I am trying to collect the data from the server through SNMP.
snmpwalk does not return back any essential data as a web interface does, but I need to fetch that kind of data via SNMP.
snmpwalk -c public -v 1 <ip> .

I would like to fetch the same set of parameter as available in web interface

Is this possible?
The dump you've provided as a result of snmpwalk command is just a snapshot of RFC1213 (mib-2) data. And yes your assumptions are correct: It is not the information you're interested in as it only contains the set of data about network interfaces and common system information (system group of MIB-II). You'll need to contact your vendor to get specific set of MIB files for this particular device. Usually the target MIB files are available on vendor's web site in Download area. The data you'd like to retrieve is usually located in private enterprise specific branch of MIB tree.
From what I see the Enterprise OID 1.3.6.1.4.1.11606 belongs to Pacific Broadband Networks (PBN).
Also I've found the definition for the root element of this MIB module:
PBN-ROOT DEFINITIONS ::= BEGIN
IMPORTS
enterprises
FROM RFC1155-SMI;
pbn OBJECT IDENTIFIER ::= { enterprises 11606 }

I created this code because I was not able to find any functional that accomplishes my requirement.
If you can reduce it will be better.
Just enter de prefix lenght from 1 to 32 and you will get the decimal mask.
This code help me with my scripts for cisco.
import math
#Netmask octets
octet1 = [0,0,0,0,0,0,0,0]
octet2 = [0,0,0,0,0,0,0,0]
octet3 = [0,0,0,0,0,0,0,0]
octet4 = [0,0,0,0,0,0,0,0]
#POW list
pow_list = [7,6,5,4,3,2,1,0]
#Introduce prefix lenght
mask = int(input("Introduce the prefix lenght: "))
#According to the number of bits we will change the array elements from 0 to 1
while mask >= 25 and mask <= 32:
octet4[mask-25] = 1
mask -= 1
while mask >= 17 and mask <= 24:
octet3[mask-17] = 1
mask -= 1
while mask >= 9 and mask <= 16:
octet2[mask-9] = 1
mask -= 1
while mask >= 1 and mask <= 8:
octet1[mask-1] = 1
mask -= 1
#Obtain the number of ones
ones1 = octet1.count(1)
ones2 = octet2.count(1)
ones3 = octet3.count(1)
ones4 = octet4.count(1)
#Summary and reuslt of each octet.
sum1 = 0
for i in range(0,ones1):
sum1 = sum1 + math.pow(2,pow_list[i])
sum1 = int(sum1)
sum2 = 0
for i in range(0,ones2):
sum2 = sum2 + math.pow(2,pow_list[i])
sum2 = int(sum2)
sum3 = 0
for i in range(0,ones3):
sum3 = sum3 + math.pow(2,pow_list[i])
sum3 = int(sum3)
sum4 = 0
for i in range(0,ones4):
sum4 = sum4 + math.pow(2,pow_list[i])
sum4 = int(sum4)
#Join the results with a "."
decimal_netmask = str(sum1) + "." + str(sum2) + "." + str(sum3) + "." + str(sum4)
#Result
print("Decimal netmask is: "+ decimal_netmask)
Result:
Introduce the prefix lenght: 23
Decimal netmask is: 255.255.254.0
As you are probably doing more than just converting CIDR to netmask, I recommend checking out the built-in library ipaddress
from ipaddress import ip_network
cidr = input("Introduce the prefix length: ")
decimal_netmask = str(ip_network(f'0.0.0.0/{cidr}').netmask)
You can simplify your code by computing the overall mask value as an integer using the formula:
mask = 2**32 - 2**(32-prefix_length)
Then you can compute the 4 8-bit parts of the mask (by shifting and masking), appending the results to a list and then finally joining each element of the list with .:
def decimal_netmask(prefix_length):
mask = 2**32 - 2**(32-prefix_length)
octets = []
for _ in range(4):
octets.append(str(mask & 255))
mask >>= 8
return '.'.join(reversed(octets))
for pl in range(33):
print(f'{pl:3d}\t{decimal_netmask(pl)}')
Output:
0 0.0.0.0
1 128.0.0.0

I am trying to simulate the effect of aging in the back-to-back inverters (SRAM PUF). I want to see the starting up of the back-to-back inverter's start-up voltage with transistor aging effect, wherein in one case the output initial from the 2 inverters is 1 0 and in another case, the output case will be 0 1.
How to do this in hspice. I know a little about the MOSRA test, but I am not sure how to use that to get the intended aging effect.
I have written a back-to-back inverter hspice netlist. but the output is always same with the simulation. How to flip the output with aging simulation. Any help is appreciated.

ndf.loc[i,'Entry'] = ndf.loc[i,'Revals']
elif (element == 0):
ndf.loc[i,'Entry'] = ndf.loc[i - 1,'Entry']
else:
ndf.loc[i,'Entry'] = ndf.loc[i,'Revals']
This will solve the problem but when assigning, the index should be same. So because of the index thing you might not be able to get the expected result.
Do not chain indexes like ndf.iloc[i]['Entry'] when trying to assign something. See why does that not work.
That said, your code can be rewrite as:
ndf['Entry'] = ndf['Revals'].where(signals_diff != 0).ffill()
Output:
Signals Revals Entry
0 1 101 101.0
1 1 102 101.0
2 1 105 101.0
3 1 104 101.0
4 1 105 101.0
5 0 106 106.0
6 0 107 106.0
7 0 108 106.0
8 0 109 106.0
9 0 109 106.0
Let us keep using the index position slice with get_indexer
for i,element in enumerate(signals_diff):
if (i==0):
ndf.iloc[i,ndf.columns.get_indexer(['Entry'])] = ndf.iloc[i,ndf.columns.get_indexer(['Revals'])]
elif (element == 0):
ndf.iloc[i,ndf.columns.get_indexer(['Entry'])] = ndf.iloc[i - 1,ndf.columns.get_indexer(['Entry'])]
else:
ndf.iloc[i,ndf.columns.get_indexer(['Entry'])] = ndf.iloc[i,ndf.columns.get_indexer(['Revals'])]
I'm trying to find and print the minimum value for n that satisfies ca >= cb:
ap = 80000
bp = 200000
at = 1.03
bt = 1.015
n = 1
ca = ap*at*n
cb = bp*bt*n
while cb > ca:
n = n + 1
print(n)
The code just runs and prints n + 1 indefinitely, though. What is the correct approach to this problem?
ap = 80000
bp = 200000
at = 1.03
bt = 1.015
n = 1
ca = ap*at*n
cb = bp*bt*n
while cb > ca:
n += 1
ca = ap*at*n
cb = bp*bt*n
This won't converge though.
The settings i have applied in my sysctl.conf are not working. Not on reboot or after applying it using sysctl -p
