I'm suffering random disconnections with OpenVPN. I don't know much about the subject, maybe you can point me in the right direction? Here is the tail for /var/log/messages, it contains a <warn> and other relevant-looking lines:Jul 15 21:27:58 notebook NetworkManager[907]: <info> Tunnel Device: tun0Jul 15 21:27:58 notebook NetworkManager[907]: <info> IPv4 configuration:Jul 15 21:27:58 notebook NetworkManager[907]: <info>   Internal Gateway: 10.8.0.65Jul 15 21:27:58 notebook NetworkManager[907]: <info>   Internal Address: 10.8.0.66Jul 15 21:27:58 notebook NetworkManager[907]: <info>   Internal Prefix: 32Jul 15 21:27:58 notebook NetworkManager[907]: <info>   Internal Point-to-Point Address: 10.8.0.65Jul 15 21:27:58 notebook NetworkManager[907]: <info>   Maximum Segment Size (MSS): 0Jul 15 21:27:58 notebook NetworkManager[907]: <info>   Static Route: 10.8.0.1/32   Next Hop: 10.8.0.1Jul 15 21:27:58 notebook NetworkManager[907]: <info>   Forbid Default Route: noJul 15 21:27:58 notebook NetworkManager[907]: <info>   Internal DNS: 10.8.0.1Jul 15 21:27:58 notebook nm-openvpn[5675]: Initialization Sequence CompletedJul 15 21:27:58 notebook NetworkManager[907]: <info>   DNS Domain: '(none)'Jul 15 21:27:58 notebook NetworkManager[907]: <info> No IPv6 configurationJul 15 21:27:59 notebook NetworkManager[907]: <info> VPN connection 'Some VPN' (IP Config Get) complete.Jul 15 21:27:59 notebook NetworkManager[907]: <info> Policy set 'Some VPN' (tun0) as default for IPv4 routing and DNS.Jul 15 21:27:59 notebook NetworkManager[907]: <warn> /sys/devices/virtual/net/tun0: couldn't determine device driver; ignoring...Jul 15 21:27:59 notebook NetworkManager[907]: <info> VPN plugin state changed: started (4)Jul 15 21:28:44 notebook NetworkManager[907]: <info> VPN plugin state changed: stopping (5)Jul 15 21:28:44 notebook NetworkManager[907]: <info> VPN plugin state changed: stopped (6)Jul 15 21:28:44 notebook NetworkManager[907]: <info> VPN plugin state change reason: 0Jul 15 21:28:44 notebook avahi-daemon[910]: Withdrawing workstation service for tun0.Jul 15 21:28:44 notebook avahi-daemon[910]: Withdrawing address record for 192.168.0.5 on em1.Jul 15 21:28:44 notebook avahi-daemon[910]: Leaving mDNS multicast group on interface em1.IPv4 with address 192.168.0.5.Jul 15 21:28:44 notebook avahi-daemon[910]: Interface em1.IPv4 no longer relevant for mDNS.Jul 15 21:28:44 notebook avahi-daemon[910]: Joining mDNS multicast group on interface em1.IPv4 with address 192.168.0.5.Jul 15 21:28:44 notebook avahi-daemon[910]: New relevant interface em1.IPv4 for mDNS.Jul 15 21:28:44 notebook avahi-daemon[910]: Registering new address record for 192.168.0.5 on em1.IPv4.Jul 15 21:28:44 notebook nm-openvpn[5675]: SIGTERM[hard,] received, process exitingJul 15 21:28:45 notebook NetworkManager[907]: <info> Policy set 'System em1' (em1) as default for IPv4 routing and DNS.Jul 15 21:28:45 notebook NetworkManager[907]: <warn> error disconnecting VPN: Could not process the request because no VPN connection was active.Jul 15 21:28:45 notebook NetworkManager[907]: <warn> (5) failed to find interface name for indexJul 15 21:28:45 notebook NetworkManager[907]: nm_system_iface_flush_routes: assertion `iface != NULL' failedJul 15 21:28:45 notebook NetworkManager[907]: <warn> (5) failed to find interface name for indexJul 15 21:28:49 notebook NetworkManager[907]: <info> VPN service 'openvpn' disappeared
