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.
