Relayd

another component of OpenBSD is relayd. it’s an integrated Loadbalancer & Proxy Service, like F5, Nginx and Others. But just like other BSD Services, straight, simple and easy to use … wanna see … ? Setup 4 VM’s, one Loadbalancer and 3 Webserver. The Webserver should server the same content, while the Loadbalancer checks if a Webserver is running and redirects traffic to the host or not. the configuration on the loadbalancer is simple like that:

FullBGP at Home

did you always wanted to have a fullbgp table at home once ? Over your DSL / CM / LTE or whatever connection ? here a little howto :) Setup VM Install a VM with OpenBSD. Add 1 CPU, 1 GB RAM, 20 GB Disk, nothing special Check our Upstream Provider Check the Page from Lukasz and spend him a Beer if you ever meet him. Edit your Config set the router-id to your Public IP.

Git Clear your History

Clear History have you ever checked in some binarys, confidential stuff or something else by mistake ? Git will keep all your history, that’s their design and purpose. how ever, if you need to cleanup once, here is a short tutorial. Kill Git Config cd myrepo cat .git/config -> note down the url rm -rf .git Create New Repo git init git add . git commit -m "Removed history, ..." Push Remote git remote add origin git@host/yourrepo <- URL you noted down above git push -u --force origin master All in One _url=$(git remote -v |awk '/fetch/ { print $2 }') rm -rf .

Serial Console & Ttys

assuming you have a apu2|apu3|apu4 from pcengines or a virtual machine running on KVM/Qemu. And you don’t have vga/dvi/hdmi whatever kind of video output. of course, you can install and run OpenBSD (or Linux) on this boxes. boot.conf if you wanna install from an USB Stick, set the correct Port and Speed before booting. boot> stty com0 115200 boot> set tty com0 or put these settings ins in the boot.conf on your tftp server.
