Tips
|
|||
|
|
----
|
|||
|
|
|
|||
|
|
|
|||
|
|
- If using qubes-vpn, check the VPN service’s log in the VPN VM by
|
|||
|
|
running:
|
|||
|
|
|
|||
|
|
.. code:: bash
|
|||
|
|
|
|||
|
|
sudo journalctl -u qubes-vpn-handler
|
|||
|
|
|
|||
|
|
|
|||
|
|
|
|||
|
|
- Always test your basic VPN connection before adding scripts.
|
|||
|
|
|
|||
|
|
- Test DNS: Ping a familiar domain name from an appVM. It should print
|
|||
|
|
the IP address for the domain.
|
|||
|
|
|
|||
|
|
- Use ``iptables -L -v`` and ``iptables -L -v -t nat`` to check
|
|||
|
|
firewall rules. The latter shows the critical PR-QBS chain that
|
|||
|
|
enables DNS forwarding.

VPN does not reconnect after suspend
|
|||
|
|
------------------------------------
|
|||
|
|
|
|||
|
|
|
|||
|
|
This applies when using OpenVPN.
|
|||
|
|
|
|||
|
|
After suspend/resume, OpenVPN may not automatically reconnect. In order
|
|||
|
|
to get it to work, you must kill the OpenVPN process and restart it.
|
|||
|
|
|
|||
|
|
VPN stuck at "Ready to start link"
|
|||
|
|
----------------------------------
|
|||
|
|
|
|||
|
|
|
|||
|
|
After setting up OpenVPN and restarting the VM, you may be repeatedly
|
|||
|
|
getting the popup “Ready to start link”, but the VPN isn’t connected.
|
|||
|
|
|
|||
|
|
To figure out the root of the problem, check the VPN logs in
|
|||
|
|
``/var/logs/syslog``. The log may reveal issues like missing OpenVPN
|
|||
|
|
libraries, which you can then install.
