NAME¶
dccplsi - DCCP-based LTP link service input task
SYNOPSIS¶
dccplsi {
local_hostname | @}[:
local_port_nbr]
DESCRIPTION¶
dccplsi is a background "daemon" task that receives DCCP
datagrams via a DCCP socket bound to
local_hostname and
local_port_nbr, extracts LTP segments from those datagrams, and passes
them to the local LTP engine. Host name "@" signifies that the host
name returned by
hostname(1) is to be used as the socket's host name.
If not specified, port number defaults to 1113.
The link service input task is spawned automatically by
ltpadmin in
response to the 's' command that starts operation of the LTP protocol; the
text of the command that is used to spawn the task must be provided as a
parameter to the 's' command. The link service input task is terminated by
ltpadmin in response to an 'x' (STOP) command.
EXIT STATUS¶
- "0"
- dccplsi 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 dccplsi.
- "1"
- dccplsi 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 dccplsi.
FILES¶
No configuration files are needed.
ENVIRONMENT¶
No environment variables apply.
DIAGNOSTICS¶
The following diagnostics may be issued to the
ion.log log file:
- dccplsi can't initialize LTP.
- ltpadmin has not yet initialized LTP protocol operations.
- LSI task is already started.
- Redundant initiation of dccplsi.
- LSI 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 dccplsi.
- LSI can't initialize socket.
- Operating system error. Check errtext, correct problem, and restart
dccplsi.
- LSI can't create listener thread.
- Operating system error. Check errtext, correct problem, and restart
dccplsi.
