ssh 2.0.13

[Jean Caron]

Hello,

I get the following error while trying to connect between to boxes, both
using ssh 2.0.13.

Disconnected; authentication error (No further authentication methods
available.)

I set them up exactly the same, minutes apart. What's really strange is
that sometimes it establlishes the session okay and sometimes I get this
error...?

Is this an obvious one to anyone ?

Thanks,
Jean
