Latest commit d3a3608 1 @vincentbernat snmp: fix retrieving of OID with PySNMP 4.3+
Starting with PySNMP 4.3, an OID is wrapped into an ObjectIdentity which
is some kind of facade to make it act more like a Python
object. However, it doesn't get a prettyOut function so we get some
exception. Since this ObjectIdentity object doesn't exist with PySNMP
4.2, we try to extract the OID with getOID() but ignore any error and
assume that we already have an ObjectIdentifier object.

This should be compatible with both 4.2 and 4.3.

Fix #47

Interactive SNMP tool.

Snimpy is a Python-based tool providing a simple interface to build SNMP query. Here is a very simplistic example that allows us to display the routing table of a given host:

load("IP-FORWARD-MIB")
m=M("localhost", "public", 2)
routes = m.ipCidrRouteNextHop
for x in routes:
    net, netmask, tos, src = x
    print("%15s/%-15s via %-15s src %-15s" % (net, netmask, routes[x], src))

You can either use Snimpy interactively throught its console (derived from Python own console or from IPython if available) or write Snimpy scripts which are just Python scripts with some global variables available.

Snimpy requires libsmi_ to work correctly. See the documentation for more information.

Features

Snimpy is aimed at being the more Pythonic possible. You should forget that you are doing SNMP requests. Snimpy will rely on MIB to hide SNMP details. Here are some "features":

  • MIB parser based on libsmi (through CFFI)
  • SNMP requests are handled by PySNMP (SNMPv1, SNMPv2 and SNMPv3 support)
  • scalars are just attributes of your session object
  • columns are like a Python dictionary and made available as an attribute
  • getting an attribute is like issuing a GET method
  • setting an attribute is like issuing a SET method
  • iterating over a table is like using GETNEXT
  • when something goes wrong, you get an exception
Something went wrong with that request. Please try again.
