I found the instructions on kerneltrap's mail archive: "scp batch mode?" to be insightful an useful, however when I issue the command to close the connection
# Bring the connection down.
ssh -S /tmp/ssh_socket -O exit dummy
my ssh complains that it does not support the -O
(that is upper case o) option.
My question is: Is it sufficient to delete the /tmp/ssh_socket
, to properly close the connection, or am I missing some important step here?
