Synology DS215j update results in read only access

Sun, 17 May 2015 20:40:00 +0200

Saturday morning I received a mail from my parents NAS (Synology DS215j) about a reboot after a system update. A few hours later my father called me, mentioning that he cannot write to the NAS anymore. All files are accessible in read only mode. All write operations under windows raises an error.

Installing ClearOS 6.5 with graphical UI on XenServer 6.2

Fri, 09 Jan 2015 15:08:00 +0100

XenServer provides several templates for different operation systems of its hosted virtual machines.

Unfortunately there is no template for ClearOS and so I tried some of the in my opinion best fitting templates.

Network settings for ClearOS in VirtualBox

Tue, 25 Nov 2014 19:37:00 +0100

ClearCenter offers an almost ready to go VirtualBox image:

http://www.clearfoundation.com/Software/downloads.html

With the first boot it provides a web based configuration GUI via URL

https://10.0.2.15:81/

Per default it is not possible to access this URL from the host machine which runs the VirtualBox virtualization software. So it is necessary to forward the request to the virtualized guest (ClearOS).

Replace or keep existing configuration files during Linux updates/upgrades

Thu, 20 Nov 2014 17:03:00 +0100

During updating/upgrading a fresh Moebius installation on a RaspberryPi with

apt-get update && apt-get upgrade

it brought this question:

Configuration file `/etc/issue'
==> Modified (by you or by a script) since installation.
==> Package distributor has shipped an updated version.
What would you like to do about it ? Your options are:
Y or I : install the package maintainer's version
N or O : keep your currently-installed version
D : show the differences between the versions
Z : start a shell to examine the situation
The default action is to keep your current version.
*** issue (Y/I/N/O/D/Z) [default=N] ?

The default hint not to do that is mainly for longer running installations to avoid an overwriting of existing configuration files. In case of a fresh installation you should confirm with Y.

Das geht ganz fix mit PsGetSid aus den PsTools von SysInternals.
