Warning: the DSA host key for '' differs from the key for the IP address &#03 (3 posts)

    I get following message when I connect.

    Warning: the DSA host key for '' differs from the key for the IP address ''. Offending key for IP in /Users/username/.ssh/known_hosts:10
    Are you sure you want to continue connecting?

    If I say yes, connection is successful, but I am not sure if it's causing a security issue for me. I have Fetch in another computer and does not give me the same warning when I connect to the same website by Fetch. I would appreciate suggestions. Thank you!

    At some point someone made an SSH or SFTP connection (using Fetch or some other program) from your computer to '', and your Mac's SSH software recorded the host key for Now when you connect the SSH software (which is called by Fetch) is noticing that's host key is different from the one that was saved. That could simply mean that the server administrators had to do some maintenance and they changed the host key. It could also mean that bad actors are pretending to be, and the change in host key is giving them away.

    If you are concerned I would contact the administrators of and ask them if they changed their SSH host key.
