doogie
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

Debian 9 Stretch SSH logging to file with rsyslog

doogie
This is just a quick note, and this does apply to other systems that use rsyslog. Following these steps will help you setup your SSHD service so that all events are logged to a specific file of your choosing. Choose an unused local facility. For example local3 is not used for any logging in your system. So first edit /etc/sshd_config configuration file. #SyslogFacility AUTH SyslogFacility local3 Now configure rsyslog to log local3

So there are some folks who are still trying to run modern things on old SPARC machines still. I pulled out my old Solaris server that I used to host a backup of my website back in 2013, dusted it off and booted it up.The web services came up flawlessly, just as they had worked then.

Time for a new workstation, well… old new

After being in North Carolina for an extended 2.5 year hiatus I returned to a workstation that wouldn't boot until after the third or fifth attempt. Eventually after it got used

Howdy!   Alright, I must admit that it has been quite a while since I really have posted anything. There has been a lot going on, but finding time to sit down and write things isn't always easy. First off, the site has been moved off of Fookushima, the G5 Quad has been removed from service. Why did this end up being the case? Storage. With the limited wattage I

April Update 2016

The G5 quad is doing great. The system has been up for more than 175 days now after traditionally it crashing out after 30. I am currently running the stock cooling system until issues are resolved with the other one. Though, I'm out of town, so hopefully the factory one holds out well. I feel that it will since I am actually running the cooling system more aggressively than it

I have no problem with interacting online and sharing that information here, but if for some reason I were to no longer have an internet connection for any

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

How to Install IRIX from a Hard Drive

doogie
After getting more involved with SGI stuff as of lately I must admit it is a real bear to get IRIX loaded onto these puppies. This is for several reasons, one of which being I don't have an external SCSI CD-Rom drive always laying around. Maybe I do now,  but changing CDs and hoping that they'll be continually reliable is a farce. People in the past have suggested and discussed

Vintage Collection- SGI Fuel

doogie
Silicon Graphics Fuel The fuel by many was regarded as a later replacement for the O2. I think that it was definitely a more flexible and expandable workstation versus the O2, albeit still only a uni-processor system. The Fuel was also one of the SGI systems that more closely resembled a PC form factor. The tower is nothing more than a higher quality mid-tower ATX Chassis,  but the motherboard shares

Doogie, what the shibobbies are you doing to your site?

If you read my last post (if you were even able to) you'll notice that things have been slated for a change here on the server. Before moving any other websites to the virtual host configuration scenario I must do some testing first. I figured in this case it would be easiest to just monkey around with it on my production site, and it has produced some rather, well, interesting
