SYNOPSIS
fpdns [ -d ] [ -f ] [ -F nchild ]
[ -p port ] [ -Q srcaddr ] [ -r retry ]
[ -s ] [ -S separator ] [ -t timeout ] [ -v ] [server(s)]
DESCRIPTION
fpdns is a program that remotely determines DNS server versions. It does this by sending
a series of borderline DNS queries which are compared against a table of responses and
server versions.
False positives or incorrect versions may be reported when trying to identify a set of
servers residing behind a load-balancing apparatus where the servers are of different
implementations, when a specific implementation behaves like a forwarder, behind a
firewall without statefull inspection or without Application Intelligence.
OPTIONS
-d Enable debugging. Off by default.
-D Check all authoritative servers of the specified domain name.
-f Force checking of CH TXT version. Off by default.
-F nchild

-p port
Port to query remote nameserver on. Default is 53.
-Q srcaddr
Set the source IP address to use.
-r retry
Number of attempt to retry fingerprints. Defaults to 1.
-s Short display form. Useful for surveys.
-S Separator. Defaults to " ".
-t timeout
