So I wanted to split a 3840×1080 wallpaper in two halves for my dual monitor based KDE 4.10.5 setup. Obviously there are several applications that would do the job, but why bother when ImageMagick can do it with a one-liner. The “magick” is achieved by using a geometry argument:
When using a client other than Skype for Business (formerly known as Lync) to connect with your Office 365 account, you’ll need to provide the Microsoft Lync servers with a user-agent string they recognize as an “acceptable” client. The reasoning behind this is surely to give you the best possible experience and not at all to lock out other messaging clients.
Just for the record: collecting failed logins from Logwatch and feeding them to the firewall is by no means a viable strategy against brute force attacks or other intrusion attempts. There are better means to mitigate these kind of security concerns in real time.
The Windows Update service will provide you with drivers for the Asus USB-N13 adapter, but in my experience, none of these drivers function reliably. They all suffer from the “limited connection disease” thus forcing me to reattach the dongle and play an endless game of connect and disconnect.
The message in question as shown below made its appearance while I was trying to shut down my laptop. The job went on for about a minute before completing its task.
Recently, I became aware that Apache’s access and error_log on a BlueOnyx 5107R server were both zero byte files. Restarting Apache to correct the issue resulted in the following error message:
(98) Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

The shadow.service unit reported that it had failed and threw the following error message: “user ‘colord’: directory ‘/var/lib/colord’ does not exist”. I had no recollection of housing such a user, but by issuing the command below there was hard proof (image to the right) that colord was indeed a homeless user on my system, and her home was supposed to have been /var/lib/colord.
Remember that old saying: if you don’t know the source, don’t click it? With all these new URL shortening services, that advice seems to have been thrown out the window. As a result, evildoers are embracing the technology to disguise their malware sites behind shortened URLs.
This is obviously effective as an URL like hxxps://goo.gl/3BSi65 would have a much easier time getting past your spamfilter than say something like hxxp://h4x0r.tld/inject.aspx
Excited by the prospect of hosting my blog on the new Raspberry Pi 2, I decided lately to wave goodbye to the local datacenter and unleash a Slackware Linux box into the wild (full story here).
Everything went (mostly) without a hitch until I wanted to get back in sync with the Slackware-current tree. After applying the available updates and issuing a reboot, the system seemed operational and nothing from the logs gave any indication of imminent failure.
Two weeks ago, I decided to move this blog from its old hosting and deploy it on a Raspberry Pi 2. The geek in me could no longer resist the urge to discover if a $35 worth computer could replace the need for commercial hosting. Besides, what a great opportunity to finally get my hands on Slackware’s official ARM port.
After Windows 8.1 had performed an unscheduled reboot, I was greeted with the following error message when trying to start up a virtual machine in VMware Player:
This virtual machine appears to be in use.
If this virtual machine is not in use, press the “Take Ownership” button to obtain ownership of it. Otherwise, press the “Cancel” button to avoid damaging it.
Trying to start the game Kane & Lynch: Dead Men from the Steam client on a default Windows 8.1 installation will not work. Furthermore, you’ll get no error message other than the obvious lack of the gameplay.
With the release of OTRS Help Desk 4, it seems that running OTRS on a native Windows environment for all intents and purposes is no longer viable. By killing off the Windows installer and recommending migration into the OTRS appliance, the OTRS Group seems to be subtly hinting that OTRS on Windows is dead in the water.
No additional software is required on a full Slackware 14.1 install.
Slackware 14.1 ships with KDE 4.10.5.
A while back I did some consulting work for a small ISP who had received complaints from a few customers that believed they could not use the ISP’s SMTP server to send email to outlook.com or hotmail.com accounts. These customers claimed they never got any bounce message (Non-Delivery Report) in return, so they firmly believed the problem resided with the ISP.
IPredator is a swedish VPN service offered with the stated goal of providing internet privacy.
BlueOnyx uses the PAM ABL module to mitigate brute force attacks. Though it’s not a good idea to rely solely on this module to protect your services, it’s definitely better than nothing. However, for some reason the database storing the failed hosts and users tends to corrupt easily on BlueOnyx systems.
This installation procedure will extract only relevant libraries and executables from the BIND 9 package, and not install a full-blown DNS server. The installation method is also applicable on Windows 7 64-bit systems.
Instead of logging on to each of your external email accounts, you can retrieve all your accounts’ email messages directly from Zimbra. It’s one of those things you just expect to work with an enterprise ready solution like Zimbra.
