user space access to parallel port

Posted 06-17-2012 at 09:53 PM by neonsignal

When using a parallel port for a printer, typically it will be accessed through a kernel printer driver.

However, the parallel port can also be used as a multi-purpose bit port from user space. This can be done by loading the ppdev driver:
Code:
modprobe ppdev
In the past, you would also have to create the access node, but this is now scripted and will happen automatically:
Code:
mknod /dev/parport0 c 99 0 -m 660

chironfs and sshfs: "mknod failed accessing..." error

I thought I'd post this for posterities sake:

chironfs is a nifty fuse-based file system that duplicates a file hierarchy across multiple paths. (Like a file system version of RAID 1.) However, I found that if I tried to use an sshfs mounted directory as one of the paths, chironfs disables the path with the error "mknod failed accessing <path> Permission denied".

The workaround I found was to pass in the following option to sshfs when mounting the sshfs...

user mounted filesystems

Posted 06-14-2012 at 10:51 PM by neonsignal

Rather than mount a filesystem as root (whether from the command line or through /etc/fstab), non-privileged users can make use of the fuse (filesystem in userspace) system. This requires the installation of the fuse-utils package, and the user has to be added to the fuse group.

There are a number of useful systems implemented on top of fuse.

For example, an ISO system might be required to run a particular application, and just mounted temporarily by the user executing...

Trying to Chain of Fools Fedora

Posted 06-14-2012 at 05:49 PM by wagscat123

I tried to perform a chain of fools style experiment (upgrading through every version of Fedora from 1 to 17) of Fedora in VirtualBox. It went great, chugging along right up through Fedora 1-8. Once I got to Fedora 9, the menu functions and keyboard input began to get weird, and by Fedora 10 the cursor froze upon X startup. I have ran into this issue when Chain of Foolin' around before in both SUSE and Fedora and couldn't get a solution (even when asking here). I might do a command prompt Chain...
