Computer Science Rlogin

Introduction

rlogin.cs.vt.edu is the primary Computer Science teaching resource. It consists of multiple Linux machines with standard development software usable by any Computer Science course.

Access

You can log into rlogin.cs.vt.edu using either your CS username/password OR your VT username/password.

Using just your VT account

Non-CS affiliates (such as a non-CS major taking a CS class) can log in using just their VT username and password.

• This method only works if you do not have a CS account.
• You need a SSH client.
  • Linux and Mac machines generally already have an SSH client installed and ready to use from the command line.
  • Several SSH clients are available for Windows. We recommend installing either Microsoft's built-in SSH client: https://learn.microsoft.com/windows-server/administration/openssh/openssh_install_firstuse
• Run the following command
  • <username>@rlogin.cs.vt.edu replace <username> with your VT username
• You will be prompted for your VT password
• It will silently use your default VT Duo 2FA method. If you need to use an alternative Duo method, see VT's documentation: https://4help.vt.edu/sp?id=kb_article&sysparm_article=KB0010700&sys_kb_id=8377bde91bb4259063110f66624bcb3a&spa=1#ldap
• Once connected, we high recommend that you set up SSH key login Howto::SSH Key so you no longer need to use your VT password and Duo to log in every time.

Using your CS account

Once you have a CS account, access to rlogin.cs.vt.edu is slightly different.

• Using ssh <username>@rlogin.cs.vt.edu will prompt for your CS password, not your VT password.
• You can still use your VT password by running ssh <username>@vt.edu@rlogin.cs.vt.edu
  • Note: your CS account and VT account are different UIDs, and have separate permissions. Your CS account can not access files owned by the VT account and vice-versa.
