This document explains the process on how we bring Ubuntu or Debian with SSSD / Kerberos / PAM to a state where it is on the domain and can authenticate users via SSH login. This process has been tested on Debian 11 "Bullseye" and Ubuntu 22.04 (Jammy Jellyfish). I tested this on a Server 2016 compatible active directory installation. In Active directory I created a group called "Linux_Admins" and placed all

Gentoo Linux HPPA on HP 9000 RP3440 with PA8800 Notes

doogie
Notes on Rp3440 Installation: The port console=stty1 needs to be specified because the serial is handed off from the main console to the passed through serial port. The disk partition layout needs to have the parisc boot partition in the beginning of the disk; type f0. This is where PALO is installed to. There then needs to be a separate ext2 formatted partition, also near the beginning of the disk,

Zoneminder Linux / mdraid Optimizations

doogie
I was looking at things on the new server that I had just setup today and I noticed that the SSD was being written to at a continuous 35MB/s. This was as a result of the zoneminder /var/tmp/zm being located on the primary disk. The solution was to add a line to /etc/fstab and dedicated an 8GB RAM disk to resolve my issue. The running occupied size for my setup

Converting a non raid root filesystem to a RAID 0 or 1, and SPARC

doogie
This isn't a how to post, so much as a reminder for myself on how I was able to accomplish this. I have Debian wheezy installed on one of my SunFire V240 servers, and I didn't setup the RAID root initially when I was tinkering around with the server. After some research and fidgeting I was able to get things working swell. Debian dropping support for SPARC is saddening, especially

pbzip2, Multithreaded bzip2 application

doogie
Since I have a MASSIVE amount of parallel processing at my disposal it can come in real handy when working with extremely large files. This week I recovered a full terrabyte drive that had a completely hosed NTFS partition on it. After dd'ing the entire disk into an image and recovering the files it's time to format the drive an put our recovered data back onto the disk. The corrupted
