graceful - Closes the connection gracefully by sending a FIN (finished)
rather than RST to the remote host.
Socket Administration
You can have a maximum of 64 open (in use) sockets on a CSS concurrently. If
you issue a
socket connect command and do not issue a socket disconnect
command for that socket's file descriptor (saved in the ${SOCKET} variable),
then the socket remains open until you issue a
socket disconnect command with
that socket’s file descriptor as the value for the socket_number argument.
If you open sockets within a script, the sockets close automatically when the script
ends, unless you passed the
session argument in the socket connect command. If
you open sockets within a session, the sockets close when the session ends (user
logs out).
Use the show sockets command to list all the socket file descriptors that are
currently in use.
Table 8-2 describes the fields in the show sockets output.
Note
If a remote host times out or closes a socket, the socket architecture cleans up the
socket and removes it from the list of used sockets. This cleanup occurs only after
you attempt another transfer on a socket that the remote host has already closed.
Otherwise, the socket remains idle.
