NAME¶
udplsi - UDP-based LTP link service input task
SYNOPSIS¶
udplsi {
local_hostname | @}[:
local_port_nbr]
DESCRIPTION¶
udplsi is a background "daemon" task that receives UDP
datagrams via a UDP 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"
- udplsi 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
udplsi.
- "1"
- udplsi 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 udplsi.
FILES¶
No configuration files are needed.
ENVIRONMENT¶
No environment variables apply.
DIAGNOSTICS¶
The following diagnostics may be issued to the
ion.log log file:
- udplsi can't initialize LTP.
- ltpadmin has not yet initialized LTP protocol operations.
- LSI task is already started.
- Redundant initiation of udplsi.
- LSI can't open UDP socket
- Operating system error. Check errtext, correct problem, and restart
udplsi.
- LSI can't initialize socket
- Operating system error. Check errtext, correct problem, and restart
udplsi.
- LSI can't create receiver thread
