I am using ZyXel reach as Android application and want to connect it to my Fritz!Box.
Before I used CSIP simple, but it uses too much resources from the phone, so I switched to ZyXel reach.
The log file of ZyXel reach shows 403 Forbidden SIP Server.
It does not matter if I try to connect from outside and a stunt server or if I try to connect within the network (Wifi), I get the same result.

I'm developing a Flutter app on a physical android device, I don't know much about networking and I'm having a trouble using an API from the phone to a local database on my laptop.
I reviewed all the answers in this post
Cannot connect to localhost API from Android app
Nothing seems to work for me, I'm using Apache server on XAMPP, and the API works just fine from the laptop (127.0.0.1:8000/api/Students) but when I try to access it from the phone it doesn't work (I replaced 127.0.0.1 with the IP of my laptop which I took from ipconfig)
XAMPP control panel
when I try to access the server from the phone using laptop-IP:80 it access normally the same with laptop-IP:80/phpmyadmin
XAMPP dashboard
but only when my phone is connected to the laptop mobile hotspot, when I connect the two devices to the same WIFI network it shows that it's unreachable:
but when I try laptop-IP:8000/api/Students this happens:
this site can't be reached
I tried to modify Apache httpd.conf:
#Listen 12.34.56.78:80
Listen 8000 <-- Added this
from what I understood this makes the server listens to port 8000 but I'm left with the same problem
NOTE: all the pictures show my attempts to use the API on my phone's Chrome browser
You need to do some tweaks to the url to access it in the device as localhost is only known to the machine not the devices on which the app is running.
The urls are different for different devices
Emulator
Real phone (with usb debugging)
1.Emulator
static const baseUrl = "http://10.0.2.2:8000";
2.Real Device
static const baseUrl = "http://localhost:8000";
Additionally you need to run these command in your cmd,
adb reverse tcp:8000 tcp:8000
Now your requests would go like:
get('$baseUrl/api/Students');
I want to control my raspberry pi with my Google Home at college, but everything I find involves a server and opening a port which I can not do on my schools network.
Is there another way I can do this?
The Google Home has no way to directly control other devices on the same network or through other wireless protocols. Everything goes through an Internet-based service and expects to communicate with devices via a server-based proxy. How that server communicates with the device is up to the developer.
Depending on your needs and capabilities, you do have a few options.
One option, for example, is to use a tool like ngrok to create a tunnel between the device itself and a service run by ngrok on the public Internet. Calls to the public https address are sent to a service running locally on your device, and you can handle it accordingly.
Another is to have your device connect to a server and listen for command changes, and then execute those changes. If you don't want to run a server, you can even use something like Firebase - have your device listen for changes on the real-time database (which can use the HTTPS port to communicate as a client, so you don't open anything) and have something like a Firebase Cloud Function act as the webhook for your Action.
Go through this blog post: http://nilhcem.com/android-things/google-assistant-smart-home
You will have to set up a OAuth server but as #Prisoner said you can use ngrok to tunnel the device to internet, BUT I would recommend using "localtunnel" as it provides a free static url and the set-up is also easy. NO Port Forwarding is required with this method.
More info on localtunnel setup:-
How to generate fixed url with ngrok
Moreover you need to activate the OAuth server only once for account linking & than you can close it.
The simplest way I can think of is to expose your Pi to the internet (using port forwarding, ngrok, or whatever) then set up an IFTTT Google Assistant trigger to invoke a webhook which points to your exposed Pi.
I’m trying to build a voip app with openfire on server-side, Icelink on client-side in xamarin android.
The problem is the openfire client(running on port 5222) does not respond at all even from the local host.
For example when i try 192.168.1.xx:5222 in my browser, it is always in acquire stat and does not response anything.
I have checked all the primitive things and tested the server with Spark and it works fine!
I have a server written on C++ REST SDK.
There's http_listener which listens to "http://localhost:34568".
When I try to send a request in browser or from the client to localhost it works fine and I get the responses from my server. But the point is to use the application in network. And here where the problem comes.
When I try to request the server from the other PC using IP(192.168.1.103:34568) I get "HTTP Error 400. The request hostname is invalid."
I'm aware that that could be some firewall issues but it's turned off. Also I tried to set port rules in brandmauer and it didn't help.
And even more! I got XAMPP running Apache server and when I do the same thing but with (192.168.1.103:80) I do get the response from Apache and have an access.
Anybody had something similar or somebody knows what the problem is about?
Listen to local ip address or to your network name (dns):
"http://xxx.xxx.xxx.xxx:34568" or
"http://your_network_name:34568"
So, if you have multiple network adapters, you can choose which one.
Using XenApp6 on Windows 2008 R2 I have the windows Calculator as a test app. Apps are set to run on the server, and are not streamed to the client. When running Calculator from inside the network it runs as expected.
However, when accessing the app from an external web browser or Citrix Receiver, the client always times out and the Calculator app is not launched. I see incoming traffic on port 1494 (which is open) but there is no response from XenApp.
For both internal and external, I log in as Administrator and can see the citrix management console showing my test Calculator app.
Any ideas why it's timing out and not launching from the internet?
Thanks.
Chris
If the Citrix server's internal IP is being NATted to an external IP you may need to set an alternate address using altaddr on the Citrix server. Try this: Download the ICA file that the Citrix server passes when you launch a published app from a web browser, open it in a text editor, and see what FQDN or IP it is trying to connect to.
