I'm using a Mac, and I am having ussieus when I try to connect with SSH in my account.

When I type: "ssh [my user name]@[myusername].webfactional.com" I receive the following message:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@       WARNING: POSSIBLE DNS SPOOFING DETECTED!          @

The RSA host key for XXXXX.webfactional.com has changed,

Typically you would not see those issues unless you have recently migrated from one server to another server or the IP Address of the server has changed. Since an IP Address change on the server is very rare you may have recently migrated servers.

You can either remove the existing key via the following command and trying again or open a support ticket so we can investigate farther.

ssh-keygen -R <host name="">

I tried to remove the existing key, but it didn't work. I'm still getting the same error.

I already open a ticket, but no one answered me.

I don't think we've received your ticket. Try sending an email to support@webfaction.com from your account's authorized email address.

It would be great if WebFaction could send us a notification when our account is being migrated between servers. I received this error message today and the control panel suggests that I am on a different server now, but I don't know when that change happened. Having some notice or confirmation would be nice given that it looks very similar to a serious attack!

A notice is actually sent out 10 days before the migration. One was sent to you on 2017-03-28

Ah, good to know! It was filtered out by my email client because it was sent to two addresses, but I'll be sure to fix that. Thanks!
