Ram's Technology Notes
This is a brief introduction to setting up and running Virtual Machines in Linux. While there are several different options to accomplish this, my preferred method is using KVM + QEMU + LibVirt. Here’s what each of these does: QEMU is a full-fledged stand-alone emulator that can emulate all kinds of hardware for virtual machines…
This will be a place where I’ll track a running list of useful Linux utilities. convert <input_image> <output_image> ps2pdf <input_pdf> <output_pdf> cat <input_file> | tr ‘,’ ‘\n’ | tr -d ‘\[\”\] ‘
I finally followed through in setting up and sharing my Canon MP620 through my Linux homeserver with CUPS. This part is straightforward – install cups, cups-backend-bjnp (for the network communication with the MP620), gutenprint (for printer drivers) and then going to <host>:631 and adding the network printer using the printer’s static IP address (CUPS network…
As I mentioned here, I have been running Manjaro Linux on my home laptop for almost a year now and for the most part it has worked well. My setup is that most of the useful storage is on my home server and I was mounting these as SMB shares on the laptop. Initially, I…
After a pleasant year of using Manjaro Linux on my laptop at home, I started seeing problems with SMB mounts. My setup is that I have all of the main storage on my home server which is shared through SMB shares and these shares are mounted on the laptop through SMB4k. SMB4k started doing strange…
I have been running Manjaro Linux on my main home laptop for a change for the last 9 months. Overall, experience has been excellent with almost all the hardware working very well, battery life being very good, wake from sleep being near instantaneous and the laptop being very functional for my workload. I had however…
One of the key goals for my Ubuntu NAS was to have the ability to create a single storage pool out of all the disks in the NAS (OS is running off a USB thumb drive) and also provide some fault tolerance such that if a single disk failed, data wasn’t lost entirely. Even though…
As part of the reorganization of my home server, I am consolidating all my music files into the home server. I quickly realized that in a misguided fit of irrationality, I had gone through a phase in the past where most of my library was in the WMA format. The problem with WMA format is…
In my home setup, we have a mix of devices (Windows 8.x, Windows RT, Windows Phone, Linux, Android and iOS). As part of my home server setup, I’ve setup Samba to share folders with the other devices – there are a few subtleties with setting up the Samba shares so you can access them with…
I was looking at my logs and noticed that smbd had crashed a few times since install. Searched the samba bug database and found this bug which was reporting the same issue. I have applied the patch supplied and updated the package – here’s how I patched and updated: In your samba source folder, run…
