I created a Textual TUI application to display Linux journal entries aside with system performance metrics from sysstat (sar) in 10 Minutes portions. You can then move back and forward in time to look if events and unusual stats correlate.

It's more than a year since I last posted on my little blog. But now I wrote about a topic I am really excited about:

https://sebastianmeisel.github.io/Ostseepinguin/IPv6PrefixDelegation.html

In this article, I’ll show you how to delegate IPv6 prefixes using systemd-networkd —complete with VLANs, Raspberry Pi routing, and automated configuration. IPv6 is awesome.

#ipv6 #networking #linux #raspberrypi #systemd

I created some code to reformat the output of ip --brief to look a bit cleaner (IMO).

You can find the code in https://github.com/SebastianMeisel/mybashrc .

#ip #ipv6 #bash #awk #cli
