# ramond(8)

IPv6 Router Advertisement MONitor Daemon

## 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)](/ramond.conf/5.md) 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
