ramd — Route Administration Manager Daemon (RAMD) for IPv6


/usr/sbin/ramd [-C] [-N] [-c] [-f config_file] [-n] [-q] [-t trace_options] [trace_file]


ramd is a routing daemon that manages routing for IPv6. ramd handles RIPng, BGP, and IS-IS routing protocols. ripngd, bgpd, and isisd are referred to as routing daemons.

ramd can be configured using the configuration file /etc/ramd.conf. Upon startup, ramd reads the configuration file and spawns the routing daemons, if it is configured. However, the command-line option trace_file is applicable only to ramd.

ramd maintains a routing table in user space and synchronizes it with the HP-UX kernel routing table. ramd periodically checks the kernel interface table and the route table for any updates or changes. It notifies the corresponding daemons about the updates.


ramd supports the following command-line options:


Parses the configuration file for syntax errors and terminates ramd. ramd exits with a status 0 if the configuration file contains no errors. If the configuration file contains errors, ramd exits with a non-zero value. ramd prints the configuration file errors, if any, to the standard output.


Specifies that ramd runs as a normal process and not as a daemon process.


Parses the configuration file for syntax errors and terminates ramd. It leaves a dump file, /var/tmp/ramd/ramd.dump, if the configuration file does not have any syntax errors.

-f config_file

Specifies an alternate configuration file to be used by ramd. By default, ramd uses /etc/ramd.conf.


Specifies that ramd does not modify the kernel forwarding table.


Suppresses the stderr messages of ramd and routing daemons. Using this option, ramd can suppress the informational messages that are normally printed to the standard output, and log error messages through syslogd(1M). By default, syslog errors are logged in /var/adm/syslog/syslog.log.

-t trace_options

Specifies a comma-separated list of trace options to be enabled during startup. A space cannot be entered between this option and its arguments.

This option can be used to trace events that occur before the configuration file is parsed, such as determining the interface configuration and reading routes from the kernel.

See the ramd.conf(4) manpage for information on tracing and valid trace options.

The trace options, no, cannot be specified with the -t command-line option.


Specifies the name of the file used by the daemon to log tracing information.

Signal Processing

The following signals are used to control ramd:


Specifies ramd to reread the configuration file. ramd reads the configuration file and reconfigures its policies. ramd also checks if it must start and stop the protocol daemons.


Specifies that the current state of ramd is written to /var/tmp/ramd/ramd.dump.


Graceful shutdown. On receipt of SIGTERM, ramd attempts a graceful shutdown.

ramd removes all protocol routes from the HP-UX 11i v1 kernel routing table on receiving SIGTERM. Interface routes and static routes remain with the retain option. SIGKILL can be used to terminate ramd with all the routes intact. It may be necessary to repeat the SIGTERM once or twice if ramd delays its termination.


Toggle tracing. If tracing is enabled, ramd suspends tracing and closes the trace file. If tracing is disabled, ramd opens the trace file and initiates tracing. This is useful for moving trace files.

SIGUSR1 signal cannot be used, if ramd does not enable tracing in the configuration file.


Checks for interface changes. On receipt of SIGUSR2, ramd rescans the kernel interface list for changes.


To use an alternate configuration file for ramd instead of the default /etc/ramd.conf configuration file, invoke ramd as follows:

/usr/sbin/ramd -f /tmp/sample.conf

To log tracing related information to the trace options iflist and parse, invoke ramd as follows :

/usr/sbin/ramd -t parse,iflist /tmp/ramd_log

ramd logs the trace information that is related to the configuration file and the kernel interface table, in the log file /tmp/ramd_log.
