I am trying to connect from one Debian box to another using ssh. When I attempt to login to the remote machine, I get an error message saying "connection closed". This was working yesterday. If I use the "-vvv" flag, this is the last debug output I see:
debug3: authmethod_is_enabled keyboard-interactive
debug1: Next authentication method: keyboard-interactive
debug2: we sent a keyboard-interactive packet, wait for reply
Connection closed by 192.168.0.101
Any ideas what could be happening? I upgraded both Debain machines yesterday, but not the ssh package.
