#sysadmins — Public Fediverse posts

In the beginning, there was #TTY and serial ports, and verily did #sysadmins have text-based console access to fix a server falling over. And it was good. Not efficient, and scaled poorly, but for the 80s, it was good.

Then came addon boards and it was…ok. Then upon the world did come Baseboard Management Controller (#BMC), a dedicated, soldered on chip that changed server management from manual, physical troubleshooting to automated, isolated remote control. And it seemed pretty good.

And then pen testers and red teams started reporting flaws and vulnerabilities. For decades. Have those flaws been fixed in all those years?

No, don’t be ridiculous. Where’s the ROI for the MBA?

That said, if your bmc is exposed to the internet, you probably have way bigger #infosec issues.

So, #printers. Did you know there's an entire circle of #hell just filled with printers? And they all "worked just fine yesterday". Evil #sysadmins and #cybercriminals are sent there to fix them. Fun fact: printers aren't assembled in factories. They are simply summoned from that plane into our realm. If you ever though your printer is possessed by daemons, you were wrong. The printer IS the #daemon

System Administration: Week 13: Ethics and Social Responsibility (now with AI, oh boy!)

In this week's lecture, we discuss the professional codes of ethics in our field, some hairy ethical dilemmas encountered by #SysAdmins and other engineers, and how we can take an active role in acting in the public interest as part of our jobs.

There are a number of unsurprising parallels to a conference talk I gave way back at Velocity in 2015:

Java TLS has been a blind spot for eBPF-based #observability tools for years. JSSE runs entirely inside the JVM with no exported symbols and nothing to attach to.

Here is how to solve it: https://coroot.com/blog/java-tls-instrumentation-with-ebpf/

Benchmarking our eBPF Java TLS agent against OpenTelemetry, Coroot added only +15% CPU overhead vs +38% from OTEL, which dropped 20% of requests under load.
