The installation is in a holidays house (so no permanent internet access)
I have a 4g-Routerm (ROUTER-1 = huawei B525-b23) that enable the internet access. I switch it on one day a week.
I have another router (ROUTER-2 = GL-MT300N-V2).
ROUTER-2 is always plugged on electricity.
On ROUTER-2 is connected through ethernet port a Raspberry-Pi3 (with Home Assistant on it).
On ROUTER-2 is connected through WIFI a Camera IP
ROUTER-1 and ROUTER-2 are connected together through ethernet.
When ROUTER-1 is not plug to electricity, none have acces to internet, but it's not an issue.
The camera save picture on the Rapbery Pi3, the Home Assistat is recording some sensor data.
When I switch on the electricity on the ROUTER-1, everyone have access to internet.
What I want is to have remote Access to my router-2 and my Rasberry and my Camera when ROUTER-1 is online
How should I do ?
Hi I can think of two solutions for this setup but both involve buying a second hand cheap router.
I think the use of a single router would make this setup a lot easier. Any router would work that supports:a USB 4g Modem to be attached to it, and has support for setting up a openvpn server and you need to be OK with leaving the Internet on all the time just make sure you dont have any services running that use up bandwidth and you should be ok. You can can connect both raspberry pi and IP camera to that router. Setup Openvpn server open the UDP port required and download the certificates, You should be able to vpn into your network and manage it through SSH or something remotely.
The second option is tailored to you but still requires swapping the 4G Modem with another one that supports these things: Wake on LAN, openvpn server, supports ssh into it over LAN and either has 4G support through a sim card slot or a usb port with modem support.
You can then have it setup so this new Router-1 is switched off with wake on lan configured on it and the raspberry pi to send the magic packet. You can use something like this to get an idea of how WoL https://www.lifewire.com/wake-on-lan-4149800. You can use cron on your raspberry pi to send WoL signal to Router 1 once a week which would eventually give you internet access once the router is up. You have to setup a vpn server on it and forward the required port and download the certificates. When your scheduled WoL cron runs make sure you are able to connect through vpn then access network resources you wish, at the end when you are done you can ssh into the router-1 and turn it off.
I hope this helps. I had a look at the router models you are using and it doesnt leave you with many options. You can get cheap second hand routers online that support everything that is required.
I am following this instruction http://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/ConfigureForiOS. Everything works until section Set the iOS Device Proxy.
Once I set the proxy on my iPhone, I can't connect to the internet from the phone anymore. Not even accessing the echo page, which I could access before turning on the proxy on the phone. I already installed the root cert on my phone, the makecert add-on on Fiddler
Could someone help with ideas to diagnose the issue here? Thanks,
What might be stopping your iphone from reaching your Fiddler machine on the port specified, usually 8888?
Have you a firewall on the Fiddler machine? You might need to open
the port.
Does your LAN have an automatic redirect to a login page? Ours
does, so I have to disable the proxy on the iphone while I login,
then reenable it.
Does your LAN expose the IPs of cable-connected machines to WIFI
users? Not all do.
Can you browse a simple web page on your Fiddler machine from your
iphone, before starting fiddler or doing any proxy configuration?
You might need to get really serious and install a ping utility on the iphone.
I was trying to study the HTTP(s) requests/response that the apps from my phone are sending so this is what I went ahead and created.
I turned my Raspberry Pi as an access point with 2 wifi usb dongles. One for my phone to connect to the "TEST" network and the second connected to the internet. Everything works fine and my phone is able to access internet via my RPi.
Now I setup MITMproxy (in transparent mode) so that I can sniff the traffic to-from from my phone apps. I installed the mitmproxy certificate on the phone and the traffic shows up fine on the mitmproxy console.
Final step - To make the web traffic data analysis part easier I found on the net that Paros Proxy might be able to help (show the traffic from mitmproxy) in a more readable way. - THIS IS NOT HAPPENING
I am assuming there is some setup required for ParosProxy so that it can be linked to mimtProxy / network interfaces which I am not able to achieve. Can any one please help with this?
ParosProxy dashboard doesnt show any traffic. As far as the settings (Tool->Options) the default settings are there i.e. for local proxy (host = localhost and port = 8080). I couldnt find much documentation about ParosProxy on the web.
My network interfaces on the RPi is as follows :
wlan0 (connected to internet) - DHCP
wlan1 (Access Point to which the phone apps connect to) - static IP (gateway 192.168.10.1)
Just in case there is some other tool that could help me achieve the same (a GUI/better dashboard to analyse mitmproxy traffic in real time) I am pretty open for it.
Yes there is a better option: OWASP ZAP https://www.owasp.org/index.php/ZAP :)
It was forked from Paros ~ 5 years ago, is very actively maintained and pretty well documented.
See https://github.com/zaproxy/zaproxy for links to the online user guide, FAQ user and developer groups.
FYI we have info on how to get ZAP runnin on a Pi: https://github.com/zaproxy/zaproxy/wiki/zappi but that doesnt include setting up wiki access - it would be great if we could update that page with the necessary steps :)

I implemented a web service for an Android application. The web service is running on my local host (192.168.1.2). Using the Android emulator I succeeded to connect to web service. The I tried to connect my Android device using debugging mode to web service but it didn't work. So my question is if it is possible to connect an Android device to this web service that is running on my local host (192.168.1.2) without using a real IP ?
It's much simpler way supported by google!
Connect your phone via usb to computer and enable usb debugging
On your computer open Chrome browser and type exactly this address: chrome://inspect/#devices
Now you can link your computer port to your device port by port forwarding button. On my computer I have service on address localhost:61437 and I just linked it to device's 8081 port. Remeber to check 'Enable port forwarding' checkbox
screen from service on my computer ( localhost:61437 )
screen from my mobile browser with the same service ( localhost:8081). And that's it. Also you use this service address in your application
Did you already solve your problem? I also got a problem like you. These are the steps that I already done:
unplug lan cable or turn off any other internet connection from your pc.
connect your android mobile to your pc using usb.
turn on usb tethering
back to your pc. check your ip. mine is 192.168.42.37
check your webservice app in your pc. let's say http://192.168.42.37/webserviceapp
back to your android mobile. try this url http://192.168.42.37/webserviceapp
Now you can access your webservice app in your pc from your mobile phone.
Well your localhost is 127.0.0.1 (or ::1) and your LAN IP is 192.168.1.2. Each pc/device that are connected under your LAN could reach your webservice on IP 192.168.1.2
Your Android device must be so connected under the same LAN maybe through Wifi connection so it will be able to talk with 192.168.1.2.
If you can't connect your Android device under the same LAN eg you have just a 3g connection you need to play with your router/firewall to redirect all incoming traffic (maybe just the http traffic) from your public ip to you private ip (192.168.1.2)
Hope this help
I'll throw in my process, since nothing on SO worked for me. Here are the steps I took to connect my physical android device to the web service running on my laptop (connected to the phone) on localhost:
Enable USB debugging on your Android device
Run your web service on your machine. My web service runs on localhost, port 3000 in development: http://localhost:3000/api/...
Run ifconfig (Unix), or ipconfig (Windows)
Find your machine's inet address on your LAN interface. Mine is 10.0.0.121 for interface wlan0. Externally, it is 68.43.XX.XXX, which is not the address that you want to use.
Use the LAN IP since you are connecting to your service on LAN, otherwise you might get an econnrefused (connection refused) error due to firewall rules
Build your http URL with that IP address, and the port that your web service is running on. For me, it's http://10.0.0.121:3000/api/...
When you launch your app, you should connections to your local web service in logs, Wireshark, etc, and you should see the desired activity/data in your Android application.
I had the same issues, researched a lot then found out that you have to explicitly make changes in your firewall settings. Your firewall is blocking your code to be accessed from external source. So, all you need to do is, go to firewall settings, add port 80 (in my case since, I am using Apache http Server) for inbound and outbound. Now, you can test it on your phone's browser http://192.16..**:80/
I've done that on a Mac using GasMask and Charles Proxy Server. Your phone and your computer have to be on the same network.
say the webservice url you want to access is at http://api.xyz.com, you first use GasMask to point that url to your localhost, then use Charles to set up a proxy server. Then you go to the settings on your phone, go into Wi-Fi, long-press the network you are connected to, choose Modify Network, and enter the proxy settings Charles gave you.
In my case, nothing of these solutions works because Windows firewall blocks it, but putting a rule on the firewall hasn't effect.
The problem in my case is that my laptop is connected with Wifi and Windows had the Wifi connection like a Public network. I must to change the network connection to Private network. http://www.comofuncionatodo.net/tecnologia/informatica/como-cambiar-de-red-publica-a-red-privada-en-windows-10/
I agree with the other answers as good approaches if you don't want to expose your DEV webservice on the internet. However, it's much easier if you do just expose the webservice. There's a number of free DNS services, but I've found no-ip to be the easiest to set up. I use it for exactly the purpose that you asked about; so I can test with my DEV webservice on a real device.
If you choose to go with no-ip (I have no affiliation with that company, it's just the one I've used and am familiar with), you can get a free publicly accessible URL like http://MyExampleWebServer.no-ip-org, and no-ip has a utility you can install so even if you're behind a dynamic IP, it will always keep the correct external IP associated with that URL. If you're working from your house, then you'd just need to make sure you port forward traffic from port 80 to your internal 192.x.x.x IP address (or whatever port you use; maybe 443 for ssl).
It's as easy as that, and now you can hit that webservice from any device that can access the internet.
I haven't worked with it, but I believe dyndns also offers a similar service.
This solution is for GAE development server in Eclipse
Step 1: Get the LAN IP
Goto your Windows Command Console (Press Win+R, then type "cmd"). In the console, enter "ipconfig". You will see a list of display. Under Wireless LAN adapter Wi-Fi, get the IPv4 Address. It will be something 192.168.x.x
LAN IP : 192.168.x.x
Step 2:
Go to Eclipse, Open the Configured server
Under Properties of GAE Development Server -> Local Interface address to bind to, enter the LAN IP address, and save.
Step 3:
Now you can access the GAE server by
http://192.168.x.x:8888/
8888 - Refers to the Port Number, as mentioned in the GAE development server
In order to access local web services using their own server hosts rather than IP addresses with ports, do these following steps:
Make sure your Android device and your local machine are on the same network.
Install SquidMan on your Mac, Linux, or any other Proxy Server.
Configure the proxy server's HTTPPort (ex. 5555) and clients (ex. 192.168.0.0/24) to your own network mask, and run the proxy server.
You are either using the web services in:
a. A web browser: Configure the proxy settings of your Android device from Modify WiFi networks.
b. Android application:
Set up the Proxy for your HTTP client. If you are using Volley, check this out: Volley Behind a Proxy server.
You can now connect to it by using whatever URL you are using on your host to connect to the web service (ex. http://my-local-machine.com)
Hint: If you got 4xx response codes, make sure your web service allows connections from other non-local-hosts.
If you are referring your localhost on your system from the Android emulator then you have to use
http://10.0.2.2:8080/
Because Android emulator runs inside a Virtual Machine(QEMU) therefore here 127.0.0.1 or localhost will be emulator's own loopback address.
I'm trying to test my iPhone application on the device.
I have a mac computer which stores my development environment.
Right now I can only access PHP files using the http://localhost/PHPFileLocation
which does not work when I try to test my app on real device.
How do I configure apache2 to be accessible from outside?
Is it possible to configure it to a specific IP address?
I want to reach some php scripts located on my development machine running apache2 from my iPhone device.
Thanks
If your computer has a WiFi card then you should be able to attach the iPhone remotely to a ad-hoc Wifi network created on your dev machine.
I'm assuming your Mac is behind a router. You should be able to configure your router to port forward connections to your WAN facing IP address to port 80 (the HTTP port) on your Mac - see http://portforward.com/ for some help.
You may also need to turn the firewall off on your Mac.
Once this is set up correctly you can hit http://yourexternalIP/PHPFileLocation in your iPhone app and this will be directed by your router to the Apache2 server on your Mac. The external IP is normally found on your router's admin page somewhere.
