NAME <\/a> <\/h2>\n

nfnl_osf \u2212 OS fingerprint loader utility<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

nfnl_osf -f<\/b> fingerprints<\/i> [ -d<\/b> ]<\/p>\n

DESCRIPTION <\/a> <\/h2>\n

The nfnl_osf<\/b> utility allows to load a set of operating system signatures into the kernel for later matching against using iptables\u2019 osf<\/b> match.<\/p>\n

OPTIONS <\/a> <\/h2>\n

-f<\/b> fingerprints<\/i><\/p>\n

Read signatures from file fingerprints<\/i>.<\/p>\n\n\n
<\/td>\n\n

-d<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Instead of adding the signatures from fingerprints<\/i> into the kernel, remove them.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

EXIT STATUS <\/a> <\/h2>\n

Exit status is 0 if command succeeded, otherwise a negative return code indicates the type of error which happened:<\/p>\n\n\n
<\/td>\n\n

-1<\/b><\/p>\n<\/td>\n

<\/td>\n\n

Illegal arguments passed, fingerprints file not readable or failure in netlink communication.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n

-ENOENT<\/b><\/p>\n

Fingerprints file not specified.<\/p>\n

-EINVAL<\/b><\/p>\n

Netlink handle initialization failed or fingerprints file format invalid.<\/p>\n

FILES <\/a> <\/h2>\n

An up to date set of operating system signatures can be downloaded from http:\/\/www.openbsd.org\/cgi-bin\/cvsweb\/src\/etc\/pf.os .<\/p>\n
