Mount exFat filesystem on Debian

ExFat file systems are not supported out of the box on Debian, but support is provided by installing the exfat-utils package:

# apt-get install exfat-utils

Reading package lists... Done

Building dependency tree       

Reading state information... Done

The following additional packages will be installed:

  exfat-fuse

The following NEW packages will be installed:

  exfat-fuse exfat-utils

0 upgraded, 2 newly installed, 0 to remove and 28 not upgraded.

Need to get 73.0 kB of archives.

After this operation, 295 kB of additional disk space will be used.

Do you want to continue? [Y/n] y

fdisk -l shows my usb disk as:

Disk /dev/sdc: 186.3 GiB, 200049647616 bytes, 390721968 sectors

Units: sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disklabel type: gpt

Disk identifier: ...

Device      Start       End   Sectors   Size Type

/dev/sdc1      40    409639    409600   200M EFI System

/dev/sdc2  411648 390721535 390309888 186.1G Microsoft basic data

So to mount sdc2:

mkdir /media/usbdisk (or whatever mountpoint you prefer)

mount -t exfat /dev/sdc2 /media/usbdisk

Done!

Proxmox installation on a 2008 Mac Pro

Following on from my earlier article, I read some more about Proxmox running on a Mac Pro so decided to give it a go.

I added an empty drive into one of the spare bays, and then booted from the Proxmox installer.

 

 

 

 

 

 

 

 

 

 

 

 

After first boot and logon with the default root user to the web interface:

The first VM I want to create is for CentOS, and I have the iso ready to go on an attached usb drive, which I copied to the isos dir on Proxmox (/var/lib/vz/template/iso – defined storage locations for images are covered in answers to this post). The image now shows up on the local storage:

Creating a new VM based on this image:

Starting up the image and starting the CentOS install using the web-based vnc access:

… after completing the install, success!

Downgrading nvidia drivers on Debian 8 to legacy version 304

I have an old HP desktop with onboard nvidia 6150 graphics, and I’ve posted before about installing  the legacy 304 drivers, and installing latest nvidia drivers to support an nvidia 750ti.

I recently moved the 750ti card into my 2008 Mac Pro, so now when booting the HP desktop into Debian with the latest nvidia drivers, Cinnamon crashes, and all I get is a default/low resolution display. So time to go the other way and downgrade back to the legacy 304 drivers (I won’t be moving the 750ti back to this machine).

Taking a gamble that I wouldn’t need to uninstall anything, I followed the steps in this post to install the 304 driver using this command:

aptitude -r install linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') nvidia-legacy-304xx-driver

This gave the error:

The following packages have unmet dependencies:
 nvidia-legacy-304xx-alternative : Depends: glx-alternative-nvidia (< 0.7) but 0.7.3~bpo8+1 is installed.

… accepting the yes option resulted in no changes, so I uninstalled the package it was complaining about:

sudo apt-get remove glx-alternative-nvidia

This removed a number of the previous 375 driver related modules that I had installed for the 750ti card.

Cleaned up anything no longer needed with:

sudo apt-get autoremove

and then rebooted, and success, back to regular 1920×1080 resolution

Installing FreeBSD 11.1 on Parallels

Installing FreeBSD from an ISO in a VM is pretty easy, just follow the menu prompts, set a root password and create a new user when prompted. There’s many step by step guides such as this one if you need help.

Out of the box with a fresh install you don’t get a desktop environment installed like you typically do with Linux distros, so after the first boot there’s a few additional steps to get up and running.

First install any updates  (logon as root):

freebsd-update fetch
freebsd-update install

Next install XWindows using pkg:

pkg install xorg

You can install any of the common desktop environments on FreeBSD. To install Gnome:

pkg install gnome3

After the install completes there’s a couple of manual config steps, which are covered in this guide here.

In summary:

  • add a line to mout /proc to /etc/fstab:
proc          /proc       procfs  rw  0  0
  • edit /etc/rc.config and add the following lines:
dbus_enable="YES" hald_enable="YES"
gdm_enable="YES"
gnome_enable="YES"

During my install of Gnome I ran into an error with corrupted package during install:

After some googling and trying a few different options (pkg clean -a), a post suggested to delete the download the downloaded cached package, but didn’t say how to do that. From some searching I found what looks like the cached files at /var/cache/pkg, so a ‘rm libwmf*’ deleted the file mentioned in the error that were previously downloaded, and then kicking off ‘pkg install gnome3’ again picked back up from where it left off.

Issues fixed, gnome installed, rebooted and we’re at the Gnome desktop:
