Hello!
I want to get route tables from Cisco routers in the network. What i
have:
import re
from pysnmp.entity.rfc3413.oneliner import cmdgen
s = r'(%s)' % ('(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.)\
{3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)')
pattern = re.compile(s)
file = 'routers.txt'
s = open(file).read()
i = 0
router_list = []
while True:
match = pattern.search(s, i)
if match:
router_list.append(match.group(1))
i = match.end() + 1
else:
break
class router:
def __init__(self, who):
self.name = who
routetable = {}
router1 = router(router_list[0])
cmdGen = cmdgen.CommandGenerator()
errorIndication, errorStatus, errorIndex, varBindTable =
cmdGen.nextCmd(
cmdgen.CommunityData('test-agent', public, 0),
cmdgen.UdpTransportTarget((router1.name, 161)),
(1,3,6,1,2,1,4,21,1,1))
if errorIndication:
print errorIndication
else:
if errorStatus:
print '%s at %s\n' %
(errorStatus.prettyPrint(),varBindTable[-1][int(errorIndex)-1])
else:
for varBindTableRow in varBindTable:
for oid, val in varBindTableRow:
print varBindTableRow
Result:
Code: Select all
[(ObjectName('1.3.6.1.2.1.4.21.1.1.0.0.0.0'), IpAddress('0.0.0.0'))]
[(ObjectName('1.3.6.1.2.1.4.21.1.1.10.9.0.0'), IpAddress('10.9.0.0'))]
[(ObjectName('1.3.6.1.2.1.4.21.1.1.192.168.1.0'),
IpAddress('192.168.1.0'))]
How can i get IpAddress values from this list and put they in the
dictionary? Or may be there is much better solution?
