Linux

How I fixed the issue with non-intel trasceiver not working with Intel X520 network card. Intel trying to be smart and how to tell the card to get over itself.

FreeIPA is to linux as Active Directory is to Windows. Like AD for Windows, FreeIPA should have a replica for high availability. This is a walk though on how I got it setup and running in CentOS 8 LXC container on Proxmox VE server. Low resource demands compared to a dedicated vurtual machine.

Upgrade my workstation and now NFS mounts in fstab not mounting on boot but working with mount -a command works as expected. in short, systemd is worth learning and I cant believe ubuntu was released with such a basic bug.

Two years ago I began migrating looking at ways to use the Appleverse without Apple and extending collaborative features to Linux and open source. The solutions where technical and so “kludgy”. Time and need of the masses has now made this now near native and easy to implement.

My hard drives were spinning at 7600 RPM 24/7, this is fine for aa actual server for the masses or in DC, but total overkill for my intermittent needs. Why do I want power control over my spinning rust…spin down to save noise and heat = save energy.

IPMI is more then a way to access servers over the network without them powered up (lights out, out of band etc). It is an Intelligent Platform Management Interface, it can be used to interface with the hardware layer in ways the OS can’t. Let’s use it to control some fans.

dd has being my go to tool for “everything-imges-and-iso”, especially ever since the usb stick became ubiquitous and norm for installing new a OS. There is a new kid on the block now…but it needs a GUI.

The new trend in linux is the shift to netplan as a network manager that uses either NetworkManager or systemd-networkd to manage interfaces is pretty much the default now for Ubuntu Desktops. This breaks OVS and linux bridging, but there is a way

Continuing on with my theme of compiling and patching linux kernels. Let’s look at the Ubuntu way that creates a .deb file for use with apt package manager. Git work flow thrown in for free.
