This article gives instructions on how to remotely access computer resources at Florida Tech, such as code01.fit.edu, using SSH and SFTP.

SSH, which stands for Secure SHell, allows remote users to access servers over an encrypted communication session. SFTP is a Secure File Transfer Protocol and allows files to be downloaded from and uploaded to remote servers. SSH is the secure method to access files and run remote sessions.

6. What are some common problems?

Below are the two most common issues encountered when attempting to connect to code01.fit.edu:

  • Using an upper case letter in the username. Usernames are case sensitive on Unix and Linux systems, such as code01. Therefore, there is a difference between 'johndoe1234' and 'JohnDoe1234', with the latter not being a valid username. Entering an invalid username too many times will cause your IP to be blocked, as described in the next issue.
  • Entering a bad username and/or password too many times. After 10 failed login attempts (for any reason), if you are connecting from an off-campus computer, your public IP will be blocked. If this happens, you will need to create a support request to have it unblocked.

7. Where can I find help with Unix or Linux commands?

There are lots of Unix and Linux help sites on the web, try a search on Google.

8. How can I run remote graphic applications on my computer?

Graphical applications on code01.fit.edu can be run locally on your computer by using an X window server. Linux systems with an installed GUI (Graphical User Interface) normally have this installed. However, on Windows and macOS, this is achieved using an application such as VcXsrv, MobaXterm, or Xming for Windows, or XQuartz for macOS.
