Improving Linux networking performance [LWN.net] - https://lwn.net/Article...
"100Gb network adapters are coming, said Jesper Brouer in his talk at the LCA 2015 kernel miniconference (slides [PDF]). Driving such adapters at their full wire speed is going to be a significant challenge for the Linux kernel; meeting that challenge is the subject of his current and future work. The good news is that Linux networking has gotten quite a bit faster as a result — even if there are still problems to be solved." - imabonehead from Bookmarklet

"Talk for SCaLE13x: Profiling can show what your Linux kernel and appliacations are doing in detail, across all software stack layers. This talk shows how we are using Linux perf_events (aka "perf") and flame graphs at Netflix to understand CPU usage in detail, to optimize our cloud usage, solve performance issues, and identify regressions. This will be more than just an intro: profiling difficult targets, including Java and Node.js, will be covered, which includes ways to resolve JITed symbols and broken stacks. Included are the easy examples, the hard, and the cutting edge." - imabonehead from Bookmarklet

Poll - Impact of a switch to systemd for Debian Users https://framadate.org/shrov71... - A. T.
Is it new? I thought Debian has already been released with systemd. We've (Arch Linux users) been using it for almost 3 years, so good luck with changing that. ^^ FIGHT FIGHT FIGHT! (I like systemd.) - cek bauer
one thing is to have it available as choice, and completely different story is systemd pushed down throats as default and un-removable component of distro. - A. T.

Turla Trojan Unearthed on Linux | Software | LinuxInsider
"Turla, a hard-to-spot Trojan that has for years bedeviled Windows systems, has been discovered to have at least two Linux variants. Linux Turla maintains stealth without requiring elevated privileges while running arbitrary remote commands. The malware cannot be discovered using netstat, a command-line administrative tool, Kaspersky Lab said, and it uses techniques that don't require root access." - imabonehead from Bookmarklet

"Now that the root DNS servers are signed, I thought it was time I started using DNSSEC on my own PC. However, not wanting to wait for my ISP to enable it, I decided to setup a private recursive DNS resolver for myself using Unbound." - A. T. from Bookmarklet

Undound? Флудить? Как то вы очень неправильно его готовите, он вполне годный. - citrin
я неверно выразился. просто после suspend -> wakeup цикла на лаптопе через какое-то время пришлось перезапустить браузер. Он вроде не фетчит сами табы, но DNS requests делает. И таким макаром DNS умер. то есть совсем. глянул в трафик и понял что оно нарождало запросов по wakeup несколько сотен, то есть на каждый таб перезапущенного браузера... оказалось проще прибить, чем ждать пока оно само прочухается. - A.

"Barrelfish is a new research operating system being built from scratch and released by ETH Zurich in Switzerland, with assistance from Microsoft Research. We are exploring how to structure an OS for future multi- and many-core systems. We are motivated by two closely related trends in hardware design: first, the rapidly growing number of cores, which leads to a scalability challenge, and second, the increasing diversity in computer hardware, requiring the OS to manage and exploit heterogeneous hardware resources." - imabonehead from Bookmarklet
Barrelfish? From MSFT? GNU/Linux or open-source? :) - A. T.

"The Bash vulnerability known as Shellshock can be exploited via several attack surfaces including web applications, DHCP, SIP, and SMTP. With multiple proofs of concept (including Metasploit code) available in the public domain, this vulnerability is being heavily exploited." - imabonehead from Bookmarklet
"Most discussion of Shellshock attacks have focused on attacks on web apps. There has been relatively little discussion on on other surfaces like DHCP, SMTP, and CUPS. In this post, we’ll tackle Shellshock exploits over the DHCP protocol. These techniques could be used by an attacker to compromise more machines within the network." - imabonehead

Data Recovery Techniques on Linux | HowtoForge - Linux Howtos and Tutorials - http://www.howtoforge.com/data-re...
"Data stored in files has a table of contents which indicates the storage location for each file on the drive. When we remove or delete a file the file goes into the trash. Files removed using rm command can be easily recovered. Removal/Deletion of a file leads to the removal of only of the table of contents. This states that now the space from which the file is removed is ready for new data to be stored; so while in the case of new data having been written over that space the recovery of the old data becomes difficult. But, if there is no new data written there, we can still recover it. First, let's go through a few Dos and Don'ts ." - imabonehead from Bookmarklet

Firejail – A Security Sandbox for Mozilla Firefox | l3net – a layer 3 networking blog
"Firejail is a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications. The core technology behind Firejail is Linux Namespaces, a virtualization technology available in Linux kernel. It allows a process and all its descendants to have their own private view of the globally shared kernel resources, such as the network stack, process table, mount table, IPC space." - imabonehead from Bookmarklet

"uselessd (the useless daemon, or the daemon that uses less... depending on your viewpoint) is a project which aims to reduce systemd to a base initd, process supervisor and transactional dependency system, while minimizing intrusiveness and isolationism. Basically, it’s systemd with the superfluous stuff cut out, a (relatively) coherent idea of what it wants to be, support for non-glibc platforms and an approach that aims to minimize complicated design. uselessd is still in its early stages and it is not recommended for regular use or system integration, but nonetheless, below is what we have thus far." - imabonehead from Bookmarklet

"Linux distributions still ship with the assumption that they will be multi-user systems, meaning resource limits are set for a normal human doing day-to-day desktop work. For a high-performance system trying to serve thousands of concurrent network clients, these limits are far too low. If you have an online game or web app that’s pushing the envelope, these settings can help increase awesomeness." - imabonehead from Bookmarklet

Linux systems infiltrated and controlled in a DDoS botnet - http://www.net-security.org/secworl...
"Akamai Technologies is alerting enterprises to a high-risk threat of IptabLes and IptabLex infections on Linux systems. Malicious actors may use infected Linux systems to launch DDoS attacks against the entertainment industry and other verticals. The mass infestation of IptabLes and IptabLex seems to have been driven by a large number of Linux-based web servers being compromised, mainly by exploits of Apache Struts, Tomcat and Elasticsearch vulnerabilities." - imabonehead from Bookmarklet
