Can connect to VPN through terminal (openvpn) but not through NetworkManager

Postby yaomtc » 2017/04/22 00:10:39

When I use the config file and certificate provided by my VPN, and the openvpn command line tool, I'm able to connect. However, even when I followed their directions exactly, NetworkManager wouldn't work with the VPN. It just says "Connecting" for a while and then gives up, apparently. Here's the messages:

I am pretty convinced that this is SElinux issue.In order to verify use "setenforce 0" and try again.
If the certificates ,keys etc are copied in one of the following directories,they will retain correct selinux context:
/home/username/.cert/ or in /etc/pki/
Otherwise use the ”semanage fcontext” and after that "restorecon" tool.

Tried setenforce 0, same/similar results. Messages are below. Certificates have been in the ~/.cert/nm-openvpn folder. I don't know how to use those tools you mentioned, I can look at the man pages when I get back later?

Also, might the fact that I have consistent network device naming disabled (for the purpose of Maya, especially license activation) have any effect here?

If ”setenforce 0” didn't allow the connection-then it's not selinux.
Check the permitions of the .cert folder and its content.

Try to temporary dropping the firewall and run another test.After that start it again.
If you are using the default firewalld it should be like:

Code: Select all

systemctl stop firewalld && firewall-cmd --state

to enable:

Code: Select all

systemctl start firewalld && firewall-cmd --state

The .crt and .key files can be read and written by me. Group can read, and others can read. Should group/others have no access? That's how it is for the .pem files that I assume NetworkManager generated.

Re: Can connect to VPN through terminal (openvpn) but not through NetworkManager

Postby hunter86_bg » 2017/04/29 06:33:38

Change the permissions to 600 and try again.It's not supposed that others to read it.Set the same permission to the folder.

It may be a bit late, but as it does not seem that a solution was found, it might still help others you or others.

If you followed exactly the instructions in the link you provided, it won't work.

The instructions for Centos are at https://support.nordvpn.com/hc/en-us/articles/206927749-Linux-setup, and it won't work neither. But in this page, you will find a link to download the certificates (at this time, it is https://nordvpn.com/api/static/ca_and_t ... icates.zip)

You will have to unzip this file an put the certificate and the key corresponding to the server you want to connect to into your ~/.cert directory. (It won't work from another directory if you have SeLinux enabled, although SeLinux will give you notifications about how to change the configuration, either by copying the files to ~/.cert or letting SeLinux access these files from somewhere else.)

Then you will have to select the certificate instead of the .pem certificate that comes from the configuration file (The file has the .crt extension instead of .pem)

Then you will have to click "Advanced settings", select the TLS Authentication tab", and chose the key corresponding to the server and certificate in the "Use additional TLS authentication area". Then select 1 for the Key direction.

After that, it should work. If it does not and you have SeLinux enabled, you will receive an SeLinux notification with the instructions to solve the problem.

Two things to note:

1) If you use IPv6, your IPv6 address might leak. There is no known solution (meaning no solution known to me) than to disable IPv6. There is a page about how to do this on the NordVPN site: https://support.nordvpn.com/hc/en-us/ar ... 5002750169. But beware that this change has to be made on each restart of your computer. To check if you IPv6 address is leaking, you can use https://whatismyipaddress.com/ (Not many testing sites will give you this information.) To check if IPv6 is enabled on your computer, use http://ipv6-test.com/

2) You should also test for DNS leaking. (https://dnsleaktest.com)

2) If you lose the connection with the VPN server, you will automatically fall back to non VPN access. You should configure your firewall to disable direct access and allow only access through the VPN server.
