NAME

6       hsen - hosts3d sensor
7

SYNOPSIS

9       hsen id interface/file [destination] [-p]
10

DESCRIPTION

12       hsen  is  a  packet  capture daemon which reads and sends packet header
13       information to Hosts3D, locally or remotely.  hsen also  equates  host‐
14       name  to  IP by reading DNS packets (UDP type A class IN standard query
15       response).  Multiple sensors can send information to multiple computers
16       running Hosts3D on the same subnet via broadcast.
17
18       id           Identify  packets from a specific hsen when multiple exist
19                    (1-255).
20
21       interface    Listen on interface (eth0, eth1, ppp0, wlan0, etc.); or
22
23       file         Read packets from pcap file.  Standard input  is  used  if
24                    file is "-".
25
26       destination  Hosts3D IP or broadcast address (default localhost).
27
28       -p           Enable promiscuous mode (default disable).

NOTES

31       Firewall  configuration:  hsen talks to Hosts3D via UDP port 10111.  If
32       hsen is running and Hosts3D is not, ICMP  Port  Unreachable  (UDP  port
33       10111)  may  be generated.  To capture packets from some interfaces, or
34       in promiscuous mode, you may have to start hsen as root  (sudo).   hsen
35       logs to syslog, check when troubleshooting.  Support only for IPv4.  IP
36       headers with options are ignored.  Support for packets with  optionless
37       GRE or VLAN 802.1Q encapsulation.
