When I got my HP ML110 Gen9 working as a workstation I initially was under the impression that boot wasn’t supported on NVMe and booted it from USB. I found USB booting with legacy boot to be unreliable so decided to try EFI booting and noticed that the NVMe devices were boot candidates with UEFI. […]

I recently had to renew the SSL certificate for my web server, nothing exciting about that but Certbot created a new directory for the key because I had removed some domains (moved to a different web server). This normally isn’t a big deal, change the Apache configuration to the new file names and run the […] Kali is a Debian based distribution aimed at penetration testing. I haven’t felt a need to use it in the past because Debian has packages for all the scanning tools I regularly use, and all the rest are free software that can be obtained separately. But I recently decided to try it. Here’s the URL […] It seems that every cloud service of note has a free tier nowadays and the Oracle Cloud is the latest that I’ve discovered (thanks to r/homelab which I highly recommend reading). Here’s Oracle’s summary of what they offer for free [1]. Oracle’s “always free” tier (where presumable “always” is defined as “until we change our […] My first Linux system in 1992 was a 386 with 4MB of RAM and a 120MB hard drive which (for some reason I forgot) only was supported by Linux for about 90MB. My first hard drive was 70MB and could do 500KB/s for contiguous IO, my first Linux hard drive was probably a bit faster, […] I recently bought a couple of PowerEdge T320 servers, so now to learn about setting them up. They are a little newer than the R710 I recently setup (which had iDRAC version 6), they have iDRAC version 7. RAM Speed One system has a E5-2440 CPU with 2*16G DDR3 DIMMs and a Memtest86+ speed of […] I previously wrote about getting a Brother MFC-9120CN multifunction printer/scanner to print on Linux [1]. I had also got it scanning which I didn’t blog about. found USB scanner (vendor=0x04f9, product=0x021d) at libusb:003:002 I recently upgraded that Linux system to Debian/Testing (which will soon be released as Debian/Bullseye) and scanning broke. The command sane-find-scanner would […] I’m playing with a HP Proliant ML350P Gen8 server (part num 646676-011). For HP servers “ML” means tower (see the ProLiant Wikipedia page for more details [1]). For HP servers the “generation” indicates how old the server is, Gen8 was announced in 2012 and Gen10 seems to be the current generation. Debian Packages from HP […] Firstly a disclaimer, I’m not an expert on this and I’m not trying to instruct anyone who is aiming to become an expert. The aim of this blog post is to help someone who has a single kernel issue they want to debug as part of doing something that’s mostly not kernel coding. I welcome […] In the comments on my post about Load Average Monitoring [1] an anonymous person recommended that I investigate PSI. As an aside, why do I get so many great comments anonymously? Don’t people want to get credit for having good ideas and learning about new technology before others? PSI is the Pressure Stall Information subsystem […] |
