Fugu Issues

If you're using Fugu and get the following error:

Follow this procedure:
  1. In the Fugu pulldown menu at the top, select Preferences...
  2. Select the Known Hosts tab
  3. Locate dfs.lsa.umich.edu in the list, and click it to select it
  4. Click the Delete button
  5. Click the Save button (IMPORTANT!)
  6. Click the red circle to close the window

Now try connecting again. This time you will see a new warning that looks like this:


Just click the Continue button.

SECURITY WARNING

The purpose of the warning you saw that brought you to this webpage is to inform you that the SSH keys on the server are different than the one you previously had. Normally this only happens when a server is upgraded or experiences other normal changes that may regenerate the SSH host key. It is possible, however, that an attacker may have compromised the server and replaced the good SSH key with their own which might allow them to decrypt the traffic, including your password. In most cases it is OK to follow the procedure outlined above, but you should keep this warning in mind if you're concerned about security - which you should be.

Didn't fix the problem?

If the problem wasn't fixed by the above procedure, quit and restart Fugu and repeat it. Be sure that you click the Save button. If the problem still persists, you can delete your entire known_hosts file by opening up /Applications/Utilities/Terminal, then typing rm ~/.ssh/known_hosts .
