A few months ago, I came across PassBolt.


Currently at work we’re using TeamPass, but we feel
it’s not that usable.
PassBolt uses Open Source technology such as GnuPG, CakePHP, OpenSSL and other software.

Currently, the demo is rather basic as a lot of functionality is still to be built.
But even when that’s the case, the interface looks clean and fresh ; the experience smooth.
Have a look at their roadmap, and see why this really could become a gem!

I use my smartphone regularly to login on servers of mine with SSH. This works really well, but obviously you have less width than with a normal computer screen.

Some tools, like w, will not work with this limited width and give you a message like 

w: 60 column window is too narrow

Being a sysadmin, I don’t like to be told something just can’t work. So, a little trick to make it work:

 w | cat

This will have w output it’s text through stdout to cat and cat just outputs the text to the console, no questions asked.

Yesterday I have installed Ubuntu 16.04 LTS on my laptop to try it out.
While overall the experience is quite good, I found that notifications were broken for apps like slack and atom.
Following the issue found on github, I have found the following workaround to work for me:

Add the following line to /etc/environment ( edit as root ) and reboot ( or logout and login )


Here’s how I managed to install the memcached module for php 7.0 running on a server running CentOS with DirectAdmin.

Install the remi repo and install the latest version of memcached and libmemcached

yum -y install http://rpms.remirepo.net/enterprise/remi-release-$(awk -F 'release ' '{print $2}' /etc/system-release| head -c 1).rpm
yum --enablerepo remi install memcached libmemcached-last libmemcached-last-devel git

Now configure and install the memcached extension:

cd ~
git clone https://github.com/php-memcached-dev/php-memcached.git
cd php-memcached
git checkout php7
./configure --disable-memcached-sasl --with-php-config=/usr/local/php70/bin/php-config
sudo make install

Add the extension to the php config:

echo "extension=memcached.so" | sudo tee /usr/local/php70/lib/php.conf.d/60-memcached.ini

And finally, restart php-fpm:

service php-fpm70 restart

Or if you run mod_php:

service httpd restart

I have a system running several docker containers with httpd, mariadb and redis. The httpd containers are running with names like ‘site1tld_httpd_1’.
Each httpd container writes the access_log and error_log to a host volume in /srv/volumes/<vhost>/httpd/logs . Just easy to have them accessible.

For these containers, I needed to run logrotate to keep those files from getting too large. Of course, these docker containers just run httpd as pid 1 and do not have logrotate installed.
The solution for me was to have logrotate on the host rotate every log, and then reload every docker container running httpd. A httpd reload is just done by sending a kill signal 1 to the httpd process.

This is done as follows ( a file in /etc/logrotate.d ):

/srv/volumes/*/httpd/logs/*log {
  rotate 7
    docker ps -f name=httpd -q | xargs docker kill -s 1 >/dev/null 2>&1

So the postrotate section is simple but effective: give me the ids of docker containers with “httpd” in the name and feed those ids to docker kill and use signal 1 to notify each process.


Vanavond “The Martian” gekeken.

Erg goede film. Redelijk trouw aan het boek, redelijk trouw aan de realiteit.

Hoe het ruimteschip wordt weergegeven is zoals het in mijn ogen in werkelijkheid zou kunnen zijn. Zwaartekracht wordt nagebootst door een soort wiel met leefcabines rond te laten draaien. ( Centripetale en centrifugale kracht, zie link )

Ook mooi dat de commandant op het ruimteschip, zoals in het boek, een vrouw is. De ongelijkheid die op veel plaatsen bestaat ( Gillian Anderson die in eerste instantie de helft van het salaris vam David Duchovny kreeg aangeboden de nieuwe X-Files serie, om in de filmwereld te blijven ) zal hopelijk verdwijnen in de toekomst.

Wel blijft de film, zoals vaak, een summiere samenvatting van het boek. Op sommige plekken afwijkend, op veel plekken incompleet. De humor van Watney ( de hoofdpersoon ) vind je niet terug en je leeft veel minder mee dan in het boek.

En dus mijn tip: lees het boek!



I have Fedora 23 Cinnamon Spin running on my laptop, which is great, I think.
But I like to have my system language set to English, while I prefer the rest of the locale ( time and currency formats for example ) to
be set to Dutch ( I want 24 hours clock and the euro as currency ).

In this spin, I just could only change the language, not the individual locale settings, but I’ve found out how to fix this.

Just enter
gsettings set org.gnome.system.locale region nl_NL.utf8
( Or any other locale, really ) to change this for your user.
