NAME

sstcpcli - DTN simple TCP convergence layer input task

SYNOPSIS

stcpcli local_hostname[:local_port_nbr]

DESCRIPTION

stcpcli is a background "daemon" task comprising 1 + N threads: one that handles TCP
connections from remote stcpclo tasks, spawning sockets for data reception from those
tasks, plus one input thread for each spawned socket to handle data reception over that
socket.

The connection thread simply accepts connections on a TCP socket bound to local_hostname
and local_port_nbr and spawns reception threads. The default value for local_port_nbr, if
omitted, is 4556.

Each reception thread receives bundles over the associated connected socket. Each bundle
received on the connection is preceded by a 32-bit unsigned integer in network byte order
indicating the length of the bundle. The received bundles are passed to the bundle
protocol agent on the local ION node.

stcpcli is spawned automatically by bpadmin in response to the 's' (START) command that
starts operation of the Bundle Protocol; the text of the command that is used to spawn the
task must be provided at the time the "stcp" convergence layer protocol is added to the BP
database. The convergence layer input task is terminated by bpadmin in response to an 'x'
(STOP) command. stcpcli 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" stcpcli 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 stcpcli.

"1" stcpcli 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 stcpcli.
