XenServer, like many other bare-metal hypervisors, only supports a small bunch of RAID controllers. The difference between it and for example VMware ESXi is that XenServer is pretty much a CentOS minimal install with some proprietary administration tools and a pretty decent remote manager (only for Windows as long as I know…) while ESXi is a completely proprietary closed source blob. XenServer being based on CentOS makes it possible to do many weird unsupported things, like installing it on a software fake RAID on ICH8R.
Let’s say we have a big single FLAC file we want to split into multiple files, we are on Fedora and we don’t want to use anything but the command line. First of all: [root@fedora ~]$ yum install lame ffmpeg shntool cuetools To split the single FLAC file run: [user@fedora ~]$ shnsplit -o flac -f file_name.cue -t "%n - %p - %t" file_name.flac This will produce n single files, “-t” parameter is used to specify file name format (in this case: track_number – performer – track_name).
One year ago or so I wrote about my experience using the Logitech G500 on Linux, I like the mouse a lot, especially the scroll wheel, but there were also a couple of issues I couldn’t live with: 1. no driver for Linux, tuning DPI settings is a real PITA; 2. the fucker doesn’t track on close to every surface, be it a gadget mousepad you got for free at a meeting, a wooden table, a plastic-something table or a 20 € mousepad.
Long story short: in Fedora 20 (and as far as I remember also 19 and 18) XScreenSaver doesn’t power off the monitor backlight when locking the screen. Being the lazy ass I am it took like me 2 or 3 years to find the motivation to solve the issue. It was actually pretty simple, no need to edit some obscure config file or else, in XFCE just click on: Application menu -> Settings -> Screensaver.
Being the tinfoil hat I am I obviously don’t like nor use whatsapp, some time ago I set up my own XMPP server and made a bunch of close friends switch to it. There are multiple clients for every platform, my personal preference goes to Xabber on Android and Pidgin on GNU/Linux; both support OTR encryption and all around are pretty decent clients. The only real issue we had so far is the very annoying problem of lost messages; if the internet connection is stable and decent the problem will very likely never come up, too bad that mobile phone internet connection is everything but stable.
Ok, -everyone- knows it, this new version introduces a number of interesting updates, one above all: openssl version 1.0.1. Openssl is the library used by many programs to perform encryption tasks, for example it’s used by openssh, webservers, etc etc. The version included in CentOS 6.4 was really outdated, it doesn’t support TLS v1.2 for example, so I had to install it separately (which is a PITA to say the least).
It’s been quite a while since the last time I fired up the single stage (actually, it should be 290 days), let alone having a LN2 session. Past saturday I went to my grandfather’s place and got him a new PC since his precedent one is, to say the least, outdated. Anyway, since the old one has some interesting parts I decided to give it a try, hooked it to the single stage and baaaaaaam.
This post is meant to be the sequel of the one I wrote one month ago about CentOS as router, transparent proxy, and much more. A big chunk of the precedent article is on how configure squid and squidGuard to act as a transparent proxy with URLs filtering capabilities. But there’s a problem with that: nowadays many sites (f4c3b00k.c0m just to name the most annoying one) are HTTPS. With HTTP one can really easily intercept a packet and read the payload (which contains the URL) but with HTTPS this is not possible anymore since the payload is encrypted.
I got a new TV for the living room (a Panasonic Viera TX-L39E6E) which is DLNA capable. To be honest I’m also planning to build some kind of media center, maybe a really low power one, based on some kind of raspeberry-pi lookalike device. Anyway, for now I’m using my workstation (Fedora 19 x86_64) to stream video contents using miniDLNA. First of all, let’s install it with the usual: $ sudo yum install minidlna Then, edit the following file:
As usual, long story short: I’ve to setup a firewall to log traffic, block some stuff and do some other things. – epel repo is required – The system is made of a single CentOS machine with 2 physical network adapters: 1. eth0, connected to WAN, static IP address 192.168.0.3 2. eth1, connected to LAN, static IP address 10.0.0.1⁄24 .:.
