PROGRAM:
NAME
synos - guess operating system from TCP SYN fingerprint
SYNOPSIS
synos [--mtu mtu] [--db path] syn-fingerprint
DESCRIPTION
synos takes a SYN fingerprint, in the format described for the CLIENT_SYNFP environment
variable in the avenger(1) man page, and outputs a guess as to the type of the client
operating system. synos makes use of the OpenBSD SYN fingerprint database (which is also
repackaged with Mail Avenger).
OPTIONS
--mtu val
Certain operating systems set the initial TCP window size based on the maximum
transmission unit, or MTU, of the network. For such operating systems, synos usually
checks the window size using both the client's MSS option plus 40 bytes (for TCP and
IP headers), or a hard-coded MTU, which defaults to 1,500 bytes. If either value
works, the fingerprint is considered to match the operating system. You can change
the value 1,500 by specifying this option. A value of 0 tells synos to use only the
value derived from the MSS option.
--db file
Specifies an alternate location for the SYN fingerprint database.
