NAME

       dccplso - DCCP-based LTP link service output task

SYNOPSIS

       dccplso {remote_engine_hostname | @}[:remote_port_nbr] remote_engine_nbr

DESCRIPTION

       dccplso is a background "daemon" task that extracts LTP segments from the queue of
       segments bound for the indicated remote LTP engine, encapsulates them in DCCP datagrams,
       and sends those datagrams to the indicated DCCP port on the indicated host.  If not
       specified, port number defaults to 1113.

       Each "span" of LTP data interchange between the local LTP engine and a neighboring LTP
       engine requires its own link service output task, such as dccplso.  All link service
       output tasks are spawned automatically by ltpadmin in response to the 's' command that
       starts operation of the LTP protocol, and they are all terminated by ltpadmin in response
       to an 'x' (STOP) command.

EXIT STATUS

       "0" dccplso 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 ltpadmin to restart dccplso.

       "1" dccplso terminated abnormally, for reasons noted in the ion.log file.  Investigate and
           solve the problem identified in the log file, then use ltpadmin to restart dccplso.

FILES

       No configuration files are needed.

ENVIRONMENT

       No environment variables apply.

DIAGNOSTICS

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

       dccplso can't initialize LTP.
           ltpadmin has not yet initialized LTP protocol operations.

       No such engine in database.
           remote_engine_nbr is invalid, or the applicable span has not yet been added to the LTP
           database by ltpadmin.

       LSO task is already started for this engine.
           Redundant initiation of dccplso.

       LSO can't create idle thread.
           Operating system error.  Check errtext, correct problem, and restart dccplso.

       LSO can't open DCCP socket. This probably means DCCP is not supported on your system.
           Operating system error. This probably means that you are not using an operating system
           that supports DCCP. Make sure that you are using a current Linux kernel and that the
           DCCP modules are being compiled. Check errtext, correct problem, and restart dccplso.

       LSO can't connect DCCP socket.
           Remote host's dccplsi isn't listening or has terminated. Restart dccplsi on the remote
           host and then restart dccplso.

       Segment is too big for DCCP LSO.
           Configuration error: segments that are too large for DCCP transmission (i.e., larger
           than 65535 bytes) are being enqueued for dccplso.  Use ltpadmin to change maximum
           segment size for this span.
