iSCSI

Just some experiments I made with iSCSI. If you want to use iSCSI in a productive environment, make sure to set up a dedicated network for your iSCSI traffic. And maybe don't use your wireless network for iSCSI. This article covers the following topics:

  • Basic Setup
  • Reduce access to a specific IP
  • Incoming user from Initiator to Target
  • Add initiator name for access control
  • Automatic lun import on startup

NanoPi Duo2 with IoT-Box & GSM/GPRS modem in Armbian

For a longer time I own the NanoPi Duo2 from FriendlyARM including the IoT-Box Carrier Board. The specs of the NanoPi Duo2 and IoT-Box are as follows:

NanoPi Duo2:

  • CPU: Allwinner H3, Quad-core Cortex-A7 Up to 1.2GHz
  • DDR3 RAM: 512M
  • Connectivity: 10/100M Ethernet
  • WiFi: 802.11b/g/n
  • Bluetooth: Bluetooth V4.0 of 1, 2 and 3 Mbps.
  • Camera: OV5640
  • ...

IoT-Box Carrier Board:

  • Onboard quad-band GSM/GPRS module
  • 2 x USB Host
  • Serial port and Ethernet port
  • Audio input and output
  • MicroUSB power input and a power switch
  • IPX to SMA WiFi converter


A lot of features are not accessable from the board itself like the ethernet port. One of the reason I also bought the IoT-Box. Another nice feature of the IoT-Box is the GSM/GPRS module (SIM800C), which will be the main focus of this article.

bacula: cannot restore without a bootstrap file

After a long time I decided to install and work with bacula again. After installation, configuration and running some jobs, I tried to restore a backup from the night. The result was the following:

...
05-Nov 07:56 bacula-dir JobId 11: Fatal error: Cannot restore without a bootstrap file.
You probably ran a restore job directly. All restore jobs must be run using the restore command.

Convert CDI to ISO

Today I was confronted with an "rare" format for CD images: CDI
Of course I needed the content from that disc but CDI is not really supported under linux and burning a small CD image for just copying some files one time was no option. So I searched a little on the internet how to deal with CDI files under linux. With iat I found a little neat program to convert CDI to ISO files. Under Armbian it has to be installed first:

dreamcast.local VIII - Skies Of Arcadia

A couple of days a new/old game arrived - Skies Of Arcadia! When the game came out, I never had a chance to play it. So I bought a copy and when it arrives, the first thing that cought my eye was the cover which states: "onlinefunctions". The offered online functions are limited to the official website. I couldn't find a copy of the website but some downladable content, so let's get the downloadable content running again with the Dreamcast server project!
