Advanced Linux - using TCP BBR

Advanced Linux - using TCP BBR

I've looked at BBR and it certainly looks like a great innovation in network performance. That said I only recommend its use right now by advanced Linux admins with a pressing need for the improved performance, and then only after serious load testing on non critical network links.
For everyone else I recommend you wait until it is integrated into your Linux distribution and the mainline kernel. That way you are not messing with your vendor's highly tuned and optimized kernel configuration and you're getting something tested and integrated into the system as a whole.

Network bonding with Linux

Network bonding with Linux

Sysadmins have been using this trick for years to get their own, inexpensive, custom, high speed network links. A primary example is from a server to a NAS device. Or a server to a backplane switch that supports bonding.
These days there are even ways to bond ISP connections to increase bandwidth if you're lucky enough to have an ISP that supports bonding.

So read on and find out how to do network bonding on Linux.

Permanently mounting a Windows share from Linux

Permanently mounting a Windows share from Linux

If you're like most Linux users, you work in a mixed platform environment that likely includes Windows systems. Linux is quite capable of interacting with Windows systems and mounting Windows network shares on the fly. However, if you want to setup a particular Windows share to be always mounted at boot, here's a basic, generic tutorial. Keep in mind that this is a simple tutorial based on command line file editing that should work on most Linux systems. Please note that many Linux distributions have their own, often simpler, methods of performing this task so be sure to RTFM before using this method.

Limiting bandwidth hogs by application rather than by user in Linux

Limiting bandwidth hogs by application rather than by user in Linux

There are a lot of ways to do this, but Trickle does give a fairly simple way to limit applications on the fly (or globally). Unlike more traditional methods like IPtables or bandwidthd etc., this is a quick, easy, and (unless you want it to be) non permenant solution to using applications that normally hog bandwidth while allowing other applications to function smoothly. For example, downloading a big file without disrupting your YouTube cats viewing session.

Note that this article isn't for everyone. The author uses a long demonstration format to teach the concepts. Setting up ncftp and testing it before and after. But you can skim through and pickup the concepts easily enough.
My other issue with the article is the subtle backdoor Mormon Church advertising, but you can easily ignore that by just not watching the sample video.
