About You
Tell us a bit about yourself, such as:
- your lab
- research interests
- computational background, including any programming languages you use
- why you're interested in advanced bash scripting
Setup
You'll be using the BRCF "GSAF POD", a set of 3 compute servers attached to a large, shared storage server.
Accounts
We have set up 50 "student" accounts, named student01 , student02 ... student50 . You have each been assigned one...
The super-secret password for all these accounts is: AdvancedBash-Training
These credentials are active for the next few days, but will be de-activated at the end of this week (Friday August 23).
Servers
With this account you can ssh into one of the following servers (please divide yourselves among them):
- gsafcomp01.ccbb.utexas.edu
- gsafcomp02.ccbb.utexas.edu
- gsafcbig01.ccbb.utexas.edu
For example:
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
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
Tip
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)
export LS_COLORS=$LS_COLORS:'di=1;33:'
Desktop file browsing
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.
Desktop file browsing using the Samba protocol is only available from the UT campus network. If you are attending this class remotely, 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
Make sure you save script files with Unix/Linux line endings (linefeed only, not carriage_return + linefeed as is the Windows default).
On Windows
- Bring up Windows Explorer (e.g. Ctrl- <Windows key>)
- Select This PC → Computer tab → Map network drive
- In the Map Network Drive dialog box
- Select a drive letter (e.g. W: )
- In the Folder text box, enter: \\gsafstor01.ccbb.utexas.edu\users
- Check the Connect using different credentials checkbox
- Select Finish
- In the Enter network credentials dialog
- Enter your student account name and password AdvancedBash-Training
- Select OK
- You should now see a users (\\gsafstor01.ccbb.utexas.edu) (W:) item under This PC in Windows Explorer
On Macs
- Bring up the Finder
- Select Finder → Go → Connect to Server... (or just type ⌘-K )
- In the text box up top, enter: smb://gsafstor01.ccbb.utexas.edu/users
- Click on Connect
- Select Registered User
- Enter your student account name and password AdvancedBash-Training
- You should have a new window open with the contents of the Samba share. It will also be listed under Locations in the Finder sidebar
