Ansible and MacOS

leave a comment »

As of 2.0 ansible uses a few more file handles to manage its forks, OS X has a very low setting so if you want to use 15 or more forks you’ll need to raise the ulimit, like so

sudo launchctl limit maxfiles 1024 unlimited.

Or just any time you see a “Too many open files” error.

VMWare-Image (Ubuntu 8.04 LTS) Networkproblem

leave a comment »

Man freut sich, dass man eine fertige Ubuntu 8.04 LTS – VMWare-Image unter heruntergeladen und zum Laufen gekriegt hat. In meinem Fall habe ich leider die Netzwerkverbindung nicht zu Stande bekommen.

Um die Netzwerkverbindung zum Laufen zu bekommen, habe ich folgende Schritte unternommen:

  • installiere VMWare-Tool
  • sudo rm -rf /etc/udev/rules.d/70-persistent-net.rules
  • sudo reboot

Das wars dann…
