NAME
dpp - dedicated ports parser used by DDFA software SYNOPSIS
dp_file log_file] ocd_program] DESCRIPTION
The Dedicated Ports Parser command is part of the Data Communications and Terminal Controller (DTC) Device File Access (DDFA) software. It parses the Dedicated Ports file and spawns an Outbound Connection Daemon for each valid entry in the file. can be run from the shell or it can be included in a system initialization script to automatically run the DDFA software each time the sys- tem is booted. See ddfa(7) for more information on how to configure the DDFA software and for an explanation of how it works. Options and Arguments recognizes the following options and arguments: dp_file It must be the first argument. The file (dp_file) defines the link between a terminal server port and the device file used by applications to access the port. Its contents must meet the specifications given in dp(4). If it is modified, must be run again to activate the changes. Specify that the file should be parsed and that all incorrect entries should be logged without invoking any processes. This option is useful for debugging the file before running it properly. The option is ignored if the option is used. Specify that the device file corresponding to each valid entry in the file should be removed before launching for each valid entry. Removing the device file eventually causes an process (if any is running) to shutdown. If this option is omitted, no device files will be removed and, there- fore, only newly added valid entries in the file will have launched. normally creates and removes devices files. However, if the process is killed incorrectly, such as with the device file may remain. If the system is rebooted, the option can be specified to restart all file entries cor- rectly. If a corresponding no longer exists, the device file is removed by any following invocation of that requires the same device file. In order to shutdown every running without restarting them, the following command can be executed: Specify where to log error messages. If this option is omitted, all error messages are logged to standard output. If the specified file does not already exist, it is created. The file must be nonexecutable and readable by Specify the path for an outbound connection daemon. The default path for is The daemon must be executable. DIAGNOSTICS
Error messages are logged for bad arguments, bad file entries, and creation errors. By default, they are logged to standard output. If the option is used, they are appended to the specified log file. The file either does not exist or cannot be accessed with the current access privileges. The log file cannot be created, either because of an invalid path or because of insufficient access privileges. The log file cannot be accessed, either because of an invalid path or because of insufficient access privileges. The log file must be readable by everyone. The program specified in the option either does not exist or is not an executable file with the current access privileges. The option has been specified and the device file exists, but it cannot be purged because of insufficient access privileges. The default cannot be executed, either because of insufficient access privileges or because it has not been correctly installed. The file entry specified does not have a valid IP address. The port specified is either not a decimal value or a string composed of or characters. The board specified is either not a decimal value or a string composed of or characters. The program specified cannot be started because there are no processes available on the system. The device file specified cannot be created, either because of an invalid path or because of insufficient access privileges. The specified configuration file cannot be read, either because of an invalid path or because of insufficient access privileges. The specified logging level is not in the range 0 to 3. The specified node name does not exist or does not have an entry in a name database. WARNINGS
To ensure that commands (such as ps) display the correct device file name (that is, the pseudonym), all pseudonyms should be placed into the directory If pseudonyms are not specified for placement in this directory, the correct display of device file names with many commands is not guaranteed. In addition, to ensure that commands (such as and work correctly, each pseudonym must be unique in its first 17 characters (including the directory prefix If pseudonyms are not unique in their first 17 characters, the correct functioning of many commands is not guaranteed. Also, in order to reliably handle timing mark negotiations (and ensure that files printing on a printer attached to a terminal server have been completely flushed to that printer), the following line must be added near the end of each printer interface script for printers attached to a terminal server: The printer interface scripts reside in the directory The line must be added just prior to the final 'exit' command in each printer inter- face script. If this line is not added as specified, the printing reliability of printers attached to a terminal server is not guaranteed. Finally, should be killed using Do not use for this purpose as it does not remove the device file. verifies the validity of an existing pseudonym before trying to use it. and use data stored in the file to verify whether a process still owns a pseudonym before taking it over. If finds an unowned pseudonym, it uses it. FILES
