@dusty oyster idk i dont think so

does anyone have any good resources for two way real-time communications between a controller and robot?
@cerulean tusk 0MQ might be good for that
assuming that the "robot" and the "controller" are python processes that are on the same network
if you mean a real robot, then I have no idea
cerulean tusk
@lavish rock yeah real robot. (A drone)
lavish rock
well actually, if the robot and the controller are talking over the same sort of TCP/IP network that I use every day to use the web, then I stand by 0MQ
probably the "pubsub" style

I've got a question regarding best practices for implementing a program with a network dependency. This "api"/program connects to a webhook, local db, someone else's api, and a collection of scripts for interfacing with a lan connected controller.
The controller has no implemented security and relies exclusively on obscurity and network isolation for security. With that in mind how do I expose my api without risking/exposing the controller? Is there a secure way to host the api online and still have it securely execute the scripts on the lan? I would actually like to host the api on the same network as the controller, but I don't know how to keep the controller safe and expose the api?
Any advice is appreciated.
compact mist
@crisp thistle Know very little about security, but if you keep it on LAN and ensure it isn't exposed then that's the safest option. To ensure it isn't exposed host it on 0.0.0.0 (i.e. the LAN address) rather than your external IP and also remove any unnecessary port forwarding on the router and enable all of the security measures.
crisp thistle
The webhook requires access to my hosted api. I also don't fully understand what you mean by.
To ensure it isn't exposed host it on 0.0.0.0
So presumably I would need to portforward and provide the webhook with my public IP.
compact mist
@crisp thistle I think I misunderstood the situation you described. How about changing the settings on the router such that the only IP allowed to connect to the port is your IP?
crisp thistle
@compact mist is there risk associated with exposing the machine running the server?
compact mist
Of course.
Mitigation is the only thing you can do.
So minimal number of open ports
Restrictive rules, etc.
crisp thistle
Besides firewall settings and a token system for the api is there anything else I can do to mitigate risk?
compact mist
As I said, disallowing all IPs except yours.
crisp thistle
Externally I don't have control over the webhooks ip
compact mist
I believe that can be done at the router level.
Or do you not have access to the router?
crisp thistle
The web hook is wild apricot. They're the webhook host and external api I'm interfacing with.
My application takes their webhook and checks if a flag exists and updates their api/ runs an associated script
compact mist
Right so a VPS?
crisp thistle
Uhh, I don't know?
compact mist
It's a (Linux?) server in the cloud right?
crisp thistle
Presumably. It's more like a cms. I don't have access to anything past a WordPress like editor and the api isn't hosted under our domain
It's accessed via api.wildapricot.com our data is accessed via an account id
compact mist
Right.
In that case, I'm sure they've already implemented a lot of security features.
This seems more like domain securing.
crisp thistle
My concern is not with their platform's security. Rather my api's hosts security
compact mist
I know nothing about that aspect of security.
crisp thistle
Neither do i
compact mist
Surely the API's host is wild apricot?
crisp thistle
Yeah, but the scripts are running on my server.
Scripts are located here
They talk to this box
The box will open the door if you tell it too. It doesn't ask questions. It just spits out yes sir. So if the network is compromised the door is open to anyone with wireshark.
If I expose an api do I need to be concerned about the door popping open randomly?
crisp thistle
Pfsense for router/firewall, server w/ scripts is running Linux in a vm
crisp thistle
That's ok, I appreciate the help. Is securing the server enough to secure the network? Assuming pfsense is configured correctly?
compact mist
Both are best, if possible.

Does the router send packets to another router in another network to be able to send the require data to the desired address ?

Im trying to send a GET request for a website and everything is working fine for me locally but when I deploy to AWS I get 403'd every single time. Im using an HTTTP proxy to try get pass this but somehow the site can still work out when im sending the request from AWS. Any ideas how they might be doing this?
Originally I thought the site might be using the X-Forwarded-For header to determine where the request is coming from but my proxy also spoofs that header so i think its something else.
oak spoke
I don't know if this might help, @patent wharf : https://aws.amazon.com/premiumsupport/knowledge-center/s3-403-forbidden-error/

The problem isnt on the AWS side. Im trying to get a site thats hosted by Akamai which is known to be blocking the IP ranges published by AWS
Im just trying to work out how theyre able to identify that the request is coming from am AWS instance despite being behind a proxy

hey guys, i have a question i tried googling for. it's worded weirdly. "Why do you need the IP address of a DNS server?"
snow tulip
so you can send DNS requests to it.
ember ledge
thankyou! ill google what a dns request is now, youve helped heaps :). cheers bro
snow tulip
you send a DNS request to a DNS server (lets say 8.8.8.8) and ask it "hey, i want to get to www.google.com, how do i get there?" and it'll send you a reply with what IP address is associated with www.google.com so your computer knows what web server to communicate with.
all the diagrams on google are shit, rofl
so i did something way worse
ember ledge
@snow tulip why not just ask another dns server how to get to the dns server
it's dns servers all the way down

we've been lied to all along, there are no webservers

So I'm pretty bad at networking in general and I'm trying to figure out if I can do this/how I can do this.
I'm trying to monitor a UDP port on a wifi network that I'm connected to. It's usually not a problem because I'm only connected to one network. But I'm currently connected to a wifi network and an ethernet network and I don't know how to bind the socket to the one network + port. (If that's even the correct way of thinking about it)
swift dagger
are you the admin of the wifi network itself?
@solid bluff are you the admin of said wifi network?
solid bluff
Yes, I have admin control of both networks
swift dagger
is this like a home wifi router?
solid bluff
For now it's a dinky little LinkSys, eventually it'll be a full-up proper Nighthawk-like router
But it's a simple network with just a router, not even connected to the internet
swift dagger
i'm not sure if a dinky linksys could do it, but a couple things to try.... enable syslog/logging, then you could do an access control list / restriction on the UDP port number in question. You might have the option to send it to a log
and use the router's UI to output the log
otherwise, if you are just trying to see if that UDP port is hitting your PC or device, you could use wireshark, or another linux based app to do a packet capture. you could filter the pcap on the UPD port while capturing to limit the packets written to the pcap
solid bluff
Alright, I'll do that~ Thanks
merry halo
can you guys help me with a ZMQ problem?
can I ask here
I'm using a PUB/SUB design pattern, problem is my client does not ALWAYS recieve all the msgs only the first ones
The server loops through a list of objects, the data on those objects changes in real time. Every millisecond the server publishes all of the new data of those objects.
i.e. ['Carrot', 'Banana', 'Mango', 'Eggplant']
The Client can subscribe to specific objects via their name. self.sub_socket.setsockopt_string(zmq.SUBSCRIBE, 'Carrot')
On a thread the client polls these data in realtime as well
while True:
sockets = dict(self.poller.poll(poll_timeout))
if self.sub_socket in sockets and sockets[self.sub_socket] == zmq.POLLIN:
msg = self.sub_socket.recv_string(zmq.DONTWAIT)
// do something with the msg...
The problem is when I subscribe to multiple objects let's say, Carrot, Eggplant & Banana. I only
recieve the changes from Carrot, sometimes Banana, and so rare on Eggplant. I think this is because from the order of looping of the server, like maybe when the client polls, receives Carrot, process the data, then polls again but the server is already done with the publishing through the list and just publishing Carrot again then client polls recieves just Carrot because of that.
So I thought of creating individual sockets for each subscription? Is that a solution? I'm pretty new with ZMQ, would love some help here thanks!

Hello!
I need to automate some string searches on a particular web site. At every search, it generates a .php page containing the data I want to download. I haven't done much scraping before so am unsure of where to start. The search string is not part of the page's address.
Ideas? 🙂
snow tulip
you could use the requests library to send a GET request and then parse the data you get back
requests + beautiful soup should do the trick
fathom bear
@snow tulip Is a GET request equivalent to entering a string into the site's search field and hit enter?
snow tulip
well when you enter a search string, does the new URL you're directed to take you to like uhhh
http://somesite.com/?q=searchquery
?
snow tulip
you could probably look at the network traffic and figure out how it's sending the request
or you could be lazy and just automate the action with a browser driver like Selenium
fathom bear
@snow tulip Would Selenium be much slower, or is the bottleneck probably the page's loading time? (it's a bit slow, takes a few seconds).
snow tulip
selenium would be slower as it'd have to drive the browser
fathom bear
Hmm
Well OK, I'll try with requests and beautifulsoup first, then.
@snow tulip I realized it's actually three php pages generated in total, of which only the last one contains the data I want. It goes like this:
- Enter search string, hit enter
- Click a button in generated php page # 1
- php page #2 loads
- php page #3 loads
- Get data
Is this possible with requests and beautifulsoup?
snow tulip
Couldn't possibly say without trying or looking at it myself
But if it were me I'd be lazy and just go the selenium route
Then again if I've got a hammer everything looks like a nail
fathom bear
Selenium sounds a bit simpler for a rookie to get going, I must say. I don't have all the time in the world for this so perhaps I'll try that first. Thanks for your help and thoughts m8!

Anyone know what does “scapy contextmanagersubprocess” do? And can anyone explain it to me?
worldly lodge
@fresh gull Haven't used scapy but the documentation for ContextManagerSubprocess is here: https://scapy.readthedocs.io/en/latest/api/scapy.utils.html#scapy.utils.ContextManagerSubprocess
Looks like its a context manager that stops you from crashing if you use subprocess to run a command or program that's not available or couldn't be found

Connecting to the EC2 instance via rdp client works perfectly
When I run both these scripts on local host they seem to work fine.
But in case of AWS EC2 Instance, it does not.
Where did I go wrong?

on the server, i'd try binding to 0.0.0.0 instead of host
you're sure you're using a "security group" that allows all inbound ports?

Yes

@ember ledge theres no inet_addr() in python

It need it in uint32 format

give me an example of you using it
oh nvm it does
b'2224'
input, code, and output
that's not what I need
printf("%lu\n", inet_addr("50.50.50.52"));
I am very sure I do know what inet_addr does
@ember ledge I tried inet_pton and it sort of gives what I am looking for but in the wrong endianness
yes... you are casting it as a long...
that's exactly what I am looking for
give me a sec
ignore the ctypes import
give me a second

So I just stumbled upon the concept of socket programming (I am new to python). Although I think i got the basics of the concept, I am having trouble figuring out when to use it compared to a web server like a flask application. For instance I just started on a little home automation project. Initially I was going to use flask to build a simple API, which talks back and forth with devices, but now I am starting to wonder if socket programming is the way forward. When do you use what?
pulsar zephyr
atomic warren
check the pins
narrow oak
@ebon crescent
Use flask if you care about having your API being user-friendly and perhaps used by several people. You would also need to code more if you decide to go with a web based solution as you would need to somehow transfer the data from the website to the back-end flask (dependent on how you build your project), which might require some JavaScript. Sockets on the other side are low-level and quite efficient. If you want some simple communication between two or more devices then sockets is probably the easiest solution, though it might not be so user-friendly if you decide to go with a non-web-based solution. For longer strings and data / images then sockets is probably the technology you would chose.

if you were trying to create a "sub" network with the 2nd router you'd need one with a WAN RJ45 port
as xx says, the router may support a WiFi Bridge mode.

Hi i am running a python program(app.py) which uses socket library to port scan, also after the port scanning is done, I am calling another python file, screenshot.py which uses selenium but when I run app.py the error occurs (Can not connect to the Service chromedriver) but running the screenshot.py individually doesn't
as in running both socket and selenium one after the other causes the error, but running the selenium program individually the program works fine.
also, I am using a reverse_proxy via local host.

Hi guys, Ive created my own load balancer and I want to be able to differentiate between requests that are using the load balancer as a proxy and requests that are just attempting to GET the server.
from the server side how would I be able to differentiate between:

curl http://loadbalancer.com/
In the case that someone just GETs the page instead of using it as a load balancer i want to serve some HTML

Hey @willow glade!

guys, LAN is under peer to peer or client server network, or both
vapid dock
lan is land area network it can act like client server network if their is a server idk about peer to peer
cunning nimbus
OKOK, THX
wide sail
Peer to peer and client/server is application level structures. LAN is a network layer concept so it is a bit like comparing apples and oranges.
Client/server essentially only means one of the applications is client, the other is server. Client sends the server requests and the server responds.
Peer to peer means that both applications can be "server" or "client" depending on requirements. They can also switch the roles around. They are equal.
In short applications within a LAN can be configured to act both as client/server or peer to peer.

Could anyone quickly clear up what a post request does? I've seen curl -X POST <url>, and that is supposed to create a new "resource" on the server. But, what's in the new resource?
An example might also be useful :D
ember ledge
it doesnt "do" anything unless the server says to
but conventionally, post is creating a resource
mayhaps this will help explain it?
ember ledge
POST just tells the server to expect some data in the request body.
An example GET request (which is sent to the server):
GET /index.php HTTP/1.1
Host: mysite.com
An example POST request:
POST /form.php HTTP/1.1
Host: mysite.com
value1=somedata&value2=otherdata
you could also include stuff in a GET request body, but by convention browsers don't do this so servers usually discard any data in a GET request
for get requests, the data is moved to the URL instead
example:
GET /form.php?value1=somedata&value2=otherdata HTTP/1.1
Host: mysite.com

I hope this channel is free. I got a question.
I have a data cap on my internet connection. I feel like my ISP's portal is overestimating my data usage. So I decided to measure my data usage on my own. We (family) use 4 devices. (2 phones, 2 laptops ) It's kinda hard to install seperate meters like Glasswire or vnstat and add up all to find total usage. I have a openvpn server (self hosted). So I'm thinking of setting up it to measure data usage. (Then use VPN on all devices.) Will this work as I want. I mean will it measure my data usage correctly.
will it be disturbed by extra data usage of VPN service for encryption etc etc. ?
my router's firmware doesn't have a bandwith meter and im not confortable with installing a custom firmware. Also I don't have resources to setup pfsense or something like that :/
rigid patrol
Encryption increases data usage
nova cedar
@rigid patrol how much will it increase. do you have any idea ?
rigid patrol
It varies of course, but 15% wouldn't surprise me
rigid patrol
Not without additional hardware being involved. Cable/DSL modems often have bandwidth usage metrics though
nova cedar
my router is a ISP issued one (their own firmware). there is a statistic tab. (im not sure how to read it.) :/

Hello all, I want to run linux command for capturing traffic using tcpdump. For example the command i want tran is "sudo tcpdump -nnli any -tttt 'tcp' -G 1 | awk '{print $1,$2,$4,$22}' any good python module , i have tried with subprocess and could not pass the linux pipe command.
shy pebble
you would probably have to run bash sudo tcpdump -nnli any -tttt 'tcp' -G 1 | awk '{print $1,$2,$4,$22} I think, but it would probably be easier to find some python library that can do similar behavior
real cedar
i can run in linux termainl, but i am looking python library that can do it
process2 = subprocess.Popen("|", "awk", '{print $1,$2,$4,$22}' ", stdout=subprocess.PIPE)
it sounds like you want to line buffer the output
real cedar
the "-l" in the command is used for line buffer out put, do you mean for the subprocess call?
snow tulip
so i can get real time read by doing something like uhhh
import subprocess
proc = subprocess.Popen(('sudo', 'tcpdump, '-l'), stdout=subprocess.PIPE
for line in iter(proc.stdout.readline, b''):
print(line.rstrip())```and that gives me a live output of tcpdump
oops, missed a bracket
snow tulip
np 👌

@snow tulip it is throwing an error File "app.py", line 3 proc = subprocess.Popen(('sudo', 'tcpdump, '-l'), stdout=subprocess.PIPE) ^ SyntaxError: EOL while scanning string literal

hey i double typo'd and didn't notice

gotta keep em on their toes ¬_¬
and actually now thinking about it i wouldn't bother to use awk to trim the tcpdump output anyway

how would i filter out on the fly , because the tcpdump is dumping huge data

The request has been fulfilled and resulted in a new resource being created. The newly created resource can be referenced by the URI(s) returned in the entity of the response, with the most specific URI for the resource given by a Location header field. The response SHOULD include an entity containing a list of resource characteristics and location(s) from which the user or user agent can choose the one most appropriate. The entity format is specified by the media type given in the Content-Type header field. The origin server MUST create the resource before returning the 201 status code. If the action cannot be carried out immediately, the server SHOULD respond with 202 (Accepted) response instead.A 201 response MAY contain an ETag response header field indicating the current value of the entity tag for the requested variant just created, see section 14.19.

Do you have Python installed and added to your path
Open a command prompt and navigated to your folder where the file is. Then python file.py should do the work.

"10.10.10.0/24 via 10.10.14.1 dev tun0 "
It goes to that IP through 10.10.14.1
how 10.10.14.1 knows where 10.10.10.0/24 is, I don't know
frosty bone
your route says 10.10.10.0/24 goes via 10.10.14.1, and 10.10.14.0/23 goes via tun0
so when you try to ping 10.10.10.147 which is on 10.10.10.0/24, it has to go via 10.10.14.1, but to get to 10.10.14.1 it has to go via dev tun0
so a packet is sent out of dev tun0 addressed to 10.10.14.1, containing instructions to go onto 10.10.10.174 as per routing table

does that mean there are two LANs sitting on a router? I am just trying to visualize it.
"Intel Wireless 3160 (Dual Band Wireless AC 3160)"
wifi (iwlwifi), 34:E6:AD:C4:C1:33, hw, mtu 1500
ip4 default
inet4 192.168.1.22/24
route4 0.0.0.0/0
route4 169.254.0.0/16
route4 192.168.1.0/24```
I have this for my WLAN can I have a device at 169.254.1.11 and try to ping it from 192.168.1.22? or do I need another router for this? How does it work?We don't have enough information to know that. The router at 10.10.14.1 could be directly connected to 10.10.10.0/24, or it could have to go through another router to get there
is that your computers route table?
also I don't really understand it in that format 
placid tree
is that your computers route table?
@thorn stratus yes

you could try to traceroute to 10.10.10.174 to see how you reach it

Can someone pls help me
I have the server code written but when I run the client and server
When I run it in two different terminals it gives me an error because my port number is 65000
But when I try with a different port number it doesn’t work
Can someone help me out

@ember ledge
Here it is
Pls could you help me
With 65000 it works
But when I try it with a different port number it doesn’t work
How do I write this code without the WITH statement
PLEASE HELP
!!!!
I have the project due in two hours
ember ledge
what port number exactly
and what do you mean "doesn't work"
what error are you getting
@hazy zinc
ember ledge
we can't help you without seeing what code you're trying to run
I'm not sure what you mean with is wrong, it's the most correct way to handle a bound socket like that
ember ledge
the alternative is manually closing the socket afterwards but that is prone to not running properly (have to catch all exceptions etc)
the code you sent before works fine for me
please don't send pictures
nobody wants to read that
!codeblocks
errant bayBOT
hazy zinc
Ok when I run the code and choose my port number as 5000
There is an error
How do I fix that
ember ledge
what error
hazy zinc
@ember ledge
ember ledge
we literally cannot help you if we don't know what error you're getting
it works fine for me with port 5000
hazy zinc
How did you do that
ember ledge
do what
ember ledge
it's just a listening socket
you can connect to it using anything you want
I used nc
ember ledge
what exactly doesn't work
I'm asking you the fourth time: please send the exact error you're getting
hazy zinc
If I choose my port number as 5000 it doesn’t connect to the server
Connection refused error
ember ledge
and you changed the listening port in the server?
ember ledge
?
hazy zinc
I was given the client code
ember ledge
you need to connect to the port your server is listening on
hazy zinc
We were suppose to make a server code
ember ledge
the client can connect to anything
hazy zinc
I did
ember ledge
if your server listens on port 65000, you need to connect to 65000
if 5000, then 5000
hazy zinc
If my professor tests it my code will only work if it listens to 65000
ember ledge
it has to be specific
ember ledge
use python3
ember ledge
no you didn't
also you're not parsing the argument 5000 in any way
look at the client code example to see how to parse command line options like you're giving
hazy zinc
I am sorry it is the first time I am doing networking in python
And I am coding the first time
So I am still learning
Sorry to be annoying
But how do I parse the command
ember ledge
the client code has a direct example, using the argparse library
hazy zinc
So do I just write args = parser.parse_args(argv[1:])
Are you telling me to write this statement
Where do you want me to change it
@ember ledge pls could you elaborate more and help me
hazy zinc
Client code

Client and server both working
But the reverse string result file is not printing

I have a bug with socket in Python:
client.py
# Imports

# Variables
ip_address = '10.0.0.195'
ip_port = 10000
txt = 'utf-8'
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
msg = s.recv(1024)
# Code
"""Connect to the server"""
s.connect((ip_address, ip_port))
while True:
var = msg.decode(txt)
print(var)
if var == "quit":
break
# Imports

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# Code
s.bind((socket.gethostname(), ip_port))
s.listen(max_connections)
while True:
clientsocket, address = s.accept()
print(f"{address} connected!")
clientsocket.send(bytes("quit", txt))
Bug: OSError: [Errno 57] Socket is not connected
Even if the server is running, this weird message comes up.
When replying to me, please @ mention me, thanks.

Firstly I would check if the target IP is actually 10.0.0.195 @gilded delta
And that if it is, both computers are on the same local network

get handle to file open for reading

get the number of items in the file

@gilded delta you recv before you connect lol
thorn stratus
@cinder trellis traceroutes in general are quite slow, but you can run them all at once
make each process all at once, then get their results all at once
if you have a lot might be best to make them like 5 at a time
thorn stratus
Are you on windows?
Pretty sure you need to specify a gateway
your just trying to connect to one computer?
destination^ ^mask ^gateway metric^ ^
Interface^
your destination and gateway will be the same, and your mask will be 255.255.255.255 to specify that its just a single ip
I think you can omit the metric and be fine
yep
the error tells you whats wrong
the command requires elevation
you need to do it in a command prompt running as administrator
np
mm no
a different answer on that server fault link you posted said the original command you posted would work but gives me an invalid mask error on my computer
worth a try I guess
are you sure your using the correct interface
which you found out with route print?
yup
Are you sure the computer on the other end responds to pings?
can you show me the full output of route print
I think you might need to put the gateway as 0.0.0.0 not the destination

hi everyone
has anyone worked with SMTP in python before
I need to code a tool which verifies existence of a given email address
has anyone done something similar before with python. I looked on github but was not able to find a working program (maybe I did not install them well? 😦 )
here is an example project I found. I wasn't able to get it running.
thorn stratus
Well many mail servers will prevent you from doing this so you can't enumerate users
The VRFY command is for exactly this thougj
restive blaze
NatyCat, few SMTP servers allow VRFY
there is no way to test except send email with link to verify
thorn stratus
That's what I said
But some mail servers will also not tell you an email address doesn't exist

Hey so I asked this in python help channel and nobody said anything, so figured this would be the more appropriate place for it.
So I'm doing this project that pulls a bunch of data from this site with BeautifulSoup, but the data is sort of nested into other pages on the site, and then those pages nested even further than that, and basically I did the math and estimate that I would have to pull from over 3,000 different pages on the site to get all the data I need. If I webscrape the html from that many pages in one code, would that be like DDOSing the site? I certainly don't want to spam the site with thousands of html download requests all in rapid succession and do anything malicious, but I'm not sure if that would actually do that.
I'm going to bed but @ me if you have any advice or info
gloomy root
Thats not realllllllyyyyyy topical for this channel, but yes that would probably look like a ddos if you tried doing them all at once @marsh trellis
we also cant help you with that if it's against the site's ToS so you might also want to check that 🙂

make sure you're not violating the usage policy of the website

Alright, thanks. Maybe putting a pause in between each html pull would help. Also the website itself is older and doesn't have a ToS. And I was only asking because of what I DONT want to do, all I want to do is pull report data from site, but I dont want to bother them either.
Also where would a question like this be appropriate then?
If not in the networking channel

hi, I want to run a simple socket server from my PC but i can understand why it wont work...
import socket
def server():
host = "192.168.1.158"
port = 5000 # Make sure it's within the > 1024 $$ <65535 range
s = socket.socket()
s.bind((host, port))
s.listen(1)
client_socket, adress = s.accept()
print("Connection from: " + str(adress))
while True:
data = client_socket.recv(1024).decode('utf-8')
if not data:
break
print('From online user: ' + data)
data = data.upper()
client_socket.send(data.encode('utf-8'))
client_socket.close()
if __name__ == '__main__':

heres my server code
import socket
def client():
host = "<public ip>"
port = 5000 # Make sure it's within the > 1024 $$ <65535 range
s = socket.socket()
s.connect((host, port))
message = input('-> ')
while message != 'q':
s.send(message.encode('utf-8'))
data = s.recv(1024).decode('utf-8')
print('Received from server: ' + data)
message = input('==> ')
s.close()
if __name__ == '__main__':
client()
heres my client code
and ive enabled port forwarding
but for some reason i cant make it work
frosty bone
your host might have to not be the public IP
have you tried "0.0.0.0" or "192.168.1.158" for the host instead
oh sorry my bad
I read the host and client the wrong way round
does this work locally?
halcyon jolt
it works locally when the client also uses the internal ip
halcyon jolt
i havent yet no,
frosty bone
worth doing it, make sure incoming TCP from internet on port 5000 is allowed
halcyon jolt
i suspended the firewall and it still doesnt work unfortunately with ethier a local machine using the public ip or a remote amchine using it
wait, no my bad
it just took a while longer though,
thanks!

not a lot other than MySQL servers being connected to over a network
I guess the most interesting things happen because you usually want this network to not be publicly accessible, so there's various interesting network-related things you can do with VPCs and VPNs

I think tcpdump might only know about protocols layer 4 and below
use "tcp port 80"

@snow tulip I'm asking for a listner
ok leave it thanks

whats wrong with those options
@thorn stratus asking me??
thorn stratus
yes
empty solstice
nothing the difference is that LAN is on a local network
and WAN is over internet
thorn stratus
What
empty solstice
umm like LAN is like someone who is connected to your wifi and so he/she is considered as connected in LAN network
and in WAN anyone who is connected to internet is considered as over WAN connected
thorn stratus
What does that have to do with netcat or metasploit
empty solstice
net cat was different I was asking for a python listner
and I searched web so they suggested to use netcat listner or a metasploit listner for that
but I wanted a python listner
so I was asking here
