I need to remind myself of running the IPP webpage in compatiblity mode in IE11 to install printers.
Even if you specify
ipp.FQDN, IE11 will kindly enter your
FQDN into the list of domain names to show in compatibility mode. Remember to remove
FQDN from that list when you’re done.
iPrint client 5.99 seems to be the last of its kind. From now on, iPrint is an appliance. Maybe it’s time to leave Novell and their products for good.
Sometimes security is on the border of being ridiculous. Modern Windows 10 is very anxious when connecting to guest-access allowed, readonly Samba shares, Here’s how to allow “insecure” guest logons for stand-alone computers. The same is true when configuring a GPO.
If technologists do not speak up to educate policymakers, bad policy will result, and we will have to live with it.

It’s winter break, giving me time to bring systems down for their much needed maintenance. One of my tasks was to upgrade our XenServers. They’re not joined to the same pool for historical reasons. One of them is close to 8 years old, the other one is fairly new. For the first server I chose to reboot into the hypervisor after upgrading to 7.2, before upgrading to 7.3. A wise choice. Just for the fun of it, I chose not to reboot into the hypervisor on the second server between 7.2 and 7.3. This left me with the choice of restoring the old 7.1 version or performing a clean reinstall of 7.3. Neither option was inviting, so I had to reboot into the hypervisor prior to upgrading to 7.3. Lesson learned.
The irony of this story is that XenServer 7.4 was released two days ago. Luckily, I can use the new update feature and save me a trip to the server room.
While trying to log in on our Novell servers using Client for OES 2 SP4 IR7a on Windows 10 1709, I was greeted with:
A required network service has not started.
Please check your error log for details.
The third reply of this post gave me a clue, simply run
setup.exe one more time and reboot.
Uninstallation of IR7a still gives me error
0x80070005. The Registry settings in
HKEY_LOCAL_MACHINE\SOFTWARE\Novell was accessible to me as a regular user. Maybe the client’s uninstaller is complaining about rights in the filesystem.
iobit‘s uninstaller free saved the day.
I really wish for more specific error messages.
yourscript.cmd from an elevated Command Prompt window eliminated all my problems. Search for “Command Prompt” on the start menu and hold down Ctrl+Shift when you click on the menu item. Simply right-clicking on
yourscript.cmd and selecting “Run as administrator” proved to be insufficient. Creating
HKEY_LOCAL_MACHINE\SOFTWARE\Novell manually might also set things straight.
I’m experimenting further with
ports-mgmt/synth. I let
synth create some packages for me and I then removed all installed packages, save the
pkg package manager.
What a surprise I got when attempting to add my own metaport! Continue reading

r460621 added flavours to
editors/emacs. If you previously used
editors/emacs-nox11 to get a flavour suitable for most server systems, you’re in for a couple of surprises. Continue reading GNU Emacs flavours in FreeBSD
Those who decide about the software to use won’t be the ones who have to use that software.
