I am installing openvpn on Ubuntu 18.04. The installation and setup goes smoothly. I start the systemd service and it succeeds. But, there is no tun0 interface in ip a.



If I reboot, then tun0 is there.



I tried modprobe tun before rebooting but that didn't change anything.



What does tun0 need to appear without a reboot?






systemd openvpn

    Enabling and starting a service is not the same. All enabling does is making sure the service is started on every boot. Just start the service (replace "enable" with "start") and tun0 should appear.

    Please post more information to allow us to troubleshoot this. For instance, output of systemctl status openvpn.service (or whatever the exact service name you're starting is), perhaps some lines from journalctl -e that you think might be relevant, snippets from ip a, lsmod, etc. You need to provide more information in your question to get an useful answer to it. Thanks!

    To add to what @FilipeBrandenburger said: There's no way the start of the service is successful if tun0 doesn't appear.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
