NAME

ocd − outbound connection daemon used by DDFA software

SYNOPSIS

ocd -nnode_name -fpseudonym [-b board_no] [-p port_no] [-c config_file]

DESCRIPTION

The Outbound Connection Daemon (ocd) is part of the HP Datacommunications and Terminal Controller (DTC) Device File Access (DDFA) software.  It manages the connection and data transfer to the remote DTC port.  It can be spawned from the Dedicated Port Parser (dpp) or run directly from the shell. 

For performance reasons, ocd does not have a debug mode; however, a version called ocdebug with debug facilities is available (see ocdebug(1m) for more information.

See ddfa(7) for more information on how to configure and install the DDFA software, and for an explanation of how it works. 

ocd recognizes the following options and command-line arguments:

-nnode_name Mandatory.  This is the IP address of the terminal server or the port. 

-fpseudonym Mandatory.  This is the absolute or relative path to the device file which is linked by the software to the reserved pty.  Applications use the pseudonym, not the dynamically allocated pty slave. 

-bboard_no Optional.  This refers to the board number of the DTC.  If it is omitted, the port number option must contain the full TCP service port address.  -b and -p must not be used if the IP address given in -n is the IP address of a port. 

If the -n option explicitly names a DTC port, the -b option is not needed. 

-pport_no Optional.  This is the DTC port number.  If the -b option is omitted, the port number must be the TCP service port address that will be used by the software to access the port.  If the value is omitted, the value 23 (Telnet) is used by default. 

-cconfig_file Optional.  This is the name (including the absolute path) of the configuration file used to profile the DTC port.  If this value is omitted, the default values specified in the default pcf file (/etc/newconfig/ddfa/pcf) are used.  If the pcf does not exist, an error messageis be logged, and the following values are used (note that the values for open_tries and open_timer are different from the default values):

telnet_mode:     enable
timing_mark:     enable
telnet_timer:    120
binary_mode:     disable
open_tries:      0
open_timer:      0
close_timer:     0
status_request:  disable
status_timer:    30
eight_bit:       disable
tcp_nodelay:     enable

ocd logs important messages and error conditions to /usr/adm/syslog.
