For instance, you might see wls1:, which probably indicates a Wi-Fi connection that you’re working with. You’ll be given a list of MAC address figures and you simply need to look for the name that GNU/Linux gives to your network adapter. So, here’s what to look for in a strong Linux VPN setup: Industry-leading security: The best VPNs use trusted VPN protocols like WireGuard®, OpenVPN, and IKEv2. As we mentioned above, not all VPNs are created equal. It is just a small header file and does most of the simple stuff you need without using a big template-based approach like boost(no offence, I like boost!). Method 1: Find MAC Address Numbers with ip link At the prompt, simply type ip link and push enter. When you have a list of possible Linux-compatible VPNs, it’s time to start looking at the core features. The whole code can be found at the bottom. I have spent most of yesterday writing the code, so I decided to describe it here. The information on the internet is not very good, and the process is quite complicated. Note that on AIX systems, the returned MAC address is not colon-separated (for example. Getting IP, IPv6 and MAC addresses on Linux is no easy task if you do not use ifconfig. There is an excellent answer from Shreevardhan below with this source code (This code may throw): #include įor (const auto & entry : fs::directory_iterator(path)) The getmacs command collects MAC address from a single or range of nodes. In C++17 there is now an official way to list files of your file system: std::filesystem.
