Google’s verification annoyance is nightmarish on Evolution 3.26.6 (3.26.6-1.fc27) that I still want to use, because it works like a charm with an Exchange server I was recently pushed into, with GPG, and with almost anything else you throw at it. Evolution is great, and has been for a long time now.
Yet a recent “feature” in GMail has been dramatic at first, preventing me to add my GMail accounts at all, until I had figured out I should turn off Google’s OAuth2 login in Account Settings, and set it to password and login for imaps and ssmtp respectively.
This leaves me with usable Evolution for GMail accounts, albeit I have to turn the annoying pop-up “feature” off every time I start the client.
Due to the way that NRPE/Nagios reads output from this fine plugin, it will show only the first running container in the Web-interface if asked for check_docker –status running. Python solves “printf” functionality by adding a suffix, so here’s a quick diff for the plugin so it can display all of the running containers when asked by check_docker plugin:

I had a rough time with Docker’s messages saying “connectivity on endpoint” (AKA “your port is already used by something else”) messages a few hours ago. The log on the upgraded Ubuntu looked somewhat like:

I thought the upgrade from 14.04 LTS to 16.04 LTS did it, because it was a hell of its own kind, but apparently everything was there, and the forums weren’t clear enough.
It ended up to be my tainted /etc/networks/interfaces file, where my aliased IPs wouldn’t start normally for a reason still unknown to me. I did rewrite those aliases in order to make sure it was tidy, but it wouldn’t start normally until I moved those aliases of an interface directly beneath the “auto p4p3…” directive for the parent interface.
As soon as I cleared those, the next reboot again took only 20-ish seconds, and the docker containers started as expected.
New Confluence 5.9.7 is now available to the members of the appropriate groups in LDAP. There was an issue with Confluence-in-Docker in the installation phase where Confluence would reach the “Insert license key” step, and then simply spin in a vicious circle.
Found a workaround for that – simply do not attempt to add SSL keys to Confluence during the installation, but reach it through an openssh tunnel (make sure you reach it as “127.0.0.1”) finish the installation, and then add SLL, LDAP and other necessities.
The jenkins.simulakrum.org server is now running from within a Docker container. Migration was flawless and done from scratch in less than 30 minutes. The reason was that Ubuntu would fail to restart a native jenkins service if another Docker container would use a port, albeit on a different IP. After being fed up with constant joggling between solutions for that, I decided it would be faster to simply “dockerise” Jenkins, too, and have it confined in a container for good. Continue reading →
Had to move 389-ds from a docker container running under a CentOS 7 to docker container running under Ubuntu 14.04 LTS. An exotic message appeared once I tried to run the dirsrv from within the new container:
