ZNC: install and configure an IRC bouncer

19 April 2014 in Debian, Hi-Tech, Linux

I recently needed to install an IRC bouncer as I was fed up to launch every say a ssh to connect to an external server, on which I had a tmux running a weechat to get IRC history. 2 problems here: Sometimes, I forgot to connect on it and missed some messages It was not integrated to Pidgin (what I use for any IM protocol) So I decided to setup a bounce IRC with ZNC!

NAXSI: Add security to your Nginx

15 April 2014 in Debian, Hi-Tech, Linux, Security

NAXSI means Nginx Anti Xss & Sql Injection. Technically, it is a third party nginx module, available as a package for many UNIX-like platforms. This module, by default, reads a small subset of simple rules (naxsi_core.rules) containing 99% of known patterns involved in websites vulnerabilities. For example, ‘< ‘, ‘|’ or ‘drop’ are not supposed to be part of a URI. It’s been a while that I wanted to test NAXSI and it seams working not so bad.

Ceph: why don’t you try Ceph and stop disks array?

11 April 2014 in Ceph, Debian, Hi-Tech, Linux

In France, we have the chance to have an ISP/Mobile Telephony provider called Free. They considerably reduced the market price for the Mobile phone communications in 2012. This was very fine for competition and for French people. Now we can have correct prices for Internet and cell phone data. Thanks to Free. Ceph is quite the same as Free but for storage systems. Since many years, disks array constructors sold us locked solutions with a very high cost of hardware and licenses’ software.

I finally switched from Awesome to i3

7 April 2014 in Debian, Hi-Tech, Linux

Yes once again and for a long time now I think, I moved to i3. It does not make so many thing than Awesome, however working on multiple screen with it, it’s better. That’s why I wanted to make a new test with it and it’s now adopted. I spent a little bit time on reconfiguring all my needs (workspaces depending my screen configuration, opening app on a defined workspace, keyboard bindings etc…).

28 March 2014 in Debian, Hi-Tech, Linux, Red Hat

Some of you will tell me that most utility is doing it as well. And that’s right, but with ccze you will be able to colorize everything with a pipe. For example when you play with a verbose service like Pacemaker, you need to get colorization if you want to win time. Here is an example: tail -f /var/log/syslog | ccze -A
