Nux!: Wasting time

http://www.nux.ro/archive/2015/04/Wasting_time.html

Quit twitter. Now if I could only do the same with reddit and hacker news. I might have a shot at doing something with my life. :). Later edit 7th May: well, that didn't last long, I reactivated my twitter account. But HN and Reddit remain banned. So, partial victory. Show the IP address. My RPM repositories for CentOS/(RH)EL. My CentOS based remixes. Linux templates and appliances for Cloudstack. Faith in humanity restored (1). Fuck this shit (6). Ghost in the shell (1). Scientific linux 6 (1).

Nux!: Protect KVM processes from OOM killer

http://www.nux.ro/archive/2015/07/Protect_KVM_processes_from_OOM_killer.html

Protect KVM processes from OOM killer. While running clouds on Linux KVM hypervisors it may happen that some of your virtual machines processes get killed by the OOM killer. In order to free up memory. Depending on your situation, the OOM killer may be instructed not to kill certain processes; but if you go this way make sure you know what you are doing. And how resources are used. So, to proceed with protecting KVM processes from out of memory scenarios, we need to run a few commands:. Echo '*/1 * * * *...

Cloudmin GPL for Linux KVM. The good people behind the Webmin project have released their free (as in beer and speech) version of Cloudmin with support for Linux KVM hypervisor. This is so cool. Can't wait to try it out! Http:/ webmin.com/cloudmin.html. Http:/ webmin.com/cinstall-kvm.html. Virtio drivers for FreeBSD. KVM is quickly becoming the de facto standard in virtualisation (dodge this, Vmware! And today to make the experience even better I stumbled upon binary virtio drivers for FreeBSD. More info...

Nux!: Setting up Varnish in a CentOS server

http://www.nux.ro/archive/2015/03/Setting_up_Varnish_in_a_CentOS_server.html

Setting up Varnish in a CentOS server. Is one of those small, shiny, remarcable jewels of the open source world. It can make an enormous difference in how your web application responds and how fast your web site loads. It's all in it's caching feature and not only; I've seen people use it as an web application firewall (search github) and out of the box it will only forward well formed HTTP requests to your backend, acting as a filter against malicious activity or scans against your server. 1 - Assuming ...

Nux!: "Fixing" Firefox

http://www.nux.ro/archive/2015/01/_Fixing__Firefox.html

For quite some time now Firefox has a shitty behaviour regarding the address bar, which may be OK for grandma, but it gets in the way of power users. I was too lazy to do anything about it until now, but it's 2015, I am getting old and less tolerant, so here are my pet peeves:. A - modify urls that do not look like traditional addresses and add a www prefix and .com suffix. B - send a single word address to a google search instead of opening it (kills internal addresses such as "http:/ wiki").

So you have BT Infinity, the white Openreach modem is up and running and you have broadband via wired or wifi through the fancy BT HomeHub; but you are a geek or a freak and you want to run your own router. You want to use your local linux box, custom dd-wrt router or who knows, perhaps a Raspberry PI. Fair enough. Here's how to do it:. 1 - disconnect the BT HomeHub router from the white modem. 2 - connect your linux machine to the modem (LAN1 port usually). 3 - run pppoe-setup. Show the IP address.
