NAME

       stcpclo - DTN simple TCP convergence layer adapter output task

SYNOPSIS

       stcpclo remote_hostname[:remote_port_nbr]

DESCRIPTION

       stcpclo is a background "daemon" task that connects to a remote node's TCP socket at remote_hostname and
       remote_port_nbr.  It then begins extracting bundles from the queues of bundles ready for transmission via
       TCP to this remote bundle protocol agent and transmitting those bundles over the connected socket to that
       node.  Each transmitted bundle is preceded by a 32-bit integer in network byte order indicating the
       length of the bundle.

       If not specified, remote_port_nbr defaults to 4556.

       Note that stcpclo is not a "promiscuous" convergence layer daemon: it can transmit bundles only to the
       node to which it is connected, so scheme configuration directives that cite this outduct need only
       provide the protocol name and the outduct name as specified on the command line when stcpclo is started.

       stcpclo is spawned automatically by bpadmin in response to the 's' (START) command that starts operation
       of the Bundle Protocol, and it is terminated by bpadmin in response to an 'x' (STOP) command.  stcpclo
       can also be spawned and terminated in response to START and STOP commands that pertain specifically to
       the STCP convergence layer protocol.

EXIT STATUS

       "0" stcpclo terminated normally, for reasons noted in the ion.log file.  If this termination was not
           commanded, investigate and solve the problem identified in the log file and use bpadmin to restart
           the STCP protocol.

       "1" stcpclo terminated abnormally, for reasons noted in the ion.log file.  Investigate and solve the
           problem identified in the log file, then use bpadmin to restart the STCP protocol.

FILES

       No configuration files are needed.

ENVIRONMENT

       No environment variables apply.

DIAGNOSTICS

       The following diagnostics may be issued to the ion.log log file:

       stcpclo can't attach to BP.
           bpadmin has not yet initialized Bundle Protocol operations.

       No such stcp duct.
           No STCP outduct with duct name matching remote_hostname and remote_port_nbr has been added to the BP
           database.  Use bpadmin to stop the STCP convergence-layer protocol, add the outduct, and then restart
           the STCP protocol.

       CLO task is already started for this duct.
           Redundant initiation of stcpclo.

       Can't get IP address for host
           Operating system error.  Check errtext, correct problem, and restart STCP.
