NAME

radvdump - dump router advertisements

SYNOPSIS

radvdump [ -vhfe ] [ -d debuglevel ] [ -u username ]

DESCRIPTION

radvdump prints out the contents of incoming router advertisements sent by radvd or some other software implementing (parts of) "Neighbor Discovery for IP Version 6 (IPv6)" (RFC 4861).

OPTIONS

For every one character option there is also a long option, which is listed right next to the "short" option name:

-v, --version

Displays the version of radvdump and then aborts.

-h, --help

Displays a short usage description and then aborts.

-f, --file-format

Output received router advertisements in the format of the radvd configuration file. Since radvd 0.9, this is the default and the switch is provided for backward compatibility only.

-e, --exclude-defaults

Exclude default valued options from configuration file format. This option is ignored if option -f is not set.

-d debuglevel, --debug debuglevel

With this option you turn on debugging information. The debugging level is an integer in the range from 1 to 4, from quiet to very verbose. A debugging level of 0 completely turns off debugging.

The default debugging level is 0.

-u username, --username username

If specified, drops root privileges and changes user ID to username and group ID to the primary group of username. This is recommended for security reasons. Defaults to "nobody", pass "" or "root" to not drop privileges by default.
