Frequently Asked Questions

Getting Started with Server Access

How do I connect to the CS department server?

You will use SSH (Secure Shell) to connect. Your login info will look like:

ssh your_username@odin.cs.csub.edu

Replace your_username with the one assigned to you.

What do I use if I’m on Windows?
  • Use PuTTY, a free SSH client for Windows
  • Enter odin.cs.csub.edu as the hostname
  • Use your assigned username to log in when prompted
What if I’m on a Mac or Linux?

Open your Terminal and type:

ssh your_username@odin.cs.csub.edu

Then enter your password when prompted.

It says “Connection refused” or “Timeout.” What do I do?
  • Check your internet connection
  • Make sure the hostname is spelled exactly: odin.cs.csub.edu
  • Try again later — the server may be temporarily down
  • Reach out to your instructor if the issue continues
My password isn’t showing when I type it. Is that normal?

Yes — SSH does not display any characters while you type your password. Just type it and press Enter.

How do I transfer files between my computer and the server?
  • On Mac or Linux, use the scp command:
  • scp myfile.c your_username@odin.cs.csub.edu:~/
  • On Windows, you can use tools like WinSCP or PuTTY's PSCP
Where can I get help?

Reach out during office hours or via email. For server-related issues, you may also contact the CS department's technical support team.
