[Fab-user] Strange behaviour with key based SSH login

[SL]

Hi,

I'm seeing some strange behaviour with key based SSH login, wonder if anybody can offer some advice

Have passwordless SSH, with key auth but am seeing ['my remote server] Login password for myuser:

I don't understand this, because if I ssh myself into this box without a key, then I'm immediately disconnected. It also wont accept any password and just keeps repeatedly asking.

I'm on a non standard port, but am setting this through env.port (and I think this is working on).

Any ideas on what the problem might be?

Thanks.
