I wanted to use nordvpn client on my Raspberry Pi 3B+.
So far so good I downloaded the client 3.8.6 and logged in.
It works using the technology OpenVPN, but when I want to use nordlynx it connects to a server but I cannot download/surf anywhere.
Ping does work but no data transfer.
Has anybody any suggestion to fix this?
Do I need the wireguard module in addition to the nordvpn?
The support of nordvpn did not provide anything useful, only reinstall and iptables flush was suggested...
Many thanks in advance

I'm really looking for advice and a starting point more than anything. So I'll try my best to explain my end goals and the challenge. I want to set up a local WiFi connection (P2P) between a Rpi3 (or any embedded system really, running linux) and a laptop. The Pi should be the server and laptop the client. The raspberry PI is going to be reading samples over USB from an SDR. I want the laptop to be able to connect to the network the pi throws up, and be able open a browser and view the results. I'm guessing what i need to read up on is ports/sockets and web programming in general. The cheepy IoT sensors and light bulbs seem to be able to do this (opening network and forwarding data) relatively easily but i cannot find any information online to aid in my quest. All the Best and thanks in advance.
Since the embedded system will be running Linux, you can do something along the following lines:
setup the wifi as an Access Point (example). Also setup DHCP Server (example), so the wifi will assign an IP address to connecting laptop.
Install a webserver (e.g. Apache).
Create the webpage/ web application you need to "serve" the data. Install this into Apache.
Ask follow-up questions if you like.
I've got an Arduino hooked up to a Raspberry Pi 3 via USB and feeding some analog data to a database I created.
I've set up a database on my Raspberry Pi 3 (have everything set up phpMyAdmin and MySQL). I'm feeding data into it and it works. I want to access the database through my Windows machine, though. I have Apache, phpMyAdmin, and MySQL all installed.
I'm pretty sure I've edited/copied all files correctly and I can get to localhost/phpmyadmin on my windows machine.
I'm just not sure what I need to do to get to my Pi's database from there. Working with Wifi currently. I don't necessarily have access to a router since I'm working of my apartment building's wifi. I have VPN installed on Pi but haven't really configured it yet if that's the route I need to take.
Any help appreciated
Since the database exists on your Raspberry Pi, you don't need to have MySQL installed on your Windows machine. You generally only need one MySQL server which can be accessed by many clients. In this case, since you want to use phpMyAdmin to access the data, you have the option of installing phpMyAdmin on your Windows machine or the Raspberry Pi. I highly recommend putting it on the Pi, because it simplifies the connection process to have it on the same machine that MySQL is using.
You'll need some supporting software to get phpMyAdmin running; a web server and the PHP interpreter. These are all easily available on the Raspberry Pi (depending on your operating system, of course; I use Raspbian and there are packages distributed for each). Then you'd use the web browser on your Windows machine to access the web server on the Pi (likely through the IP address; you'll have to query your Pi to figure out what the address is, perhaps with ip addr at the command prompt).
You can certainly use phpMyAdmin installed on your Windows machine instead, but then need to ensure that the MySQL daemon is listening for network connections and that you have a user permitted to connect from an external network connection (I'm seeing that many packages are restricting both of these, as a security precaution, in their distributions now). It's easy to enable yourself, but easier to just connect from a local PHP instance.
Unless your machines are on two different networks or you wish to connect to your home network from an outside connection on the Internet, you shouldn't need the VPN for this project. Your wifi is likely supplied by a router that's giving you a local address and will allow you to connect to other machines on your local network segment, so once you find the IP address you should be able to connect directly.
So I had been working on a project that is able to setup an Access Point and redirect traffic through another interface (can be wired or wireless).
Now there have always been issues between hostapd and wpa_supplicant, I needed to create an access point on one wireless interface and route it through another wireless interface. But while that interface is managed by network-manager hostapd is unable to start an access point on that interface.
Ways to work around:
I can run these commands and kill wpa_supplicant
sudo nmcli nm wifi off
sudo rfkill unblock wlan
But this turns off all wireless interfaces and I need one connected to the internet so I can route the traffic.
Another work around, which I used and is a lot more elegant:
adding this line to the NetworkManager.conf file
[keyfile]
#unmanaged-devices=mac:d8:5d:4c:9a:72:60
This actually worked flawlessly!
Until a recent update of hostapd to version 1:2.5-2+v2.4-3
Are there any other workarounds so that my wireless interface is not managed by wpa_supplicant?
I'm running Kali Linux.
Okay so for anyone having the same issue, you can also add
[keyfile]
unmanaged-devices=mac:d8:5d:4c:9a:72:60, ,interface-name:wlan1
that 'interface-name' option solves the problem!
I have an IoT device (standalone) that I need to debug Wifi connectivity (if we're sending up the right requests, or if they're coming down proper). I have 5 secure domains that I need to log all traffic to and from. I can get any new hardware/software needed, but I need to basically store all activity and then use a service to upload remotely for comparison on the server side.
Any great suggestions on best approaches for this? I can't install a proxy on the device, so Charles/Wireshark (my regular go-tos) are out. I can buy a router and setup DD-WRT or something, or just root a laptop with a special brew of linux.
Please advise. I need to get the setup put together as quickly as possible. Trying to debug a serious problem.
I have a system named Windchill which runs in a CentOS 5.7 virtualbox;
The system consists of apache, oracle 11g, listener, windchillDS(openLDAP) and the application core (method server) which is a java process. All installed in the same vm(monolithic)
My question is related with the network, The system runs smooth on the network, but once I remove the network cable it stops working and the method server keeps restarting with the socket timeout error.
Im not a IT specialist, I manage the internal configuration of the system and I dont have an specialist to help me right now but I need desperately to make it run non networked in a laptop to show it for a customer.
I just want a hint of where may be the problem:
Does oracle runs non networked? Which configurations do I need to make it run without a network?
Maybe the problem is the listener?
I guess the problem is the oracle because of the socket timeout error with the database but Im not sure...
Sorry this is long and probably needs more explanation, please ask whathever you want!
I found this tip in another forum specific for the windchill product(login needed)
http://portal.ptcuser.org/p/fo/st/thread=52005&posted=1
It is related with Linux configuration to resolve the IPs:
"Edit your /etc/resolv.conf to look like this when not connected to a network:
domain local domain
search localdomain
nameserver 127.0.0.1"
Worked perfectly!
Thank you for your prompt answers guys!!!
