I'm facing this issue. i know there are so many topics regarding this. Actually I was unable to access the remote server for restarting the SSH service and removing the host key. Any help on this.
debug1: Enabling compatibility mode for protocol 2.0
debug1: Local version string SSH-2.0-OpenSSH_6.6.1p1 Ubuntu-2ubuntu2.8 ssh_exchange_identification: read: Connection reset by peer
Also I need to know the exact reason behind this.
