Posted: Sat Jun 01, 2019 19:47 Post subject: NordVPN easy_script connection
Hi to all.
First of all I want to say that I'm not a professional programmer, so, maybe this little script is not perfect and can be improved, so if you find some that not work so good or you've a better idea method, you're welcome to tell me what is wrong!
So, this script basically:
1. For each country you select, search the top server and pick the best one!
2. Start a watchdog for vpn interface, that check every 60 sec if the vpn is up and running.
3. Start a watchdog for server load, if the current load is over a threshold, change it.
How install it?
Simply copy the script to your preferred place, I prefer copy it to /opt/bin and make it executable with chmod ugo+x /opt/bin/easy_nordvpn
How can I run the script?
I usually have one script that I call at boot, so I prefer use an intermediate script to do all the dirty works, and from the Administration -> Commands -> Startup I call it, so in my case inside the Startup field I've /opt/startup_script.sh and inside the startup_script.sh I've sleep 30 && /opt/bin/easy_nordvpn start
So at the end you've to put sleep 30 && /opt/bin/easy_nordvpn start in your startup
Now you've to configure your vpn client like always, go to Services -> VPN -> OpenVPN Client and configure the client like NordVPN suggest.
The very next step is to configure the script, is quite easy, you've to configure only few option, are all inside the easy_nordvpn script, so just nano or vi the script. The most important configutation is:
Code:
# Specify, comma separated, the country you want to connect from vpn, can be more than one.
# Just remember that must be the contry number, like 106 for Italy, or "228,202" for US and Spain at the same time
COUNTRYSELECTION_ID=""
Then
Code:
# Max load is usded to check the actual server load, if the load go over the MAX_LOAD, the script will change the vpn server.
# Don't select a too lower value, in this case the script will always change the server
MAX_LOAD=35
You can look inside the script to see other options, normally the value inserted are quite good, but you can change it if you need it.
So now you can reboot your router or just start the script via ssh with easy_nordvpn start
What I can do with the script?
Here a list of commands:
Code:
easy_nordvpn start -> This must be used only at boot, so don't use it if you don't know what're you doing
easy_nordvpn stop -> This stop the script execution
easy_nordvpn restart -> This will restart the entire script
easy_nordvpn status -> This check the actual status of vpn, actually check if connected and current server with load
easy_nordvpn force_connection -> This force a new connection, so if you use it the script connect to first best server.
easy_nordvpn interface_check -> This check only the VPN_INTERFACE, in order to check if is up and working
easy_nordvpn checkload -> This check the current server load, if is too low, make a new connection.
(note that the script connect to the new best server, but maybe this server already have higher load so at the next check the script will change again, and so on)
I want to thank egc for the infinite patience!
For now is all, if you've any question please ask, I would try to do my best to change possible errors.

First of all, thanks for creating this script!!
However, I'm having great struggles installing JQ.
I have no idea what it is and I can't figure out how to install it correctly.
PuTTY is currently displaying the next message:

Let's see if all is good to start ...
Jq bin not found, I can't work without it, please install it and try again!!!
I just can't get Entware installed. Tried everything. This is the best result I got:

I just changed (as far as I know) the countryselection to use the US servers.
Mmm. I suspect that you're not with root privilege.
Let me guess, you run the ssh connection from winscp?
In theory the script will start after a reboot, if you put the autostart line
So you can try to reboot the router and see if works.
But if you want to try by hand via ssh connection you've to be root, so use putty to connect and use root user (obviously I'm thinking that you're not root, maybe I'm wrong)
I've to investigate why there's permission denied error
PS try to
chmod 777 pathtonordvpn script file
Maybe the permission is wrong
