## On OpenSuSE, when adding Apache vhosts with their own log files don’t forget to update your logrotate configuration

Posted by jpluimers on 2016/10/27

Sometimes you forget one crucial step…

When adding Apache vhosts on OpenSuSE and each vhost has it’s own set of log-files, then they will not be logrotated by default.

So you have to edit the configuration.

I’ve done it by copying the default apache2 logrotate configuration file for each vhost like this:

/etc/logrotate.d # cp apache2 apache2.vhost.##hostname##

Here ##hostname## is the name of the vhost.

Then I edited each file and replaced the generic log file names with the specific ones for each vhost.

There are only a few vhosts on my system so the manual job wasn’t so bad, but with a great number of vhosts you’d probably want to make this a template process beyond this:

function logrotate-add-apache2-vhost-file()
{
# $1 is the vhost name ## http://stackoverflow.com/questions/16790793/how-to-replace-strings-containing-slashes-with-sed/16790877#16790877 cat /etc/logrotate.d/apache2 | sed -r "s#/var/log/apache2/#/var/log/apache2/$1-#g" > /etc/logrotate.d/apache2.vhost.$1 git add /etc/logrotate.d/apache2.vhost.$1
}


This will then show in less what logrotate (which will output both to stderr and stdout, hence the 2>&1 redirect) would do on the next invocation:

logrotate -d /etc/logrotate.conf 2>&1 | less

## Only the KB2267602 updates (all others are fine) failing on Windows 8.1 with error 8007051A?

Posted by jpluimers on 2016/10/27

On a Windows 8.1 system, I’m having trouble installing KB2267602 [Definition Update for Windows Defender – KB2267602 (Definition 1.231.456.0)] as it throws error 8007051A each time even after reboots, shutdowns, re-tries and using different ISPs.

https://www.google.com/search?q=8007051A+KB2267602 didn’t get me any further.

On other Windows 8.1 systems this went fine (this one has Visual Studio 2015 installed) as were the Windows 7 installs of KB2310138 [Definition Update for Microsoft Security Essentials – KB2310138 (Definition 1.231.456.0)].

I’ve not tried manual downloads from https://www.microsoft.com/security/portal/definitions/adl.aspx [WayBack] yet: anyone tried that before?

## permissions – recursively change owner windows 7 – Super User

Posted by jpluimers on 2016/10/27

Slightly updated the answer the /D Y part will recursively accept taking ownership when directory listing is denied in the permissions:

To fix really broken permissions, the best is to run these two commands one after the other:

takeown /F /D Y "C:\path\to\folder" /R
icacls "C:\path\to\folder" /reset /T

The first one will give you ownership of all the files, however that might not be enough, for example if all the files have the read/write/exec permissions set to “deny”. You own the files but still cannot do anything with them.

In that case, run the second command, which will fix the broken permissions.

## OpenSuSE Tumbleweed: after installing from ISO, be sure to disable/remove the ISO repo

Posted by jpluimers on 2016/10/26

TL;DR: OpenSuSE Tumbleweed – after installing from ISO, be sure to disable/remove the ISO repo.

A while ago I had a weird thing on my OpenSuSE Tumbleweed system while upgrading (yes, zypper dist-upgrade is the recommended way to update Tumbleweed): it would complain in this way zypper dup indicates python3-urllib3-1.16-1.1.noarch requires python(abi) = 3.5:

# zypper dup
Warning: You are about to do a distribution upgrade with all enabled repositories. Make sure these repositories are compatible before you continue. See 'man zypper' for more information about this command.
Loading repository data...
Reading installed packages...
Computing distribution upgrade...

Problem: python3-urllib3-1.16-1.1.noarch requires python(abi) = 3.5, but this requirement cannot be provided
Solution 1: Following actions will be done:
deinstallation of python3-urllib3-1.15.1-2.1.noarch
deinstallation of python3-wheel-0.29.0-2.1.noarch
deinstallation of speedtest-cli-0.3.2-4.3.noarch
deinstallation of python3-six-1.10.0-4.1.noarch
deinstallation of python3-pycparser-2.14-2.1.noarch
deinstallation of python3-pyasn1-0.1.9-2.1.noarch
deinstallation of python3-pyOpenSSL-16.0.0-3.1.noarch
deinstallation of python3-idna-2.1-1.1.noarch
deinstallation of python3-chardet-2.3.0-1.4.noarch
Solution 2: keep obsolete python-cupshelpers-1.5.7-7.2.noarch
Solution 3: break python3-urllib3-1.16-1.1.noarch by ignoring some of its dependencies

Choose from above solutions by number or cancel [1/2/3/c] (c):


What eventually – with help from the excellent help by DimStar on the #openSUSE-factory IRC channel – led to the solution was the part Solution 2: keep obsolete python-cupshelpers-1.5.7-7.2.noarch.

But first let’s look at the installed versions and repos:
