SSH login without password?

If you need to manage multiple servers, having to re-enter your password each time you want to establish an SSH connection can become tedious. There is a better way. It is possible to initiate an SSH connection by using a public/private key pair instead. The main advantage is that you can use this key on multiple accounts and only need to remember the pass-phrase of your key.

Recording voice prompts with Audacity and SOX

Asterisk comes with an extensive set of voice prompts in many languages but there are situations where you may need to record your own voice prompts. It can be tricky to get it right. This article describes the method I use to achieve that. I use Audacity and SOX to record and convert the voice prompt files.

It also manage the recordings. I did not build a custom case for this project, i bought it off the shelf (iStarUSA D-118V2-ITX 1U rackmount case) but i made some modifications to it.

Asterisk PBX

This is my Asterisk telephony server (PBX). It consists of a SBC board (PcEngine ALIX 2d2) and a FXS/FXO board (Openvox A400M with 2 FXS and 1 FXO modules). The alix2d2 has a Geode LX800 processor at 500 Mhz and 256 MB of memory. Not particularly fast, but enough for the job. I needed it to be a very low power system (under 10 watts) since it has to run 24/7.

HTPC (home theater pc)

This is my HTPC. At first, it was supposed to be a PVR. I wanted to add a TV tuner, but i dropped the idea and instead, built a separate media server for this purpose. Now it only serve as a “frontend”.

I did not buy a ready-made case for this project, i took an old Scientific Atlanta Explorer 2000 and modified it to fit a mini-itx board.
