NAME

       udpcli - UDP-based BP convergence layer input task

SYNOPSIS

       udpcli local_hostname[:local_port_nbr]

DESCRIPTION

       udpcli is a background "daemon" task that receives UDP datagrams via a UDP socket bound to local_hostname
       and local_port_nbr, extracts bundles from those datagrams, and passes them to the bundle protocol agent
       on the local ION node.

       If not specified, port number defaults to 4556.

       The convergence layer input task 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 "udp" 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.  udpcli can
       also be spawned and terminated in response to START and STOP commands that pertain specifically to the
       UDP convergence layer protocol.

EXIT STATUS

       "0" udpcli  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
           udpcli.

       "1" udpcli  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 udpcli.

FILES

       No configuration files are needed.

ENVIRONMENT

       No environment variables apply.

DIAGNOSTICS

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

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

       No such udp duct.
           No UDP induct matching local_hostname and local_port_nbr has been added  to  the  BP  database.   Use
           bpadmin  to  stop  the  UDP  convergence-layer  protocol,  add  the  induct, and then restart the UDP
           protocol.

       CLI task is already started for this duct.
           Redundant initiation of udpcli.

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

       Can't open UDP socket
           Operating system error.  Check errtext, correct problem, and restart UDP.

       Can't initialize socket
           Operating system error.  Check errtext, correct problem, and restart UDP.

       udpcli can't create receiver thread
           Operating system error.  Check errtext, correct problem, and restart UDP.
