Disconnection
This error indicates that the connection to the remote host
computer has been lost.
There may be problems with the configuration or the physical setup of
either your or the remote host computer's network connection.
It may also be that the remote host computer has been rebooted, which
has disconnected your computer from the host.
Usually problems of this kind are temporary, and you can try again after
waiting for a while. If this does not help, check your local network,
and if necessary, contact also the system administrator of the remote
host computer.
