NAME

ramond - IPv6 Router Advertisement MONitor Daemon

SYNOPSIS

ramond [ -c configfile ] [ -d ]

ramond -h

DESCRIPTION

This manual page documents briefly the ramond command.

ramond is a daemon program monitoring IPv6 router advertisement packets. When an advert is reveived, a configurable action occurs.

ramond was designed to “clear” (by sending spoofed zero lifetime adverts) rogue routes sent by users running 6to4 gateways on a campus network. Actions are scriptable. Almost all the available information is passed to a script via environmental variables (see the ENVIRONMENT section for details).

OPTIONS

The program follows the usual GNU command line syntax, without long options. A summary of options is included below.

-c configfile: Sets the path to the ramond configuration file. Default is /etc/ramond.conf
-d: Do not daemonize.
-h: Show summary of options.

FILES

/etc/ramond.conf: The system-wide configuration file to control the behaviour of ramond. See ramond.conf(5) for further details.

ENVIONMENT

This section details the environment variables set by ramond when it runs a user-configured script.

PREFIX: The advertised prefix, or null
PREFIX_LEN: The length of the advertised prefix, or null
SOURCE_ADDR: The IPv6 source address of the packet
SOURCE_MAC: The MAC source address of the packet
INTERFACE: The interface which the packet was received on
