some basic commands for branches. you can read Branch Basics and Branch Management for more details
you wanna develope a feature, fix a bug, test some stuff … you need a branch !
git checkout -b feature1
if you have a central repo, push the feature upstream (so others can checkout as well)
git push --set-upstream origin feature1
you may have multiple branches, list them all. and update pager so list will not open in VIM !
i like to run honeypots … ok, to be honest, it’s not a honeypot. It’s a productive maschine for me, but all the bots trying to get in get’s redirected to a Honeypot, the credentials were captured and last but not least, you can watch them live in your browser :)
btw. 100k failed login attempts in 10 Day …
have fun !

This is similar to the previous Post, but with a small difference.
Here, we add an other Partition /jail with 2GB Size. On this Partition, we remove the nodev & nosuid Flag, so we can use this Partition as Root for some Jailed Users. And last but not least, we fireup a new VM, configure a Jailed User and make it Public Available …

you may want to manage some vm in the cloud. webgui is nice, but a real nerd needs cli ;)

As the hcloud is not available for OpenBSD, we have to build it on our own.
It’s always good to have Templates. Isn’t it ? Sometime, with a lot of stuff preconfigured and installed. Sometimes, a fresh install without anything (except syspatches). Here a little Helper, how to Build a OpenBSD Template with 20GB, resp. 40GB Disk Size.
This stuff was tested on www.hetzner.de, so you should be able to reproduce it in a few minutes.
Costs: CX11, 1 CPU, 2 GB RAM, 20 GB Disk, 20TB Traffic -> 2.68 Euro/Month
Costs: CPX11, 2 CPU, 2 GB RAM, 40 GB Disk, 20TB Traffic -> 3.76 Euro/Month

you may know what RPKI is …
It’s a PKI Framework for improving Security for the Internet Routing Infrastructure based on BGP.
As a HomeUser or Small/Medium Size Company, you normally don’t have a Full BGP Table and multipe Upstream Providers. You have one Internet Router or Firewall and you get a Default Route from your ISP.
With OpenBGPD and the current rpki extensions, you “just” need a Full BGP Feed and then, you can filter all invalid ROA’s and keep your Routing (and Internet Access) more Secure.
