Can’t Log in to cheerleading.dsc.umich.edu (Connection Times Out or is Refused)

Environment

Websites hosted by ITS Web Hosting in AFS.

Issue

People cannot log in to cheerleading.dsc.umich.edu using SSH or SFTP.  They receive a "connection refused, "connection timed out", "unable to connect to server", or similar error message.

Resolution

At 7:30 am April 4, 2023, cheerleading.dsc.umich.edu was permanently shut down.

  • Solution 1: Log in to umpire.dsc.umich.edu instead. umpire.dsc.umich.edu supports both SSH and SFTP and is accessible from everywhere in the world, but it requires Duo for most connections, which may not work with all SFTP clients. For a list of SFTP clients that will work with umpire.dsc.umich.edu, refer to Can’t Log In to sftp.itd.umich.edu (SFTP Client Errors or Problems With Duo).
  • Solution 2: Use SFTP to log into sftp.web.itd.umich.edu from on-campus or the VPN.  sftp.web.itd.umich.edu does not require Duo and should work with all SFTP clients, but it supports only SFTP (not SSH). Note: sftp.web.itd.umich.edu is different than sftp.itd.umich.edu. sftp.itd.umich.edu does require Duo.
     
  • Solution 3: Refer to Set up CI/CD or Other Automatic Updates Without Duo for AFS-Based Websites for how to set up a special sponsored uniqname that can be used worldwide with both SSH and SFTP and without Duo for automating updates to AFS-based websites. 

Additional Information

Connecting to SFTP:  Any connection using SFTP protocol will require an on campus connection, or the use of the U-M VPN.

cheerleading.dsc.umich.edu was a Red Hat Enterprise Linux 6 server.  Its replacement, umpire.dsc.umich.edu, is a Red Hat Enterprise Linux 8 server that supports newer website development software tools.

Can’t Log In to sftp.itd.umich.edu (SFTP Client Errors or Problems With Duo)
People cannot log in to sftp.itd.umich.edu via SFTP despite having an AFS home directory and using the correct username and password, but they are able to log in using SSH. The SFTP client they are using may not support keyboard-interactive authentication, which is required for Duo. Switch to another SFTP client instead (such as Cyberduck) or use the SFTP server sftp.web.itd.umich.edu from a university network or the U-M VPN.
