Authentication Monitor for Debian and Ubuntu 1

Feb

2013

What is Authentication Monitor? If you have a Linux server running Debian or Ubuntu and want to be notified when certain users gain access to one or more of your critical services (e.g. “ssh/sshd” and “proftpd”), then Authentication Monitor might be just what you’re looking for. Authentication Monitor runs silently in the background as a ...

“Connection failed”, when conneting to Avahi advertised Samba-service from OSX Finder 4

Jan

2012

If you own a Mac and have recently tried advertising a Samba-service/share (most likely from a computer running Linux or a NAS-server), you properly also ran into the same problems that I were having, when trying to connect to it from the OSX Finder. It seems the way that newer versions of OSX automatically discover ...

Linux 2.6.38 and VIA Chromotion HD 2.0 combination results in blank/black terminal

Dec

2011

At work, we use HP Thin Clients with a Debian distribution on top. We sometimes buy new hardware and when faced with discontinued models, we of course have to find new ones. Last time we decided on the HP t5550 Thin Client, which were to prove a bit of a challenge when we had to ...

How I Got “lm-sensors” Working on my Via Epia SN1800 Motherboard 1

May

2011

I’ve been the owner of a Via Epia SN1800 motherboard for quite some time now, and ever since I got it, I’ve always wanted to be able to monitor the CPU temperature from inside the operating system. Since I’m using Linux, this means using the “lm-sensors” program, which in my experience never seems to work ...

The contents of this article is only available/relevant in Danish. Jeg har netop skiftet fra Stofanet til Telenor Bredbånd. Jeg har egen mail-server kørende på min Internet forbindelse. Opsætningen på Stofanet’s netværk var lige til at gå til, da de har en fin vejledning på deres hjemmeside, som beskriver hvordan man gør. Men efter mit ...

iPhone Bluetooth Tethering in Ubuntu

Apr

2010

Ubuntu is, out of the box, pretty good at handling mobile Internet connections via bluetooth from various mobile devices. It even supports the iPhone to some extent. I’ve been using Ubuntu’s built in functions to access the Internet from my netbook via my iPhone for quite a while now, but I have never been completely ...

2010

Update on the 26th of December 2012: I would like to turn your attention towards the ownCloud project, which I recently started using myself as a replacement for the solution as described in this article. Not only does ownCloud provide you with easy access to user calendars, but also to contacts and file synchronization! (just ...

Ubuntu freezing on Via EPIA 10000 M 2

Jun

2009

I recently tried installing the latest version of Ubuntu on my Via EPIA 10000 M board, to use it as a Media Center. But I experienced some strange behavior. After about 30 to 60 minutes of use, my system completely locked up. All I could do to get the system back up, was perform a ...

Make ‘dd’ talk

Jun

2008

I’ve always felt frustrated when using the ‘dd’ program to clone harddisks. It does it’s job beautifully and I’ve come to use it somewhat regularly at work lately, but it’s a pain to have to sit around waiting for it to finish. You simply have no clue how long it’s going to take. If you’ve ...

Zend Studio 5.5: Blank main window

May

2008

I recently installed the latest version of Ubuntu. 8.04 Hardy at the time of writing. My computer had the previous “Gusty” release installed, so I merely tried to upgrade using the package manager. This resulted in a somewhat crippled configuration, where some parts of my system was not acting as it should. I had no ...

The SSH Crippling

Apr

2008

About a week ago, my Terminal application in Leopard suddenly started acting funny. I was trying to connect to my server back home to do some regular maintenance, and instead of the expected password-prompt, I was getting an error message I’ve never seen before. Also never on a UNIX box. The following output shows my ...

Pidgin: The missing SSL-protocol

Jun

2007

I just recently started using the new version of the Pidgin instant-messenger client, which recently changed it’s rather popular name from GAIM, due to some legal problems the GAIM team had been having with AOL. I downloaded the latest source files (at the time of writing the latest version was 2.0.1) from pidgin.im and got ...

The sleeping Debian console

Feb

2007

Here’s a way of altering, or completely disabling, a feature in Debian, causing the console-monitor to black out after 15 minutes with no user inputs. This is an old feature meant to prevent an image from being frozen solid into CRT monitors, leaving it somewhat obsolete to people using TFT monitors. The following line completely ...

How to mount a Samba share in a Linux/UNIX environment

Feb

2007

There are certain things I always forget. This is one of the things that has kept me starring at a blank UNIX terminal, a few times to many. So I decided to finally document the solution I always end up searching for. Mounting a Samba share on a Linux/UNIX system is pretty easy, but you ...

Fon: Mac connection problems

Jan

2007

I’ve just read on Fon’s community-sites that people with Mac computers (like myself), are having difficulties connecting to their Fon router’s private network. This problem is easily solved, by accessing the administration-panel of the Fon router and simply changing the encryption type from WPA1/2-Mixed-Mode (which OS X does not support), to a clean WPA1 or ...

How to avoid fsck prompts during the boot sequence

Jan

2007

I just found this wonderful word of advice, on a subject that has been bugging me for quite some time now, regarding the system disc on my Debian server. Write FSCKFIX=yes in /etc/default/rcS. You will not face the fsck problem from the next reboot onwards. However, if the disk is corrupted very badly, your presence ...
