hpcwoods Connection Issues

Posted on: April 9th, 2018 by bnpharr

The new hpcwoods has a newer version of SSH, which no longer allows certain insecure algorithms. Unfortunately, this means the SSH Secure Shell client for Windows will no longer work with hpcwoods.

This is not surprising, as it hasn’t been updated in years. We have been discouraging its use for several months now, due to the fact it did not correctly handle forced password resets.

Windows users should use the PuTTY SSH client. For file transfer, we recommend FileZilla.

hpcwood’s SSH host key also changed as a result of the upgrade. PuTTY users will be presented with a dialog at connection time. Mac and Linux users will need to remove the old key before attempting to connect to hpcwoods:
ssh-keygen -R
