and Access#PasswordlessAccessviaSSH/SFTP. Once you have created the key pair, please email me the public key file (or its contents).

With this account you can ssh into one of the following servers, according to the assignments above:

  • gsafcomp01.ccbb.utexas.edu
  • gsafcomp02.ccbb.utexas.edu
  • gsafcbig01.ccbb.utexas.edu

For example:

Once you have satisfied the remote access requirements, here's how to access the servers:

Code Block
# If you have the UT VPN active:
ssh student50@gsafcomp02.ccbb.utexas.edu

# or, from outside the UT campus network, using public key encryption
ssh -p 222 student50@gsafcomp02.ccbb.utexas.edu

If your terminal has a dark background, the default shell colors can be hard to read. Execute this line to display directory names in yellow (and put it in your ~/.profile login script)

Code Block
languagebash
export LS_COLORS=$LS_COLORS:'di=1;33:'

Desktop file browsing

Desktop file browsing is optional, but can come in handy for editing script files remotely.

You can connect your Mac or Windows laptop to your Home directory using the Samba network file system protocol. Once this is set up, you can use your favorite desktop code editing GUI to open, edit, and save files to your home directory.

Tip

Desktop file browsing using the Samba protocol is only available from the UT campus network . If you are attending this class remotely, so you will need to use the UT VPN service (described here: FAQ#HowtosetuptheUTVPNservice).

An alternative to Desktop file browsing is to use a text editor that has remote file editing capabilities using SSH (e.g. Komodo Edit, Sublime text edit (both Windows & Mac) and Notepad++ (Windows only).

Tip
titleTip

Make sure you save script files with Unix/Linux line endings (linefeed only, not carriage_return + linefeed as is the Windows default).
