I'm doing something in my build to get this output in my travis tests. It hangs since my test cannot accept or decline, and the test fails:

```
The authenticity of host 'heroku.com (50.19.85.154)' can't be established.
RSA key fingerprint is 8b:48:5e:67:0e:c9:16:47:32:f2:87:0c:1blah.
Are you sure you want to continue connecting (yes/no)? 

```

I had a similar problem with github.com but I changed to read only urls. Instead of dealing with this problem for every x.com that hosts a git repo, is there a way to have travis just auto authorize any auth request via ssh that is made? I can do this locally via something like this: <http://debuggable.com/posts/disable-strict-host-checking-for-git-clone:49896ff3-0ac0-4263-9703-1eae4834cda3> is it possible to set something like that up on Travis?
