NAME

6       onesixtyone - efficient SNMP scanner
7

SYNOPSIS

9       onesixtyone [options] <host> <community>
10

DESCRIPTION

12       onesixtyone  is  an  SNMP  scanner  which utilizes a sweep technique to
13       achieve very high performance. It can scan an entire class B network in
14       under  13  minutes.   It  can be used to discover devices responding to
15       well-known community names or to mount a dictionary attack against  one
16       or more SNMP devices.
17
18       onesixtyone  takes  a  different  approach  to  SNMP scanning. It takes
19       advantage of the fact that SNMP is a connectionless protocol and  sends
20       all  SNMP  requests  as  fast  as  it  can.  Then the scanner waits for
21       responses to come back and logs them, in a fashion similar to Nmap ping
22       sweeps.  By default onesixtyone waits for 10 milliseconds between send‐
23       ing packets, which is adequate for 100Mbs switched networks.  The  user
24       can  adjust this value via the -w command line option. If set to 0, the
25       scanner will send packets as fast as  the  kernel  would  accept  them,
26       which may lead to packet drop.
