I am currently using python 2.7 and will need to ping windows and linux.
I want to create a function that will return the IP address from a ping within a python script. I currently have this function
def ping(host):
"""
Returns True if host responds to a ping request
"""
import subprocess, platform
# Ping parameters as function of OS
ping_str = "-n 1" if platform.system().lower()=="windows" else "-c 1"
args = "ping " + " " + ping_str + " " + host
need_sh = False if platform.system().lower()=="windows" else True
# Ping
return subprocess.call(args, shell=need_sh) == 0
Right now it just returns true or false but is there a way I can run ping(google.com) and have it return 216.58.217.206. I have a list of servers and IPs and I need to make sure that the IP addresses match the FQDN.
You can use the socket to get the IP of the host.
import socket
print(socket.gethostbyname('www.example.com'))
Not sure how no-one has tried this method yet (for windows anyways)!
Use a WMI query of W32_PingStatus
With this method we return an object full of goodies
import wmi
# new WMI object
c = wmi.WMI()
# here is where the ping actually is triggered
x = c.Win32_PingStatus(Address='google.com')
# how big is this thing? - 1 element
print 'length x: ' ,len(x)
#lets look at the object 'WMI Object:\n'
print x
#print out the whole returned object
# only x[0] element has values in it
print '\nPrint Whole Object - can directly reference the field names:\n'
for i in x:
print i
#just a single field in the object - Method 1
print 'Method 1 ( i is actually x[0] ) :'
for i in x:
print 'Response:\t', i.ResponseTime, 'ms'
print 'TTL:\t', i.TimeToLive
#or better yet directly access the field you want
print '\npinged ', x[0].ProtocolAddress, ' and got reply in ', x[0].ResponseTime, 'ms'

When I filter the packets using this filter in wireshark:
wlan.sa == 04.b1.67.14.bd.64
All goes perfect.
However, I'm trying to do it with the following python script using scapy, but it never filter by the source mac:
from scapy.all import *
from datetime import datetime
import traceback
# import MySQLdb
def getAverageSSI():
global ssiFinal
return ssiFinal
def setParams():
global window
global timestamp
global SSID
global datetime
global iterator1
window = 1
timestamp = datetime.now()
SSID='DefaultName'
iterator1 = 0
global ssiArray
ssiArray = []
def myPacketHandler(pkt) :
global SSID
global timestamp
global iterator1
global ssiArray
try :
if pkt.haslayer(Dot11) :
ssiNew = -(256-ord(pkt.notdecoded[-4:-3]))
ssiArray.append(ssiNew)
diffT=(datetime.now()-timestamp).seconds
if diffT>window:
print 'With MAC dst = %s with SSI Power= %s' %(pkt.addr1, sum(ssiArray)/len(ssiArray))
print ssiArray
ssiArray = []
timestamp=datetime.now()
except Exception as e:
print 'Exception'
print e
traceback.print_exc()
sys.exit(0)
setParams()
try:
sniff(iface="wlan1", filter="ether src 04:b1:67:14:bd:64", prn = myPacketHandler, store=0)
except Exception as e:
print e
print "Sniff AP1 Off"
I have also tried to remove the filter in sniff, and put an if like the following:
if pkt.addr1 == '04:b1:67:14:bd:64' : # mac xiaomi mi a1
# SSID = pkt.info;
ssiNew = -(256-ord(pkt.notdecoded[-4:-3]))
ssiArray.append(ssiNew)
diffT=(datetime.now()-timestamp).seconds
if diffT>window:
# query = "START TRANSACTION;"
# queryBack=cur.execute(query)
# query = "INSERT INTO RSSI VALUES(%d,\"AP1\",%d);"%(iterator1,ssiNew)
# queryBack = cur.execute(query)
print 'MAC = %s with SSI Power= %s' %(pkt.addr1, sum(ssiArray)/len(ssiArray))
ssiArray = []
# Conexion.commit()
# iterator1+=1
timestamp=datetime.now()
But it is only filtering by destination mac.
Do you know how to properly filter by mac like in the following wireshark image? (it needs to be exactly the same behaviour than in the wireshark filter):
Your second method should be working well, if you used addr2 instead of addr1
Here is how it works in 802.11 (yes it’s really messy)
Also, you should update to the github scapy version, which has support for RSSI directly (so you don’t have to parse notdecoded)
See https://github.com/secdev/scapy/archive/master.zip
I've tried to create a little app that plays a sound when you lose connectivity for an extended period and plays another when the connection is established. Useful for wireless connections.
I'm still new to Python :) trying little projects to improve my knowledge. If you do answer I will be very grateful if you could include any information about how to use subprocess.
I've defined the subprocess but I'm not sure how to word my if statement so it loops from one function to the other. IE Function 1 = IF ping loss > 15 pings play sound and move on to function 2... If function 2 ping success > 15 pings play sound and move back to function 1. So on.
I've yet to wrap the program in a loop, at this point I'm just trying to get the ping to work with the if statement.
So right now the application just continuously loop pings.
import os
import subprocess
import winsound
import time
def NetFail():
winsound.Beep(2000 , 180), winsound.Beep(1400 , 180)
def NetSucc():
winsound.Beep(1400 , 250), winsound.Beep(2000 , 250),
ips=[]
n = 1
NetSuccess = 10
NetFailure = 10
PinSuc = 0
PinFail = 0
x = '8.8.8.8'
ips.append(x)
for ping in range(0,n):
ipd=ips[ping]
def PingFailure():
while PinFail < NetSuccess:
res = subprocess.call(['ping', '-n', '10', ipd])
if ipd in str(res):
PingSuccess()
else:
print ("ping to", ipd, "failed!"), NetFail()
def PingSuccess():
while PinFail < NetFailure: # This needs to be cleaned up so it doesn't interfere with the other function
res = subprocess.call(['ping', '-n', '10', ipd])
if ipd in str(res):
PingFail()
else:
print ("ping to", ipd, "successful!"), NetSucc()
As you use the command ping -n 10 ip, I assume that you are using a Windows system, as on Linux (or other Unix-like) it would be ping -c 10 ip.
Unfortunately, on Windows ping always return 0, so you cannot use the return value to know whether peer was reached. And even the output is not very clear...
So you should:
run in a cmd console the command ping -n 1 ip with an accessible and inaccessible ip, note the output and identify the differences. On my (french) system, it writes Impossible, I suppose that you should get Unable or the equivalent in your locale
start the ping from Python with subprocess.Popen redirecting the output to a pipe
get the output (and error output) from the command with communicate
search for the Unable word in output.
Code could be like:
errWord = 'Unable' # replace with what your locale defines...
p = subprocess.Popen([ 'ping', '-n', '1', ipd],
stdout = subprocess.PIPE, stderr=subprocess.PIPE)
out, err = p.communicate()
if errWord in out:
# process network disconnected
else:
# process network connected
Alternatively, you could search pypi for a pure Python implementation of ping such as py-ping ...
Anyway, I would not use two functions in flip-flop because it will be harder if you later wanted to test connectivity to multiple IPs. I would rather use an class
class IP(object):
UNABLE = "Unable" # word indicating unreachable host
MAX = 15 # number of success/failure to record new state
def __init__(self, ip, failfunc, succfunc, initial = True):
self.ip = ip
self.failfunc = failfunc # to warn of a disconnection
self.succfunc = succfunc # to warn of a connection
self.connected = initial # start by default in connected state
self.curr = 0 # number of successive alternate states
def test(self):
p = subprocess.Popen([ 'ping', '-n', '1', self.ip],
stdout = subprocess.PIPE, stderr=subprocess.PIPE)
out, err = p.communicate()
if self.UNABLE in out:
if self.connected:
self.curr += 1
else:
self.curr = 0 # reset count
else:
if not self.connected:
self.curr += 1
else:
self.curr = 0 # reset count
if self.curr >= self.MAX: # state has changed
self.connected = not self.connected
self.curr = 0
if self.connected: # warn for new state
self.succfunc(self)
else:
self.failfunc(self)
Then you can iterate over a list of IP objects, repeatedly calling ip.test(), and you will be warned for state changes
Not quite sure, what you want to achieve, but your if statement has to be part of the while loop if you want it to be executed each time ping is called via subprocess is called.
Also:
Here is the documentation for subprocess: https://docs.python.org/3/library/subprocess.html
For viewing the output of a process you have to call it via subprocess.call_output:
ls_output = subprocess.check_output(['ls'])

I was making a site component scanner with Python. Unfortunately, something goes wrong when I added another value to my script. This is my script:
#!/usr/bin/python
import sys
import urllib2

def main(path):
print "[+] Testing:",host.split("/",1)[1]+path
try:
h = httplib.HTTP(host.split("/",1)[0])
h.putrequest("HEAD", "/"+host.split("/",1)[1]+path)

print "Example: python jx.py www.site.com/\n"
sys.exit(1)
host = sys.argv[1].replace("http://","").rsplit("/",1)[0]
if host[-1] != "/":
host = host+"/"
print "\n[+] Site:",host
print "[+] Loaded:",len(coms)
print "\n[+] Scanning Components\n"
for com,nme,expl in coms.items():
resp,reason,server = main(com)
if resp not in BAD_RESP:
print ""
print G+"\t[+] Result:",resp, reason
print G+"\t[+] Com:",nme
print G+"\t[+] Link:",expl
print W
else:
print ""
print R+"\t[-] Result:",resp, reason
print W
print "\n[-] Done\n"
And this is the error message that comes up:
Traceback (most recent call last):
File "jscan.py", line 69, in <module>
for com,nme,expl in xpls.items():
ValueError: need more than 2 values to unpack
I already tried changing the 2 value into 3 or 1, but it doesn't seem to work.
xpls.items returns a tuple of two items, you're trying to unpack it into three. You initialize the dict yourself with two pairs of key:value:
coms = { "index.php?option=com_artforms" : "com_artforms" + "link1","index.php?option=com_fabrik" : "com_fabrik" + "ink"}
besides, the traceback seems to be from another script - the dict is called xpls there, and coms in the code you posted...
you can try
for (xpl, poc) in xpls.items():
...
...
because dict.items will return you tuple with 2 values.
You have all the information you need. As with any bug, the best place to start is the traceback. Let's:
for com,poc,expl in xpls.items():
ValueError: need more than 2 values to unpack
Python throws ValueError when a given object is of correct type but has an incorrect value. In this case, this tells us that xpls.items is an iterable an thus can be unpacked, but the attempt failed.
The description of the exception narrows down the problem: xpls has 2 items, but more were required. By looking at the quoted line, we can see that "more" is 3.
In short: xpls was supposed to have 3 items, but has 2.
Note that I never read the rest of the code. Debugging this was possible using only those 2 lines.
Learning to read tracebacks is vital. When you encounter an error such as this one again, devote at least 10 minutes to try to work with this information. You'll be repayed tenfold for your effort.
As already mentioned, dict.items() returns a tuple with two values. If you use a list of strings as dictionary values instead of a string, which should be split anyways afterwards, you can go with this syntax:
coms = { "index.php?option=com_artforms" : ["com_artforms", "link1"],
"index.php?option=com_fabrik" : ["com_fabrik", "ink"]}
for com, (name, expl) in coms.items():
print com, name, expl
>>> index.php?option=com_artforms com_artforms link1
>>> index.php?option=com_fabrik com_fabrik ink
I have created a simple RAW socket based packet sniffer. But when I run it, it rarely captures up a packet. First I created this to capture packets in 1 second time intervals, but seeing no packets are captured I commented that line. I was connected to internet and a lot of http traffic are going here and there, but I could not capture a one. Is there a problem in this in the code where I created the socket? Please someone give me a solution. I am fairly new to python programming and could not understand how to solve this.
import socket, binascii, struct
import time
sock = socket.socket(socket.PF_PACKET, socket.SOCK_RAW, socket.htons(0x800))
print "Waiting.."
pkt = sock.recv(2048)
print "received"
def processEth(data):
#some code to process source mac and dest. mac
return [smac, dmac]
def processIP(data):
sip = str(binascii.hexlify(data[1]))
dip = str(binascii.hexlify(data[2]))
return [sip, dip]
def processTCP(data):
sport = str(data[0])
dport = str(data[1])
return [sport, dport]
while len(pkt) > 0 :
if(len(pkt)) > 54:
pkt = sock.recv(2048)
ethHeader = pkt[0][0:14]
ipHeader = pkt[0][14:34]
tcpHeader = pkt[0][34:54]
ethH = struct.unpack("!6s6s2s",ethHeader)
ethdata = processEth(ethH)
ipH = struct.unpack("!12s4s4s",ipHeader)
ipdata = processIP(ipH)
tcpH = struct.unpack("!HH16", tcpHeader)
tcpdata = processTCP(tcpH)
print "S.mac "+ethdata[0]+" D.mac "+ethdata[1]+" from: "+ipdata[0]+":"+tcpdata[0]+" to: "+ipdata[1]+":"+tcpdata[1]
#time.sleep(1);
else:
continue
If you showed all the code, you are running into an endless loop.
Whenever a paket is coming in which has not a length greater then 54 bytes, you end up reading the same packet all the time.
Additionally, socket.recv() returns a string/byte sequence; your approach of accessing the data is wrong. pkt[0] returns a string with length 1; pkt[0][x:y] will not return something useful.
I am not familiar with using sockets, but with some changes I got output that might look similar to what you intended (there is something missing in processEth() I think...).

I'm having some issues with the EC2 bit of Boto (Boto v2.8.0, Python v2.6.7).
The first command returns a list of S3 Buckets - all good! The second command to get a list of EC2 instances blows up with a 403 with "Query-string authentication requires the Signature, Expires and AWSAccessKeyId parameters"
s3_conn = S3Connection(AWSAccessKeyId, AWSSecretKey)
print s3_conn.get_all_buckets()
ec2_conn = EC2Connection(AWSAccessKeyId, AWSSecretKey)
print ec2_conn.get_all_instances()
Also, my credentials are all good (Full admin) - I tested them using the Ruby aws-sdk, both EC2 and S3 work fine.
I also noticed that the host attribute in the ec2_conn object is s3-eu-west-1.amazonaws.com, "s3"...? Surely thats wrong? I've tried retro fixing it to the correct endpoint but no luck.
Any help would be great appreciate
Thanks
Here's some working code I use to list all my instances across potentially multiple regions.
Its doing a lot more than you need, but maybe you can pare it down to what you want.
#!/usr/bin/python
import boto
import boto.ec2
import sys
class ansi_color:
red = '\033[31m'
green = '\033[32m'
reset = '\033[0m'
grey = '\033[1;30m'
def name(i):
if 'Name' in i.tags:
n = i.tags['Name']
else:
n = '???'
n = n.ljust(16)[:16]
if i.state == 'running':
n = ansi_color.green + n + ansi_color.reset
else:
n = ansi_color.red + n + ansi_color.reset
return n
def pub_dns( i ):
return i.public_dns_name.rjust(43)
def pri_dns( i ):
return i.private_dns_name.rjust(43)
def print_instance( i ):
print ' ' + name(i) + '| ' + pub_dns(i) + ' ' + pri_dns(i)
regions = sys.argv[1:]
if len(regions)==0:
regions=['us-east-1']
if len(regions)==1 and regions[0]=="all":
rr = boto.ec2.regions()
else:
rr = [ boto.ec2.get_region(x) for x in regions ]
for reg in rr:
print "========"
print reg.name
print "========"
conn = reg.connect()
reservations = conn.get_all_instances()
for r in reservations:
# print ansi_color.grey + str(r) + ansi_color.reset
for i in r.instances:
print_instance(i)
There is the connect_to_region command:
import boto.ec2
connection = boto.ec2.connect_to_region('eu-west-1', aws_access_key_id=AWSAccessKeyId,
aws_secret_access_key=AWSSecretKey)
The Boto tutorial gives another way. That method would basically work like this:
import boto.ec2
for region in boto.ec2.regions():
if region.name == 'my-favorite-region':
connection = region.connect()
break
This has not been working on older versions of Boto.
Do you have your IAM credentials in order? The given access key should have rights for EC2. If you're not sure, you can add the policy AmazonEC2FullAccess to test, and later tune this down.
