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.
