Linux

We’re reviving a blog series from a few years ago in which we compile and share the things Cakti are clicking on — articles, videos, podcasts — whether it’s tech-related, an idea for social good, or just something interesting or amusing that caught someone’s eye. Have a look at this recommended reading and let us know what you think:

At Caktus we use LVM2 on a RAID1 device to ease disk management on a number of our servers. Recently I needed to downsize the root partition of one of the servers, so I rebooted onto an Ubuntu 8.10 LiveCD and attempted to load the RAID/LVM info.

At Caktus, we use the Asterisk open source telephony platform. While setting up Asterisk, we tested a number of different system environments and configurations to help determine what would best fit our telephone needs. This involved running Asterisk on both real and virtual machines and testing several configuration front ends, including FreePBX and DeStar. This article discusses a fairly technical problem we confronted while installing a basic Asterisk setup on the Debian GNU/Linux operating system (on real hardware); namely, when the ztdummy Linux kernel module was loaded, Asterisk was unable to play back any recordings (even its own). When we unloaded the ztdummy module, however, recordings would play back fine. The catch, of course, was that we needed ztdummy loaded for conference room support.
