How to speed up DNS caching on Linux machines with dnsmasq by https://is.gd/xDKMgl

Chances are, you’re looking to squeeze out as much performance from your Linux servers and desktops as possible. This is especially so with regards to networking. With Linux, there are so many tweaks you can undertake to optimize a machine, it’s mind blowing.

One such tweak that can significantly decrease your DNS lookups is by adding dnsmasq into the mix.

Dnsmasq is a lightweight DHCP and DNS caching nameserver. Unlike BIND, dnsmasq is incredibly simple to get up and running. The benefits of adding this will be quite obvious (like your DNS queries getting dramatically faster).

That Nasty Samba Vulnerability Is Now Patched in All Supported Ubuntu Releases by https://is.gd/suMzeI

You might have read the news this morning about a wormable code-execution bug discovered in the Samba free software re-implementation of the SMB/CIFS networking protocol, which existed in Samba for more than 7 years.

The Samba team managed to quickly patch the critical vulnerability that was discovered to affect over a hundred thousand Linux and UNIX machines running Samba, which is usually used to provide file and printing sharing services, allowing users to connect to Windows shares on a network.

The Samba 4.6.4, 4.5.10 and 4.4.14 patched versions have been released, and are available for download from the official website or via ours if you want to compile it on your GNU/Linux distribution. Canonical already patched Samba in all supported Ubuntu releases, and other GNU/Linux distributions will soon receive the patch.

Firefox 54: more multi-process content processes by https://is.gd/7xLhyI

firefox-multiple-content-processes

Mozilla plans to increase the number of content processes of Firefox’s multi-process architecture to four (from one) with the release of Firefox 54.

Some Firefox installations are still not eligible for Firefox’s multi-process architecture. This includes systems with accessibility tools or settings enabled. Multiple processes won’t be enabled for users with extensions either, regardless of whether those are legacy add-ons, or WebExtensions.

Mozilla ran its memory test again to determine the right number of content processes. An increase in the number of content processes for the browser always goes along with an increase in memory usage.
