Ive installed and configured the priunl vpn client same as i did on my other Ubuntu 16.04 machine. About 15 seconds after i make a connection it gets killed and I cannot figure out why.



syslog shows the interface being removed by ntpd

So far I have tried:




  • marking tun0 interface as unmanaged in network-manager configuration

  • stopping network-manager

  • forcing ntpd to ignore virtual interfaces by adding the -L parameter


So far nothing worked.



UPDATE
Removing network-manager completely breaks cinnamon so this is not an option, however I increased the log level for NM to DEBUG

linux-mint openvpn networkmanager







share|improve this question

























  • Tunnel starts up, but after 25 seconds, you get an interrupted system call (timeout?), followed by a SIGTERM (possibly as consequence). So the question is where this interrupted system call comes from, and what exactly is causing it. If you can run the priunl OpenVPN client somehow with more verbose logging enabled, that would help. If ntpd is interfering for some reason, stopping ntpd and trying without it is the obvious experiment.

  • By the looks of it it is network-manager thats stopping it. I cannot rmeove network manager because cinnamon depends on it

  • I have battled with network manager before, and lost, which is why I've removed network manager from my system. Though I hear it's not as bad as it was when I had to make this decision. Sorry, can't help you here. Possibly you can configure network manager to leave all tun/tap interfaces alone.

  • Yes unfortunately Cinnamon relies on Network Manager, which means i cannot remove it. I tried but it breaks the desktop environment.

Ive installed and configured the priunl vpn client same as i did on my other Ubuntu 16.04 machine. About 15 seconds after i make a connection it gets killed and I cannot figure out why.



syslog shows the interface being removed by ntpd

So far I have tried:




  • marking tun0 interface as unmanaged in network-manager configuration

  • stopping network-manager

  • forcing ntpd to ignore virtual interfaces by adding the -L parameter


So far nothing worked.



UPDATE
Removing network-manager completely breaks cinnamon so this is not an option, however I increased the log level for NM to DEBUG

linux-mint openvpn networkmanager







share|improve this question

























  • Tunnel starts up, but after 25 seconds, you get an interrupted system call (timeout?), followed by a SIGTERM (possibly as consequence). So the question is where this interrupted system call comes from, and what exactly is causing it. If you can run the priunl OpenVPN client somehow with more verbose logging enabled, that would help. If ntpd is interfering for some reason, stopping ntpd and trying without it is the obvious experiment.

  • By the looks of it it is network-manager thats stopping it. I cannot rmeove network manager because cinnamon depends on it

  • I have battled with network manager before, and lost, which is why I've removed network manager from my system. Though I hear it's not as bad as it was when I had to make this decision. Sorry, can't help you here. Possibly you can configure network manager to leave all tun/tap interfaces alone.

  • Yes unfortunately Cinnamon relies on Network Manager, which means i cannot remove it. I tried but it breaks the desktop environment.

Ive installed and configured the priunl vpn client same as i did on my other Ubuntu 16.04 machine. About 15 seconds after i make a connection it gets killed and I cannot figure out why.



syslog shows the interface being removed by ntpd

So far I have tried:




  • marking tun0 interface as unmanaged in network-manager configuration

  • stopping network-manager

  • forcing ntpd to ignore virtual interfaces by adding the -L parameter


So far nothing worked.



UPDATE
Removing network-manager completely breaks cinnamon so this is not an option, however I increased the log level for NM to DEBUG

So far I have tried:




  • marking tun0 interface as unmanaged in network-manager configuration

  • stopping network-manager

  • forcing ntpd to ignore virtual interfaces by adding the -L parameter


So far nothing worked.



UPDATE
Removing network-manager completely breaks cinnamon so this is not an option, however I increased the log level for NM to DEBUG

  • Tunnel starts up, but after 25 seconds, you get an interrupted system call (timeout?), followed by a SIGTERM (possibly as consequence). So the question is where this interrupted system call comes from, and what exactly is causing it. If you can run the priunl OpenVPN client somehow with more verbose logging enabled, that would help. If ntpd is interfering for some reason, stopping ntpd and trying without it is the obvious experiment.

  • By the looks of it it is network-manager thats stopping it. I cannot rmeove network manager because cinnamon depends on it

  • I have battled with network manager before, and lost, which is why I've removed network manager from my system. Though I hear it's not as bad as it was when I had to make this decision. Sorry, can't help you here. Possibly you can configure network manager to leave all tun/tap interfaces alone.

  • Yes unfortunately Cinnamon relies on Network Manager, which means i cannot remove it. I tried but it breaks the desktop environment.

            How to rewrite equation of hyperbola in standard form

            Image
            2 $begingroup$ I was wondering about this question: $$ 9 x ^ 2 -4y^2-72x=0 $$ What is the step-by-step process of writing such an equation which, in this case, has the graph of a hyperbola in standard form? Please excuse me for my messy equation. As I am relatively new to Mathematics Stack Exchange, I do not know how to insert superscripts. Thank you ahead of time! calculus conic-sections share | cite | improve this question edited 2 hours ago Key Flex 8,637 6 12 33 asked 2 hours ago

            No ethernet ip address in my vocore2

            Image
            0 I just flashed my vocore2u with openwrt 18.06.1, and plug it with an ethernet cable to access network while setting up wireless access-point for my phone. The AP is working and connected to the network, but the ip in my phone is in the subnet of another router. And there's no ip assigned to my vocore2 so I cannot ssh into it. After connecting to vocore2 with serial terminal, ping 8.8.8.8 is also failed. How can I make my vocore2 gain ip from the router and setting up the network well? root@OpenWrt:/etc/config# ifconfig apcli0 Link encap:Ethernet HWaddr BA:D8:12:07:01:71 inet6 addr: fe80::b8d8:12ff:fe07:171/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 erro
