![]() ![]() Similar to the 16.04.6 point release, 16.04.7 is a security-targeted release for the purpose of providing updated installation media which protects new installations from the recently discovered GRUB. The systems were based around an Intel Core i7 6800K, Core i7 8700K, Core i9 7980XE, dual Xeon Gold 6138, AMD EPYC 7601, and AMD Ryzen 7 2700X. Ubuntu 16.04 LTS ‘Xenial Xerus’ transitions into the extended security maintenance (ESM) support phase at the end of April 2021 from its standard, five-year maintenance window for Ubuntu long term support (LTS) releases. The Ubuntu team announces the release of Ubuntu 16.04.7 LTS (Long-Term Support) for its Desktop and Server products, and the Ubuntu Kylin flavor. The six systems were all comprised of different hardware and not intended to compare the performance between the systems but rather a look at how each system does when going from Ubuntu 16.04 Xenial Xerus to the Ubuntu 18.04 Bionic Beaver. Ubuntu 18.04 LTS has the Linux 4.15 kernel, GNOME Shell 3.29.1, Mesa 18.0-rc5, GCC 7.3.0, Python 2.7.15rc1, Python 3.6.5, and is mitigated for Meltdown with KPTI while for Spectre V1 it opts for _user pointer sanitization over OSB and for Spectre V2 has full Retpolines. ![]() In some past articles I've done some things like looking at the Ubuntu 12.04 to 18.04 performance while this article is just comparing the new/old Ubuntu LTS releases on six different systems for looking overall at how the Ubuntu Linux performance has evolved in the past two years.Īs a refresher, Ubuntu 16.04 LTS with all available stable release updates has the Linux 4.13 kernel, Unity 7.4.5, Mesa 17.2.8, GCC 5.4.0, Python 2.7.12, Python 3.5.2, and is mitigated for Meltdown/Spectre with KPTI, OSB barriers, and full Retpolines. Enable Wake on LAN in /etc/network/interfaces when static network configuration is used. Add NETDOWNno in /etc/default/halt to prevent powering off the network card during shutdown. Your server that is 'sleeping' does not have an. Basically, you ssh into a system on the same local network as your server to wake and use the MAC address to wake it. Is there a way to run this command without sudo I need to do so in order to run the command in a php script. However, It only works if I use sudo: sudo wakeonlan xx:xx:xx:xx:xx:xx When I don't use sudo the output says the magic packet has sent, but the server never wakes up. Continuing on with our benchmarking of the recently released Ubuntu 18.04 LTS, here are some reference benchmarks on a total of six systems with AMD and Intel hardware while looking to see how the out-of-the-box performance compares to the previous Long Term Support release, Ubuntu 16.04. In Ubuntu 16.04 set WOLDISABLEN in /etc/default/tlp to avoid getting WOL disabled by TLP power management. You need to have access to at least one computer (or router) on the LAN, and send the wake-up arp package from that. I'm trying to use wakeonlan to send a magic packet. ![]()
